Abstract
Field experiment was conducted during Rabi 2021 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil in the experimental plot was sandy loam texture, almost 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 arranged in a Randomized Block Design with nine treatments each replicated three times based on a one-year experiment with different levels of Phosphorous and Potassium. The results showed that application of 70 kg/ha Phosphorous + 25 kg/ha Potassium was recorded significantly Plant height (162.73 cm), No. of leaves/plant (13.26), Plant dry weight (108.06 g/plant), Cobs/Plant (1.34), Length of Cob/plant (19.29 cm), Girth of Cob/plant (7.64 cm), Cob weight with husk (65.09 g), cob weight without husk (23.63 g), cob yield with husk (15.14 t/ha), Cob yield without husk (5.16 t/ha) as compared to other treatments.
