Alfalfa is one of the most important forage crop that is highly adaptivity to environment unfavorable conditions. High genetic diversity, yield quality and quantity have made alfalfa the most utilised crop in world. One of the most important factors which decreases yield and plantig area is soil and water salinity. Selection for tolerant genotypes with suitable planting management would lead to increase yield and cultivation area in saline conditions. Adding Ca'* to environment by its antagonistic effects on Na* leads to decrease toxiciticeffect of Na*. Therefore, Four cultivars namely Golestan (20313), Sistan and Bluchestan, F.A.O (2566) and Ahar Hamedani were arrangedin an experimental design to study the Ca2* effectson growth and yield in saline conditions. Experiment was conducted in RBCD based factoriel in 5 salinity levels in 3 replicates at hydroponic culture. The cultivars were grown in saline condition untill the firstcuffing and then the pots were leached with distilled water. Salinity and Ca'* levels were added in Hougland nutrient solution and applied the pots. Shoot, root, stem and leaf dry matter, biomass, plant height, main root length, stem internod numbers and tiller numbers per plant were measured Dry matter production has the rnost significant correlation with stem dry weight in salinity (R50.962). Using Ca" decreases the salinity effect on above factors, especially in resistant cultivar.Golestan (20313) and F.A.O (2566) cultivars had the most dry matter in Ca" and saline conditions.
