Abstract:
A field experiment was conducted during Rabi, 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The experiment was laid out in Randomized Block Design with the combination of Biofertilizers (Azotobacter and PSB) and different levels of Potassium (35,40 and 45 kg/ha). Totally there were nine treatments which were replicated thrice. The results revealed that significantly higher plant height (129.83 cm) at harvest and dry weight (9.10 g) at 60 DAS recorded with the treatment Azotobacter at 10 g/kg seed + PSB at 10 g/kg seed + K at 40 kg/ha (T₈). Whereas maximum Crop growth rate (8.30 g/m²/day) at 60 DAS was recorded with the treatment PSB at 20 g/kg seed + K at 40 kg/ha (T₅) and Relative growth rate (0.0333 g/g/day) at 60 DAS was recorded with the treatment Azotobacter at 20 g/kg seed + K at 35 kg/ha (T₁). Yield attributes viz. Number of siliqua per plant (134.53), seeds per siliqua (31.67), test weight (3.40 g), seed yield (1.53 t/ha), stover yield (5.20 t/ha) and harvest index (22.74%) were recorded maximum with the treatment Azotobacter at 10 g/kg seed + PSB at 10 g/kg seed + Potassium at 40 kg/ha (T₈).
