| The study was conducted in order to assess the impact of climate change on faba bean (Vicia faba L.) yield and to investigate the possible options for overcoming these negative impacts. To find out the negative effect of climatic change (CC) on faba bean yield, a field trial was carried out at Sakha Agricultural Research Station during the two successive winter growing seasons 2013/2014 and 2014/2015. The investigation consists of four irrigation intervals ; Treatment A: rainfall treatment i.e. given only the planting irrigation and left to rainfall during the growing season (control), Treatment B: given one irrigation following the planting one, Treatment C: given two irrigations after the planting irrigation and Treatment D: given three irrigations following the planting irrigation. The Decision Support System for Agrotechnology Transfer (DSSAT) is the simulating model which compare the observed values obtainded from the experiment with that predicted by the model. To run thus program, input elements of weather, parameters of both soil and faba bean were used. Without adaptation scenario, by using the climatic data, Pods and Seeds with decreased from -12.43 to -26.11% and from -9.32 to -23.16% for yield of pods and seeds, respectively in the years 2025 to 2100. The adverse impacts of CC could be minimized under adptation scenario of deleying one month from current planting data. The corresponding values of pods and seeds will be decreased from -6.34 to -20.11% and from -5.41 to -16.26%, respectively. In conclusion, DSSAT was able to simulate dry bean crop parameters under current conditions with a difference from 0.4 to 0.7% compared to the actual yield. The main results showed that: the impact of CC on faba bean production was evaluated using CC scenario A1 by the year 2025, 2050, 2075 and 2100 comparing with that predicted under the current conditions of season 2013/2014 and 2014/2015. Mean air temperature is projecting to an increase between 1.9 and 2.5 ºC during faba bean growing seasons for 2025 to 2100. | ||||
