Field experiment was conducted during kharif, 2013 at college farm, Prof. Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad. The soil of experimental field was sandy loam in texture, alkaline in reaction (pH 8.02), free from salts (EC 0.39 dsm-1), low in organic carbon (0.88%), available nitrogen (210kg ha-1), available phosphorus (14.14 kg ha-1) and potassium (249.76 kg ha-1). The investigation was carried out with three plant densities (1, 3 and 5 seedlings hill-1) and four age of seedlings (15, 25, 35 and 45 days old seedlings). Model evaluation revealed that simulation of phenology at heading and physiological maturity was considered as excellent with NRMSE of 3% and 3%, with lesser RMSE values of 2.0 days and 3 days respectively. However, simulation of total biomass and grain yield was good with NRMSE of 14% and 12%, having RMSE values of 1711 and 683 kg ha-1 respectively. So model can be used as a research tool in the variable agro-environments of Telangana State to suggest suitable management practices to rice under low land transplanted conditions.

Keywords: CERES Rice Model evaluation, Plant densities, Age of seedlings, Transplanted rice.
