(a) Effect of foliar spray with sodium selenate (Na₂SeO₄), selenium nanoparticles (GA-SeNPs), and sodium sulphate (Na₂SO₄), each at 0.0, 1, 5, 10, and 50 µM and interaction between sodium sulphate with either sodium selenate or selenium nanoparticles, each at 0.5, 2.5 and 5 µM on growth characteristics of red kidney bean (Phaseolus vulgaris L.) plants at 75 days from sowing. Each result is a mean of 6 replicates. Statistical analysis was carried out using Duncan test. Different letters show significant variation at 0.05 P. Vertical bars represent ± SE.
