Between the years 2011 and 2022, the Czech hop varieties Agnus, Rubín, Vital, Gaia and Boomerang were evaluated in terms of their hop yield. The highest hop yield was recorded in Gaia (2.99 kg/plant) and Vital (2.92 kg/plant). Boomerang had the lowest yield (2.11 kg/plant.). The lowest variability of yield was determined in Vital (19.74%) and the highest in Boomerang (33.29%) and Agnus (32.98%). Vital demonstrated the lowest decreasing trend of hop yield over a period of 12 years. Rubín showed the highest decreasing trend.
