Walnuts (Juglans regia L.) are a good source of dietary minerals and contain significant amounts of potassium, phosphorus, magnesium and iron. In Turkey, walnut orchards are found in the coruh Valley and are generally composed of local varieties. Since chemical and physical properties of walnuts are very important in determining their quality, in this study, nut and kernel characteristics, fatty acid composition and phenolic composition were determined for 26 walnut genotypes collected from the valley. Total fat content was found to be between 53.75% and 71.43%, while the crude protein amount ranged from 10.21% to 20.71%. Total carbohydrates were calculated between 14.31-27.52% and ash content was found to be between 1.64% and 3.32%. The oleic acid content and linoleic acid content ranged from 18.34 to 25.58% and 37.09% to 87.51%, respectively. The linolenic acid content was determined between 5.52% and 11.03%. Our study showed that, differences in phenolic component, crude protein and fatty acid content of walnuts were caused by different growing conditions. Genotypes have a rich and stable structure in terms of fruit quality parameters, minerals, organic acids, phenolic composition, antioxidant and fatty acids amounts and amino acids. In other words, these characteristics did not show much variation in genotypes grown in the Valley. However, there was a great variation in hormone levels among genotypes. In terms of the parameters examined, GN2, GNI, ((NIS, GN24, GN25 and GN26 genotypes were determined as rich and stable genotypes.

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.
