Abstract: This study was carried out to investigate the relationship between colony strength and each of stored pollen, worker brood rearing, colony population density and honey production. The areas of stored pollen and worker sealed brood, colony population size and honey yield were significantly (p<0.001) higher in the strong than the weak colonies. The strong colonies produced honey 286.80 and 291.67% more than the weak colonies during clover and sidir season, respectively with an average increase of 289.24%. It can be recommended from the research findings to unite the weak colonies to be strong for obtaining high rates of stored pollen and brood production and high honey yield.
