Improving Tolerance of Faba Bean during Early Growth Stages to Salinity through Micronutrients Foliar Spray

Year: 2010

Type: article

Abstract: Salinity, either of soil or of irrigation water, causes disturbances in plant growth and nutrient balance. Previous work indicates that applying nutrients by foliar application increases tolerance to salinity. A pot experiment with three replicates was carried out in the green house of NRC, Cairo, Egypt, to study the effect of micronutrients foliar application on salt tolerance of faba bean. Two concentrations of a micronutrient compound (0.1% and 0.15%) were sprayed in two different treatments prior to or after the salinity treatments. Levels of NaCl (0.00-1000-2000-5000 ppm) were supplied to irrigation water. Results indicated that 2000 and 5000 ppm NaCl inhibited growth and nutrient uptake. Spraying micronutrients could restore the negative effect of salinity on dry weight and nutrients uptake, when sprayed either before or after the salinity treatments. It is suggested that micronutrient foliar sprays could be used to improve plant tolerance to salinity.
