Abstract

A field experiment was conducted during Zaid 2024 at the Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P.), on sandy loam soil with neutral pH (7.2), medium organic carbon (0.53%), low nitrogen (182.56 kg/ha), medium phosphorus (27.8 kg/ha), and high potassium (253.4 kg/ha). The experiment followed a Randomized Block Design with nine treatments and control plot replicated thrice. Among the treatments, the application of phosphorus at 40 kg/ha combined with brassinolide at 50 ppm (T6) resulted in the highest values for plant height (71.77 cm), number of nodules per plant (33.7), plant dry weight (35.52 g), number of pods per plant (17.5), seeds per pod (10.9), test weight (24.95 g), seed yield (1248.49 kg/ha), and stover yield (3388.63 kg/ha).
