Abstract:
A field study was conducted on the Effect of different levels of NPK and Vermicompost on Physico – Chemical properties of soil of Okra (Abelmoschus esculentus L.) Var. Kashi Kranti at the Soil Science & Agricultural Chemistry Research farm of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during summer season 2018. The result obtained with treatment T₅-[NPK@ 50% + Vermicompost @ 100%] that showed the highest pH 7.38, EC 0.50 dSm-1. In post soil of NPK fertilizers observations were resulted in significant increase in OC 0.82%, Particle density 2.71 g cm3, Bulk density 1.44 g cm3, Pore space 53.01% and available N 228.44 kg ha-1, P 23.02 kg ha-1, K 144.87 kg ha-1, significant increase in case of Nitrogen (kg ha-1), Phosphorus (kg ha-1), Potassium (kg 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.
