Özet:

In this study investigated the seed yield, oil rate, protein rate, yield and yield components of seven different soybean varieties that were from different maturation groups and grown under conditions. The trial was carried out in a farm land in Kurtuluş Village of İdil Town, Şırnak, Turkey in 2018 crop season. The study was designed in accordance with the randomized block design and carried out in three replications. In the study, important properties such as seed yield, oil content, crude oil content and yield components were investigated. The results showed that the seed yield values of the investigated soybean genotypes  ranged from 2617.0 kg ha-1 to 3762.5 kg ha-1  and the highest seed yield values were obtained with the Asya (3762.5 kg ha-1 ), Adasoy (3330.2 kg ha-1 ) and Türksoy (3317.4 kg ha-1 ) varieties. The oil contents of the soybean genotypes  varied between 19.90% and 21.23% and protein contents varied between 32.59% and 35.44%. The Adasoy (35.44%) variety had the highest protein content. The results revealed that the genotypes can be successfully grown under second crop conditions in terms of growing time and yield.
