Abstract:

A field experiment was conducted during kharif 2016 at Crop Research Farm, Department of Agronomy, SHUATS, Allahabad, (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) and 2 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 attributes 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 attributes viz., cob weight with husk (325.27 g), cob weight without husk (250.30 g), Average grains row-1 (35.30), Average grain rows cob-1 (16.00), Average grains cob-1 (564.80) and 100-Grain Weight (23.93 g) were recorded maximum in ‘sweety’ variety in treatment T8 (Sweety + 60 kg P2O5 ha-1). These parameters were significantly influenced by application of 60 kg P2O5 ha-1as DAP. However, number of green leaves plant-1 at 80 DAS, RGR, Cob length and number of cobs plant-1 were found to be non- significant.
