Sometimes we have difficulty knowing where to start. We want that new body, or want to be healthy and have more energy, but we just do not know what the first step is. In addition, the road to our goals is sometimes a rocky one. It is difficult to transgress and sometimes we just want to give up. We sometimes forget that our current situation did not occur overnight and so changing it will not happen overnight either. It will take time and hard work. Therefore, I suggest that you should set only one goal at a time.When you try to take on too much at once, you can become overwhelmed quickly. Create a list and take one goal at a time. Once you achieve that goal, back to your list to mark it off, and move to the next one. The act of achieving goals individually will give you a greater sense of accomplishment. You can even break the one goal into smaller parts. This gives you motivation and success more often than waiting for days or months to achieve a larger goal.B.

Language points1.Even a modest space voyage, Dyson calculated, would set the average family back 1,500 years in wages. <P ara.1>According to Dyson’s calculation, even a modest and common space voyage would cost the average family wages of about 1,500 years.set back: cost <a person> specific amounte.g. My new car set me back $3000.2.The difference reflected the relative difficulty of space travel, but also the limitations of big government programs to do things on the cheap.<Para.1>The cost difference not only has showed space travel is much more difficult than the Mayflower’s voyage in 1620 and the westward journey of the Mormons in 1840s, but also prove d that government needs to reduce its spending on big and expensive programs and turn its attention to the programs that cost less money.3.Nothing has happened in the past 40 years to suggest that NASA has come any closer to the commercial sweet spot of the Colonial settlers. <P ara.2> In the past 40 years, nothing has shown that NASA’s has found its best solution to which it could start and develop its business just like early colonial settlers who found their place, Massachusetts, to settle down and made their living move on based on their settlement.A sweet spot is a place, often numerical as opposed to physical, where a combination of factors suggests a particularly suitable solution. In the context of a racquet, bat or similar sporting instrument, sweet spot is often believed to be the same as the center of percussion. In this context, sweet spot means a financially profitable situation. Colonial settlers found this sweet spot while NASA didn’t come close.4.The commission headed by Lockheed Martin chairman Norm Augustine that has spent much of the past year deliberating on NASA’s human spaceflight program… <Para.2>deliberate on: to consider /discuss or negotiate仔细研究,审议e.g. We had no time to deliberate on the problem.5....even though ending this program would send NASA’s international partners into apoplexy. <P ara.2>…even though ending the ISS program would make NASA’s international partners feel very angry.The apoplexy is an outdated medical term, which can be used to mean "bleeding〞. It can be used non-medically to mean a state of extreme rage or excitement.6.More embarrassing, with NASA’s space shuttle due to be mothballed in 2010, and its cheaper replacement, the Orion capsule, not due to fly until 2012, the partners face a two year gap in which they will have to rely on Russia’s Soyuz ships to commute to the space station.<Para.2> To NASA’s embarrassment, they had to stop using their shuttle in 2010 and its cheaper replacement, the Orion capsule cannot fly until 2012, so there will be a two year gap between 2010 and 2012, in which NASA’s international partners have to depend on Russia’s ship to come and go to the space station.mothball: to decide not to use or develop something, for a period of time, especially a piece of equipment or a plan 封存;搁置不用If someone in authority mothballs a plan, factory, or piece of equipment, they decide to stop developing or using it, perhaps temporarily.7.The shortfall may force NASA to open up its space-exploration program to commercial operators to a degree that’s unprecedented in its history.<Para.3> The shortage or lack of money may force NASA to get commercial operators involved in its space-exploration program to a degree that has never happened before.shortfall:n. 缺口;差额;亏空If there is a shortfall in something, there is less of it than you need.8.The move could create opportunities for the modern equivalents of Young and Bradford—entrepreneurs willing to risk their livelihoods on making the exploration of space affordable by not only designing and building ships for3 / 434NASA, but also by providing shuttle services to deliver NASA astronauts or equipment to their targets. <Para.3>The move—NASA’s opening up its space program to commercial or private sectors— could create opportunities for upcoming modern entrepreneurs like Young and Bradford in the early times. They are willing to take a risk in spending much money, effort and even their lives on space exploration in order to get it started and moved on by not only designing and building ships for NASA, but also by providing shuttle services to deliver NASA astronauts or equipment to meet NASA’s targets. 9.In the past, NASA has been deeply involved in managing design and development work by outside contractors, a messy process that made the shuttle expensive and unsafe, rather than cheap and safe. Now the agency is under pressure to step back and buy services wholesale from private firms.<Para.3>In the past, NASA has spent much effort and time asking outside contractors to design and develop space shuttles, which is a very complicated process making the space shuttle expensive and unsafe rather than cheap and safe. Now due to financial pressure, the agency has stepped back to entrust private firms to do all the business for NASA.10."We’re talking about a movement from where the government has been the prime contractor, managing situationswith a very hands-on role, to a situation where they are just a customer,〞says Larry Williams. <Para.3> We are talking about the movement —NASA has shifted it role from a major contractor who needs to do every detailed and practical work by itself to a customer who buys services wholesale from private firms.11.The next step is to work out similar deals with private firms to send astronauts aloft. <Para.5> The next step is toenable the private firms to send astronauts to outer space just like cargo that can be delivered.aloft:adj./adv.high in the air 在空中高处Something that is aloft is in the air or off the ground.12.To do that, NASA will have to relinquish some of its oversight of crew safety. This isn’t entirely without precedent.<Para.5> In order to let private firms send astronauts into space, NASA will have to give uptheir responsibility of regulating crew safety. This has happened before.relinquish:vt.to stop having something, especially when this happens unwillinglyIf you relinquish something such as power or control, you give it up.oversight: the state of being in charge of somebody/something 负责;照管13.Space X claims it could adapt its cargo-carrying spaceship for ferrying a human crew in less than three years, once itgets the green light. <Para.6> Space X claims it could make some change to its spaceship so that it could send people to outer space in less than three years, once it gets permission.14.If Virgin and other commercial firms can deliver, Earth orbit will be far more accessible than it’s ever been before.Although it would still be a stretch for all but the wealthiest people, costs could come down low enough to jump-start markets for tourism. <Para.8> If commercial firms like Virgin Galactic can deliver man to Earth orbit, then Earth orbit would be much easier to get to than ever before. It would be open to nobody but the wealthiest people since only the rich can afford the high price,but the cost could be reduced so that it would become a rising market for tourism.15.The big sticking point, however, will be safety. Even though NASA holds the safety of its crew paramount, it stillhasn’t been able to escape the occasional disaster, like the loss of the Columbia shuttle and its crew in 2003. <Para.8> The key point is still the consideration of safety of its crew. Even though NASA regards the safety of its crew as the most important thing, it still hasn’t been able to avoid the occasional disaster, such as the loss of the Space shuttle, Columbia andits 7 crew members in 2003.16.…the space shuttle is unreliable, in part, because its all-purpose design is overly complex. NASA needs a biggerrocket capable of sending a crew, with equipment and supplies for a long-duration trip, beyond the tether of Earth’s gravity. <Para.9>… the space shuttle is unreliable partly because its space shuttle is designed for all- around purposes, such as carryingcargo or people, etc. And the process of design is extremely complex. NASA needs a bigger rocket capable of sending a crew, with equipment and supplies for a longer trip, beyond the limitation or influence of Earth’s gravity.overly: too/ extremely17.It might be able to entice commercial firms to undertake their own big rockets if there were some payoff down theroad. <Para.9> Private firms might be attracted to build their own rockets to deliver astronauts to outer space if they could get profits..payoff:n. return; reward; payment18.Many seemingly ridiculous ideas for generating energy and beaming it back to Earth now seem much less so, thanksto the climate crisis. <Para.9> The ideas of generating energy and shining it back to earth, which used to sound very funny, but now seems much possible and necessary due to the consideration of the climate crisis.19.…the challenge of sending people safely into deep space and back for a profit is big enough to give any entrepreneurpause. <Para.10> … the challenge for private services to send people safely into deep space and back for making profits is so big that any entrepreneur would hesitate before they take their steps.give sb./sth. pause:使踌躇,使犹豫This finding should give pause to it. 这个发现令人深思.His recent behavior has given her pause about their relationship.他最近的行为让她对他们的关系产生了犹豫.20.The Industrial Revolution didn’t take off until the railways arrived. <Para.11>Here it means that the private sector will play an important role and do lots of work in deep space only if NASA gets it started.III. Key to the exercises1. Reading comprehension<1> In early times there was an essay comparing space travel to the colonization, but nothing can keep Dyson from makingameticulous effort to quantify and compare the costs of these vastly different ventures.<2>By presenting the relationship between FedEx and the U.S. Postal service, the writer wants to showthat NASA actually canpay private firms, like Space X to design and develop space program.<3>NASA opened up its space exploration program to commercial operators because NASA lacksfunding to keep its humanspaceflight program moving on and operating. So, it is the shortfall that forces NASA to open up its space-exploration program to commercial operators.<4>There are two steps that NASA is going to take after it begins working with smaller companies.The first is to get cargodelivered to space; the next step is to work out similar deals with private firms to send astronauts aloft.<5>Give your own comments.2.

The U.S. Congress, alarmed by the perceived threat to U.S. security and technological leadership <known as the "Sputnik crisis〞>, urged immediate and swift action; President Dwight D. Eisenhower and his advisers counseled more deliberate measures. Several months of debate produced an agreement that a new federal agency was needed to conduct all non-military activity in space.

The utilitarian doctrine is, that happiness is desirable, and the only thing desirable, as an end; all other things being only desirable as means to that end.<Para. 1>The utilitarian principle is that happiness is worth obtaining and is the only thing worth obtaining as a purpose; all other things being so only as a way to obtain happiness.2.What ought to be required of this doctrine, what conditions is it requisite that the doctrine should fulfill, to make good its claim to be believed?<Para. 1>What requirements should this principle meet, what are the necessary conditions this principle should accomplish to make its claim good for people to believe?requisite a. required by circumstances or necessary for successe.g. Have you the requisite visa to enter Canada?have/lack the requisite capital to start a business3.In like manner, I apprehend, the sole evidence it is possible to produce that anything is desirable, is that people do actually desire it.<Para. 2>Likewise, I think the only evidence we can possibly offer to prove anything to be desirable is that people do actually desire it.apprehend v. grasp the meaning of <sb./sth.>; understande.g. Do I apprehend you aright, i.e. Do you mean what I think you mean?sole a. one and only; singlee.g. the sole cause of the accidentthe sole survivor of the crash4.If the end which the utilitarian doctrine proposes to itself were not, in theory and in practice, acknowledged to be an end, nothing could ever convince any person that it was so.<Para. 1>If the purpose which the utilitarian doctrine itself intends to fulfillwere not accepted to be a purpose both in theory and in practice, then nothing could ever make anyone believe that it was so.5. No reason can be given why the general happiness is desirable, except that each person, so far as he believes it to be attainable, desires his own happiness.<Para. 2>We can give no reason why the general happiness is desirable except that each person desires his own happiness as long as he believes that it can be achieved.attainable a. that can be attainede.g. These objectives are certainly attainable.6.This, however, being a fact, we have not only all the proof which the case admits of, but all which it is possible to require, that happiness is a good, that each person’s happiness is a good to that person, and the general happiness, therefore, a good to the aggregate of all persons.<Para. 2>However, it is a fact that the general happiness is desirable, and we have not only all the evidence that the case agrees with, but all the evidence that it is likely to need,to prove that happiness is a benefit, that each person’s happiness is a benefit to that person, and the general happiness, therefore, a benefit to all persons as a whole.aggregate n. total amount; mass or amount brought togethere.g. the complete aggregate of unemployment figures7.Now it is palpable that they do desire things which, in common language, are decidedly distinguished from happiness. <Para. 3>Now it is obvious that people do desire things which, in everyday words, are definitely different from happiness. palpable a. clear to the mind; obviouse.g. a palpable lie, errordistinguish v. recognize the difference between <people or things>e.g. People who cannot distinguish between colours are said to be colour-blind.The twins are so alike that no one can distinguish one from the other.8.They desire, for example, virtue, and the absence of vice, no less really than pleasure and the absence of pain.<Para.3>For example, they want to have virtue and avoid vice as much as they want to have pleasure and avoid pain.vice:n. evil or unprincipled conduct; wickednesse.g. Greed is a terrible vice.9.The desire of virtue is not as universal, but it is as authentic a fact, as the desire of happiness. <Para. 3>Although the7 / 43。

58CHINA TODAYAROUND the time the Chinese celebrate the Spring Festival, a time of family reunions and feasting, South Africa cele-brates the birth of its wine industry. It is a happy serendipity as the South African wine industry has found a rising market in China, and the Spring Festival is the time when it surges higher still.On February 2, South African vint-ners raised a toast for the 363rd birth-day of their wine industry, the only one in the world to have an official historical birthday for the industry. The record of the first wine made in South Africa is found in the diary of Johan Anthoniszo-on van Riebeeck, an employee of the Dutch East India Company, who arrived in 1652 to take up his post.He is credited with establishing a vineyard in today’s Cape Town to pro-duce red wine, which people once be-lieved prevented scurvy. The entry in his diary on February 2, 1659 reads, “Today, praise be to God, wine was made for the first time from Cape grapes.”Subsequently, the new year became synonymous with grape harvesting, and a wine harvest commemoration became part of the local traditions.In contrast, France started making wine in the 5th century B.C. So perhaps it is no wonder that French wine domi-nated China’s imported bottled wine market till as recently as 2015, account-ing for 42 percent of the total volume and 46 percent of the total value.However, a rival that had started to make wine much later – just around the 19th century – was beginning to catch up: Australia.By 2019, Australian wine brands had captured over 35 percent of the Chi-nese market, relegating French wine to second place at about 29 percent. Market watchers attributed this to the China-Australia Free Trade Agreement that came into force in December 2015, slashing tariffs, Australia’s closer prox-imity, and the surge in Chinese students and tourists in Australia, who sampled Australian wines and introduced them back home. That year, the market share of South African wine in China was less than 1 percent.However, things began to change drastically in 2020. China-Australia bilateral ties soured and China started imposing tariffs on a range of Australian goods, from barley to mining products. There was also an anti-dumping investi-gation into Australian wine following a complaint. After initial tariffs of 107-212 percent on Australian wine from March 26, 2021, they were raised to 116-218 percent, a measure that will remain in place for five years.The results have been dramatic.While Australian wine companies reeled under almost 94 percent loss in the China market compared to 2019, South African wine has seen over 100 percent increase compared to 2019. Compared to 2020, it is a staggering leap of nearly 190 percent, according to data from the Wines of South Africa (WoSA), a non-profit organization promoting the ex-port of wine from South Africa.The opportunity created by the re-strictions on Australian wine has been a lifeline for the South African wine in-dustry that has suffered lockdowns and four periods of bans on domestic sales during the pandemic, resulting in the loss of 21,000 jobs by October 2020, ac-cording to WoSA.As South African wine makers set their hopes on the China market, Marcus Ford, Asia market manager at WoSA, re-mains optimistic about the future even if China and Australia decide to make up. “There is still tremendous potential for South African wine companies to grow in China irrespective of any geo-political issues,” he said, “Our strategy is to work with both producers in South Africa and importers here [in China] to push and promote the category. We have tripled our market shares over the past 18 months, so that is obviously very encouraging.”WoSA runs several programs in Chi-na throughout the year to raise ChineseIn Good Spiritsaustralia’s loss of the china wine market has been south africa’s gain. But can it be sustained?By SUDESHNA SARKAREconomy /gEtting down to BusinEssCopyright ©博看网. All Rights Reserved.consumers’ awareness of South African wine and introduce more wine makers. Despite the pandemic and travel restric-tions, their annual roadshow continued last year, bringing 36 wine producers and more than 350 types of wine to Bei-jing, Shanghai, Shenzhen, Chengdu and Xiamen in autumn. It also attended ma-jor expos such as the China Internation-al Import Expo in Shanghai. In addition, WoSA also hosts smaller targeted wine tastings with wine clubs and groups. Ford says the two peak periods for sales in China are the Mid-Autumn Fes-tival in September and the Lunar New Year around late January and early Feb-ruary. However, “given that there are still some restrictions in place about large group gatherings and banquets, I think sales will be somewhat muted during the period.”Julian Johnsen’s entry into viticulture has a historical date. Originally from Hampshire in England, he decided to go into viticulture after studying agricul-ture at the Royal Agricultural University in Gloucestershire and bought his first farm in Western Cape in 1990, the same year Nelson Mandela was released from prison after 27 years of imprisonment. His Vondeling Wines is looking for “good reliable partners” to help them increase their footprint and develop in China. Last year, Vondeling shipped ap-proximately 10,000 bottles of their des-GDP growth, which stood at 8.1 percentin 2021. With “more people earningenough money to afford buying winemore regularly, the industry will con-tinue to grow,” he said.Ford thinks over the past years themarket has consolidated, “In 2016, therewere almost 12,000 importers, nowthere are approximately 5,500 – this in-dicates that those [who] have survivedare more serious, professional, and long-term, which bodes well for the future…You need to be patient because it takestime and investment to build brandshere. For producers and importers withthe appetite, the future is very bright!”Meanwhile, he has several sugges-tions on how to improve South Africanexports. As he outlined on the ChinAfri-ca Project, free trade agreements withthe main consuming countries wouldbring down costs, which is a majorconsideration.E-commerce platforms are also oneof the best ways to catch the eye of Chi-nese buyers. “Harnessing the power ofe-commerce platforms as the Chinesemiddle-class continues to expand canpromote our products and further oursales,” he said on the website. CSUDESHNA SARKAR is a journalist and editorbased in Beijing. A former commentator fora regional program of Deutsche Welle Radio,she follows China’s development, culture, andinternational links.ert wine Muscat de Fontagne and about5,000 bottles of the red wine Pinotage.Johnsen thinks South African winestill needs to be further recognized byChinese consumers as its great valuehas not been widely known yet. “Bestbang for your buck, choose South Afri-can any day, especially the higher ratedwines producers,” he said. “We reallyneed to market ourselves better in Chi-na and get consumers to try our wine.What would help us more is if we couldattract more Chinese tourists to comeand visit South Africa.”He also runs a period hotel, a reno-vated 18th-century Dutch farmhouse insylvan surroundings of South Africa thatcan sleep 14. “We would love to enter-tain more Chinese tourists,” he says, “Wedo not see many currently.”Like Johnsen, Ford also mentions thechallenge of finding reliable partners.“The major challenge in China is that[the China wine market] is still develop-ing and it’s really only 10 years old interms of having a significant scale,” hesaid. “This means that there are lots ofnew importers working with wine whohave very little experience. Since wine isa rather complex product, finding a reli-able, knowledgeable, and experiencedimporter or partner is still very challenging.”Despite the various challenges, hethinks the market potential for winein China is huge given China’s strongCopyright©博看网.

高中英语课外听力素材:West Africans, Free Markets andthe '08 Food CrisisThis is the VOA Special English Agriculture Report.Suppose you eat rice every day. But one day you go to the store and discover that the price is more than you can pay.That happened to millions of people two years ago at the height of the world food crisis.Between April of two thousand seven and March of two thousand eight the price of rice doubled in many places.Economists blamed the crisis on different causes, including high energy costs, bad weather and the use of food-crop lands for biofuel production.High food prices pushed more people in developing countries into poverty and hunger. Some researchers say people living in cities in West Africa may have suffered most of all.Geographers from three American colleges did a study that will appear in the Proceedings of the National Academy of Sciences. William Moseley of Macalester College in Minnesota led the study.The team looked at thirty years' worth of information on food security and agricultural policy in Gambia, Ivory Coast and Mali. Most of the research centered on rice, an important crop in those three West African countries.The researchers say Gambia and Ivory Coast suffered more during the food crisis than Mali did.They say this was because people in Gambia and Ivory Coast had come to depend on imported rice.Local rice production fell after the countries reduced farm supports and import taxes under free market reforms. That meant rice farmers were not only earning less but facing greater competition from imports. Then, when the food crisis hit, the cost of foreign rice shot up.The researchers say Mali suffered less because it depended less on imported rice, in part because of geography. Mali is not a coastal country with ports like Ivory Coast and Gambia.Laurence Becker from Oregon State University says after gaining independence, African nations tried to help farmers. Governments provided low-cost seeds and fertilizers. They built processing mills and roads to market. And they protected their markets with high tariffs on imported food.But by the late nineteen seventies and the nineteen eighties, those countries no longer had much money to help farmers. So they changed policies and tried another way to improve agriculture. Governments and major lenders like the World Bank and the International Monetary Fund turned to free market policies.We'll talk more next week about how the researchers link that change to the effects of the recent food crisis.And that's the VOA S pecial English Agriculture Report, written by Jerilyn Watson. I’m Steve Ember.。
The Columbian ExchangeThe Columbian Exchange (also sometimes known as The Great Exchange) has been one of the most significant events in the history of world ecology, agriculture, and culture. The term is used to describe the enormous widespread exchange of plants, animals, foods, human populations (including slaves), communicable diseases, and ideas between the Eastern and Western hemispheres that occurred after 1492. Many new and different goods were exchanged between the two hemispheres of the Earth, and it began a new revolution in the Americas and in Europe. In 1492, Christopher Columbus' first voyage launched an era of large-scale contact between the Old and the New World that resulted in this ecological revolution: hence the name "Columbian" Exchange.The Columbian Exchange greatly affected almost every society on earth, bringing destructive diseases that depopulated many cultures, and also circulating a wide variety of new crops and livestock that, in the long term, increased rather than diminished the world human population. Maize and potatoes became very important crops in Eurasia by the 1700s. Peanuts and manioc flourished in tropical Southeast Asian and West African soils that otherwise would not produce large yields or support large populations.This exchange of plants and animals transformed European, American, African, and Asian ways of life. Foods that had never been seen before by people became staples of their diets, as new growing regions opened up for crops. For example, before AD 1000, potatoes were not grown outside of South America. By the 1840s, Ireland was so dependent on the potato that a diseased crop led to the devastating Irish Potato Famine. The first European import, the horse, changed the lives of many Native American tribes on the Great Plains, allowing them to shift to a nomadic lifestyle based on hunting bison on horseback. Tomato sauce, made from New World tomatoes, became an Italian trademark, while coffee from Africa and sugar cane from Asia became the main crops of extensive Latin American plantations. Also the chili / Paprika from South America was introduced in India by the Portuguese and it is today an inseparable part of Indian cuisine.Before the Columbian Exchange, there were no oranges in Florida, no bananas in Ecuador, no paprika in Hungary, no tomatoes in Italy, no pineapples in Hawaii, no rubber trees in Africa, no cattle in Texas, no burros in Mexico, no chili peppers in Thailand and India, no cigarettes in France and no chocolate in Switzerland. Even the dandelion was brought to America by Europeans for use as an herb.Before regular communication had been established between the two hemispheres, the varieties of domesticated animals and infectious diseases were strikingly larger in the Old World than in the New. This led, in part, to the devastating effects of Old World diseases on Native American populations. The smallpox epidemics probably resulted in the largest death toll for Native Americans. Scarcely any society on earth remained unaffected by this global ecological exchange.Answer the following questions in complete sentences.1. What is the Columbian Exchange?2. What was exchanged?3. How did the Columbian Exchange affect society?。

REFERENCES (29)CHAPTER 1LITERATURE OVERVIEW“Other seed fell among thorns and the thorns grew up and choked them”Matthew 13:7KwaZulu-Natal (KZN) is one of the nine provinces of the Republic of South Africa, characterized by the Great Drakensberg Escarpment to the west and the Indian Ocean to the east. Most of the mean annual rainfall of 845 mm is received during the summer months (October-March) with the mean maximum and minimum temperatures reaching 25.2−30.4°C and -1.4−10.7°C, respectively. An average of 6.1−7.2 hours of sunshine is received in summer (Kars et al., 1999). Growing conditions are more favourable for crop production compared to most of the other provinces. Smaller areas of maize (Z ea mays), soyabeans (Glycine max), dry beans (Phaseolus vulgaris) and potatoes (Solanum tuberosum) are planted in KZN, yet higher yields per hectare are produced compared to provinces with bigger production areas. On average 4.4 tons ha-1 of maize are produced in KZN (4.6% of the total maize production) compared to the 3.0 tons ha-1 in the Free State Province which has 38% more land planted to maize (Anonymous 2005).However, not only is maize the second most important field crop besides sugarcane (Saccharum officinarum) in KZN, it also forms part of the agricultural activities that provide 60% of the rural population in the province with food security and a sole or complementary income. Some of the factors that affect agriculture and rural development include poverty, high input costs, uneconomical farm sizes and the quality and quantity of produce (Kars et al., 1999). For instance, for a conservation tillage maize farmer in KZN to make a profit in 2010, more than nine tons of yellow maize per hectare, valued at R1255 ha-1 (US$1=R7), had to be produced (Whitehead & Archer 2008). Because weeds are one of the major pests in most cropping systems, it contributes not only to the higher input costs, but to the overall quantity and quality of produce. If weedinterference could be minimized not only could it lead to obtaining higher yields but also contribute to food security.1. WEED MANAGEMENTThere is a close association between weed growth and crop production. Moss (2008) stated that the primary objective of weed management should be to better understand this association in order to improve current weed management and control programmes. Weed control is generally directed at controlling weed seedlings, not only because they are more manageable but weeds become less competitive later in the season. Amaranthus palmeri (Palmer amaranth) reduced maize yields between 11 and 91% as amaranth densities increased from 0.5−8 plants m-1 row (Massinga et al., 2001), while with Echinochloa crus-galli (barnyard grass) interference, maize yield loss ranged between 26 and 35% when barnyard grass emerged early. Yield loss due to the latter weed was only 6% when it emerged later in the maize growth season (Bosnic & Swanton 1997).The development of herbicides during the late 1940s and onwards, provided a simple solution to weed control, resulting in higher crop yields. Currently however, this reliance on chemical control has been critically scrutinized due to the development of herbicide resistance, the negative impact on food and environmental safety, the growth in the organic food production sector (Bastiaans et al., 2008) and shifts in weed populations (Buhler 2002). In addition, the availability and less complicated management of weeds with herbicides in comparison to other methods, gives the impression that weeds can easily be controlled after crop establishment and therefore cultural and tillage methods are in many instances not considered.Arguments against this simplification of weed management and the reliance on one weed control method have recently been published (Liebman & Davis 2000; Buhler 2002; Bastiaans et al., 2008). More emphasis should be placed on reducing weed densities, preventing weed reproduction minimizing weed competition and manipulating the crop competitiveness with the weeds. Weed emergence anddensity can be reduced through crop rotations, restricting light from reaching the soil surface, the formation of a physical barrier and preventing seed dispersal. Crop competitiveness can be enhanced through modification of the planting date to ensure crop emergence before the weeds, improved cultivars for rapid germination and root development, quicker canopy closure, increased planting populations (Bastiaans et al., 2008) and using allelopathic crop cultivars (Belz 2004; Khanh et al., 2005). Conservation tillage, together with the use of cover crops, are two important factors in adjusting existing weed management systems aimed at reducing weed fitness and improving crop yields.2. CONSERVATION TILLAGEAlthough the primary objective of tillage operations is to prepare a crop seedbed and not weed control, tillage influences weed seed germination by reducing the soil surface cover, it changes the soil temperature and moisture patterns, and it alters weed seed distribution in the soil profile (Locke et al., 2002). Land users in South Africa are obliged by law to adhere to the Conservation of Agricultural Resources Act of 1983 to conserve natural resources by, among other things, combating and preventing soil erosion and maintaining the production potential of the soil. Methods such as conservation tillage, suitable conservation works and avoidance of cultivation during periods of high erosion hazard are advised (Russell 1998). Conservation tillage makes use of crop residue left on the soil surface to reduce the impact of raindrops on the soil surface and to reduce the velocity of surface runoff. In KZN, conservation tillage is practised as direct drilling when a blade cuts through the crop residue, opening a furrow into which seed and fertilizer are deposited. It has several advantages over conventional tillage systems as it reduces soil erosion, soil compaction, energy requirements, evaporation and runoff (Russell 1998; Giller et al., 2009).These advantages came at a cost to weed management as the increased complexity thereof requires a higher level of management. According to Locke et al. (2002) careful management with herbicides is required as more post-emergence herbicides could be needed if the weeds were allowed to establish aftercrop planting. The introduction of herbicide-resistant genetically modified (GM) crops improved weed control options for conservation agriculture and it could be economically viable if only post-emergence herbicides were used (Reddy 2001). There is, however, a possibility that with the continued use of these GM crops and the limited seed migration into the field, traits such as herbicide resistance could evolve faster than under conventional tillage (Martínez-Ghersa et al., 2000).Also, weed populations and seed bank dynamics can be altered by conservation tillage. Most of the weed seeds occur in the upper 10 mm of soil and very few below 100 mm (Buhler 1995; Peachy et al., 2004). Small-seeded annual broadleaf and most grass species have the ability to increase prolifically because they germinate and become established when the seeds are at or near the soil surface. Summer annual species that do not require burial for establishment are also well adapted to proliferate (Buhler 1995). Conventional tillage appears to favour Digitaria sanguinalis (crab finger-grass), Sorghum halepense (Johnson grass) and Tagetes minuta (khaki weed), whereas conservation tillage promotes E. crus-galli (De La Fuente et al., 1999), Amaranthus retroflexus (redroot pigweed), Setaria viridis (green foxtail) (Buhler 1992), Chenopodium album (common lambsquarters) and Solanum nigrum (black nightshade) (Barberi & Mazzoncini 2001). Perennial weed populations tend to increase (Giller et al., 2009) and be more diverse (Locke et al., 2002) under conservation tillage. In KZN, Cyperus esculentus (yellow nutsedge), among others, can become a dominant and difficult weed to control in conservation tillage if insufficient weed control is practiced (Fowler 2000).3. CYPERUS ESCULENTUSCyperus esculentus is an herbaceous perennial weed which can be identified by an above-ground triangular stem-like fascicle of leaves which later develops into a solid triangular rachis. Thin rhizomes and roots develop from bulbs situated at the base of the fascicle. Rhizomes consist of elongated internodes and nodal cladophylls which differentiate into tubers and shoots (Wills et al., 1980; Stoller& Sweet 1987). C. esculentus spreads mainly through germinating tubers, and not as effectively by sexually produced seeds, which are viable and have longevity, but seedlings lack the vigour for survival in field situations (Stoller & Sweet 1987; Lapham & Drennan 1990).In most soils, the rhizomes of C. esculentus are concentrated in the upper 15 cm of soil, resulting in 80% and more of the tubers occurring in this zone. Very few tubers are found below 20 cm (Friesen & Hamill 1977; Stoller & Sweet 1987). Day length determines the vegetative and reproductive growth of C. esculentus periods of 8−12 hours promote tuber formation, and 12−16 hours are conducive for vegetative growth (Friesen & Hamill 1977; Williams 1982). Tubers are formed four to six weeks after seedling emergence (Stoller & Sweet 1987).During dormancy, storage conditions influence tuber sprouting, as cool moist conditions are more favourable than dry conditions (Friesen & Hamill 1977). Differences in tuber germination and multiple sprouting are not correlated with tuber weights but tuber size does influence seedling vigour (Stoller et al., 1972; Thullen & Keeley 1975). During tuber sprouting, one or more of the buds on the tuber begin to grow. A tuber can have more than one sprout forming, while others stay dormant. The number of sprouts decreases after each germination. More than 60% of the dry weight and nutrients in the tuber are used for the initial sprouting, 6−18% during the second and 2−10% during the third sprouting (Stoller et al., 1972; Thullen & Keeley 1975). Removing sprouts at regular intervals reduces the shoot numbers and tuber longevity, especially when done at four-week intervals (Thullen & Keeley 1975; Stoller & Sweet 1987).3.1 C. esculentus interference with crop productionCyperus esculentus interference with crop production has been demonstrated by various authors. Cotton (Gossypium hirsutum) yields decreased linearly with an increase in C. esculentus densities. Regression equations revealed an average yield loss of 19 kg ha-1 for each additional initial tuber m-1 of crop row (Moffett & McCloskey 1998), and approximately 18 kg ha-1 for each additional nutsedgeplant m-2 (Patterson et al., 1980). C. esculentus competition with cotton for the entire growth season reduced yields more than if the weed was present for shorter periods of time.Stoller et al. (1979) reported that, although variability was seen from year to year, average maize yield losses were 8% for every 100 shoots m-2.Yield reductions were more prominent in years when lower than normal rainfall was received during the growing season. Jooste and van Biljon (1980) found that the second sprouting of C. esculentus on the Mphumalanga Highveld in South Africa competed more with maize during the 8−16 week period than in the 0−8 week period. Maize yields were reduced by 11.4% on a Hutton soil (dry soils) and by 23.9% on an Avalon soil form (relatively wet soils). They concluded that it was possible that the first flush of nutsedge may reduce maize yields more than what they reported. Reinhardt and Bezuidenhout (2001) found that maize emergence was retarded in soil where C. esculentus grew for 28 days and then removed on the day the maize was sown. Maize was not affected if tubers and maize seeds were planted at the same time.Cucumber (Cucumis sativus) yields were reduced when 15 or more C. esculentus plants m-2 grew with the crop. However, the cucumber plants were able to compete successfully with C. esculentus if the crop was seeded at optimum densities, producing an optimum stand (Johnson III & Mullinix Jr 1999). The shoot dry weight of tomatoes (Lycopersicum esculentum) were reduced by 34% due to C. esculentus competition, with no differences in the interference from below- and above-ground competition (Morales-Payan et al., 2003).Little and van Staden (2003) reported that C. esculentus was the main competitor for water and nutrients with an Eucalyptus hybrid clone, Eucalyptus grandis x E. camaldulensis in Zululand, South Africa, directly after planting, with a subsequent reduction in tree growth. Aqueous extracts of tubers and foliage of immature and mature C. esculentus plants inhibited the growth of the essential ectomycorrhiza, Boletus maxaria on agar medium isolated from patula pine(Pinus patula) roots (Reinhardt & Bezuidenhout 2001). Their findings proposed that the interference of C. esculentus with seedling development of patula pine was indirect, through the primary inhibition of the ectomicorrhizal symbiont B. maxaria by allelochemicals released from the weed.Although Jangaard et al. (1971) did not investigate the allelopathic effects of C. esculentus, they identified certain phenolic compounds in the tubers that are known for their allelopathic potential. Compounds identified included p-coumaric, ferulic, p-hydroxybenzoic, syringic, vanillic, salicylic, protocatechuic and caffeic acids, with p-coumaric and ferulic acids in higher concentrations. Allelopathic effects were suggested when extracts and dried material of C. esculentus and C. rotundus (purple nutsedge) reduced the growth of cereals, vegetables and soyabeans (Tames et al., 1973; Meissner et al., 1979; Drost & Doll 1980).3.2 Control measures for C. esculentusShading reduces the total number of shoots and tubers, dry weight, plant height and leaf area of C. esculentus due to its C4 photosynthesis pathway. C. esculentus growth was significantly increased when plants were removed from the shade into full sunlight (Patterson 1982). Both Keeley and Thullen (1978) and Santos et al. (1997) found that 20−30% shade was detrimental to growth. In contrast, Jordan-Molero and Stoller (1978) reported that 30% shade did not influence the weed’s growth. Various crops planted at different plant populations reduced the above-ground growth of C. esculentus due to the low intensity of light reaching the weed. Ghafar and Watson (1983) showed that increasing the maize population from 33 300 to 133 300 plants ha-1 significantly reduced the C. esculentus above-ground biomass, tuber number, weight and height at the end of the growing season, with a concomitant significant increase in maize yield. Maize, barley (Hordeum vulgare), hemp (Cannabis sativa) and stooling rye (Secale cereale) reduced the above-ground biomass and density of C. esculentus secondary shoots in comparison with when a crop was absent (Lotz et al., 1991).Crops that create a regime of low light intensity during a long C. esculentus growth period suppressed tuber formation more strongly than crops that shadow the weed for a relatively short period of time (Lotz et al., 1991). Various other authors confirmed that shading suppresses tuber formation (Jordan-Molero & Stoller 1978; Keeley & Thullen 1978; Patterson 1982; Li et al., 2001). However, according to Stoller et al. (1979), maize planted in 75-cm rows did not provide enough shade to prevent C. esculentus from producing tubers. This is supported by Santos et al. (1997). Reductions in total leaf area were primarily the result of less leaves produced, as well as them being thinner compared to those in full sunlight (Patterson 1982). Thomas (1969) found that temperature had the greatest effect on C. esculentus tuber survival, while the duration of desiccation did not significantly influence tuber survival. A combination of temperature and humidity was more effective in killing tubers than either treatment alone.Although Stoller and Woolley (1983) and Stoller and Sweet (1987) stated that mulching would not be effective for growth suppression because the leaves of C. esculentus have sharp tips that could penetrate hard surfaces, Webster (2005) found that pots covered with 32 µm black-opaque and colourless-clear polyethylene mulches restricted nutsedge growth, as very few shoots emerged through the mulch. The biomass of C. esculentus shoots under the mulch was lower compared to the non-mulched treatment, with shoots under the black having a greater biomass than those under the clear mulch. Both mulches reduced tuber production to nearly half of the non-mulched control. Ormeño-Núñez et al. (2008) concluded that a dense stooling rye mulch between rows in a vineyard reduced C. esculentus growth by 81%.The limitation of herbicide options for C. esculentus control in conservation agriculture and the variability of chemical control (Jooste & van Biljon 1980), creates the opportunity to incorporate the use of cover crops in a weed management system to reduce the weeds’ fitness in order to increase crop competitiveness4. COVER CROPSIf the reliance on herbicides for weed management is reduced or eliminated, weed suppression must be approached from a crop cultivation perspective. Interest in the use of cover crops has been motivated primarily to produce crops in a more environmentally sustainable manner. Some of the benefits of cover crops include improving water infiltration, soil structure, reducing soil erosion, releasing nutrients upon decomposition, increasing the soil organic matter and preventing the leaching of N from the previous season (Liebman & Davis 2000). Cover crops can be grown in rotations after the main crop has been harvested or could grow simultaneously during part or all of the main crop season. For the purpose of reducing C. esculentus growth in a maize conservation tillage system in KZN, the term cover crop refers to crops planted in autumn after the main crop has been harvested and then killed during the following spring before planting the next main crop into the residues. The cover crop residues remaining on the soil surface could suppress weed growth through environmental and chemical interference.4.1 Weed suppression due to environmental interferenceSeed germination is dependent on adequate, but not excessive, supply of water, suitable oxygen:carbon dioxide ratio, and optimum temperatures and light (Monaco et al., 2002). Cover crop residues remaining on the soil surface can physically modify the germination environment by intercepting light and rain and interfering with the heat and water transfer between the soil and atmosphere (Teasdale et al., 2007).Exposure to light is one of the basic requirements of many weed seeds to germinate. Residues on the soil surface would intercept the incoming radiation promoting dormancy of species with a light requirement. According to Teasdale and Daughtry (1993) light transmission was more obstructed by live hairy vetch (Vicia villosa) plants than desiccated hairy vetch material, influencing the suppression of weed growth. Changes in the light spectrum reaching the seed under plant residue could affect the light quality, thereby suppressing germination and growth of photo-dormant species (Teasdale & Mohler 1993). Redlight converts phytochrome to an active form, promoting germination, while far-red light inactivates phytochrome, thus inhibiting germination. Most weed seeds germinate when exposed to the red light portion of sunlight and not in darkness. However, desiccated cover crops have limited influence on the red:far red light ratio due to the absence of chlorophyll (Teasdale & Mohler 1993).Plant residues on the soil surface lower the soil surface temperature by acting as insulation from the air temperature and intercepting solar radiation thus delaying cooling of the soil surface more than heating (Teasdale & Mohler 2000). Not only could germination be delayed at lower maximum soil temperatures due to the residues but the temperature of the residues itself could suppress germination. Teasdale and Mohler (1993) recoded residue temperatures of 41°C when the air temperature was 37°C. Changes in the soil temperature may enhance mineralization rates, thereby influencing nutrient availability (Facelli & Pickett 1991).Plant litter on the soil surface may retain some rain water, depending on the litter characteristics (Facelli & Pickett 1991), thereby limiting the amount of water available for germination. During dry periods soil moisture under the residues could be higher creating favourable conditions for germination. However, saturated conditions could reduce germination. C. album and S. viridis establishment was reduced by soil moistures above field capacity under hairy vetch residues (Teasdale 1993).The residues on the soil surface may obstruct seedling roots reaching the soil thereby reducing the growht of seeds and sprouts. Seedlings emerging from beneath the residues need to devote more energy penetrating it, leading to higher seedling mortalities. Small seeded species are more sensitive to covering, especially at the cotyledon stage. Once the stored resources of the seed are depleted no energy is available for growth (Baerveldt & Ascard 1999; Liebman & Davis 2000). The degree of weed control provided by the residues is likely to beinfluenced by the weed species and growth stage, the thickness of soil cover and the soil type.4.2 Weed suppression due to chemical interferenceThe allelopathic effects of cover crops on weed growth is the primary means of chemical interference and have been documented (Weston & Duke 2003). Plants interfere directly and indirectly with their neighbours, with a subsequent reduction in growth in any one or both of them as a consequence. Direct effects are attributed to competition and allelopathy, while indirect effects are attributed to changes in the growth environment due to physical effects and the presence of pests and diseases (Hoffman et al., 1996). With competition, growth factors are diminished, while with allelopathy, chemical compounds that are released into the environment affect plant growth (Khanh et al., 2005).4.2.1 Allelopathy researchThe root exudation and leaching of allelochemicals from a range of crops employed as cover-, smother-, companion- or intercrops form the basis of a weed management strategy involving allelopathy (Belz 2004; Khanh et al., 2005). However, the discipline of allelopathy has had its share of controversy, in part due to the following limitations: (a) complex research methodology is required for distinguishing between allelopathy and competition (Belz 2004), (b) the widely held assumption that all chemicals extracted from plants would exhibit allelopathic characteristics, and (c) the assumption that the mere presence of allelochemicals in plant tissue presents strong evidence for allelopathy (Inderjit & Callaway 2003).In the past, to prove that allelopathy was the cause of plant growth inhibition, unrealistic bioassays using leachates or extracts of plant parts in artificial conditions have been used (Foy & Inderjit 2001; Olofsdotter et al., 2002). Bioassays are important in the study and demonstration of allelopathy. Therefore, in order that experiments produce more convincing evidence for the existence and function of allelochemicals they should meet the following criteria: (a) showing allelochemicals being released from the donor plant and arrives infunctional concentrations under natural conditions at the receiver plant, (b) determination of the fate and persistence of allelochemicals in soil, (c) elucidation of the uptake mechanism of the receiver plant and its subsequent response (Blum 1999; Inderjit & Callaway 2003). To discover whether or not these subunits work together, a field study is necessary (Inderjit & Weston 2000; Khanh et al., 2005), but the evaluation of the contribution of each phenomenon to the overall effect in a field situation is difficult and therefore selection of allelopathic cover crop plants under field conditions is not an option (Foy & Inderjit 2001; Olofsdotter et al., 2002). In evaluating the ability of rice to control weed growth, research was focused on bioassays and field work that led to a correlation between growth inhibition and allelochemical release, which formed the basis of a subsequent international breeding programme for developing competitive rice cultivars (Olofsdotter 2001).4.2.2 AllelochemicalsAll plants synthesize secondary metabolites which are generally considered not important for primary metabolic processes essential for a plant’s survival. These metabolites represent a vast number of biologically active compounds, of which some are allelopathic and are referred to as allelochemicals. The allelopathic effect on plants is often the result of a combination of these chemicals released together, as individual compounds are often present in concentrations below their inhibition thresholds (An et al., 1998; Inderjit & Nayyar 2002).Allelopathic plants do not develop in isolation and environmental conditions influencing plant growth will directly affect allelochemical production and expression. The extent of their phytotoxicity depends on soil characteristics, abiotic and biotic factors, the donor and target plant species and cultivars used (Inderjit & Nayyar 2002).Adsorption, desorption and degradation of allelochemicals in soil are just as common a phenomena as with herbicides, and therefore, soil texture, organic andinorganic matter, moisture and micro-organisms as well as allelochemical solubility in water will affect their phytotoxic activity in the soil (Inderjit et al., 2001; Kobayashi 2004). A recent example of this is the abiotic and biotic variables that degraded the allelochemical parthenin released from the alien invader plant Parthenium hysterophorus (Parthenium), causing it to have short but variable half-lives in soil, depending on temperature, moisture and microbial activity (Belz et al., 2009). Soil micro-organisms can use allelochemicals as a food source and if allelochemicals are released, the micro-organism population can increase in response. Plant growth inhibition can be the result not only of the allelochemicals present but also because the micro-organisms can transform these compounds to new chemicals of lower or higher bioactivity. In addition, microbes can immobilize nutrients, with subsequent reduction in plant growth (Schmidt & Ley 1999).The abiotic factors water and nutrient content, temperature and applied herbicides have a significant influence on the availability of allelochemicals. In a review by Tang et al. (1995) various examples were given in which stress factors caused an elevation in allelochemicals. Gershenzon (1984) came to the conclusion that the accumulation of secondary metabolites under stress conditions must be an adaptive response to conditions under which the function of these compounds becomes important. Einhellig (1987) showed how certain herbicides synergize or supplement the activity of allelochemicals, which can have implications for conservation tillage as it is dependent on herbicide use. The fate of allelochemicals under stress cannot be generalized. The availability of growth resources for donor and target plants can be influenced by the presence of allelochemicals. Donor plants may be less influenced due to their adaptation to the stress, while target plants could lack this ability. Damage is therefore caused by abiotic stress or allelochemicals, or by both (Inderjit & Nayyar 2002).Choosing the cover crop species and cultivar would also have an impact on the allelopathic effect produced on weed species (Weston & Duke 2003). Differences in their ability to suppress weed growth were reported for, among others, stooling。
