This paper presents the influence of meteorological conditions prevailing in the western part of Poland on the yield of selected blueberry varieties. The research was conducted on a small plantation located in the Przyczyna Górna village, in the Wschowa district of the Lubuskie province. There are five varieties of blueberry: Patriot, Duke, Chandler, Elliott and Bleuecrop. The studied years 2014, 2015, 2016, as the first fruiting years, were presented in relation to the multi-year 2006-2016.
