This study was carried out at the Experimental Field of Cukurova University in 2015 and 2016 as a double crop growing season. The objective of this study was to determine the seed yield, some agronomic and quality characteristics of some soybean varieties grown as a double crop in Mediterranean Region in Turkey. The experimental design was arranged in a Randomized Complete Block with three replications. The Arisoy, Atakisi, Ataem-7, Umut-2002, Turksoy, Adasoy, Cinsoy, Ilksoy, Bravo, Sa-88, 5.4240, Blaze, Nova, May-5312, Cetinbey, May-5414 and 34A7 varieties (belonging to maturity groups II, III, IV and V) were used as a plant material in this study. Plant and the lowest pod height, pod number per plant, seed yield, 100-seed weight, the oil and protein percentage characteristics were investigated. The seed yield was varied between 3661.2 kg ha(-1) (Cetinbey) and 4430.5 kg ha(-1)(Ilksoy) in a two year average. The differences between the investigated characteristics were found significant except branch number per plant in 2015, 2016 and two years average.
