Brewing industry is interested in raw materials of the best possible technological quality and producers in varieties with the highest possible yield. In order to find out effects of time of sowing (spring, autumn) and weather conditions on yield and technological quality of barley, 11 winter barley varieties and 6 spring barley varieties were tested in the field of the Centre for Agricultural and Technological Research in Zajecar (Serbia, Yugoslavia), in the period between 1987-1989. In the tested period there were both very favourable and unfavourable years for barley growing. According to the results achieved, winter barley varieties showed greater resistance to lodging in relation to spring barley varieties. Winter barley varieties had higher yield than spring barley varieties and their average yield was 6,965 kg/ha. Winter barley varieties had much greater 1000 grain mass (43.02 g) than spring barley varieties (37.94 g), while there was no greater difference between hectolitre masses. Owing to greater 1000 grain mass, winter barley varieties had a greater content of the 1st class grains. Winter barley varieties showed lower protein content (13.94%) than spring barley varieties (14.50%) because their grain was formed in the period of lower temperatures and greater humidity. There were no significant differences in the content of extract.
