Abstract:
The field experiment was conducted during zaid season of 2021 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P). The soil of the experiment plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.82%), available N (291.24 kg/ha), available P (32.85 kg/ha) and available K (264.78 kg/ha). The treatments consisted of three sources (Azotobacter seed treatment), (KSB seed treatment), (potassium levels 30, 40, 50kh/ha) and one control plot, respectively. The experiment was laid out in randomized block design with ten treatments and were replicated thrice. Result defined that maximum plat height (222.60 cm), dry weight (229.5g/plant), crop growth rate (27.44g/m² /day), cobs (1.6/pant), row /cob (15.03), seeds/row (25.07), seed yield (7.97t/ha) and Stover yield (11.50t/ha), harvest index (40.91%), test weight (243.33g), maximum gross returns (1,59,400/ha), net returns(1,24,245.3/ha), and benefit: cost ratio (2.94) were obtained in the treatment combination of Azotobacter + KSB + potassium 50kg/ha compared to other treatments.
