Abiotic stresses triggered by climate change often damage peanut leaves (Arachis hypogaea L.) during developmental stages, and the effects of this damage on fat and fatty acids are unclear. Thus, this study examined the impact of leaf damage rates on the different growth stages of peanut (Arachis hypogaea L.) grown in the Eastern Mediterranean region of Osmaniye, Türkiye, during the main crop season. The experiment was conducted in a split-split plot design with three replications during 2020 and 2021 vegetation periods. Different yield and quality criteria were studied by placing independent variables, such as varieties (NC 7 and Halisbey) on main plots, growth stages (R1, R2, and R3) on sub-plots, and leaf damage levels (control, 25%, 50%, and 75%) on sub-sub-plots. The highest oil content was obtained in the Halisbey (48.30%±0.32) variety at the R3 stage (48.70%±0.32) and at 75% leaf damage (48.27%±0.21). The highest oleic acid was found in NC 7 variety (52.20%±0.33), at the R3 stage (51.19%±0.61), and %50 leaf damage (50.92%±0.72). The order of leaf damage treatments in terms of linoleic acid was as follows: in control (49.95%±0.31), in 75% leaf damage (50.37±0.60%), in 25% leaf damage (50.57%±0.54), and in 50% leaf damage (50.92%±0.72). As a consequence, it has been determined that the selection of varieties and integrated control against abiotic and biotic stresses are essential to reduce the effects of leaf damage on peanut fat and fatty acids.
