The field experiment was carried out at soil science research farm of Sam Higginbottom University of Agriculture, Technology and Sciences Allahabad, during Rabi season 2016-17. The design applied was 3x3factorial randomized block design having three factors with three levels of N, P, K @ 0, 50, and 100 % ha-1, three levels of Vermicompost @ 0, 50 and 100% ha-1 respectively. The result obtained with treatment T5-[NPK@ 50% + Vermicompost@ 100%] that showed the highest yield regarding, gave the best results with respect to plant height 115.69 cm, number of leaves per plant 49.33, Number of branch 48.50, Number of Fruit per plant 20.71, it gave highest yield, 199.21 q ha-1, The maximum cost benefit ratio was recorded 1: 8.55and net profit. Rs. 37,154.6 ha-1 in treatment combination T5-L1V2 [@ 50%N P K ha-1 + 100% Vermicompost ha-1] combined use of N, P and K resulted in significant increase on enrichment of soil fertility status. Vermicompost in combination resulted in a slight increase in pH 7.40, EC 0.52 dSm-1. In post soil of N, P, and K fertilizers observations were resulted in significant increase in OC 0.84 %, Particle density 2.73 M gm-3, Bulk density 1.46 M gm-3, Porespace 53.06% and available N 229.48 kg ha-1, P 24.03 kg ha-1, K 147.87 kg ha-1, significant increase in case of Nitrogen (kg ha-1), Phosphorus (kg ha-1), Potassium (kg ha-1), Vermicompost (t ha-1) was found to be significant among other treatments in okra cultivation and soil quality improvement. It was also revealed that the application of NPK with Vermicompost were excellent source for fertilization than fertilizers. The treatment (T5) also showed greater benefit cost ratio followed by other treatments.
