Inorganic fertilizers are important tools to overcome soil fertility problems and are also responsible for a large part of the food production increases. The study was aimed to determine the optimum level of NPS-B by supplementing N from urea rates for maximum yield of tef production and to determine the economically optimum level of NPS-B by supplementing N from urea fertilizer. The treatments were: (100 kg ha-1 NPSB + 100 kg ha-1 Urea), (150 kg ha-1 NPSB + 100 kg ha-1 Urea), (200 kg ha-1 NPSB + 100 kg ha-1 Urea), (150 kg ha-1 NPSB + 200 kg ha-1 Urea), (150 kg ha-1 NPSB + 200 kg ha-1 Urea), (150 kg ha-1 NPSB + 200 kg ha-1 Urea), (200 kg ha-1 NPSB + 200 kg ha-1 Urea), (250 kg ha-1 NPBS + 200 kg ha-1 Urea), (100 kg ha-1 NPSB + 300 kg ha-1 Urea), (150 kg ha-1 NPSB + 300 kg ha-1 Urea), (200 kg ha-1 NPSB + 300 kg ha-1 Urea), (250 kg ha-1 NPSB + 300 kg ha-1 Urea), control and R-NP (60N 35 P2O5). The treatments were arranged in a randomized complete block design and replicated three times. The maximum biomass yield (13.2 tone ha-1), grain yield (2.6 tone ha-1) was obtained from the application of 200 kg ha-1 of NPS-B blended fertilizer with 100 kg ha-1 Urea. The economic analysis revealed that the highest net benefit of 93885.9 ETB ha-1 with a marginal rate of return (MRR%) of 143.8% was obtained in response to the application of 200 kg ha-1 of NPS-B blended with 100 kg ha-1 of Urea. However, the lowest net benefit was obtained from an unfertilized or control plot. Therefore, applications of 200 kg ha-1 NPSB of blended plus 100 kg ha-1 of urea are economically advisable for farmers in the Halaba districts southern, Ethiopia and areas with similar agro-ecological and soil types for better tef production.
