The field trial was carried in Zaid season of 2021 at SHUATS Model of Organic Farm (SMOF), Naini Agricultural Institute, SHUATS, Prayagraj (U.P.). The objective was to study the growth and yield of Black gram as influenced by crop geometry and seed pelleting with botanicals under certified organic production system. The experiment was laid out in a randomized block design to study the effect of seed pelleting with leaf powders of three botanicals, viz., Pongamia pinnata, Prosopis juliflora, and Albizia lebbeck, and sown in three different row spacings of 20 cm, 30 cm, and 40 cm, on the growth and yield of black gram. The results revealed that black gram seeds pelleted with Albizia leaf powder and sown at row spacing of 30 cm reported maximum plant height (43 cm), dry weight (12.49 g/plant), number nodules per plant (27.50), seeds per pod (7.07), test weight (42.19 g), grain yield (872.96 kg/ha), and haulm yield (2511.11 kg/ha) which was significantly superior to other treatments.
