| Summary: | Today, the importance of legumes is underestimated in most countries. Not only does it play a crucial role in the diet of millions of people in developing countries, but the United Nations also encourages the consumption of these edible seeds as an alternative source of animal protein. Iran is one of the major exporters of legumes, especially chickpeas, and accounts for one percent of global production of legumes. This study was aimed to investigate chickpea production and adaptability strategies under future climate change conditions to achieve maximum grain yield. Climatic data on the baseline (1981–2010) was used as input for general circulation models to run RCP4.5 and RCP8.5 scenarios, to compare with predicted data for near (2021–2050) and far (2051–2080) climate change and to determine the extent of climate change. The CROPGRO-Chickpea model from DSSAT software was used to simulate the effects of climate change and evaluate adaptation strategies. Under RCP4.5 and RCP8.5, the grain yield was improved by 1.0 % and 17.1 %, respectively, in near climate change and by 2.3 % and 11.0 % in far climate change compared to baseline (1215/48 kg ha−1). Early sowing of different cultivars improved grain yield, with ILC482 cultivar showing the shortest phenological development stage and the highest grain yield under climate change. In conclusion, a combination of early cultivars and early sowing date can be an appropriate management strategies for chickpea production in Kermanshah region under climate change. |
