Maize is an important part of the human diet and it accounts for 20% of the total staple food consumed in Nigeria. However maize yield in Nigeria is about 1.7t/ha which is very low compared to global productivity of 4.9t/ha. This study analyzed potential zones for maize production in Nigeria using DSSAT CERES-Maize model. Six sites were selected and a common hybrid maize variety Oba Super 2 grown in Nigeria was used for the study. Weather data for ten (10) years from 2001 to 2010 and soil data collected from previous studies were used. The data were used to run CROPWAT model to generate the irrigation schedules at four (4) levels of soil moisture depletion. The levels chosen were, 40%, 50%, 60% and 70% of critical soil moisture depletion. The irrigation schedules where incorporated into the DSSAT CERES-Maize model to simulate the yield at each level of moisture depletion. The yield was also simulated without irrigation. This was carried out for both the rainy and dry seasons. The results showed that Zaria (North West) and Ibadan (South West) have the highest potentials for maize production while Owerri (South East) has the lowest potential during rainy season and Maiduguri (North East) during the dry season.
Key words: CERES-Maize, CROPWAT, maize, Nigeria, irrigation scheduling.
