| Abstract: | The effect of head-fertilizer dressed at various ages of leaves on the growth of rice plant, and the NAR, dry matter accumulation, numrber of flowers, factors that constitute the yield and seed yield was studiel by using Shanyou 63.Results indicated that the yield of the treatment in which the urea 6 kg/mu divided into three parts egually dressed at backwards 1st, 2nd and 3th leaf was higher than thattreatments in which the urea 6kg/mu dressed once a time at backwards 1st, 2nd, 3th, 4th or 5th leaf. |
