A Research on Expansion and Adoption of the Wheat (Triticum aestivum L.)Varieties Certified as Esperia and Tosunbey: The Example of Polatlı District in Ankara

Abstract

The aim of this study is to determine which wheat varieties developed by public and private sector extension organizations are preferred by producers. In addition, it has been determined which wheat varieties are preferred due to their characteristics. The study was conducted in Ankara-Polatli district. In 2015, Polatli district was chosen because of the widespread use of wheat varieties developed by public and private sector extension. Tosunbey wheat variety was used in public sector and Esperiye wheat variety was used in private sector extension. The data in the farmer registration system were used to identify the producers using both wheat varieties. Stratified sampling method was used to determine the sample volume. According to this method, the sample volume was determined as 74 producers. In June-August 2015, face-to-face interviews were conducted with producers to collect data. Chi-Square test was used to compare the relationships between the data obtained. According to the research findings; There was a statistically significant relationship between producer's wheat type preference and variables such as residence, irrigable land size and membership to agricultural unions (P<0.05). It was determined that high prices and advance payments given to the product were the main factors affecting the choice of wheat varieties. It has been concluded that private sector extension is more effective in adopting wheat varieties than public sector extension.
