Abstract
Two field experiments were conducted during two successive early summer seasons of 2003 and 2004 on a sandy soil of El-Gsbeel farms, South Sinai. Egypt. to evaluate the effect of using the regional high salinity groundwater from representative wells (WQ 1 = 0.88 dS/m as cntrol, WQ2= 1.90. WQ3= 3.98. WQ4= 6.20. WQS; 10.00 dS/m) in surface drip (SO) and subsurface drip (SSD) irrigation of tomato (Lycopersicon esculentum Mill .. cv. GS) . Tomato rooting depth, shoot weight, fruit weight. fruit height, and fruit diameter significantly decreased with increasing salinity of the irrigation water relative to the control (WQ1). The reductions were about 16.3, 19.4, 25.8, and 58.1 % tor root length, respectively; while the corresponding reductions were 4.4,8.7,44.0. and 69.1% for shoot weight; and 16.9, 25.9. 55.9, and 64% for fruit fresh weight. Fruit height and fruit diameter exhibited a similar trend but in a Jesser magnitudes. On the other hand. fruit total soluble solids (TSS) and vitamin C concentrations significantly increased with increasing salinity and were attributed to the reduction in fruit dry weights. Subsurface drip irrigation (20 cm below bed surface) significantly increased rooting depth and shoot weight compared to the SD one. Simple correlation coefficients among the studied parameters revealed that fruit weight or fruit size were significantly and positively correlated with root length and shoot weight and negatively with irrigation water salinity.
