Abstract:
A field experiment was conducted during rabi 2021-22 at Agriculture Instructional-cum-Research Farm, IGKV, Raipur. The experimental design was Randomized Block Design having three replications and 7 treatments. The crop lentil and variety chosen was CG Masoor^-1. Recommended dose of fertilizer (RDF) i.e. N: P2O5: K2O: S: 20: 50: 20: 20 kg ha^-1 was applied as basal dose and seed inoculation with Phosphate Solubilizing Bacteria (PSB) and rhizobium @ 5 gm kg^-1 seed at the time of sowing was commonly applied to all treatments. The treatment consist of T₁: RDF 100% (Control), T₂: RDF 100% + 0.5% ZnSO₄ at pre flowering and pod initiation, T₃: RDF 100% + 0.5% FeSO₄ at pre flowering and pod initiation, T₄: RDF 100% + 0.5% ZnSO₄ + 0.5% FeSO4 at pre flowering and pod initiation, T₅: RDF 100% + Seed priming with 0.05% ZnSO₄ solution W/V soaked for 3-4 hours, T₆: RDF 100% + Seed priming with 0.05% FeSO₄ solution W/V soaked for 3-4 hours and T₇: RDF 100% + Soil application of ZnSO₄ @ 20 kg ha^-1. The initial phases of crop growth did not show a significant response to treatments; however, at 60 DAS, 90 DAS and harvest, the highest growth-related characteristics, including plant height, number of branches, number of leaves, leaf area, leaf area index and dry weight of plant were significantly increased with the application of RDF 100% + Soil application of ZnSO4 @ 20 kg ha^-1. The increase in seed and stover yield of crop observed more significantly with the application of RDF 100% + Soil application of ZnSO₄ @ 20 kg ha^-1. Also, the highest zinc content in seed was observed with the application of RDF 100% + Soil application of ZnSO₄ @ 20 kg ha^-1 and highest iron content in seed was observed with the application of RDF 100% + 0.5% FeSO₄ at pre flowering and pod initiation.
