1985
Oh W.K. | Kim S.B.
The effect of potash applied with different sources of nitrogen was experimented in pot 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. Ammonium nitrate increased the yield of Chinese cabbage more than urea did, and the effect of yield increased by ammonium nitrate was greater in the fall cultivation than in the spring.
