Effects of Growing Season and Root Presence on Some Yield Components and Fatty Acid Composition of Sesame in Cukurova Region

Abstract

Sesame is harvested manually in Turkey. The traditional harvesting system which are ripped and bound in small bundles by labor and later dry plants are threshing. This system is being not only increases the cost of sesame, but also leads to a gradual decrease in planting area of sesame in Turkey. In the Turkey has been working on complete mechanization of sesame harvesting and threshing. Till now, the farmers do not prefer to mechanical harvest system because they are considering that the quality of seed are reduce by cutting the roots at the harvest.

The main purpose of the study is to determine the relationship between root presence and seed quality in sesame. For this purpose, some quality parameters were compared to the seeds obtained from rooted and without root plants.

It was carried out randomized complete split plot design, four replicates in Cukurova Region and for two years under main and second crops conditions. In the study, 1000 seed weight, fat-protein ration and fatty acid composition were determined in sesame seeds obtained from plants rooted and without root. As a result, this study found that root presence has no statistically significant effect on palmitic, stearic, oleic, linoleic acid. But, it was determined that root presence was a significant effect on seed weight (P˂0.05). Despite could be determined that the growing season (main and second crop conditional) has statistically significant effect on stearic (p˂0.05) and oleic acids (p˂0.01), could not be determined this effect on palmitic and linoleic acid.
