Abstract
This study was conducted at the experimental area of the Department of Field Crops, Faculty of Agriculture, Cukurova University as a main crop in 2015. The objective of this study was to determinate the effect of harvesting dates on oil and fatty acid composition of peanut (Arachis hypogaea L.) varieties grown in main cropped condition in Cukurova region. The experimental design was a split plot with three replications. The Halisbey, Sultan, Arioglu-2003, Osmaniye-2005, NC-7, Batem-5025, Flower 22, Flower-32, Flower-36, Brantley and Wilson peanut varieties (Virginia market type) were used as a plant material in this research. The plants were harvested at 149, 156, 163 and 170 days after sowing (DAS). Oil and fatty acids (palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, arachidic acid, behenic acid and lignoceric acid) content and Oleic acid to Linoleic acid ratio (O/L) of peanut varieties were investigated. As a result, the oil percentage of peanut varieties was increased from 47.8% to 50.3% when the harvesting delayed from 149 DAS to 170 DAS. While the palmitic and linoleic acid percentage was decreasing, the stearic and oleic acid percentage was increased when the harvesting delayed from 149 DAS to 170 DAS in peanut varieties. The others fatty acids were not affected by the harvesting time.
