Özet:

Yield and quality performances of 27 soybean cultivars were evaluated in two years field experiment between 2015 and 2016 at the Experimental Farm of Faculty of Agricultural Sciences and Technologies, Nigde Omer Halisdemir University, Nigde, located in the Central Anatolia Region. The field experiments were laid out in the randomized complete block design with three replications in each year. The main phenological stages of development such as time to emergence, flowering, time to pod formation and time to maturity were determined as calendar days. Plant height, the first pod height, numbers of branch, pod and seed per plant, number of seed per pod, 100-seed weight, protein content, oil content and seed yield per decar were determined as yield and quality parameters. The results of two-year study revealed that the soybean cultivars differed significantly for all characters studied under Nigde conditions. It was also observed that yield and quality performances of cultivars fluctuated in years. Average seed yield values of cultivars were ranged from 135.2 kg/da-1 (Inton-I. maturity group) to 295.8 kg/da-1 (Adasoy-IV maturity group) in 2015 and 2016. In two years mean, the cultivars Adasoy, Sa-88 and Nova were determined as the most promising genotypes for main crop production in Nigde conditions.
