A research was carried out to investigate the effect of different levels of NPK and vermicompost on growth and yield of okra Abelmoschus esculentus L. var. Khasi Kranti. The field experiment was conducted during kharif season of 2021 at central research farm, department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj. The soil of experimental area falls in order inceptisol and soil texture was sandy loam (sand 61.20%, silt 23.20%, clay 15.6%). This is a factorial combination of three levels of NPK and three levels of vermicompost which resulted in nine (9) treatment combination replicated three times in a Completely Randomized Block Design (CRBD)”. The result shows that application of treatment 100:60:50 kg ha-1 NPK + 6t ha-1 vermicompost has greater effects on growth and yield of okra. The treatment 100:60:50 kg ha-1 NPK + 6t ha-1 vermicompost observed highest plant height of okra (77.47 cm), No. of leaves plant-1 (33.62), No. of branches plant-1 (38.01), No. of fruits plant-1 (19.87), and Yield (135.59) q ha- 1 compared to other treatments. Maximum Gross return (222885 ha), Net return (182494 ha) and B: C ratio (1:2.10) were recorded in treatment with the application of 100:60:50 kg ha-1 NPK + 6 t ha-1 vermicompost as well. Based on the above results obtained in this experiment, the application of 100:60:50 kg ha-1 NPK + 6 t ha-1 vermicompost gave the significant effects on growth and yield of okra.
