Effect of diverse nutrient sources and liquid organic manures on soil nutrient status of sesame (Sesamum indicum L.)

A field experiment was conducted to study “Organic nutrient management in rabi sesame (Sesamum indicum L.)” during 2024-25 at the Agricultural College Farm, Naira. The experiment was laid out in a split-plot design with three replications. The study consists of three main plot treatments viz., 100% RDN through inorganic fertilizers, 100% RDN through organics with biofertilizers and biofertilizers alone. The sub-plots included four foliar applications: Vermiwash, Panchgavya, Jeevamrut and water spray. The results showed thaT₁₀0% RDN organic manures + biofertilizers (M₂) significantly improved post-harvest nitrogen, phosphorus and potassium and foliar application of Panchgavya @ 3% (S₃),whereas organic carbon was maximum under 100% RDN through organic manures + application of liquid biofertilizers (M₂) and foliar application of Jeevamrut@ 10% (S₃) and microbial activity was highest under 100% RDN through organic manures +application of liquid biofertilizers (M₂) and foliar application of Jeevamrut @ 10%(S₃).The study concludes that applying 100% RDN through organic manures along with biofertilizers, combined with foliar spraying of Jeevamrut @ 10%, is the most effective practice for improving soil fertility, microbial activity and sustaining sesame cultivation during the rabi season
