Effect of Spacing and Nitrogen Management on Yield and Economics of Summer Sesame (Sesamum indicum L.)

A field experiment was carried out in Zaid 2022 at the Department of Agronomy's Agricultural Research Farm in Prayagraj (Uttar Pradesh). There are three planting geometries used in the experiment 30 cm x 10 cm, 40 cm x 10 cm, and 50 cm x 10 cm. There are three nitrogen management treatments used in the experiment 50% of the Recommended Dose of Nitrogen (RDN) through inorganic fertilizer, 50% of the RDN th rough inorganic fertilizer in combination with 50% of Nitrogen provided through Farm yard manure with Azotobacter seed inoculation, and 50% of the RDN through inorganic fertilizer. Ten treatments were duplicated three times in the randomized block design of the experiment. Findings showed that with 30x10cm spacing ,50% RDN + 50% N through Farm yard manure + biofertilizer (Azotobacter) highest grain yield (552.38 kg/ha), net return (30221.00 INR/ha), gross return (71809.00 INR/ha), and benefit: cost ratio (1.73).
