Description In the attempts for rational development of agriculture in the arid and emi-arid regions of the world, knowledge regarding suitable means for rapidly evaluating climate and moisture adequacies is important and crucial. Effective estimation of the climatic water balance over large areas depends to a large extent on the available supply and the ability to estimate potential demand. Mean monthly rainfall provides a general idea about the available supply. Hargreaves (1977) indicated that 75% probability of rainfall occurrence is a much more reliable indication of moisture available for crop production than mean precipitation. With this idea, we are listing the dependable precipitation (DP) amounts for all the locations. Dependable precipitation is defined as the precipitation that has a specified probability of occurrence (in this case at least 3 to 4 years) based on an analysis of longtime precipitation records. Potential evapotranspiration (PE) gives an idea regarding the potential demand for water at a given location. It is defined as the amount of water transpired from an actively growing, short green plant cover (usually grass) with a full crop cover and a continuously adequate moisture supply. PE values were estimated for all the locations according to procedure described by Reddy and Virmani (1980).
