Abstract
The effect of potash applied with different sources of nitrogen was experimented in pot soil culture on chinese cabbage (Brassica Pekinensis Rupr, Var. Fall 1984: Sammi Garak, Spring 1985: Jungang Summer lab.) in the fall, 1984 and in the spring, 1985. Results obtained are as follows; 1. Ammonium nitrate increased the yield of chinese cabbage more than urea did, and the effect of yield increase by ammonium nitrate was greater in the fall cultivation than in the spring. 2. The yield of chinese cabbage was positively correlated with the contents of K in the first (May 17, 1985) and second (June 9, 1985) thined cabbages (dry matter). It was also positively correlated with
질소의 비종에 따른 배추 ('84 가을 삼미가락, '85 봄, 여름배추)에 대한 칼리비료의 효과를 폿트에서 재배 시험한 결과는 다음과 같다. 1. 질산암모늄은 요소보다 배추의 생육량을 늘였는데 그 증수효과는 봄보다 가을에 컸다. 2. 배추의 수량은 1차(5월 17일) 및 2차 솎음 (6월 9일) 배추의 K함량 (건물) 및 1 차 솎음 배추의
