Nutrient deficiency and absence of locally adapted varieties are the problems in reduction of wheat production in Ethiopia. Hence, experiment was conducted to assess the effect of blended NPS fertilizer on bread wheat varieties (Triticum aestivum L) and to determine the economically feasible fertilizer rate for production. The results revealed that days to heading, maturity, plant height, number of effective tillers per 0.5m length, spike length, number of grains per spike, thousand grain weight, above round biomass, harvest index and yield were significantly influenced by both factors, while plant height and harvest index are significantly influenced by interaction effect. The highest (6449 kg ha-1) and lowest (3160 kg ha-1) grain yield were obtained from150 kg ha-1 NPS and zero NPS, respectively. The highest and the lowest grain yield obtained from Qulqulu (5322 kg ha-1) and Shorima (4812kg ha-1), respectively. The partial budget analysis indicated that the highest net benefit of 94223.04 ETB ha-1 with a marginal rate of return 1141.33% obtained by planting of Qulqulu variety with 150 kg ha-1blended NPS fertilizer. Therefore, it can be concluded that the application of 150 kg NPS ha-1 and the growing of Qulqulu variety could be better choice of the farmers of in the study area.
