| Abstract | ||||
| The effect of salt concentration in irrigation water (tap water, 2000 and 4000 ppm) and ground water table depth (40, 70 and 100 cm from the surface) with respect to their interaction on chemical com-position of sugar beet (Variety; Despres Poly N) were studied. The results indicated that lowering the ground water table up to 100 cm from the surface significantly increased total soluble solids, sucrose percentage, and potassium concentration in root as well as chlorophyll A and potassium concentration in leaves. Contrarily to this trend was observed regarding sodium concentration of roots and leaves. Increasing the salt concentration in irrigation water up to 4000 ppm significantly increased total soluble solids in root juice, free praline concentration in leaves and sodium concentration for both leaves and roots. On the other hand, increasing concentration in both roots leaves. While, sucrose percentage, chlorophyll B and carotenoids were not affected by irrigation with saline water up to 4000 ppm. Interaction effect of ground water depth and irrigation with saline water had no significant effect on all studied constituents of sugar beet. INTRODUCTION | ||||
