Effects of salinity and planting depth on the cultivare PEA ALDERMAN

To evaluate the effect of sodium chloride salinity and depth of planting, on stem length traits, number of leaves after ۱۲ days and number of days to seedling emergence in tested PEA ALDERMAN genotypes by using three levels of sodium chloride salinity (salinity ۰.۵%, salinity ۱.۵% and ۲% salinity) three planting depths (۱, ۲ and ۳ cm) and PEA ALDERMAN genotype in factorial randomized complete block design with three replications. Analysis of variance showed that there were significant differences for the three traits evaluated between the depths of planting. But between the levels of salinity, only for the two traits of stem length and leaves after ۱۲ days there was significant difference at the ۵% level. Based on the results of the comparison of factors, maximum stem length and the number of leaves after ۱۲ days of sowing depths of ۱ and ۲ cm and least of all about the planting depth was three inches. The results showed that with increasing depth of planting, the number of days to germination increases. Also the results of the mean surface salinity showed that all traits except days for germination was affected by salinity and with increasing concentrations of sodium chloride in irrigation water, stem length and the number of leaves is reduced after ۱۲ days.
