A field experiment was conducted to evaluate the efficacy of foliar sprays of different organic fertilizers on the growth and yield of okra (Abelmoschus esculentus L.) at the Institute of Agriculture and Animal Science, Rupandehi, Nepal, from April to July 2022. “Arka Anamika” variety of okra was used. With five treatments and four replications, the experiment was arranged in a randomized complete block design (RCBD). The treatments used were control, fish amino acid (FAA), moringa fermented plant juice (FPJ), Ipil-Ipil fermented plant juice, and vermicompost tea. The data collected after the application of these treatments were analyzed using R-Studio version 4.2.1. Among the treatments used, fish amino acid produced a significantly higher yield (14.26 tons/hectare) than moringa FPJ (12.82 tons/hectare), Ipil-Ipil FPJ (12.44 tons/hectare), vermicompost tea (11.67 tons/hectare), and control (11.16 tons/hectare). The result also revealed that different treatments have a significant effect on plant height, number of leaves, number of branches, and number of buds, with a 0.05 level of significance. The maximum number of leaves (37.97), number of branches (5.88), pod length (15.33 cm), bud number (12.70), and fruit weight (18.87 grams) were observed in FAA, while control showed the least among all treatments. Therefore, the result indicated that fish amino acid is a more potential organic fertilizer than moringa FPJ, Ipil-Ipil FPJ, and vermicompost tea for okra production.
