Response of NPK, Zinc and Boron Fertilization on Physico-chemical Properties of Soil under summer Green Gram (Vigna radiate L.) Cultivation in an Inceptisol of Prayagraj, (Uttar Pradesh)

Abstract

The study pertaining to the present topic under field investigation is entitled "Response of N, P, K, Zinc and Boron fertilization on Soil Health, Growth and Yield Attributes of Summer Green gram (Vigna radiata L.) in an Inceptisol of Prayagraj, Uttar Pradesh" for two consecutive years, beginning from the summer seasons of the years 2021 and 2022 at Research Farm, Department of Soil Science and Agricultural Chemistry. Before conducting research operations, an excavated soil sample from the experimental site revealed that the land topography ranged from nearly level to 1-3% slope, the soil is of sandy loam texture with near neutral in reaction (7.62), the electrical conductivity was non-saline (0.23 dS m-1) in nature, the low organic carbon content (0.29%), the low to medium available N (146.62 kg ha-1), available P (13.78 kg ha-1) and available K (207.15kg ha-1). The best results were seen with treatment (T11), which was made up of RDF (20:40:20 NPK kg ha-1) + Zinc@6 kg ha-1+ Boron@3 kg ha-1. This treatment used NPK and different micronutrient (Zinc and Boron) levels at the same time. regard to physical soil parameters, the cumulative mean value for bulk density (1.27 Mg m-3), percent pore space (47.74%), particle density (2.67 Mg m-3) and percent maximum water holding capacity (43.68%) were increased and chemical soil parameters with a cumulative mean of slightly saline soil pH (7.81), average electrical conductivity (0.37 dS m-1), medium available N (275.93 kg ha-1), medium available P in T2 (21.07 kg ha-1) due to the antagonistic effect of zinc on Phosphorous, medium available K (230.38 kg ha-1), high available Zn (0.623 mg kg-1), and high available B (0.616 mg kg-1) were labeled in comparison to other NPK and micronutrients levels treatments.
