A field experiment was conducted during kharif 2016 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 6.7), low in organic carbon (0.35%), available N (230 kg ha-1), available P (20 kg ha-1) and available K (189 kg ha-1). The treatment consisted of 5 levels of Phosphorus viz. P1 (40 kg P2O5 ha-1), P2 (50 kg P2O5 ha-1), P3 (60 kg P2O5 ha-1) P4 (70 kg P2O5 ha-1) and P5 (80 kg P2O5 ha-1) whose effect is observed on sweet corn varieties viz. V1 (Sweet Glory) and V2 (Sweety). There were 10 treatments each replicated thrice. The experiment was laid out in Randomized Block Design. The result showed that growth parameters viz., plant height (213.00 cm) at 80 DAS, number of green leaves plant-1 (5.87) at 40 DAS, Dry weight (200.77 g) at 80 DAS and CGR (32.52 g m-2 day-1) at 80 DAS and yield and yield attributes viz., cob weight with husk (325.27 g), cob weight without husk (250.30 g), No. of seeds row-1 (35.30), No. of seed rows cob-1 (15.80), No. of seeds cob-1 (500.53), 100-Grain Weight (23.93 g), Green cob Yield (5.32 t ha-1) and Green fodder Yield (13.45 t ha-1) were recorded maximum in treatment T8 (Sweety + 60 kg P2O5 ha-1). Maximum net return of 80134.91 and B.C. ratio 2.77 was recorded in treatment T8 (Sweety + 60 kg P2O5 ha-1).
