Agronomic and Quality Characteristics of Soybean Different Maturity Groups

Soybean is a crucial legume and vegetable source of protein and oil. Its provide significantly to global food safety and nutrition as a staple diet for people and an essential part of animal feed, helping to meet the world's increasing demand for protein. The aim of the present study is to evaluate the characteristics of soybean varieties in different maturity groups in the ecological condition of Ankara. For this purpose, the soybean cultivars (cvs) İlksoy, Mersoy, Arısoy and Turbo which are in different maturity in groups were used. The study was designed as a randomized block design with tree replications. In the study, the various agronomic and quality characteristics of cultivars such as plant height, first pod height, number of pods, number of branches, thousand-seed weight, seed yield, crude oil and crude protein content were examined. In the study, plant height, number of branches per plant, number of grains per pod, number of pods per plant, thousand seed weight, seed yield, crude oil ratio, crude protein ratio were found to be statistically significant. According to results, the plant height was measured to range between 45.80 cm and 62.77 cm. The number of grains per pod were between 2.1 and 2.6. The thousand-seed weight was determined to range from 136.8 g to 151.0 g. The seed yield of cvs İlksoy, Arısoy and Mersoy was determined 210.39, 208.18 and 179.31 kg da-1 The crude oil content of all cultivars ranged between 14.77% and 16.46% while crude protein content of those was ranged between 38.90% and 40.68%. In conclusion, it was determined that soybean varieties belonging to maturity groups 2 and 3.6 may be suitable for seed yield.
