The Effects of Humic Acid, Fulvic Acid and Salt Stress on Qualitative and Quantitative Characteristics of PlantagoOvata

The Effects of Humic and Fulvic acids and different concentration of irrigation salinity on qualities and quantities property of Plantagoovata were examined. Treatments consisted control (Zero levels of Humic and Fulvic acid), and Humic and Fulvic acid at concentrations of 50 and 100 mg/lit. The concentration of NaCl in irrigation water was zero, 50 and 100 mmol/lit. A completely randomized design was employed as experimental design with three replication. The results showed that, humic and fulvic acid at 50 mg /lit, significantly increased thousand seed weight, percentage of seed proteins, leaves chlorophyll content and the concentration of Potassium, Calcium and sodium in plant biomass and also reduced salinities stress.
