Abstract
The objective of this research is to determine the use of production factors in 3 different types of sunflower production with
respect to orobanche resistance in the agricultural enterprises in Thrace Region which is located at European continent of
Turkey. The data used in this research have been obtained through questionnaire technique from 571 agricultural enterprises
which were determined by Stratified Random Sampling Method in 2009. It has been reached to the highest yield by 189.30
kg da-1 and the highest gross profit by 37.91 US$ da-1 in the production of sunflower, resistant to orobanche. In the research, it
has been determined that the rate of soil testing among the sunflower producers is considerably low and almost the whole of
the production has been made under rainfed conditions. As a result of the research, it has been concluded that orobanche
resistant sunflower, which has higher water productivity than other cultivars by 367.13 g m3
, will have a higher proportion
in the sunflower cultivation areas in future because of its higher contribution to producer welfare.
