This study evaluated the effect of pollen supplement on honeybees during flower scarcity (2015/16 through 2017/18) at an apiary in Haro Sabu Agricultural Research Center, Kellem Wollega, Western Ethiopia. Three treatments were compared namely: Chickpea (Cicer arietinum), Mung bean (Vigna radiata) and Soya bean (Glycine max), each one with four replication in a by Completely Randomized Design was used. All the feeding treatments were consumed by the bee colonies, and they were more consumed during the dry than the rainy season, but with no significant differences (p<0.05) between the given fed group. The colonies fed supplementary pulses worked harder than those unfed. Therefore, pollen supplementary feeding at flower scarcity maintains the strength of bee colonies for the next natural pollen and nectar flow season.
