Abstract
The field experiment was conducted during Rabi season 2022 at experimental field of Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, Uttar Pradesh, India. The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH7.3), low in organic carbon (0.36%), available nitrogen (171.57 kg/ha), available phosphorus (15.4 kg/ha) and available potassium (232.7 kg/ha). The research consists 3 levels of Phosphorus 30, 40, 50 kg/ha and Potassium 15, 20, 25 kg/ha. The experiment was layout in Randomized Block Design with 9 treatments each replicated thrice. Significantly higher plant height (25.20 cm), plant dry weight (10.34 g), and the yield attributes namely seeds/pod (2.27), pods/plant (91.90), seed yield (1847.93 kg/ha) and stover yield (2948.20 kg/ha) was with the treatment 9 [Phosphorus 50 kg/ha + Potassium 25 kg/ha].
