Abstract:
A field experiment was conducted during Rabi 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out in Randomized Block Design with nine treatments each replicated thrice on the basis of one year experimentation. The treatments which are T₁: Nitrogen 40 kg/ha + 30 x 15 cm, T₂: Nitrogen 40 kg/ha + 40 x 15 cm, T₃: Nitrogen 40 kg/ha + 50 x 15 cm, T₄: Nitrogen 60 kg/ha + 30 x 15 cm, T₅: Nitrogen 60 kg/ha + 40 x 15 cm, T₆: Nitrogen 60 kg/ha + 50 x 15 cm, T₇: Nitrogen 80 kg/ha + 30 x 15 cm, T₈:Nitrogen 80 kg/ha + 40 x 15 cm,T₉: Nitrogen 80 kg/ha + 50 x 15 cm are used. The results showed that application of Nitrogen 80 kg/ha + 50 x 15 cm was recorded significantly higher Plant height (149.10 cm), No. of Branches/plant (12.18), Plant dry weight (22.13 g/plant) Siliuae/plant (179.24), Seeds/siliquae (29.37), Test weight (3.26 g), Harvest index (34.13%). However, significantly highest Crop growth rate (11.01 g/m²/day) was recorded with the treatment of Nitrogen 80 kg/ha + 30 x 15 cm, highest Seed yield (1609.13 kg/ha), gross returns (Rs.99766.07/ha), net return (Rs.67503.03/ha) and benefit cost ratio (2.09) was obtained in the treatment of Nitrogen 80 kg/ha + 30 x 15 cm as compared to other treatments.
