Soybean crop has seen phenomenal growth in area and production in India in the recent decade. Future climatic change is likely to have substantial impact on soybean production depending upon the magnitude of variation in CO2 and temperature. Increased temperature signi cantly reduces the grain yield due to accelerated development and decreased time to accumulate grain weight. Therefore, to explore the possibilities of introducing the crop under new environments viz. arid, semi-arid regions and employing options to sustain the soybean production under different anticipated regional climate...
