Abstract: The field experiment was conducted at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) during Rabi, 2023. The treatments consisted of three levels Potassium levels (20 kg/ha, 30 kg/ha, and 40 kg/ha) and boron (1 kg/ha, 1.5 kg/ha and 2 kg/ha). The experiment was laid out in a Randomized Block Design with ten treatments each replicated thrice. The treatments which are T₁: Potassium 20 kg/ha + Boron 1 kg/ha, T₂: Potassium 20 kg/ha + Boron 1.5 kg/ha, T₃: Potassium 20 kg/ha + Boron 2 kg/ha, T₄: Potassium 30 kg/ha + Boron 1 kg/ha, T₅: Potassium 30 kg/ha + Boron 1.5 kg/ha, T₆: Potassium 30 kg/ha + Boron 2 kg/ha, T₇: Potassium 40 kg/ha + Boron 1 kg/ha, T₈: Potassium 40 kg/ha + Boron 1.5 kg/ha, T₉: Potassium 40 kg/ha + Boron 2 kg/ha, T₁₀: Control (80:40:40) NPK kg/ha. Application of Potassium 40 kg/ha along with Boron 2 kg/ha (treatment 9) recorded significantly higher plant height (184.44 cm), maximum number of branches/plant (14.8), higher plant dry weight (24.01 g), maximum number of siliqua/plant (125.75), maximum number of seeds/silique (15.13), higher test weight (3.41 g), higher seed yield (2135.15 kg/ha), higher stover yield (4043.38 kg/ha) and highest harvest index (35.76%). The maximum Gross returns (136795.99 INR/ha), Net return (97295.99 INR/ha) and B:C (2.46) were also recorded with application of Potassium 40 kg/ha along with Boron 2 kg/ha (treatment 9) was found to be productive as well as economically feasible.
