Determination of yield and yield components of some soybean (Glycine max L.) varieties at high altitudes

This investigation was carried out in Bingol that had 1151 meter altitude in East Gateway Region of Turkey in 2012 and 2014. The study was established according to the randomized block experimenta ldesign with three replication. In this research such as Ataem-7, Yemsoy, Ye？ilsoy, Adasoy, Cinsoy, Blaze, Nova, May 5312, Erensoy, Türksoy, Umut 2002 ve Nazl？can soybean varieties were used as materials. In the all soybean varieties node number, seed number per pod, branche number, pod number, plant height, first fruit height, 1000 seed weight, harvest index, oil rate and seed yield characteristics were investigated. In the experiment; The highest number of nodes was found from Adasoy cultivar with 24.53 number plant-1, the highest fruit height 40.30 cm with Yemsoy, the highest 1000 weight 156.96 g with Umut-2002, the highest yield with 239.10 kg da-1 Ye？ilsoy and highest oil rate content was obtained from Ye？ilsoy with 18.78% in the 2012 growing season. The highest number of nodes was found from Ataem-7 cultivar with 20.33 number plant-1, the highest fruit height 31.23 cm with Ataem-7, the highest 1000 weight 128.18 g with Erensoy, the highest yield with 112.63 kg da-1 Yemsoy and highest oil rate content was obtained from Türksoy with 17.61% in the 2014 growing season
