This study was conducted to investigate the desalinizing effect of some vegetable crops (beet, crown daisy, kale, lettuce, spinach, sweet corn, and tomato) in salinized soil. The soil was treated with highly concentrated nutrient solutions and the growth of these crops was compared and soil salinity was monitored. The plant height of lettuce and crown daisy inhibited severely in with EC 5 dSㆍm-¹ salinized soil. Soil EC level was the lowest in soil where tomato was cultivated followed by corn and kale. The residual level of NO₃ was higher in soils used for cultivation of corn, tomato, and kale, that of K was higher in soils used for cultivation of corn, tomato, and beet, and That of P₂O∧5 was higher in soils used for cultivation of corn and tomato.
