Determining Grain Quality (Physical and Chemical) Properties and Nutritional Values in Some Two-Rowed Barley (Hordeum vulgare conv. distichon) Cultivars Grown in Terrestrial Climate Conditions

Barley grain is rich in nutritional value and mineral elements. It is an important cereal crop used human food, malt and feed for animals. This study was conducted to determine some physical and chemical quality characteristics, like thousand-grain and hectoliter weight, protein, moisture, ash, starch, oil, ADF (acid detergent fiber), NDF (neutral detergent fiber) percent, potassium (K), magnesium (Mg), and phosphorus (P) contents of 14 two-rowed barley cultivars (Akar, Burakbey, Tarm-92, Aydanhan & imath;m, Zeynelaga, Keser, Balkan-96, Hilal, Sur 93,Sahin 91, Cumra-2001, Erciyes, Efes-98, Anadolu 98) with a randomized complete block design and three replications for two years during the 2016-2018 growing seasons (wintery) in the terrestrial climate conditions ofSiran-Gumu & scedil;hane (Turkiye) located in the Eastern Black Sea Region. According to the two-year mean results, the thousand-grain weight of the cultivars ranged between 35.74-46.27 g, hectoliter weight 62.03-68.18 kg hl(-1,) protein percent 10.20-14.08%, moisture percent 09.32-09.75%, ash percent 1.99-2.21%, starch percent 57.22-61.77%, oil percent 1.52-2.02%, ADF percent 5.72-7.82%, NDF percent 21.19-23.20%, K content 0.657-0.742%, Mg content 0.156-0.191% and P content 0.401-0.430%. A positive and significant correlation was determined between thousand-grain weight and hectoliter weight, starch, oil, ADF, NDF, K, Mg, and P percent. Aydanhan & imath;m, Cumra-2001, Akar, Efes-98 and Balkan-96 cultivars were the prominent cultivars in terms of Physical and chemical quality characteristics and mineral substance values were evaluated in the study. Therefore, it is seen that these cultivars can be recommended to farmers who grow forage barley in the region.
