Abstract:
A field experiment was conducted during Kharif 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: Sole Maize + 25% RDN + 75% FYM + Biofertilizers, T₂: Sole Maize + 50% RDN + 50% FYM + Biofertilizers, T₃: Sole Maize + 75% RDN + 25% FYM + Biofertilizers, T₄: Sole Cowpea + 25% RDN + 75% FYM + Biofertilizers, T₅: Sole Cowpea +50% RDN + 50% FYM + Biofertilizers, T₆: Sole Cowpea + 75% RDN + 25% FYM + Biofertilizers, T₇: Maize + Cowpea (1:2) + 25% RDN + 75% FYM + Biofertilizers, T₈: Maize + Cowpea (1:2) + 50% RDN + 50% FYM + Biofertilizers, T₉: Maize + Cowpea (1:2) +75% RDN + 25% FYM + Biofertilizers used. The results showed that Sole Maize + 75% RDN + 25% FYM + Biofertilizers was recorded significantly higher Plant height (173.89 cm), Plant dry weight (148.68 g/plant), crop growth rate (41.38 g/m²/day),Cobs/Plant (2.67), cob length (23.60 cm), Cob weight (89.39 g), Grains/cob (371.37), seed index (26.05 g), Seed yield (6391.63 kg/ha) and Straw yield (9247 kg/ha) in Maize crop.
