Abstract

The field experiment was conducted during Kharif season 2022 at Student’s Instructional farm of Acharya Narendra Deva University of Agriculture and Technology Kumarganj, Ayodhya Uttar Pradesh, India. The experiment was laid out in Randomized Block Design (RBD) with three replications and ten treatments. The experiment comprised of ten treatments viz., T1: Control, T2: 100% RDF (150, 60, 40 N, P2O5, K2O kg ha-1), T3: 100% RDF + 25 kg ZnSO4 ha-1 soil application, T4: 100% RDF + 0.5% ZnSO4 spray at tillering stage, T5: 100% RDF + 0.5% ZnSO4 spray at tillering stage + PI stage, T6: 75% RDF + 25 kg ZnSO4 ha-1 soil application, T7: 75% RDF + 0.5% ZnSO4 spray at tillering stage, T8: 75% RDF + 0.5% ZnSO4 spray at tillering stage + PI stage, T9: 75% RDF + 25% FYM-N +0.5% ZnSO4 spray at tillering stage + PI stage and T10: 75% RDF + 25% FYM-N +25 kg ZnSO4 ha-1 soil application. The application of 75% RDF + 25% FYM-N +25 kg ZnSO4 ha-1 soil application has non-significantly effect on Bulk density, pH, Electrical Conductivity of soil after harvest of rice crop. The application of 75% RDF + 25% FYM-N +25 kg ZnSO4 ha-1 soil application has significantly influenced Organic carbon, Available N, P, K and Zn in soil.
