The yields of cabbage, radish and sweet corn at fall crop season were 10.8-29.1 percent, 12.3-15.5 percent, and 5.5-6.9 percent lower in organic farming than those grown under the conventional farming, respectively. However, at the spring crop season, the yields of organically grown sweet corn and vegetable soybean as well as phaseolus bean which were planted after the harvest of rice were much higher than those grown under the conventional farming. The yield of organic summer rice was significantly less as compared to conventional farming. Pests and insects epidemics of various crops under the organic farming were more severe than conventional farming with the exception of vegetables. Nevertheless, the infestation under the organic farming was within the controllable level. Weeds were 3-4 times serious in organic farming. Generally, the appearance of organic products was less attractive. However, the taste of cabbage, radish, vegetable soybean, sweet corn and rice was better than those produced by the conventional farming. It was observed that the input for organic products was 2-4.2 times higher than those for conventional farming in terms of costs of organic fertilizer and labor in both rotation systems, resulted to lower and negative net income for organic farming
