Abstract:
A field experiment was conducted during kharif 2020, at Cotton Improvement Project, Mahatma Phule Krishi Vidyapeeth, Rahuri, Ahmednagar (dist.), Maharashtra, India to evaluate the abiotic cause of major disorder i.e., leaf reddening in cotton plants. The main objective of study was on phenological responses of cotton plants studied using three different genotypes in three different irrigation environments and sown during three different intervals of time. Phenological parameters such as days for first square formation, days to 50% flowering and days for first boll opening were critically observed. The experiment was carried out in double split plot design, replicated thrice. Extra late sowing time, waterlogged environment and Bt hybrid i.e., Rashi 659 have taken more number of days for first square formation, days to 50% flowering and days for first boll opening.
