The knowledge of the protein content of pollen in the area of beekeeping is important about the bee colonies. Pollen collected by honey bees has different protein content at different seasons of the year and for each year, which depend of distribution of the plants and the climate condition. The statistical analysis of the data proved a difference in the protein content in pollen between the summer, spring and autumn. In the study area the percentage of protein content in the examined mixed pollen samples has different value: in 2012 ranged from 13.9% to 25%, in 2013 it ranged from 15.6% to 25.1% and for 2014 it was from 18.4% to 27.8% and the average value is 21%. The study results showed that the protein content of mixed pollen varied for each reporting period of each month and for each single month. The reason of the differences probably came from the dynamic change of the ecological factors and the urban environment, which influenced flowering of the plants. The florospecialization of the honey bees also play major role.
