Abstract

In arid and semi arid regions of Iran good quality irrigation water is not available, it is saline to varying degrees. Most of these waters are used in the production of strategic products and in many cases the performance of these products is desirable. Considering the importance and necessity of using saline water in agriculture, determine plant tolerance to salinity, soil and water studies with the aim of exploiting regional and doctrinaire of these resources is special. This study examined the effects of salinity on yield and its components in wheat cultivars a factorial experiment in a randomized complete block design with three replications in Jiroft came into force, Where salinity as the first factor in 5 levels (0, 2/5, 5, 7/5 and 10) ds m and the second as a factor in 2 levels (chamran and vrynak) were studied. Traits such as plant height, number of leaves, number of tillers per plant and biological yield were final. The results showed that the effects of different levels of salinity and increased the number of leaves and biological yield was significant at 1% level. The interaction of salinity and cultivar on plant height, yield, number of tillers per plant were significant at 1% level chamran gave the lowest yield.
