Zusammenfassung:Research in the Eastern Mediterranean Transition Region of Türkiye has demonstrated that plant density (planting pattern) impact yield of peanut (Arachis hypogaea L.) cultivars differentially. It is suspected that interactions of planting pattern and cultivar could also impact oil quality and fatty acid composition when grown in this region. This topic has not been addressed in the country; therefore, the objective of this research was to determine if planting pattern can affect those variables. The study was conducted in 2020 and 2021 in the zone of Osmaniye to determine total oil content of kernels, and contents of oleic acid, palmitic acid, arachidonic acid, linoleic acid, stearic acid, and lignoceric acid, as well as iodine value and oleic/linoleic ratio for the cultivars Halisbey, Rigel, Aysehanım, NC 7, and Masal. The planting pattern consisted in either a single row pattern with rows spaced 70 cm apart (95.000 plants·ha-1), or a twin row pattern with rows spaced 20 cm apart on 90 cm centers with an intra-row distance of 15 cm (148.000 plants·ha-1). Plant response was in most instances different regardless of plant populations. It is concluded that no differences in total oil content were noted when comparing cultivars established at various combinations of planting pattern and plant population, although differences existed for all individual fatty acids. For oil content, there were notable differences among the cultivars. Estudios realizados en la región del Mediterráneo oriental de Turquía han demostrado que la densidad de plantas (método de siembra) afecta el rendimiento de los cultivares de maní (Arachis hipogaea L.) de manera diferencial. Se estima que las interacciones entre la densidad de plantas y el cultivar también podrían afectar la calidad del aceite y la composición de ácidos grasos. Este tema aún no ha sido abordado en el país por lo que el objetivo de esta investigación fue determinar si la densidad de plantación puede afectar dichas variables. Se realizaron investigaciones en 2020 y 2021 en la zona de Osmaniye para determinar el contenido total de aceite de las semillas y los contenidos de ácido oleico, ácido palmítico, ácido araquidónico, ácido linoleico, ácido esteárico, ácido lignocérico, así como el valor de yodo y la relación oleico/linoleico en los cultivares Halisbey, Rigel, Aysehanım, NC 7 y Masal. Se emplearon dos patrones de siembra: hilera única con hileras separadas 70 cm (95.000 plantas·ha-1 ), y un patrón de siembra en h
