Combined Effect of Salinity Potassium Humate on Growth and Physiology of Soybean (Glycine max L).

These experiments were conducted to study Potassium Humate's effect on soybean growth and yield. Seeds were sown in pots and a single dose of Potassium Humate was applied in a single dose and water as a control. Soybean was grown in salt-affected soil to check the salt tolerance of soybean. Potassium Humate addition maintained higher contents of soil water, salt, and mineral nitrogen in the wetting pattern by enhancing the soil water-holding capacity. The obtained results indicated that the addition of KH increased all the studied growth parameters, i.e. plant height, number of leaves, leaf area, stem diameter, and canopy dry weight.  The soil application of KH was highly effective at improving the growth and yield of bean plants by alleviating the inhibitory effects of soil salinity stress. Results showed that Potassium Humate improved soil physical and chemical properties of soil which positively reflected on plant growth and productivity mineral nutrients (N, P, K, and Ca).
