In the English writing class, the instructor and subjects in EG assessed their revised papers according to English writing assessing standards made together by the instructor and subjects. The instructor would give the delayed assessing to the papers submitted by subjects in EG after the class because of the limited class time. This research has been embedded in the theoretical discourse of world system theory commonly known as world systems analysis. The world system approach was developed by Immanuel Wallerstein in 1970s and 1980s. His three volume work “The modern world system” , and number of essays  were the major contribution in developing the theory. The other contributors of world system theory are Samir Amin , Cardoso and Falleto , Santos , Rodney , and Andre Gunder Frank . Wallerstein has divided the capitalist system the world into different zones on the basis of their wealth and size which keeps on competing with one another for wealth and power. These zones are “core”, “semi-peripheral” and “peripheral” regions. The core region includes the most powerful and technologically advanced countries. Periphery includes poorer and technologically less advanced countries. Economies of these countries mostly based upon the raw material export. The semi-periphery includes the countries which are poorer to the core but have the potential to take core status if the conditions suit them. Core countries earn very high profits from international trade. They exchange manufactured products for raw materials mainly from peripheral countries and to some extent from the semi-peripheral countries. The core countries are becoming richer and richer at the cost of the peripheral economies. In general this theory says that the world’s capitalist economies determine the rout for development of the large part of the world’s population in their own favour. Its geographic expansion has changed political systems as well as the labour conditions wherever it could penetrate. Functions of the world economy have created big differences and inequalities among the economies of different countries. The relationship between the core, peripheral and semi-peripheral countries are also relative inconstant. Technological development brings positive changes all over the world. Some impulsive changes are brought in peripheral or semi-peripheral countries, but the core countries get the most advantage.

Wallerstein, however, after the analysis of history of the capitalist world system firmly concluded that this development has created inequality and disparities in economic and social sectors of different countries rather than bringing prosperity all over the world. Most of the world system theorists have analyze its implementation at macro level. The exploitative relation between core and periphery has been studied at state level. In this research this model will be put on test at micro level to confirm,mobile grow system revise or drastically change the reasoning built into this. Its impact would be observed on village economy. The researchers would try to examine how this development of underdevelopment influences the masses at grass root level. Arnove  has emphasized the need of further research at micro level. According to 1998 census the total area of Zandra is 1229 acres; out of which 367 acres are under apple orchard. In 1986 the area under apple orchard was 227 acres. Reportedly, special efforts were made by the villagers at individual level to expand the area under fruit orchards. Apple is cultivated in all 367 acres of land. Some farmers have also planted other fruit trees in the same orchards i.e cherry, apricot, peaches and almonds etc. The ratio between apple and other fruits is 95%:5% respectively. Since the middle of 20th century, the village economy has undergone a transition. Initially it was based on horticulture only with apple as the main source of income, but over the years the population has outgrown the farming resources. Landholdings have reduced and hence the majority, apart from providing services to the orchards, during the season, has taken up other nonagricultural activities like different businesses and employment in public and private sector to earn additional income. In order to further supplement domestic income, the women folk have also started producing home based handicrafts like crochet work, embroidery, stitching etc. besides the household chores. Women are also working mostly as teachers and some others as lady health workers , lady health visitors  lady doctors etc. but they are very few in numbers. In spite of these changes apple is still the main source of income for majority of the people in the village. The natives mostly depend upon the income from the orchards. Apple trees bear fruit only once a year during April-August. Thus, the people, who solely depend on the apple production can only earn once a year. The big landholders can easily spend whole year on the orchard income. An average annual income per acre is Rs. 300,000 to 400,000. The steps involved in horticulture are production, plucking, packing and sale. In Zandra, there are three types of land i.e land prepared by flood water, plain land and stony land. Plain land is artificially prepared by leveling the stony land with the help of bulldozer and filling it up with mud brought from the dam. After leveling trees are planted in March or December because more water is available as the schedule of Karez is suspended and anybody can use it. For better production of fruit, grafting and budding of trees is done in two different ways which include “Tee Budding” and “Ring Budding”. Fertilizers and insecticides are also used whenever needed.

An apple tree takes about seven years to grow, but their production remains low. The trees ageing ten to fifteen years give maximum and a very high quality production. After that the quality starts deteriorating because the trees get thicker and the proper amount of sunlight does not reach the fruit and it starts losing its colour. Since the start of apple economy 9 different kinds of apple were grown in the orchards, which includes Kala Kolu , Sabaz Kolu , Lal Kolu, Kashmiri, Mashadi, Ameri, Kandhari, American and Fransi. Kala Kolu is considered to be the best and dearest of all apples. It is also called Golden apple. Sabaz Kolu has a longer life. It can be stored for longer durations. As far as the taste is concerned, both of these are considered as the best. Kashmiri, Mashadi, Ameri and Kandhari come in the next order of taste and quality. American, Fransi and Lal Kolu are small in size and sour in taste, and are used for making jams and juices only. But now from the last 20 years, the people have gradually switched over to two kinds of apple-Kala Kolu and Gaja, because of their great export value and local market demand. Both of these types have higher rates and bring them more profit. This shows that desire for more money is forcing them to abandon their traditions. This traditional society is gradually changing into a more profit oriented society. During the last couple of decades technology has played a pivotal role in the development of new cultivation methodologies. Beasts of burden such as donkeys and bulls are no longer used for cultivation; instead tractors and bulldozers are used. Modern spraying machines for insecticide, mobile vertical rack trucks for transportation and chemical fertilizers are commonly used. Office of Agriculture Department in the village creates awareness and facilitates the natives to use modern technology. Improved road network has made market access easier. Until 2002 horticulture production was mainly depending on Karez water. A small area was irrigated through tractorpowered wells. In 2002 electric tube-wells were introduced in the area. These tube-wells are providing sufficient amount of water and fulfilling most of their irrigational needs. The horticulturalists of the village could be divided into three categories which include owner cultivators who work in their fields and market their product themselves. Majority of the medium and small landholders falls under this category. Exporters normally approach the owners themselves. The direct access of the exporters to the farms is a new phenomenon, which has become popular during two decades. Now more than 40% of the total apple production is sold to them. The second category is owner non-cultivators. Big as well as small landholders who do not work in their orchards fall under this category. Non-owners cultivators are the third category which includes landless and the small landholders. They hire the orchard in the beginning under a contract, work there and in the end share half of the produce with the owner. In the beginning of 20th century people of the village were nomads, apple economy brought them to permanent settlements.

Subsistence economy has changed into market economy. Farmers started growing fruits and crops to sell in the market. Their reliance on consumer products increased. Shift from subsistence economy to market economy supports the industry as the raw materials, which includes livestock and farm production are sold in the market to earn money and for personal consumption they are bought from the market produced or processed by the industry. So the ultimate beneficiary of this change remains the industrialist of core countries for being producer of all these products. Since the middle of 20th century, the village economy was based on horticulture with apple as the main source of income, but now they are involved in different businesses and employment in public and private sector to earn additional income. In order to further supplement domestic income, the women have started working. Some of them have started producing home based handicrafts. Moving from horticulture economy to businesses and employments in public and private sector to earn additional income also benefits the industry as it finds cheap labour. Supplementary domestic income by the women folk through handicrafts helps to maintain low wage rates. Joint families are breaking into nuclear families, which has changed the bigger land holding patterns to the small pieces of land. When joint families break into nuclear families it normally results into urban migration where the majority of the adults work for the industry and their dependence upon the consumer products also increases. In the field of horticulture use of technology, modern techniques, transportation, pesticides and chemical fertilizers is clearly visible and it has grown during the last three decades. All these items are imported from the core countries sometimes in shape of finished products and sometimes in shape of instillations, industrial supplies and fabricated parts. Use of pesticides and chemical fertilizers gives rise to health problems due to which medical bill increases and the pharmaceutical industry of the core countries gets benefit. The transfer of wealth by exploiting periphery and semi-periphery by core countries which encourages rapid scientific development so that Western medicine and other scientific institutions could surpass underdeveloped countries of the world. The low profit farm products are no more cultivated. Majority of the natives has switched over to the types having great export value, local market demand and high profit. The market is in transition from local market to the export. Before 1980 s total production was consumed at local markets but now more than 40% of the apple is sold to the exporters.

Increase in the export of farm products supports Wallerstein argument where he says that world is becoming a single economic unit through exchange and trade with a vast diversity in division of labour among the countries. In the end the researcher is in full agreement with the views of world system theorists who have been working in the field of capitalist world economy. The argument developed by Wallerstein, Samir Amin, Cardoso and Falleto, Santos, Rodney, and Andre Gunder Frank seems valid. So in the light of empirical data world system theory is found valid and accepted. Hydroponic systems have been used as one of the standard methods for plant biology research and for the commercial production of vegetables such as tomatoes. In addition, it has served to study the responses of plants to biotic and abiotic stress.Abiotic stress factors, such as salinity, affect the uniformity and nutrition of the tomato. Root pretreatment with hydrogen sulfide  protects strawberry plants against salt stress. The exposure of Populus x capeskins hydroponically to Cd and H2O2 showed that the first agent inhibited the antioxidant enzymes. The peroxide caused the accumulation of GSH and the loss of ascorbate .
