Description
Summary:A greenhouse study was conducted to investigate the response of faba bean ( Vicia faba L.) to water salinity applied at different times of salinization. Faba beans were grown on loamy sand in pots and irrigated daily with modified half-strength Hoagland's solution. Salinization of the nutrient solution with NaCI and CaCl 2 (2:1 molar ratio) provided four treatment solutions with electrical conductivities of 2, 6, 10 and 14 dS m −1 and was imposed on the tenth day from planting, and continued until day 30 (T1), from day 30 until day 50 (T2) and from day 50 to day 70 (T3) using a randomized block factorial design with five replications. The results indicated that faba bean was more sensitive to salinity during the vegetative stage and less sensitive at later stages. Water salinity significantly reduced the grain yield and grain number but did not affect grain weight. Vegetative growth decreased significantly by salinity stress during the three salinization periods but was more serious at the first stage.
