Abstract : A field experiment was conducted at Pawe Agricultural Research Center during the main rainy season of 2018 to evaluate the effects of nitrogen and phosphorus fertilizer rates on phenology and seed yield of okra. The experiment was laid out in randomized complete block design with three replications in factorial arrangement. Urea and triple superphosphate (TSP) used as a source of nitrogen and phosphorus, respectively.Plant height, leaf number per plant, primary branch number per plant and 50% flowering date were significantly affected by nitrogen and phosphorus fertilizer applications. Date of 50% emergence dry pod length and width were not significantly affected by nitrogen and phosphorus fertilizer rates. Significant responses were also observed in seed yield and related traits of okra due to nitrogen and phosphorus fertilizer application.Maximum pod number per plant (20 and 19.67) were recorded from treatment received at the rate of 0 and 75 and 50 and 37.5 kg/ha N and P, respectively. Similarly maximum number of seeds per pod (93.47) were recorded from N and P treatment at the rate of 0 with 112.5 kg/ha. The highest 1000 seed weight (80.83 gm) were obtained from the combinations of N and P at the rate of 50 with 75 kg/ha. Yield is the result of these mentioned traits and significantly maximum yield (659.01 kg/ha) were recorded from N and P treatments at the rate of 0 with 75 kg/ha. It is possible to conclude that application of N and P at the rate of 0 with 75 kg/ha gives economical optimum amount of seed yield of okra in the study area.
