It would be preferable to use a reliable crop growth model for studies on climate change impact assessment. The objectives of this study were to evaluate simulation performance for models CERES-Maize included in the DSSAT model (version ) in terms of yield. Three hybrids 900M, Pinnacle and CP818 were grown under four dates June II FN, July I FN, July II FN and August I FN during kharif season, 2016 at . Agricultural college, Tirupati to study the ‘Seasonal influence on yield of maize and its validation with CERES-Maize model’. | Seasonal influence on yield of maize and its validation with CERES-Maize Model M.
