摘要：When the natural pollinator’s declines, beekeeping can contribute to the pollination services, assuring crop yields, and can also be used to strengthen the livelihoods through commercialization to increase economic revenue. A farmers’ survey and field experiment were conducted on 2011 to assess the economics of beekeeping as pollination management practices adopted by the farmers of Chitwan district, Nepal. Samples of 75 respondents from the list of beekeeper farmers of Chitwan district were selected randomly. Information was obtained from individual respondents through a pretested questionnaire and group discussion. Furthermore, to assess the benefit of bee pollination 15 experimental plots were selected to see the effect of bee pollination on mustard crop yield. From the study, the gross income (rupees/hives), productivity (rupees/man-day), average cost (rupees/hives), and gross benefit (rupees/hives) as a result of keeping bees were found to be 4475.23, 1506.30, 2526.66, and 1948.57, respectively. The benefit–cost ratio of beekeeping was found to be significantly higher, at 1.8. The contribution of the bee pollination on the mustard crop production was found significantly higher than that on the mustard production without the insect pollination. This research finding will provide the new ways of thinking on the relationship between beekeeping and their importance on the crop production. The pollination shortage due to pollinator declines can be mitigated through the beekeeping which helps to uplift the sustainable livelihoods of the farmers through income generation.
