Abstract
Coastal deserts and seawater provide an opportunity and a challenge for the development of agricultural systems that can utilize their resources. The following study was conducted to determine the importance of root-shoot ratio and irrigation timing on the growth and yield of tomato (Lycopersicon esculentum Mill.) grown in sandy soil using dilutions of seawater. Tomato cultivars `VF 36’ and `Globonnie’ were grown in the greenhouse and irrigated with 0, 17 and 33% seawater at either 4:00 AM or 10:00 AM. Cultivars differed significantly in their salt tolerance. Under saline conditions, irrigation at 4:00 AM increased total soluble solids in fruits, days from sowing to fruit set, and ion accumulation in shoots. Plant fresh weight, dry weight, height, cluster number, fruit weight and yield per plant were higher when irrigation treatments were applied at 10:00 AM rather than predawn.
