This study aimed to assess the presence of various ratios of black and white hulled grains in barley grain lots and mixture impacts on marketing prices. The study was carried out in the Sanlıurfa commodity market in the autumn of 2005 in Sanlıurfa and Diyarbakir in 2015 and Sanliurfa, Adıyaman and Gaziantep local commodity markets in 2017. The seven barley grain samples were prepared (100% White [W], 10% Black [B]+90% White [W], 20%B+80%W, 30%B+70%W, 40%B+60%W, 50%B+50%W and 100% Black) and presented to four randomly selected grain purchasers in all commodity markets and marketing price offers were scored. Increasing ratios of black-hulled barley (BHB) reduced marketing price gradually in 2005. In 2015, marketing prices were 0.337 US$ kg^-1 for white and 0.365 US$ kg^-1 for black in Sanliurfa and 0.334 US$ kg^-1 for white and 0.352 US$ kg^-1 for black barley in Diyarbakir. In 2017, except for Adıyaman, marketing price offers were in favour of BHB and it received 0.37 US$ kg^-1 and 0.321 US$ kg^-1 marketing price offers in Gaziantep and Diyarbakır, respectively. In 2017, WHB marketing prices were 0.325 US$ kg^-1 and 0.315 US$ kg^-1 in Gaziantep and Diyarbakır locations, respectively.

It was concluded that, except for Adıyaman, barley marketing prices traditionally in favour of white hulled barley turned out to be in favour of black type in a decade in south eastern Anatolia.
