To determine which method is appropriate, we conducted two methods in two different net house, after that we followed the tomato growth, weed situation, plant pathogens and Compare the yields obtained between two net houses from which the conclusions are derived. After the implementation period, observed and rely on the data obtained. We conducted the analysis and evaluation of the two soil treatments that resulted is soil treatment using nylon overlay is better. Although the soil treatment method using nylon cover provides greater efficiency, there are also certain constraints such as higher costs, more time spent on soil treatment that cause crop delay, For workers also higher ... so, depending on the purpose and ability of the farmers that choose the method accordingly.

More than half of the land area is desert, and the climate and lack of water resources not favor farming The soil conditions here are mostly sandy soil Conditions in the Ramat Negev climate Sandy soil Extreme temp, between day and night, between High radiation High evapotranspiration Water salinity Low humidity Poor nutrients winter and summer What is solution? Control elements inside Prevent disease and pest greenhouse Avoid the impact of weather Increase water and fetilizer use efficiency basis factors in good agricultural production human - Provide nutrients and minerals water variety Cultivating medium of plants, the habitat of many species of beneficial microorganisms - Habitat and farming of human fertilizer soil Why soil treatment is extreme important? Importance of soil treatment before planting[1] Convenient and easier for planting and caring tomato Create better living Increase porous soil, improve some soil properties conditions for many Increase in soil types of soil aeration Destroy and prevent some pathogens of plants microbiology SOIL TREATMENT TECHNOLOGY BEFORE PLANTING IS VERY NECESSARY To show the importance of soil treatment before planting of tomato at Yoav Katsir’s farm, we progressed the effect comparison between two below soil treatment methods: One method is soil treatment with plastic cover, expose soil under sunlight, incubating soil with plastic Other method is soil treatment don’t use plastic cover, don’t expose also incubating 10 Observing method Observation is way of gathering data by watching behavior, events, or noting physical characteristics in their natural setting [3] In our report we looked at the development of tomatoes in two farms in order to find the difference between the two farms in terms of growth rate, disease status, weeds as well as the loss of water and fertilizer This method takes a lot of time because it must monitor the development of the tomato from early planting to harvest 21 Data collection method Data collection is the process of gathering and measuring information on targeted variables in an established systematic fashion, which then enables one to answer relevant questions and evaluate outcomes [4] The goal for all data collection is to capture quality evidence that then translates to rich data analysis and allows the building of a convincing and credible answer to questions that have been posed [4] In this report we collect data by recording the harvested yield, collecting observable data, photographing, asking the farmer for the required data 22 Data analysis method Analysis of data, is a process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, suggesting conclusions, and supporting decision-making [5] In this report we have made calculations based on the data collected, then there are comparisons and evaluations to make the final conclusions 23 Results The difference comparison table between greenhouse Nylon cover method Non-nylon cover method Cost High Low Yield High Low Have a lot of new weeds and tomato plants from Diseases and weeds Have not pathogen from previous season Irrigation less more Time to month to week previous season 24 Cost The soil treatment method with nylon cover need material is nylon, so the cost will be more than other method In greenhouse that was not incubated by nylon had a lot of weeds and new tomatoes from previous season, so we need the cost for workers to take them out We need 18 workers worked in hours to take them out and to times per season The nylon cover method need about 40 workers per day for a farm, the other method only need 20 workers per day, so the cost for workers will be less than nylon cover method 25 Cost In greenhouse that was not incubated by nylon had a lot of water spread out of seedbed cause waste water and nutrients 26 Diseases and weeds Greenhouse with nylon cover tomatoes grow very well and fungal diseases are not The tomatoes in greenhouse that did not cover by nylon are well developed at beginning, but after about months the weeds and fungal diseases begin to occur a lot weeds disease 27 Yield According to the results obtained, with the greenhouse had nylon cover we harvested about 10 tones per weeks and the greenhouse was not cover by nylon we harvested about 8.5 tones per weeks 28 Discussion When the nylon cover on the ground causes high temperatures in the soil combined with long periods of time to destroy the virus as well as the fungal pathogen, the weeds and tomato seeds remain in the previous crop The treatment method does not cover the nylon to help farmers active time for the next season, it is possible to carry out new crop immediately after clearing the previous season so it is easy to grow tomatoes between farms, The tomato supply is always guaranteed, which saves labor costs (worker, raw materials, and time), but it is highly pathogenic (bacteria, viruses, fungi) in the process of planting, the cost of nutrients, the water from the plants not attract much of this substance and loss of farm landscape 29 The soil treatment method has nylon cover which makes the soil more likely to rest and lose less elements in the soil (Fe, Ca ) than the non-nylon cover method The pathogen is minimized so it is easy to control and kill when disease occurs, the plant can absorb the maximum amount of soil nutrients supplied by the farmers, these factors bring about economic efficiency optimal but the method also has certain limitations such as high production costs, farmers have to plan ahead The ultimate goal of production is still profit, so when comparing the advantages and disadvantages of the two methods we still see that the soil treatment method with nylon cover is more economical and helps the soil more stable 30 During the report, there were some deficiencies in the implementation process, such as not being able to analyze the amount of water the plants will absorb on the farm as well At the stage of plant observation there are still many factors that we can not exclude that may affect the results of the report However, we have eliminated to the maximum extent the external factors that affect the results of the report 31 In spite of the efforts, limitations in terms of time, knowledge and experience, there are still shortcomings in the report, so that a truly complete report will require additional research, for example : Study the effectiveness of using compost Find out the exact cost for each method for a more specific comparison Calculate the amount of water needed for the plant to determine the amount of extra water consumed in the nylon-free method 32 Acknowledgments To make this report we sincerely thank the school and teachers for their enthusiasm Next, we would like to thank the farm owners and farmers on the farm for facilitating the completion of our report finally thank friends for their enthusiastic support during the process of report 33 references [1]:http://www.wikihow.com/Grow-Tomatoes-in-a-Greenhouse [2]:
