Abstract
A field experiment was conducted aiming to study the influence of Spacing and Boron levels on growth and yield of black gram during Zaid season 2022. The treatments comprised of row spacing (25, 30, 35 cm) and boron at (1.0, 1.5, 2.0 kg/ha). The results show that application of boron 2.0 kg/ha at 35 × 10 cm spacing has recorded significantly higher plant height (44.53 cm), number of branches per plant (9.27), number of nodules (35.53) and dry weight (10.44 g). However higher number of pods per plant (30.73), seeds per pod (6.40), test weight (42.48 g), seed yield (930.33 kg/ha) and stover yield (2040.33 kg/ha) gross return (Rs 58,610.79/ha), net return (Rs 34,311/ha) and B:C ratio (1.41) were recorded with the application of boron 2.0 kg/ha at 25×10 cm spacing. Therefore, the spacing of 25×10 cm and application of Boron @ 2.0 kg/ha could be a promising option for the yield enhancement in black gram.
