The agricultural crops grown in the mountain areas are showing considerable decline in productivity. The lack of visit by sufficient insect pollinators in the crop field is supposed to be one of the important factors for such a decline in productivity of the crops. For the production of better quality and yield of seeds, adequate pollination of crop is essential. Since most crops are completely or incapable of pollinating themselves, cross pollination of these flowers by the pollinating insects is indispensable. In Nepal, people living in the mountains regard special value to the buckwheat crops. It is because its input costs are very low, easy to grow even when other crops fail. It is adaptive to adverse climatic condition, well fitted in the sustainable farming system and helps to fulfill the precarious food needs of the hungry people. According to Rajbhandari and Hatley, 1991/92 the yield of buckwheat crop is 600 to 800 kg ha. This indicates that both the production and productivity of this crop needs to be elevated to keep pace with the growing demands of the population residing in the mountain and remote areas. In the present study, the potential of buckwheat crop through mobilization of honeybee colonies has been tried to explore expecting better pollination towards increased fertility and seed yield. The field experimentation will be done at RECAST, Tribhuvan University, Nepal
