Abstract
Seasonal temperature is an important climatic factor which can have profound effects on the yield of crops. Climate change is a concern today, and researchers are engaged in understanding its impact on growth and yield of crops, and also identifying suitable management options to sustain the crops' productivity under the climate change scenarios. The effect of increase in temperature on grain yield of some winter crops (wheat, mustard, barley and chickpea) in northwest India was evaluated on the basis of historic records and through a dynamic crop growth model, WTGROWS. The optimal date of sowing was also evaluated in view of the increase in seasonal temperature. The yield of these crops, especially wheat, already showing signs of stagnation in most places of northwest India, is most likely to be affected by temperature changes. The solar radiation-temperature interactions study in wheat reveals some interesting trends and is seen to vary from one location to another. Keeping in view the trends in global climate change, a shift in sowing time, as an adaptation strategy is recommended. The simple and empirical relations between yield and seasonal temperature change can be well used for a crude estimate of yield dependence of temperature rise of
