Abstract

In regions of erratic and scanty rainfall, it is important to know probability of dry and wet spell on weekly basis during growing season of crops. The probability of wet spell if coincides with the sensitive phonological stages, it may be detrimental to crop, on the other hand the dry period at ripening stage of the crop is somewhat beneficial. The variation in rainfall from agricultural management is much more important when considered on weekly basis. The analysis showed that the more chance of occurrence of dry spell at MW 44 to 45 in all talukas of Jalna district so care has to be taken that fertilizer application hoeing and weeding should be avoided. Probability analysis of occurrence of dry and wet spells provides the relevant information for different intercul tural operations and can be useful for farm planning. The data studied in the project revealed that the probability of occurrence of 2 weeks dry spell was highest in 44^th MW while the probability of occurrence of 4 weeks dry spell was highest in 42th MW. So crops like maize can be sown dry which will be germinate just after the rains and can sow the time of land preparation.
