The drive for higher agricultural production without the balanced use of fertilizers created problems of soil fertility exhaustion. Inorganic fertilizers have been the important tools to overcome soil fertility problems and also responsible for a large part of the food production increases. The study was conducted at Bule, Gedio Ethiopia, and aimed to determine the optimum level of NPS-B and by supplementing N from urea rates for maximum yield of bread wheat production and to determine the economically optimum level of NPSB and by supplementing N from urea fertilizer. The treatments were: (100 kg ha-1 NPSB + 150 kg ha-1 Urea), (150 kg ha-1 NPSB+150 kg ha-1 Urea), (200 kg ha-1 NPS+150 kg ha-1 Urea), (250 kg ha-1 NPS+150 kg ha.. View more»
