Abstract: This study was determining an optimum rate of Nitrogen (N) and phosphorus (P) fertilizer rates for maximum maize production. The experiment had two factor: levels of N (0, 46, 92, and 138, kg/ ha-1) and levels of P (0, 23, 46, and 69kg ha1 ) arranged in Randomized Complete Block Design (RCBD) with three replications. Agronomic traits siliking, tasseling, LA, LAI, Eear, length, plant height, above ground biomass, TSW, Grain yield highly significantly varied due to Nitrogen, phosphorous and their interaction. The highest grain yield (5840 kg/ ha-1) and highest harvest index (42.87%) were obtained from application of 138 kg Nitrogen ha-1 with 46 kg/ ha-1 phosphorous. The results of the economic analysis showed that the net benefit (211065 birr) and maximum net return (1886 %) was obtained due to the application of 138 kg Nitrogen ha-1with 46 kg phosphorous ha-1. The maximum grain yield (5840. 67 kg/ha-1) was obtained due to highest level of N (138 kg N/ha) and 46 kg P/ha. the performance of the study depicted that an application of 138 kg Nitrogen ha1 with 46 kg phosphorous ha1 enhanced yield of maize with acceptable economic benefit. However, the experiment was carried out only in one location for one cropping season, so further studies at different locations for several seasons is needed to recommend agronomical optimum and economically feasible levels of Nitrogen and phosphorous fertilization study area.
