Özet: Drought has become a global problem threatening the world. It causes serious yield losses in agricultural production. This study was conducted in Kahramanmaraş Sütçü İmam University, Faculty of Agriculture and Department of Field Crops Laboratory in February 2019. In this study, parameters of germination and seedling development of Özkaynak, Violetta and Taşkent field pea varieties were examined. Seeds of these varieties were germinated using different drought stress levels [0 (control), -0.6, -1.7, -3.2 and -5.3 bar]. The experiment was established according to the completely randomized experimental design with four replications. Observations were made every day at the same time, seeds with radicle length exceeding 2 mm were considered germinated. Seeds were monitored for fourteen days at 20 ℃ in the air-conditioning cabinet. The germination habitat was adjusted for 12 hours of daylight and 12 hours of darkness. In the study, it was determined that the differences between the varieties and the averages of different drought levels were statistically significant and it was determined that increasing drought levels prolong the germination period, reduce the germination index and drought tolerance index, and also negatively affect seedling development. As a result of the experiment, it was observed that the Violetta forage pea variety was more tolerant of drought stress than other varieties.
