Abstract: Salt stress limits soybean production in vast areas worldwide. It has been found that increases salinity resulted in decrease of chlorophyll contents in soybean leaves. Effect of foliar application of ascorbic acid and inoculation of mycorrhizal arbuscular fungi on chlophyll content of soybean was studied in saline soil with EC 4– 5 mmhos/cm. The experiment was laid out in split-split plot design with three replications. The treatments consisted of two variety of saline tolerant soybean (non-selected soybean and F4 selected soybean) in main plots, ascorbic acid concentration (0 and 500 ppm) in sub plots. Mycorrhizal arbuscular fungi inoculum namely without inoculum (control), Glomus sp-1, Glomus sp-2, Glomus sp-3, Glomus sp-4, Glomus sp-5, and combined of all mycorrhizal inoculum were the sub-sub plot treatments. The parameters observed were chlorophyll a, b and total by using Henry and Grime (1993) method. The results showed that F4 selected soybean tolerant salinity, foliar application of ascorbic acid, inoculation of myorrhizal arbuscular fungi and interaction all of treatment significantly increased chlorophyll a, b and total chlorophyll of soybean leaves in saline soil.
