The implication of the net return on investment figures is that the wholesalers and retailers respectively return 0.68 kobo and 0.89 kobo for every 1 Naira invested in the business. Findings also indicated marketing efficiency levels of 59.6% for wholesalers and 52.6% for retailers implying that the retailers are more efficient in the marketing of sweet potato than the wholesalers. Findings on the constraints shows that seasonality of the product, high cost of transportation and rioting militated against sweet potato marketing on the wholesale whereas rioting and inadequate storage facility were perceived at the retail levels. Modern storage facilities and good road transport systems should be made available so that the volume of trade of marketers should increase for optimum profit
