Abstract
The paper analyzes the effect of a promising additive (BAA) fulvic acid on the reproductive function of queen bees and the productivity of bee layers. A single dose of carbohydrate supplementation (40% sucrase) was 200 ml per family. A total of 12 feedings were carried out with an interval of three days. The effect of the drug on the reproductive function of queen bees was determined by counting the number of printed brood using a grid frame every 12 days. As a result of the research, a positive effect of fulvic acid on the reproductive function of queen bees was established. When using fulvic acid as a spring feeding of bee colonies, a significant increase was established on average by 22.5% over two years of research, and the honey productivity of bee layers increased by 17.7%.
