Salinity is one of the major stresses especially in arid and semiarid regions, which severely limit crop production. It impairs seed germination, reduces nodule formation, retards plant development and reduce crop yield. Salinity affects germination and physiology of crops due to osmotic potential which prevents water up take and by toxic effect of ions on embryo viability. This study was conducted to assess the effect of salinity on germination of chickpea (Cicer arietinum L.) in the laboratory of Mekelle University by using NaCl and Na2So4 to simulate salinity and tape water as control group. The seeds of chickpea (Cicer arietinum) landraces were collected from Hagereselam and Samre. Then 10 seeds of chickpea from both sites were treated in each salt concentration in 3 replications designed by using complete random block design. The result of the experiment showed that the concentrations of salt have a negative impact on the germination and growth of chickpea, as a result when the concentration of salt increases, the germination, water uptake and length of root and shoot decreases. Furthermore we found that different salinity simulated having different impacts on germination. Our result clearly indicated that NaCl highly affects germination and growth of chickpea than Na2SO4. Meanwhile, the effect of salinity for both land race have significance difference in parameters of water up take, % of germination, length of root and shoot (t-test n = 25 p<0.05). Our result further indicated that there is a difference in sanity tolerance level between the 2 land races of chickpea.
