“…CERES (Crop Estimation through Resource and Environment Synthesis)-Rice and -Maize are process-based models embedded in DSSAT simulate the main processes of crop growth and development such as phenological development, canopy leaf area growth, dry matter accumulation and grain yield. The CERES-Rice andMaize models were evaluated by many researchers across locations (Sarkar and Kar, 2006;Timsina and Humphreys, 2006;O'Neal et al, 2002;Behera and Panda, 2009;Liu et al, 2011;He et al, 2012;Salmerón et al, 2012;Jeong et al, 2014;Ngwira et al, 2014) with good agreements between predicted and observed values. Even though simulation results generally will have some uncertainties associated with inputs and model parameters, but still the simulation models can be effectively utilized as a scientific tool to increase the resource use efficiency of cropping systems (Timsina and Connor, 2001;Sarkar and Kar, 2008;Timsina and Humphreys, 2006;Timsina et al, 2008).…”
