Abstract

Salt tolerance threshold is determined by considering the yield reduction rate in saline media compared to non-saline conditions. This value can be used for comparing salt tolerance among crop varieties. To determine salt tolerance threshold of WHEAT, a field experiment arranged as spilt plot in completely randomized block design was conducted with three replications.Experimental treatments were irrigation with saline water (2, 5, 8, 11, 14 and 20 dS.m-1) and WHEAT cultivars, namely, Kavir, Roshan, Mahoti and Marvdasht. Results showed that salt tolerance threshold values for Kavir, Roshan, Mahoti and Marvdasht were 5.0, 4.6, 3.3, and 5.7 dS.m-1, respectively. With each increase in salinity level above the salt tolerance threshold, grain yield of Kavir, Roshan, Mahoti and Marvdasht was reduced by 4.5, 4.1, 4.5, and 5.5 percent, respectively. The salinity at which the yield is reduced by 50% were 15.1, 16.0, 13.0 and 12.9 for Kavir, Roshan, Mahoti and Marvdasht, respectively. Based on the U. S. Salinity Laboratory rating, these cultivars are moderately salt tolerant.
