This study was conducted to determine the effects of different irrigation water salinity and leaching rates over germination and initial growth of clover. Experiment were carried out in the lysimeter conditions for six months. The three different irrigation water salinity levels (0.25 dS m-1, 1.5 dS m-1 ve 3.0 dS m-1) and the four leaching rates (10%, 20%, 35% and 50%) were used in randomized block design with three replications. Plant fresh weight (yield) and dry weights (biomass) were measured to evaluate the impacts of irrigation water salinity and leaching rates. It was observed that both irrigation water salinity and leaching rates had significant impacts on yield and leaching rates had significant effects over biomass. The highest yield was obtained from the treatment with 1.5 dS m-1 salinity level and 50% leaching rate.
