The rainfall characteristics, frequency of meteorological and agricultural drought, water-use yield relationships of pearl millet and kharif pulses of arid Churu District were studied. The meteorological droughts prevailed in 28 out of 101 years (1906-2006) whereas, agricultural drought occurred in 18 out of 33 years (1971-2003). The actual evapotranspiration during reproductive stage of pearl millet and kharif pulses gave significant correlation with grain yields. Regression relationships of grain yield of pearl millet with rainfall explained 68% of the yield and with actual evapotranspiration 72-74%. Kharif pulses were less susceptible to drought than pearl millet attributed to difference in growth duration.
