The present study examined how fertilizer affects okra's economic productivity. The experiment was replicated three times using a randomized complete block design (RCBD). The treatments included two rates of inorganic fertilizers (100kg/ha NPK and 200kg/ha NPK), three rates of organic fertilizers (poultry manure-Pm) (5, 7.5, and 10 t/ha), and one control (no fertilizer). Analysis of variance was performed using collected data. At 5% probability, significant means were compared with the least significant difference. Results demonstrated significant okra growth and production differences. In both cropping seasons, 10 t/ha Pm increased okra fruit yield to 15.15 and 15.20 t/ha and fruit number to 22.94 and 22.85. In 2021 and 2022 cropping seasons, 7.5t/ha of Poultry manure (PM) yielded 14.81 and 14.91 t/ha fruits, whereas 200kg/ha yielded 12.98 and 13.40 t/ha. The control treatment produced the lowest fruit yield, 3.55 and 3.54 t/ha in both cropping seasons. The treatment of 7.5t/ha PM had the highest economic returns to management; N 1,068,350 and N 1,273,700 with a cost-benefit ratio of 3.09 and 3.47, respectively while the least; N 26,550 and N 65,000 with 0.09 and 0.2 cost-benefit ratio, respectively was recorded in the control treatment. Treatment of 7.5t/ha was recommended for higher yield and economic production of okra in Uyo, southeastern Nigeria.
