Determination of yield and yield components of some soybean (Glycine max. L) varieties in the conditions of eastern transition region

This study, which was carried out to determine yield and yield components of some soybean varieties in the ecological conditions of Bingol, was established and conducted with 3 replicates according to the Randomized Block Experimental Design in a rented field, located in the land base in the province of Bingol in 2012. In this study Ataem 7, Adasoy, Nazlıcan, Turksoy, Yemsoy, Yeşilsoy, Blaze, Nova, Erensoy, Cinsoy, Umut 2002 and, May 5312 types were used as material. The node number, seed number per pod, the number of branches, pods per plant, plant height, first fruit height, thousand-grain weight per plant, yield, oil content, harvest index, per hectare yield and relationships among traits were examined in the types. In conclusion, in terms of number of nodes Adasoy (24.53 units / plants); in terms of number of seeds per pod Nova and May, 5312 (2.78 units /pods); in terms of number of branches Nazlican (3.80 unit / plant); in terms of number of pods Yeşilsoy (72.10 units / plants); in terms of plant height Adasoy (126.07 cm); in terms of first fruit size Yemsoy (40.30 cm); in terms of thousand kernel weight Umut 2002 (15.70 g); in terms of yield per plant Cinsoy (15.72 g / plant); in terms of fat content Yeşilsoy (18.78%), and Adasoy (17.85%); in terms of harvest index Cinsoy (55.93%) and in terms of yield per hectare Yeşilsoy (239.10 kg / ha) types were found to have high values and, Umut 2002 (128.23 kg / ha) type yielded the lowest results. In addition, a positive and significant correlation was found between plant height and number of nodal and number of pods; and a negative and significant correlation was identified between the number of seeds per pod and the number of branches.
