Rainfall determines the potential of any region in terms of crops to be grown, farming system to be adopted and the nature and the sequence of farming operations to be done. In the present study analysis of 30 years’ rainfall data revealed that normal kharif rainfall of 740.2 mm in the study area appeared sufficient for normal water requirement of the regional crops of semi Dantiwada Taluka of Gujarat. Based on the forward calculation, probability analysis and average of weekly rainfall for the period from 1988-2017 it was found that 27th to 28th SMW appeared to be the onset of monsoon and appropriate period for the timely sowing of kharif crops. The average weekly rainfall (? 30 mm) was available at comparatively higher probability 67.20 % and 54.11% in 30th SMW and 31st SMW respectively, useful for all the crops at initial growth stages. For interculturing operation probability of occurrence of weekly rainfall <10 mm was found< 20% in 29th and 30th SMW week found suitable for pearl millet crop at tillering stage. Similarly, for plant protection measures probability of occurrence of weekly rainfall (<20 mm) was found to be 80 % found to be suitable during 38th SMW for pearl millet to protect from eargot, semi-looper in castor and pink ball warm in cotton. The weekly rainfall analysis and pattern revealed that kharif crops like pearl millet, green gram and castor were found most appropriate for the region
