Influence of Biofertilizers and zinc Sulphate on yield and economics of Maize (Zea mays L.)

The field experiment was carried out during Rabi season of 2022 at the Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj (U.P.) India, to study effect bio- fertilizers and zinc sulphate on growth yield Maize. treatments consist Bio-fertilizers PSB, Azotobacter, PSB + Azotobacter ZnSO4 (20, 25, 30 kg/ha) soil experimental plot sandy loamy in texture, nearly neutral reaction (pH 7.8), low organic carbon (0.35%). outcomes showed that higher plant height (159.03 cm), dry weight (162.70 g/plant), crop rate (26.250 g/m2/day), number cobs/plant (1.8), rows/cob (16.8), seeds per cob (553.4), 100 seed (29.3 gm), Grain (6.5 t/ha) straw (12.9 t/ha), Harvest index (33.8) were significantly influenced with application kg/ha. Higher gross return (INR 1,49,119.5/ha), net 1,08,439.5.00/ha) B:C ratio (2.66) also recorded treatment No.9 (PSB kg/ha).
