Effect of application of PGPR, potassium silicate and their combination on the concentration of (A) sodium ions and (B) potassium ions in faba bean leaves growing under two irrigation types, i.e., fresh water (FW) and saline water (SW) in salt-affected soil during two growing seasons 2018/2019 and 2019/2020. The data are means ± SD of four replicates. Means values that have the same lower-case letter in each column per season are not significant according to Duncan’s Multiple Range Test.
