My area is famous for farming or farming because in my area farmers can produce vegetables reached 43,673 tons in in 2010 or about 35.80% of the total vegetable yield . Common vegetable cultivation found in my area is a system conventional agriculture. System Conventional is an agricultural system aimed at to obtain maximum agricultural production by utilizing modern technology such as high doses of synthetic chemical fertilizers and pesticides with no or little input of organic fertilizer . Application conventional systems have been carried out in this region since 1980s.Conventional vegetable farming is one of the agricultural system applications that has the potential to reduce the level of pushing destruction of soil structure, decreased fertility soil, and loss of fertilizers and other chemicals due to erosion and leaching. In the long run these impacts can reduce the quality and soil productivity due to soil degradation. Increased consumer awareness of the product safe vegetables free of chemical residues and friendly the environment has driven the demand for the product organic vegetables increase with more price expensive. Some vegetable farmers have turned to organic farming system. Organic farming is agricultural systems that use natural inputs to increase soil fertility and not use of chemical fertilizers and pesticides. This farming system provides a variety of possibilities for mitigating the negative impacts of conventional agriculture so that it plays a significant role in broad for sustainable farming systems. organic farming system brings many advantages for the agricultural system because can improve soil quality and safety food, as well as increasing the C-organic content in the ground. However, this system has not widely adopted by farmers due to a decrease very significant results, reaching 50 percent in the early phase of the transition from conventional agriculture into an organic system. The decrease was due to by drastic reductions in chemical fertilizers and synthetic pesticides that trigger nutrient limitations especially nitrogen, pest attack, and stress weed. This study aims to determine combination of manure and chemical (NPK) give different vegetable yields with conventional agriculture in order to determine the transition strategy from agriculture conventional to organic systems. The world of agriculture needs changes from time to time to increase abundant production yields to keep the soil fertile is a positive review to have the opportunity to have higher yields continuously over a long period of time. The way people in my area get abundant yields is conventional farming.
