Abstract

Decision Support System for Agrotechnology Transfer (DSSAT) was calibrated and evaluated to simulate maize (zea mays L.) var. BH660 under current and future climate in Ethiopia under moist mid-highlands of Ethiopia around Ambo Zuria district. Simulations for both current and future periods were run assuming present technology, current varieties and current agronomy packages to investigate rain-fed Maize yield responses. Simulations was made using downscaled weather data from five General Circulation Models (GCMs) under the Coupled Model Inter-comparison Project phase 5 (CMIP5) and two Representative Concentration Pathway (RCP 4.5 and 8.5) by mid-century show a mixture of increase and decrease in median Maize yields. Five GCMs project yields to increase by 5% - 23.0% and one GCM show a decrease by 2% - 9%. Model simulations under the remaining three GCMs give contrasting results of increase and decrease.
