Abstract: A field experiment entitled, “Integrated nitrogen management in summer sesamum (Sesamum indicum L.)†was conducted at Post Graduate Research Farm, Agronomy Section, RCSM College of Agriculture, Kolhapur during summer 2018 on sandy loam soil. The nine treatments consisting of GRDF (T1), no fertilizer (T9), 100% RDN (50 kg N ha-1) through inorganic fertilizer (T2), combination of 75% RDN through inorganic fertilizer + 25% N through organic sources viz., FYM (T3), vermicompost (T4), neem cake (T5). Similarly, 75% RDN through inorganic fertilizer + 25% N were equally applied (12.5% + 12.5%) through combination of organic sources viz., FYM + vermicompost (T6), FYM + neem cake (T7) and vermicompost + neem cake (T8) in randomized block design replicated thrice. INM levels show discernible influence on growth characters, yield attributes and yield of sesamum. Among the integrated nitrogen management treatments, an application of 75% RDN through inorganic fertilizer + 25% N through vermicompost (T4) and 75% RDN through inorganic fertilizer + 12.5% N through FYM + 12.5% N through vermicompost (T6) were comparable and found beneficial in increasing growth attributes viz., plant height (101 cm), number of leaves plant-1 (32.80), number of branches plant-1 (7.57), leaf area plant-1 (10.16 dm2) and dry matter production plant-1 (32.00 g) at harvest while, yield attributes viz., capsules plant-1 (42.93), capsule length (3.53 cm), seeds capsule-1 (76.51), weight of seeds plant-1 (4.84 g), test weight (3.27 g), grain yield (12.15 q ha-1) and straw yield (21.87 q ha-1) except GRDF. Based on economics, an application of 75% RDN through inorganic fertilizer + 25% N through vermicompost (T4) secured the maximum net realization of Rs. 57,965 ha-1 with BCR of 2.53.
