DIFFERENT LAND USE INFLUENCES ON AMINO ACID, ORGANIC ACID, HORMONE AND MINERAL NUTRIENT CONTENTS OF DRY BEANS

Dry bean (Phaseolus vulgaris L.) is a widely grown and important food legume which is a major source of mineral nutrition. The present study digs in determining differences in nutrients, organic-amino acid and hormone concentrations of Ispir bean genotypes under different land use conditions. The study sites (32 locations) were identified according to the stratified sampling method in the Ispir district, Erzurum, Turkey, under consideration of bean-cultivated lands and the number of villages. The seed weights were higher for genotype no. 4 (137.5 g) than for genotype no. 14 (131.5 g) and following by all other genotypes. Moreover, values for crude protein content were significantly higher for genotype no. 14 (263.1 g/kg) in comparison to genotype no. 4 (256.9 g/kg) and other genotypes. Therefore, it is concluded that land use impacts seed weight, nutrient, crude protein, amino acid, organic acid and hormone contents of Ispir dry bean. Land use can result economic improvements in crop yields and yield components. Dry bean seed weights were impacted by other crop yield components such as amino acid, organic acid and hormone contents of dry bean.
