Agro-climatic variations in the growth rates of area, production and productivity of pearl millet [Pennisetum glaucum (L) R. Br. emend. Stuntz] in arid region of Rajasthan were studied. The study was conducted for 1956-57 to 1966-67 (pre-green revolution) and 1967-68 to 1987-88 (post-green revolution) period in 4 micro-units, viz arid rainy-season (kharif) monocropping, arid irrigated kharif winter-season (rabi) cropping, kharif monocropping and irrigated rabi and kharif cropping of western Rajasthan. Compound growth rate in the ama during post-green revolution period was less than that during pre-green revolution period in all the 4 micro-units. Its growth rate during green-revolution period was found significant and positive in all the micro-units except in arid irrigated kharif and rabi cropping. Similarly. compound growth rate of production during pre-green revolution period was higher than that under post-green revolution period. Compound growth rate of productivity was non-significant in the post-green revolution period and was less than that in pre-green revolution period in all the 4 micro-units.
