Abstract:
A field experiment was conducted during Zaid 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out in Randomized Block Design with nine treatments each replicated thrice on the basis of one year experimentation. The treatments which are T₁: 50 kg/ha Phosphorus + 5 kg/ha Zinc, T₂: 50 kg/ha Phosphorus + 15 kg/ha Zinc, T₃: 50 kg/ha Phosphorus + 25 kg/ha Zinc, T₄: 60 kg/ha Phosphorus + 5 kg/ha Zinc, T₅: 60 kg/ha Phosphorus + 15 kg/ha Zinc, T₆: 60 kg/ha Phosphorus + 25 kg/ha Zinc, T₇: 70 kg/ha Phosphorus + 5 kg/ha Zinc, T₈: 70 kg/ha Phosphorus + 15 kg/ha Zinc, T₉: 70 kg/ha Phosphorus + 25 kg/ha Zinc are used. The results showed that application of 70 kg/ha Phosphorus + 25 kg/ha Zinc was recorded significantly higher Cobs/Plant (1.46), Length of Cob/plant (17.30 cm), Girth of Cob/plant (7.28 cm), Cob weight with husk (63.01 g), cob weight without husk (20.65 g), cob yield with husk (13.30 t/ha), Cob yield without husk (5.16 t/ha). However, gross returns (Rs.95303.33/ha), net return (Rs.64363.21/ha) and benefit cost ratio (2.08) was obtained in the treatment of 70 kg/ha Phosphorus + 25 kg/ha Zinc as compared to other treatments.
