Abstract
Normally for an average to good catchment, ratio of command area to catchment of an irrigation project varies from 0.3 to 0.5. But in case of Salandi Irrigation project, the first major irrigation project of Orissa commissioned during 1967, the ratio exceeds unity, i.e., 1.276, which is extraordinary. The theoretical crop water requirement considering the cropping practice in vogue over the command and adopting the parameters considered in the project report works out to 0.858m in Kharif and 1.296m in Rabi. But, it is found that in practice the actual water supplied in the distribution system for the period from1985-86 to 2005-06 during Kharif and Rabi is 0.283m and 0.929m, respectively. This less quantity of water supply for irrigation in the command than the theoretical requirement has not affected the crop yield but has made the agriculture successful. Various aspects of the Project such as the geophysical features of the catchment, hydro-geological formation of the command, soil characteristics, percolation rate through the top soil, amount of rainfall and its distribution, cropping pattern in the command and unusual phenomenon of irrigation practice in the Salandi irrigation command and probable reason for success of this project in providing irrigation over the years with much less quantum of water has been analyzed and presented in this paper.
