Abstract

Field experiments were conducted during the 2014/15 and 2015/16 cropping season at Holetta, Kulmsa, Ambo, Agricultural Research centers and Kuyu testing site of Holetta. The cultivars namely, Gora, Gebelcho, Dagem and Walki released for Nitisols and vetisols were used to calibrate and evaluate CSM- CROPGRO- faba bean model in Ethiopia. The model inputs ( crop management information, soil and daily weather data including maximum and minimum air temperatures, precipitation and solar radiation were used for calibrate and evaluation of CSM- CROPGRO- faba bean model in Ethiopia. The statistical indices used to measure model performance during calibration for days to flowering, days to maturity and grain yield showed a good agreement between the measured and simulated values. The performance of the calibrated model was also evaluated against the independent data set of experiments carried out in 2015 cropping season. The model evaluation indicated a good agreement between measured and simulated days to flowering (RMSE = 4 days; d = 0.92), maturity (RMSE = 7 days; d =0.93), and grain yield (RMSE= 0.6 t ha^-1; d = 0.8).In general, the current crop simulation model obtained after calibration and evaluation can be use in model applications o assess water- limited and potential yield, yield gaps and in closing yield gaps. Such information can assist plant breeder in the recommendation of cultivars to the target environment and determine management practices in both nitisols and vertisols. The objective of this study was to calibrate and evaluate CSM-CROPGRO-Faba bean model to estimate cultivar genetic coefficient in the highlands of Ethiopia
