Effects of Organic Materials Application on Growth of Peanut Plant

유기물(有機物) 시용(施用)이 땅콩 생육(生育)에 미치는 영향(影響)

This experiment was conducted to find out the effects of organic materials application on the growth of peanut, yield and chemical properties in mature field and newly reclaimed upland soil. The result can be summarized as follow. 1. Application of rice straw and rice hull increased the yield of peanut in mature field and compost plot was more yield than any other plot in newly reclaimed upland soil. 2. Rice straw and rice hull plot was heavier the weight of needles per plant than compost plot in newly reclaimed soil. 3. There was high correlation between soil O.M. at flowering stage and yield in newly reclaimed upland soil but was not significant in mature field. 4. Contents of soil O.M. did not change in mature field however this was increased tendency in newly reclaimed upland soil.

숙전(熟田)과 신야산개간지(新野山開懇地) 토양(土壤)에서 유기물(有機物) 종류별(種類別) 시용(施用)이 땅콩의 생육(生育)과 수량(收量) 그리고 토양화학성(土壤化學性)에 미치는 효과(效果)를 검토(檢討)한 결과(結果)는 다음과 같다. 1. 숙전(熟田)에서는 신선(新鮮)한 유기물(有機物)인 볏짚, 왕겨 시용이 수량(收量)을 증가(增加)시켰으나 야산개간지(野山開墾地)에서는 퇴비(堆肥) 시용(施用)이 수량(收量)을 증가(增加)시켰다. 2. 야산개간전(野山開墾田)에서 C/N율(率)이 높은 볏짚, 왕겨 시용구(施用區)가 근류(根瘤) 착생량(着生量)이 많았다. 3. 유기물(有機物) 함량(含量)이 많을수록 야산개간전(野山開墾田)에서 수량(收量)이 증가(增加)되었으나 숙전(熟田)은 경향이 없었다. 4. 시험후(試驗後) 토양중(土壤中) 유기물(有機物) 함량(含量)은 숙전(熟田)에서는 변화(變化)가 없었으나 야산개간전(野山開墾田)은 약간 증가(增加)되는 경향(傾向)이었다.
