Dynamics of phenological stages of BT cotton based cropping system under different nutrient levels

Abstract

The study was conducted at the Department of Agronomy, Dr. PDKV, Akola, during 2020-21 and 2021-22 to evaluate different Bt cotton-based cropping systems under varying fertilizer levels applied to rabi crops. The experiment was carried out on the same site with the same randomization across both years. Findings indicated that the cropping systems had significant effects on plant height (cm), number of functional leaves, and leaf area of cotton, except at 30 DAS, in both years. With respect to nutrient management, the effects were non-significant in the first year but became significant in the second year for plant height, number of functional leaves, and leaf area, again with the exception of 30 DAS.
