IMPACT OF VERMICOMPOST AND ZINC IMPLEMENTATION ON SOIL PHYSICO-CHEMICAL PROPERTIES AFTER HARVEST OF MUNG BEANUDIYATA KUMARI, AMREEN HASAN, TARENCE THOMAS, ARUN ALFRED DAVID, RAGHU NANDAN SINGH KHATANA AND UTTAM KUMARAbstract At Research Farm, Department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj a field experiment was undertaken in the kharif season 2021-2022, with 9 treatments and 3 replications, the experiment was set up in a Randomized Block Design (RBD) includes Particle density ranged from 2.09 Mg m-3 to 2.26 Mg m-3 in 0-15 cm soil depth and 2.30 Mg m-3 to 2.37 Mg m-3 in 15-30 cm soil depth, bulk density ranging from 1.193 Mg m-3 to 1.290 Mg m-3 at 0-15 cm soil depth and 1.247 Mg m-3 to 1.365 Mg m-3 in 15-30 cm soil depth, Porosity ranged from 44.71 percent to 46.18 percent in the 0-15 cm of soil, but as depth increased, porosity declined, with the depth at 15-30 cm Porosity ranged from 40.39 percent to 43.93 percent. At 0-15 cm and 15-30 cm soil depths as due to the implementation of vermicompost and zinc a considerable impact on soil pH, EC, and Organic Carbon. At 0-15 cm soil level, available nitrogen content ranged from 177.00 kg ha-1 to 227.17 kg ha-1, while at 15-30 cm soil depth, available nitrogen content ranged from 184.60 kg ha-1 to 192.12 kg ha-1. In the 0-15 cm and 15-30 cm soil depths founded maximum available Phosphorus and available Potassium. The available zinc concentration in soil varies from 0.360 ppm to 0.570 ppm at 0-15 cm depth and 0.290 ppm to 0.530 ppm at 15-30 cm depth. |
