Even in years of good rainfall and availability of water, soaring temperatures owing to climate change could significantly cut into the earnings of farmers, shows a study claiming to be the first of its kind in the State. The variations in yield to temperature of paddy, jowar, toor, and ragi, which covers the major crops sown in the State, were scrutinised in the study “Climate variability and climate change in Karnataka”, commissioned by KAPC (Karnataka Agricultural Price Commission). Unirrigated paddy, jowar grown during the rabi season (September to October), ragi and toor were found to be sensitive to exposure to extreme temperatures; and in the case of jowar, the effect of extreme heat was more than the effect owing to variation in rainfall. Not just that, consecutive days of extreme heat even negatively overwhelmed positive effects of good rainfall and average temperature.
