Using suitable rainfall criteria, beginning of monsoon rains suitable for crop sowing, cessation of rainy season from agricultural point of view and the peak values of the rainfall, have been determined and their spatial distribution studied. Correlations of each of these parameters with time were computed to examine the possible trends. Association between number of rainy days and seasonal (monsoon) rainfall with time have also been attempted and discussed. With a view to determine coherence in rainfall pattern in the dry farming region (DFR), an index has been devised from its different sub-regions of the zone. Decadal analysis has also been done to see whether mean rainfall in a decade statistically differed from those in other decades.
