The experiment was carried out on 6 groups of 5 colonies. These groups are syrup (S), syrup + Urtica dioica (SU), Syrup + Melissa officinalis (SM), Syrup + Hypericum perforatum (SH), Syrup + Achillea millefolium (SA) and syrup + Thymus serpyllum (ST). As a result of the research, the sealed brood area data were determined as 3013.24±1939.26, 3107.00±2060.42, 3270.81±2194.80, 3091.20±1962.69, 3273.90±2095.49 and 3613.06±2348.27 cm2 in S, SU, SM, SH, SA, ST groups, respectively. When we compare the honey yields of the experimental groups, according to group S, SU increased by 18.48%, SM 43.10%, SH 16.04%, SA 27.35% and ST 53.86%. Therefore, syrup + medicinal and aromatic plant extract mixture given to honey bee colonies may have a positive effect on colony development and honey yield. © 2020 Bursa Uludag University.
