Abstract:
The field experiment was conducted during Zaid, 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.) on sandy loam soil. The experiment laid out in Randomized Block Design consisting of 10 treatments which are replicated thrice i.e., comprising of plant growth regulator spraying twice at 20DAS and 40DAS T₁: 40kg P₂O₅/ha + 0.10ppm Brassinolide, T₂: 40 kg P₂O₅ /ha + 0.25ppm Brassinolide, T₃: 40kg P₂O₅/ha + 0.50ppm Brassinolide, T₄: 50 kg P₂O₅/ha + 0.10 ppm Brassinolide, T₅: 50kg P₂O₅/ha + 0.25ppm Brassinolide, T₆: 50kg P₂O₅/ha + 0.50 ppm Brassinolide, T₇: 60 kgP₂O₅/ha + 0.10ppm Brassinolide, T₈: 60kg P₂O₅/ha + 0.25ppm Brassinolide, T_9: 60kg P₂O₅/ha + 0.50ppm Brassinolide, T₁₀: Control plot N:P:K = 20:60:40 kg/ha and The results obtained on growth and yield attributing characters viz., plant height (121.40cm), Nodules (21.14) dry weight (19.5g), branches/plant (4.3), pods/plant (7.2), Seed/pod (12.2), Test weight (121g) seed yield (1915 kg/ha), stover yield (3833 kg/ha) Harvesting index (49.29%) were recorded significantly higher with application of 60kg P2O5/ha + 0.50ppm Brassinolide. and highest Cost of Cultivation (30918.00 INR/ha), Gross return (1,02830.00 INR/ha), Net return (71912.00 INR/ha), B:C ratio (2.32) had also recorded at the same treatment with 60kg P₂O₅/ha + 0.50 ppm Brassinolide.
