Abstract
The hydro-salinity system of the two adjoining watercourses was studied over an eight-year period. Different sources of irrigation contribute about 1390 tonnes of salts in the rootzone annually. This figure represents 79.50% through tubewells, 11.30% through canal supplies and the remaining 9.20% due to dry period capillarity. The removal of salts was estimated to be 1153 tonnes with 41.40% due to over irrigation, 32.50% from rainfall during irrigation, 9.70% through watercourse losses and remaining 6.40% taken up by various crops, causing a net addition of 0.63 tonnes of salts per hectare annually.
