The DSSAT model was calibrated and evaluated for contrasting varieties of potato (Atlantic, a mid-season variety, and Russet Burbank, a late-season variety) and barley (Robust, a 6-row feed variety, and Newdale, a 2-row malting variety) using 99 field experiments conducted in Maine. The model accurately simulated observed final yield for each variety. Climate change simulations read more Climate change effects on potato production in Maine focus of new study
