Abstract :In this study, t he olive mill wastewater at different concentrations insert ignore into journalissuearticles values(control, 1/1, 1/2, 1/3, 1/4 insert ignore into journalissuearticles values(OMW/distilled water); and undiluted OMW); was used to determine the impact to the sainfoin seed germination. In the study, the germination ratio and mean germination time showed statistically significant differences in terms of levels according to treatments, sainfoin populations and sainfoin populations x treatments interaction insert ignore into journalissuearticles values(p<0.01);, g ermination ratio varied at 5-70 % and the highest value insert ignore into journalissuearticles values(70 %); was obtained from 1/2 insert ignore into journalissuearticles values(OMW/distilled water); application in true sainfoin seeds. In general, the OMW insert ignore into journalissuearticles values(added distilled water);  treatments were increased germination ratio. The lowest germination ratio insert ignore into journalissuearticles values(11.67 %); was determined in sainfoin seeds collected from Eğirdir location. According to application, the highest germination ratio was obtained from 1/1 and 1/2 insert ignore into journalissuearticles values(OMW/distilled water); applications. In experiment, mean germination time varied in 5.0-11.0 days. Generally, high OMW concentrations insert ignore into journalissuearticles values(except undiluted OMW); extended mean germination time in sainfoin seeds. In all OMW applications, it shortened in ES seeds, but not in TS seeds. Additionally, germination time weren’t effected as positive from OMW applications insert ignore into journalissuearticles values(except undiluted OMW); in TS seeds. The longest mean germination time insert ignore into journalissuearticles values(9.0 day); was in ES seeds. According to treatments, germination in the shortest time occurred in 1/4 insert ignore into journalissuearticles values(OWM/distilled water); treatment. As a result, olive oil wastewater insert ignore into journalissuearticles values(OMW); mixed to irrigation water in certain dozes may increase seed germination and can be used as fertilizer in agriculture.
