Major crops contributing to food grain production in the arid western Rajasthan are generally cultivated under rainfed situations, also known as kharif season. In this study an attempt was made to quantify the response of rainfall variability on major rainfed crops in this region. Analysis of daily rainfall data during monsoon seasons (Jun–Sept) over past 13 years showed a range of seasonal rainfall from 86 mm to 480 mm. Crop productivity data of major rainfed crops of the region e.g. pearl millet representing cereals, cluster bean and moth bean as pulses and sesame as oilseeds revealed positive correlation between productivity and monsoon rainfall or intramonsoon rainfall (Jul-Aug). Linear trends between the productivity and rainfall during the monsoon season and intra- monsoon period was established for each selected crop. Best trend was observed for cluster bean (R2 = 0.85) and the worst for sesame (R2 =0.63) while the total monsoon rainfall was considered. However, when only the intramonsoon rainfall was considered, best trend was observed for moth bean (R2 =0.72) and the lowest for pearl millet (R2= 0.61). From this study, it was observed that cluster bean yield is more sensitive to total monsoon rainfall than other crops of the region, whereas, moth bean yield was found most sensitive to intramonsoon rainfall.
