Yield Response of Barley (Hordeum Vulgare L.) to NPS and Urea Fertilizers Rates at Alicho Wuriro Highland, Southern Ethiopia

Barley can be cultivated and gives better yields in a large number of environmental conditions, except in extreme high rainfall areas which limit the yields. The experiment was conducted at Alicho wuriro highland with the objective of determining the effect of determining the optimum rate of NPS and urea fertilizers rates on yield of food barley in 2016 and 2017. The soil is clay loam with pH 4.8, 0.308% N, 3.2 mg/L P, 11.2 mg/L K and 2.4% OC. Two factors, NPS rates (0, 50, 100, 150 and 200 kg/ha) and urea (0, 50 and 100 kg/ha) were combined in 5x3 factorial arrangements of RCBD in three replications. The grain yield was significantly affected due to NPS and urea fertilizers rates. The highest significant economic yield was obtained at the combination of 200 kg/ha NPS and 100 kg/ha urea as compared to other rates in both years. Generally, applications of 200 kg/ha NPS and 100 kg/ha is advised around Alicho wuriro highland. Keywords: Food barley, NPS, urea, grain yiel
