SOME SOYBEAN [Glycine max. L. (Merill)] VARIETIES DETERMINATION OF CULTIVATION POSSIBILITIES OF AS MAIN CROP

This research was carried out at Batman University West Raman experimental area with 3 replications in order to determine the yield and yield components of some soybean varieties as the main crop under Batman conditions in the 2018 production year. In the study, 7 different soybean varieties (Umut-2002, Nova, Bravo, Asya, Ataem, Atakişi, Blaze) were used as plant materials. In the study, plant height, number of branches, first pod height, number of pods per plant, yield per decare and oil content were investigated. As a result of the study, the plant height is 64.90-72.47 cm, the number of branches is 4.83-9.23 pieces/plant, the first pod height is 10.70-15.20 cm, the number of pods per plant is 31.27- 49.23 pieces, the seed yield was determined as 244.05-554.44 kg/da and the oil content was between 17.82-24.83%. In addition, it was determined that the results of the heat map clustering, PCA and DARwin plots and the grouping of the relationships between cultivars, traits and cultivar*traits were confirmed
