Agronomic and quality properties and mineral contents of mung bean [Vigna radiata (L.) Wilczek] genotypes grown at different altitudes

Vigna radiate L. (Mung bean) is an edible leguminous plant that has adapted to different environmental conditions and possesses many varieties and local formas. Agronomic traits and nutrient compositions change depending on genotype and environmental conditions. In the present study, changes in agronomic properties, qualitative properties, and nutrient composition of 7 mung bean genotypes grown at different altitudes (L1: 1050 m, L2: 314 m) in two different locations [Isparta (L1) and Mersin (L2)] were investigated. It was found that there were significant differences between genotypes in both locations in terms of all characteristics examined in the study. In the study, it was found that the L2 location was superior in terms of agronomic characteristics. Water absorption capacity and swelling index were higher in the L2 location, while fat content, protein ratio, ash content, and carbohydrate content were higher in the L1 location. In terms of mineral element content, phosphorus, magnesium, and iron were higher in the L1 location, whereas calcium, copper, and zinc were higher in the L2 location, and potassium and manganese were not affected by locations. Examining both locations, the G2 genotype was superior in terms of agronomic characteristics, the G6 genotype was superior in terms of quality characteristics, and the G5 genotype was superior in terms of mineral content characteristics compared to other genotypes. Also, it was found that growing mung beans at low altitudes was more advantageous in terms of yield and yield components. However, it was found that the quality and nutrient composition of mung beans grown at higher altitudes were higher.
