Impact of Zinc and Boron on Physico-chemical Properties of Soil under Green Gram Crop in an Inceptisol of Prayagraj, Uttar Pradesh, India

Abstract

The research entitled “Impact of Zinc and Boron on Soil Health Parameters and Yield Attributes of Green gram in an inceptisol of Prayagraj U.P., India” conducted at the department of Soil Science and Agricultural Chemistry Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, U.P during the Zaid 2021-2022. The experiment was laid out in Randomized Block Design with sixteen treatments and three replications with four levels of Zinc and Boron along with NPK as RDF. The non-significant findings that is B.D, P.D, % pore space, water holding capacity, and pH were as, macro- micro nutrients, in soil and also the morphological parameters have significant findings which comprises yellowish brown sandy-loam textured neutral to alkaline soil that is non- saline in nature between all the treatment combination applied. The OC, NPK were founded significantly medium to high in treatment T16 RDF (20:40:20 NPK kg ha-1) + Zinc@6 kg ha-1+ Boron @3 kg ha-1, micro-nutrients such as Zinc, Boron were knowingly medium to high in treatment T16 RDF (20:40:20 NPK kg ha-1) + Zinc@6 kg ha-1+ Boron @3 kg ha-1. the maximum mean value for Bulk density (1.34 Mg m-3), Particle density (2.588 Mg m-3) percent pore space (47.63%), and percent supreme water holding capacity (46.25%) were found. The chemical soil parameters with a cumulative mean of slightly saline soil pH (8.35), average electrical conductivity (0.419 dSm-1), maximum percent O.C. (0.427), high Available N (284.62 kg ha-1), high Available P in T2 (16.60 kg ha-1) due to the antagonistic effect of zinc on Phosphorous, high Available K (206.93 kg ha-1), high Available Zn (1.132 mg kg-1), and high Available B (1.233 mg kg-1) were considered in evaluation to other NPK and micronutrients levels treatments.
