Effect of Biofertilizers and Potassium on Yield and Economics of Yellow Mustard (Brassica campestris L.)

A field experiment was carried out at Crop Research Farm, during Rabi 2021, Department of Agronomy, SHUATS, Prayagraj (Uttar Pradesh) to study the effects of biofertilizers and potassium on the yield and economics of yellow mustard. Biofertilizers (Azotobacter, Phosphate-Solubilizing Bacteria) and Potassium levels (35, 40 and 45 kg/ha) were organized in a Randomized Block Design experiment. The treatment with Azotobacter at 10 g/kg seed + PSB at 10 g/kg seed + Potassium at 40 kg/ha resulted in a higher 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%). In respect to all other treatment combinations, the application of Azotobacter at 10 g/kg seed + PSB at 10 g/kg seed + Potassium at 40 kg/ha resulted in the highest gross returns (91,800.00 INR/ha), net returns (60,642.40 INR/ha) and benefit cost ratio (1.95).
