| This study estimated crop water requirements using CROPWAT while AQUACROP and CERES models evaluated performance in simulating biomass and grain yield of upland rice’s response to different irrigation schedule. NERICA 4 was subjected to five treatment given as: full (100%ET), good (80%ET), medium (60%ET), average (40%ET), and low (20%ET) and three replicates in a randomized block design. It was planted at the farmyard of the International Institute of Tropical Agriculture (IITA) Ibadan, Nigeria for two seasons 2015 and 2016 and the results of the first season was used in model calibration while second season’s result was used in validation. Biomass and grain yields values were obtained and compared with simulated values from AQUACROP and CERES and the... |
