Field experiments which aimed at assessing the effect of onion and celery irrigation with water of various salt content were done in 1999-2000 on sandy soil. The average yield increase caused by irrigation was 55.8 percent for celery and only 3.9 percent for onion. Tap water caused the highest increment of onion yields (by 15.4 percent). Celery responded best to diluted saline water which increased the yield by 72.8 percent, tap water by 53 percent and saline water by 41 percent as compare with the non-irrigated control. Supplemental irrigation increased the photosynthetic activity of vegetable leaves, i.e CO2 assimilation, transpiration and carbon dioxide concentration in substomatal cells, to the greatest extent when plants were irrigated with tap water
