This study includes the vineyard farms which apply and do not apply good agricultural practices in Thrace Region. The basic purpose of this study is the economical comparison of the farms applying and not applying good agricultural practices. The 27 grape producers who applied good agricultural practices were interviewed and data were gathered by using questionnaire method in Kırklareli, Edirne and Tekirdağ provinces. In the same provinces, the same survey was also conducted with the same number of producers which do not apply good agricultural practices. In Thrace Region, the one kg grape production cost was calculated 1.12 TL in the farms which applied good agriculture while it was calculated 1.14 TL at the farms which did not apply the good agriculture. Total production cost, gross production value, gross profit, net profit and relative profit were determined to be respectively as 1341.56 TL, 1825 TL, 1034.85TL, 483.45 TL and 1.36 in the farms applying good agricultural practices.
