Abstract

Soil fertility is one of the major production constraints in Ethiopia. The deficiency of nitrogen and phosphorus is the main factor that severely reduces the yield of sorghum. As a result, a field experiment was carried out at Omo Nada in 2015/2016 during the cropping season to evaluate the response of various levels of nitrogen (N) and phosphorus (P) fertilizer using sorghum. The treatments consisted of factorial combinations of four rates each of N (0, 23, 46, and 69 kg N ha^-1) and P (0, 11.5, 23, and 34.5 kg ha^-1 P₂O₅) laid down in a randomized complete block design (RCBD) with three replications. For data analysis, the correlation coefficient and ANOVA were used. The result showed that the yield and yield components of the sorghum crop were a highly significant response to the impacts of inorganic N-P fertilizer nutrients. Parameters such as plant height, head weight, grain yield, biomass yield, stover yield, and harvest index were statistically significantly different for nitrogen and phosphorus at different fertilizer rates. In addition, highly significant and positive correlations of grain yield with yield components were observed, especially for plant height (r=0.57**), head weight (r=0.85***), biomass yield (r=0.89***), and stover yield (r=0.75***). This result revealed that the maximum value of grain yield (3916.7 kg ha^-1) was obtained from 69/11.5 kg ha^-1 NP fertilizer, while the minimum value of grain yield (2286.2 kg ha^-1) was obtained from the control. Compared to the control treatment, the highest rate of N/P (69/11.5 kg ha^-1) increased sorghum grain yield by nearly 71.32%. It is concluded that nitrogen and phosphorus at the rates of 69 kg ha^-1 N and 11.5 kg ha^-1 P₂O₅ have the best performance in obtaining the maximum grain yield of the sorghum crop. Therefore, the application of 69/11.5 N P kg ha^-1 fertilizer rate was recommended for better sorghum production and economic return in Nitisols of Omo Nada district southwestern Ethiopia.
