Changes in Mineral Composition of Different Peanut Varieties Exposed to Leaf Damage

This study was conducted in the Eastern Mediterranean conditions in 2020 and 2021 to determine the effect of different leaf damage (LD) ratios (0, 25%, 50%, and 75%) applied at different developmental stages (flowering, gynophore formation, and pod formation) of two different peanut cultivars (NC 7 and Halisbey) on some macro and micronutrients. In the study, the main plots consisted of cultivars (NC 7 and Halisbey), subplots comprised of application stage (R1, R2, R3) and sub-sub-plots consisted of leaf losses ratios (0, 25%, 50%, and 75%). In the study, the highest content of K, Fe, Cu, Mn, and Na elements was found in 75% LD treatment while the control group was found to be the lowest. At the same time, in 75% LD treatment, it was found that the Cu, Mn, Na and Li element content of the seed was the highest and the control group was the lowest. It was observed that as the leaf damage rate increased in peanuts, the K, Fe, Cu, Mn and Na element values in the leaf and the Mn, Na and Li element values in the seed increased.
