The Kenyan government is currently supporting the start-up as well as the growth of youth enterprises, in line with the Medium Term Plan of Vision 2030, by creating a conducive environment and support programmes in order to develop the sector. Despite these efforts, the performance of youth enterprises in Kenya has been miserable. The breadth to which this huge amount of money has influenced the growth and profit margins of these many youth enterprises remains unexplored. Furthermore, there is a lack of enough literature as far as the effect of youth enterprise development fund on the growth of MSEs. This research, therefore, sought to establish the effect of Youth Enterprise Development Fund services on the growth of MSEs in Nyando Constituency. The objectives that guided this study include: to determine the effect of YEDF lending financing services on growth of youth MSEs in Nyando Constituency; to determine the effect of YEDF linkage services with large enterprises on growth of youth MSEs in Nyando Constituency; to establish the effect of YEDF marketing services on growth of youth MSEs locally and internationally in Nyando Constituency and to determine the extent to which YEDF provides Business Development Services to Youth MSEs in Nyando Constituency. A descriptive survey research design was employed.
