Abstract
To investigate the effect of irrigation water quality and moisture content on Tomato plant yield under covered cultivation using drip irrigation system, field experiment was conducted in aplastic house in College of Agriculture- University of Baghdad at winter season 2009-2010. The experiment was split plot design within a randomized complete blocks design with three replicates and two treatments. First treatment was irrigation water quality including: Abu- Graib river water, mixed water consisted of 50% Abu- Graib river water + 50% General Drain water and General Drain water. Second treatment was water depletion including: irrigation at 40, 60, and 80% of available water. There was a significant increase in early yield for river and mixed water treatments of 50 and 48% respectively comparing with drainage water .Irrigation scheduling by water depletion 60% significantly increased early yield comparing with 40 and 80% available water. Irrigation with mixed water led to the highest total yield of 4.15Mg .house⁻¹ with an increase of 12% comparing with irrigation with river water and drain water. Using mixed water led to higher WUE of 1.10 kg m-3 water with a significant increase of 13% comparing with river and drainage water under the conditions of this study. These results indicated that using drip irrigation system is a suitable method for saline water management.
