Physiological behavior of rice cultivars under different sowing dates

The investigation was carried out during kharif 2021 at Institute of Rice Research, Professor Jayashankar State Agricultural university, Rajendranagar, Hyderabad. The experiment was laid out in split plot design with three replications. Treatments consist of two dates of sowing i.e., July 1st week and July 3rd week. Transplanting was done with respective 25 days old seedling with 2-3 seedlings per hill. Cultures in sub plot consist of KPS 6251, WGL 1246, RDR 1162 and check variety RNR15048 and JGL 24423. At Different dates of sowing the grain yield was non-significant and Among different cultivars, higher grain yield was recorded with JGL24423 (7073) and was at par with KPS6251(6905), WGL1246 (6702) and RNR 15048 (6679). Lowest grain yield was recorded with RDR1162 (5854). Interaction effects were significant.
