THE EFFECT OF HARVESTING DATES ON SOME AGRONOMIC AND QUALITY CHARACTERISTICS OF PEANUT (Arachis hypogaea L.) VARIETIES GROWN AS A MAIN CROP IN MEDITERRANEAN REGION (TURKEY)

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 and 2016. The objective of this study was to determinate the effect of harvesting dates on some agronomic and quality characteristics of peanut (Arachis hypogaea L.) varieties grown as a main crop in Mediterranean region (Turkey). The experimental design was a split plot with three replications.

The Determination of Fatty Acids Composition and Oil Quality Factors of Some Peanut Varieties Having Different Market Types at Different Harvesting Times in Main and Double Crop Growing Seasons in Mediterranean Region

“…Significant differences for palmitic, stearic and lignoceric acids percentage among the cultivars are attributable to the genetic makeup and place of their origin (Hassan et al, 2005). These results are in agreement with the findings of Dwivedi et al (2000), Anderson and Gorbet (2002), Ozcan and Seven (2003), Hassan et al (2005), Gulluoglu et al (2016), Sogut et al (2016) and Arioglu et al (2018),…”

“…The reason for the differences between the varieties for the iodine value was them having different oleic and linoleic acids content. These results are in agreement with the findings of How and Young (1983), Raheja et al (1987), Hashim et al (1993), Hinds (1995), Andersen and Gorbet (2002), Chaiyadee et al (2013), Chamberline et al (2014), Chowdhury et al (2015), Gulluoglu et al (2016) and Arioglu et al (2018) were indicated similar results.…”

“…Caliskan et al (2008) reported that while the oil percentage was 49.5% when the seed harvested 120 DAS, it was increased to 52.6% harvesting time was delayed to 160 DAS. Arioglu et al (2018) reported that while the oil percentage was 47.4% when the seed harvested 149 DAS, it increased to 49.8% harvesting time was delayed to 170 DAS in main crop growing season. The oil content of the varieties was higher in double crop growing season than main crop growing season in a two year average.…”

“…According to a two-year average, interaction between the variety and harvesting time for the oleic and linoleic acids percentage was statistically significant in both growing seasons. Andersen and Gorbet (2002), Gulluoglu et al (2016) and Arioglu et al (2018) reported that seed maturity can also influence the fatty acid composition of peanut. The actual impact of seed maturity is dependent on genotype, climatic conditions, and genotype/climate interactions.…”

“…Gulluoglu et al (2016) reported that the oleic and linoleic acids percentage of peanut varieties were varied between 51.54-54.94% and 24.65-26.78%, respectively at different harvesting times in main crop growing seasons in Cukurova region. Arioglu et al (2018) reported that the oleic and linoleic acids percentage of peanut varieties were varied between 53.69-57.38% and 20.74-23.73%, respectively at different harvesting times in main crop growing seasons in Mediterranean region. Gulluoglu et al (2016) and Arioglu et al (2018) indicated that the oleic acid percentage was increased and linoleic acid was decreased when the harvesting times delayed.…”
