Abstract: The study was carried out at the Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P), India during Kharif 2023. The soil of the experiment area had a sandy loam texture, The soil reaction is almost neutral (pH 7.8), the organic carbon content is low (0.62%), the available N is 182 kg/ha, the available P is 32.2 kg/ha, and the available K is 240.7 kg/ha. The experiment consisted of 9 treatments and 3 replications. The treatments combinations were T1: 2nd fortnight of June + Spacing 20 cm × 10 cm, T2: 2nd fortnight of June + Spacing 30 cm × 10 cm, T3: 2nd fortnight of June + Spacing 40 cm × 10 cm, T4: 1st fortnight of July + Spacing 20 cm × 10 cm, T5: 1st fortnight of July + Spacing 30 cm × 10 cm, T6: 1st fortnight of July + Spacing 40 cm × 10 cm, T7: 2nd fortnight of July + Spacing 20 cm × 10 cm, T8: 2nd fortnight of July + Spacing 30 cm × 10 cm, T9: 2nd fortnight of July + Spacing 40 cm × 10 cm. The highest maximum plant height (64.58), dry weight (10.56), number of pods per plant (14.68), number of seeds per pod (8.64), test weight (44.53 g), and seed yield (1.88 t/ha) were recorded for seeding on July 1st fortnight at 30 cm × 10 cm (Treatment 5). Maximum gross return (Rs. 1,35,476.41/ha), net return (Rs. 98,140.41/ha), and B:C ratio (2.63) were also recorded for the previously mentioned treatment.
