Chandigarh, January 12 Changing meteorological trends and climatic variables in arid regions of Haryana over the past 45 years has shown an increase in the yield of kharif season crops, which may indicate further increasing trends if other factors are not limiting, a new study claims. Analysis of yield data from 1972-2016 revealed that cotton lint yield increased at a maximum rate of 17.5 percent, followed by pearl millet at 7.8 per cent, rice at 3.1 per cent and barley at 2.7 per cent. No significant trend, however, was observed in wheat, gram and pigeon pea yield during the study period. The increasing trend in yield was found to be more in kharif season crops as compared to the same during rabi season.
