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

The research was conducted during the Rabi 2020-2021 and 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 were B.D, P.D, % pore space, water holding capacity, and pH were as, the present macro- micro nutrients in soil and also the morphological parameters have significant findings which comprises color is yellowish brown sandy loam textured neutral to alkaline soil that is non- saline in nature among all the treatment combination applied. The OC, NK observed significantly medium to high in treatment T16 RDF (120:60:40 NPK kg ha-1) + Zinc@20 kg ha-1+ Boron @5 kg ha-1), micro-nutrients such as Zinc, Boron were knowingly medium to high in T16 RDF (120:60:40 NPK kg ha-1) + Zinc@20 kg ha-1+ Boron @5 kg ha-1). The maximum mean value for bulk density (1.33 Mg m-3), particle density (2.589 Mg m-3) percent pore space (47.98%), and percent maximum water holding capacity (45.87%) were found. The chemical soil parameters with a cumulative mean of slightly saline soil pH (7.93), average Electrical conductivity (0.41 dS m-1), maximum percent OC (0.42), high Available N (288.52 kg ha-1), high Available P in T2 (16.85 kg ha-1) due to the antagonistic effect of zinc on Phosphorous, high Available K (207.98 kg ha-1), high Available Zn (1.144 mg kg-1), and high Available B (1.243 mg kg-1) were categorized in evaluation to other NPK and micronutrients levels treatments.
