the effects of humic acid and calcium on morpho-physiological traits and mineral nutrient uptake of pistachio seedling under salinity stress

the study was carried out to evaluate the effects of soil application of humic acid and calciumon morpho-physiological traits and na+, mg2+, ca2+ uptake of pistachio seedling (akbari) grown under salt stress.  a completely randomized design was used with four replications in greenhouse conditions. the experimental treatment consisted of four levels of humic acid (bis humic) (0, 4, 8 and 12 gr kg-1 soil) and anti-salt as a source of ca+2 (0, 1, 2 and 3 gr kg-1 soil). results indicated that humic acid and  anti-salt significantly increased vegetative growth, such as root fresh and dry weight, stem diameter, leaf number and leaf area, of pistachio seedling in comparison with the control group (p
