논 栽培 콩의 栽培條件에 따른 生長 分析

Abstract

To evaluate growth adaptation of the soybean in paddy field, five soybean cultivars were grown in Yeoncheon with two cultivating methods, level row and high ridge. Growth characters of the top plants, such as stem lengths, numbers of branches, diameters of stem,were higher under high ridge than under level row. However, the differences among the cultivars were bigger than those between the cultivation methods in each cultivar. Comparing the growth of top plants, dry matters in level row were higher than those in high ridge in V5 stage, however, via verses as growth progressed with significant differences among the cultivars. Roots were more developed under high ridge than those under level row during whole growth stages, such as V5, R2, and R5 stages. T/R ratio in level row was significantly higher than that in high ridge with significant differences among the cultivars.
