摘要：Field experiment was conducted under 3 different planting dates and 5 nitrogen levels to assess the impact of modified weather on yield and biomass of rice using CERES-Rice at Agricultural Research Institute, Acharya N. G. Ranga Agricultural University, Hyderabad. The percent error was 7 and -11.4% in grain yield when crop was planted on 25th July and 29th August, respectively. Increase biomass was observed with increasing levels of nitrogen from 100 to 300 kg /ha. Grain yield has decreased with elevated temperatures during entire crop growth and reduced solar radiation during flowering to beginning of grain filling in all the dates of planting and nitrogen levels
