Climate change, the defining challenge of our generation, is no longer a distant threat, but an emerging reality. High temperature, an imminent product of global climate change, will affect agriculture through direct and indirect effects on crops. The daily minimum night time temperature increased at a faster rate than daily maximum temperature in the last century and differential increase in day and night temperature occurs in many parts of the world. Two rice cultivars, Pusa 44 and Pusa Sugandh 2, were subjected to various thermal treatments such as normal ambient temperature (T0), high day and night temperature (TI) (+2.7°C during day and night), high day temperature T2 (+3°C during daytime only) and high night temperature T3 (+2.4°C during night time only) from transplanting to maturity. The study revealed that high day and night temperature (Tl) followed by high night (T3) and high day (T2) temperature treatments drastically affected the crop growth, yield and quality.
