Effect of Continuous Application of Organic Farming Materials on the Soil Physicochemistry Property and Plant Growth, Yield and Components of Tomato

유기농 자재의 연용이 토양의 이화학적 성질과 토마토의 생육, 수량 및 체내성분에 미치는 영향

This study the effects of the application of organic farming materials on the soil Physicochemistry property and plant growth, yield and components of Tomato were compared with conventional culture. The results obtained from the experiment are summarized as follows : 1. The effect of soil chemical properties after application organic farming materials, The amounts of pH and O.M. in N, P, K treated plot were few of change, To the contrary, fermentation compost and microorganisms fermentation compost treated plot were some increase, Amount of $P_2$$O_{5}$, Ca and K increase in comparison with the N, P, K treated plot. 2. Changes of soil microbial after application organic farming materials, The number of bacteria, actinomycetes and fungi in N, P, K treated plot were appeared definite direction. to the contrary, The number of bacteria and actimycetes in fermentation compost and microorganisms fermentation compost treated plot showed the increased tendency, The number of fungi showed the decreased tendency. 3. Effect of organic farming materials application on the growth and yield of tomato was superior in order of microorganisms fermentation compost plot〉 chemical fertilizers plot〉 fermentation compost plot. especially, chicken manure ＋ microorganisms fermentation compost treated plot was the highest. 4. Effect of organic farming materials application on the components of tomato were not different.
