The quality of irrigation water deteriorated in semi-arid region because of over
exploitation of ground water.An investigation on effect of irrigation water quality
on yield and water use efficiency of irrigated wheat crop was carried out on
farmers fields at typical ravine watershed located at Etmadpur, Agra. The study
comprised of Green manure (T ), 25% more seed rate and fertilizer than
recommended dose (T ), T + gypsum (100% neutralization of RSC value of
irrigation water) (T ), T + FYM (10 t ha y ) (T ), and Farmers practice (T ) were
imposed. The results indicated that water quality had pronounced effect on soil
physico-hydrological properties and affected the yield of wheat crop. Imposition
of treatment of gypsum and FYM has improved yield and water use efficiency of
wheat crop in all the three sites. Mean yield across different sites ranged from 27 to
35 q ha under different treatments. In general, imposition of treatment over
farmer's practice (100% NPK) resulted in improvement of yield of crop in all the
sites. Application of gypsum based on 100% neutralization of RSC value of
irrigation water resulted in significant improvement of crop yield and water use
efficiency of crops.
