Effect of integrated nutrient management on yield and economics of summer sesame (Sesamum indicum L.)

A field experiment entitled “Effect of integrated nutrient management on yield and economics of summer sesame (Sesamum indicum L.)” was conducted at Agronomy farm, College of Agriculture, Nagpur during summer season of 2024. Summer sesame was grown on clay soil, medium in nitrogen, low in phosphorous and rich in potash having pH 7.8. The experiment was laid out in randomized block design with nine treatments T1 - 100% RDN (25 kg ha-1), T2 - 75% RDN + 25% N through FYM, T3 - 75% RDN + 25% N through FYM + Azotobacter 25 g + PSB 25 g kg-1 seed, T4 - 75% RDN + 25% N through Vermicompost, T5 - 75% RDN + 25% N through Vermicompost + Azotobacter 25 g + PSB 25 g kg-1 seed, T6 - 50% RDN + 50% N through FYM, T7 - 50% RDN + 50% N through FYM + Azotobacter 25 g + PSB 25 g kg-1 seed, T8 - 50% RDN + 50% N through Vermicompost, T9 - 50% RDN + 50% N through Vermicompost + Azotobacter 25 g + PSB 25 g kg-1 seed. Yield attributing characters viz., number of capsule plant-1, number of seeds capsule-1 and seed yield plant-1 along with seed and straw yield (q ha-1) recorded significantly higher with application of 100% RDN (25 kg ha-1) and found at par with application of 75% RDN + 25% N through Vermicompost + Azotobacter 25 g + PSB 25 g kg-1 seed. The highest GMR, NMR and B:C ratio of summer sesame were recorded with application of 100% RDN (25 kg ha-1).
