Abstract:
A field experiment was conducted for two consecutive cropping seasons (2014-2015) on farmers’ fields in Welmera district of Oromiya Regional State in Ethiopia. The objective of this study was to increase the overall performance of cropping systems by providing economically optimum nutrients to food barley production while minimizing nutrient losses from the field. The treatments included five Nitrogen rates and four phosphorus rates. Nitrogen was applied in the form of urea (46% N) at a rate of 0, 23, 46, 69, 92k g N /ha and phosphorus in the form of triple superphosphate (45% P2O5) at 0, 10, 20, 30 kg P /ha. The treatments were laid out in a randomized complete blocks design with three replications. The results show that the highest grain yield (4858 kg/ha) was obtained at the rate of 92 kg N/ha. Similarly, with phosphorus the highest yield (4925.8 kg/ha) was recorded at the rate of 30 kg P/ha, while the maximum value cost ratio of 9.1 and 10.9 were obtained when 69 kg N/ha and 10 kg P/ha were applied, respectively. Balanced nutrition and fertilization is essential for soil fertility and a prerequisite for achieving adequate yields of food barley and quality of production
