Impact of Vermicompost and Zinc Implementation on Soil Physico-Chemical Properties After Harvest of Mung Bean

Abstract

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.

Effect of Different Levels of Organic Manures on Physico-Chemical Properties of Soil under Cowpea Crop in an Inceptisol of Prayagraj, Uttar Pradesh, India

“…The result observed in treatment T 1 nonsignificantly higher bulk density (1.32 Mg m ) and significantly higher percentage pore space (48.92% and 45.47%) and Water holding capacity (43.96% and 40.38%) were recorded in T 9 at 0-15 cm and 15-30 cm depth. This corroborates with the findings of [13,7,5,14,4,15,6,11,16,17].…”

“…There was a significantly higher percentage of organic Carbon (0.49 % and 0.47 %), Available Nitrogen (301. 14 ) were recorded in T 9 at 0-15 cm and 15-30 cm depth [2,3,13,7,5,14,4, 15,6,11,16].…”

Impact of NPK and Vermicompost on Physico-chemical Properties of Soil of Cluster Bean (Cyamopsis tetragonoloba L.) Cv. Pusa Navbahar

“…Pore space and water holding capacity of the post-harvest soil were found to be significant. Similar findings were also observed [19,20], and [21].…”

“…The data in the table stated that the lowest available nitrogen (265.51 kg ha -1 and 263.29 kg ha -1 ), available phosphorus (14.87 kg ha -1 and 14.27 kg ha -1 ), and available potassium (178.36 kg ha -1 and 172.66 kg ha -1 ) was measured in treatment T1 (Absolute control) at 0-15 cm depth and at 15-30 cm depth, respectively, and T9 (NPK @ 100% + Vermicompost @ 100%) recorded the highest available nitrogen (288.05 kg ha -1 and 285.22 kg ha -1 ), available phosphorus (25.28 kg ha -1 and 24.28 kg ha -1 ) and available potassium (201.36 kg ha -1 and 193.73 kg ha -1 ) at 0-15 cm depth and at 15-30 cm depth, respectively. Similar findings were also observed [19,20], and [21]. With the help of these physico-chemical properties of the soil, it can be determined that treatment T9 is better followed by treatment T8.…”

Impact of Different Levels of NPK and Neem Cake on Soil Health under Cowpea (Vigna unguiculata L.) Var. Gomati

“…The cake's residual oil and limonoids repel insects, and solvents or water extracts make the product a strong antifeedant and growth inhibitor. The seed cake is rich in plant nutrients (crude protein 13-18%, carbohydrate 24-50%, crude fiber 8-26%, fat 2-13%, ash 5-18% and acid insoluble ash 1-17%, with nitrogen, phosphorous, calcium, and magnesium) and is used as manure for soil amendment and for urea coating" [6].…”
