| Abstract | ||
| The impact of climate change on yield and water consumptive use for peanut was evaluated under north Egypt environmental condition ( Noubaria region) by using crop simulation model (DSSAT 3.5) . The model first was calibrated and validated to evaluate it’s ability to simulate and predict water consumptive use and yields using data collected form field experiments establish at private farm at El –Hossian village, Noubarai region. The experiments conducted involving three water regimes (irrigating at 100, 80 % of the daily potential evapotranspiration “ETp”” and farmer application) Giaz 5 cultivar was planted during two successive summer seasons of,2010 and 2011 years . The data were used together with the region environmental data under climate change scenarios. These climate change scenarios were HadCM3 ‘A2’ (temperature increase by 3.1°C and CO2 concentration is 834 ppm) and HadCM3 ‘B2’ (temperature increase by 2.2°C and CO2 concentration is 601 ppm) developed by Hadley Center for Climate Prediction and Research(United Kingdom). Calibration/ Validation results reveal that model was acceptable and accurate under study condition. Results reveal that climate HadCM3 B2 scenario recorded the maximum increase in peanut consumptive use compared with A2 scenario. Furthermore, A2 scenario predicted greater reduction in peanut grain and biomass yields, compared with B2 scenario. The adaptation irrigation treatment gave a slight percent increase in water requirement and minimal percent reduction in yield. | ||
