ENVIRONMENTAL EFFECTS ON GRAIN YIELDS AND QUALITY PARAMETERS OF WINTER BARLEY OF BEER IN THE REPUBLIC OF KOSOVO

The object of this paper is the study of environmental effects on grain yields and quality parameters of winter barley beer in the Republic of Kosovo. In analyzing the chemical composition of several parameters that affect the quality of beer have a total of five barley cultivars: Bingo, Zlatko, Vannesa, Esterel and Rex as comparative (standard). Environmental effects of planting barley cultivars in the Dukagjini area and area of Kosovo is based on a study that determines the influence of climatic factors, temperature and moisture, the quality of barley for beer production. Analysis of chemical composition of several parameters that affect the quality of beer were conducted in two regions of Kosovo(in Arbnesh in research farm of the agricultural institute of Kosovo, Peja ? Dukagjin Plain, and Pestova ? Kosovo Plain, privately owned company " Pestova". Experiments were set according to the method of randomized blocks in three repetitions. Area of each experimental plot was 10 m2. In the laboratory at the Agricultural Institute of Kosovo, and close laboratory brewery in Pec were analyzed: the content of protein (%), weight (1000 seeds in grams), hectoliters weight (kg), humidity (%), yield (kg/ha), starch, color, aroma, impurity. Results obtained showed that there were significant statistical differences at different levels to investigate the features of all the parameters involved in plots compared with the standard (Rex) and between localities.
