western Rajasthan compared to eastern Rajasthan. The studyindicates the possibility of improving yield under mild droughtconditions in western Rajasthan through better managementpractices.40 Rao, K.N. (1958)Some studies on rainfall of Rajasthan with particular reference totrends. Indian Journal of Meteorology and Geophysics. 9: 97-116The rainfall of all the provincial raingauge stations in Rajasthan hasbeen studied. A comparison of 1920 and 1940 district normals hasbeen made. A comparison of 1901 to 1930 and 1901 to 1940 averageswith 1901 to 1950 average has been made for individual stationsand trend, if any has been determined. Rainfall of east and westRajasthan has also been studied. It is concluded that the rainfallseries over a long period up to 1954 does not show any significantchange in the history of rainfall in the area.41 Ratnam, B.P. and Joshi, S.N. (1977 )Drought frequency at Hagari and Bijapur. Annals of Arid Zone. 16:171-175The occurrence of drought during the monsoon in two typical aridstations of Karnataka state was studied. Hagari experienced 10drought spells and Bijapur 9 during a study covering a period of 20years (1954-73). The elements of water balance for the normal aswell as for the disastrous drought years have been discussed.Maldistribution and low amounts of rainfall have been considered tohave the four disastrous droughts.42 Ratnam, B.P. and Joshi, S.N. (1977 )Weekly water balances of normal and severe drought years atDharwar. Annals of Arid Zone. 16: 1-4A comparative study was made of the weekly balances, for thekharif season, of the normal and severe drought years, at a dryhumid station, Dharwar. In the drought year, water deficiencyoccurred during 12 out of the 17 weeks of rainy season, whereas thecorresponding figures for a normal year were 5 out of 17 weeks. Therole of a 3-week spell of above normal rains, after a prolonged periodof water deficiency in saving the kharif crop was limited.43 Ratnam, B.P. and Joshi, S.N.
