Abstract: In order to explore the effect of N, P and K fertilizer on the yield of brewing sorghum and to find the optimum fertilizer formula of N, P and K for high yield of sorghum, based on‘3414’test design, a field trial with sorghum variety‘Jinza No.23’was conducted to investigate the effects of different fertilizer formulas of N, P and K on agronomic characters and yield of sorghum in the experimental plot of the Industrial Crop Institute of Shanxi Academy of Agricultural Sciences, China. The results showed that the agronomic characters, ear grain weight and1000-grain weight of sorghum of different fertilizer treatments were higher than that of the control treatment, but there was no significant difference by variance analysis; on the basis of certain soil fertility, increasing fertilizer could obtain higher yield than no fertilizer; N and P fertilizer significantly increased the yield of sorghum grain, but with the increasing of N fertilizer, sorghum grain yield decreased significantly. Under the experimental condition, N fertilizer application amount of 96 kg/hm2, P2O5 fertilizer application amount of 76 kg/hm2, and K2O fertilizer application amount of 60 kg/hm2 were the reasonable formulas for high-yield, low-cost and high-income of sorghum.
