Abstract
Growth water samples has been collected from wells in different tomato plantation which situated inclusively the western desert to south world of Basrah city.The above water wells situated in the Areas wichis: Al-Barjesia, Al-Luhais and the southern Najmei Area. These samples has been submitted to analysis in order to specify chemical specification such as ECiw (pH) TDs, SAR, adj-SAR. The evaluation and classification of the samples were classified according to the (Richards, 1954) USSL. (Ayers and Westcot, 1985) FAO. (TGPC, 1995) and (Follett and Soltanpour, 2001). The results revealed that (pH) values were inclusive the neutral limits of the yields growth but there is altitude in the values of the electrical conductivity (EC) and the concentration of soluble cations and anions for wells water throngh the steps of water collection. This altitude due to the scarcity of the rains during the study period. As well as the wide use of unsuitable pumping the ground water caused big changes to the quality of the water and scarcity. Oneouther reason the draft of the bad quality water gathering caused scarcity of tomatoes yield comparatively with past seasons. Results also indicated that the water of wells inclusive the class C4S1 which means high salinity water with afew of sodium element according to the classification of (Richrds, 1954) USSL. If we depend on classification of the values of TDs, so we can consider that the water of the wells has moderately saline according to the classification of TGPC (1995) ; within increase in permeability hazard in FAO system ; and increasing toxicity hazard for toxicity based on (Cl¯) concentration that cause too much hard problem directly on the yields. We can not from the results that the concentration of the heavy metals in water samples do not couse any problem when we use in irrigation. Also we can find from the results that the everage of total yield of tomato decrease comparatively with the farmer studies to the same area. Results also indicated that there is capability for using these water fore irrigation in case for no existence of fresh water, in that case we need a good management system.
