Effect of Different Salinity Levels on the Yield and Yield Components of Wheat Cultivars

Statistical analysis of the data revealed that yield and yield components of Wheat cultivars were significantly (p<0.05)affected by different salinity levels.Agronomic characters i.e. plant height, tillers plantG 1 , number of grains plantG 1 , 100 grains weight, grain and straw yield and harvest index of two salt tolerant cultivars (Mutant and Lu 26S) were reduced less than salt sensitive cultivars (Yecora and WS 711).Mutant and Lu 268 proved more salt tolerant than other cultivars at all growth stages.It could be concluded from these findings that grain yield was more adversely affected by salinity than straw production.
