Crop simulation models have been used to evaluate the effects of different management practices on final crop yield. A crop model interfaced with a GIS can facilitate the visualization of the different effects of crop inputs. The objective of this study was to simulate maize crop yield using AEGISWIN an interface of DSSAT (ver. 4) under different soil input scenarios, including point based and zone based,compared with actual yield monitor data. A 40 ha field was sampled on a 90 m grid at three horizons for soil physical properties. The major soil type of the field identified as Brooksville (Fine, smectitic, thermic Aquic Hapluderts). The DSSAT-Maize model was run within the AEGISWIN interface for each sampling point and zone based averaged soil properties to simulate the maize yield and compared with the actual yield monitor data. The model simulation was evaluated using the root mean square error statistics for each soil input scenario .
