Peanut is a major source of vegetable oil and protein globally, with seed oil quality known to be affected by moisture and temperature. To address the limited data on peanut chemical composition under Turkish environmental conditions, field trials were conducted across different seasons at the Cukurova University Farm. The research evaluated the oil content and fatty acid profiles of several peanut varieties grown under both main and double cropping systems. Two-year average results showed that total seed oil content ranged from 47.55 to 51.55 per cent in main crops, and from 43.71 to 50.48 per cent in double crops. Across both systems, oleic acid levels varied widely between roughly 39 and 81 per cent. Similarly, linoleic acid concentrations ranged between 1.73 and 36.38 per cent in main cropping, and between 2.66 and 37.72 per cent in double cropping.
Peanuts are an essential oilseed crop, but climatic factors such as moisture and temperature significantly influence their chemical properties. Understanding how seasonal cropping systems affect oil yields and fatty acid composition clarifies the performance of different peanut varieties in Mediterranean environments. This information helps inform agricultural strategies aimed at producing peanut crops with specific nutritional and industrial oil qualities.
This early-stage agronomic research provides comparative data that could help seed breeders and growers select varieties best suited for oil extraction under main or double cropping regimes. High-oleic peanut oils are of interest to food manufacturers seeking stable vegetable oils. However, the abstract reports only experimental field characterisation, meaning industrial processing evaluations and supply chain development would be necessary before these findings reach commercial practice.

Peanut is one of the most important oil and protein producing crops in the world. Quality of peanut seed oil is influenced by temperature and moisture. However, little is known about the chemical composition of peanut grown in environmental conditions of Turkey. Therefore, this study was conducted at the Cukurova University Farm, Turkey as a main and double cropped to determinate oil quality and fatty acid compositions of some peanut varieties in different growing seasons. The results of study indicated that, the oil content (two years average) of peanut varieties ranged from 47.55-51.55% in main cropped and 43.71-50.48% in double cropped growing seasons. Further, the oleic acid content was also varied between 39.80-81.13% and 39.42-81.51% in main and double cropped growing seasons, respectively and the linoleic acid percentage values of peanut varieties ranged from 1.73 to 36.38% in main cropped and from 2.66 to 37.72% in double cropped growing season.
