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

Abstract

A field experiment was carried out in Zaid 2022 at the Department of Agronomy's Agricultural Research Farm in Prayagraj (U.P).The three planting geometries used in the experiment are 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 fertiliser, 50% of the RDN through inorganic fertiliser in combination with 50% of Nitrogen provided through FYM with Azotobacter seed inoculation, and 50% of the RDN through inorganic fertiliser. Ten treatments were duplicated three times in the randomised block design of the experiment. Findings showed that 30x10cm spacing ,Maximum plant height (124.48 cm), dry weight (29.85 g), number of capsules/plant (78.69), number of seeds/capsule (36.39), and seed yield (552.38 kg/ha) were obtained with 5% RDN + 50% N via FYM + Biofertilizer (Azotobacter).
