Can orange fleshed sweet potatoes processing trigger farmers to use quality improved planting materials? Empirical evidence from selected regions in Tanzania
January-March 2021
Production of orange-fleshed sweet potato (OFSP) in Tanzania is constrained by the underutilization of virus-free improved certified planting materials. The sustainable use of these planting materials leads to the constant demand of the planting materials by farmers which can be triggered from viable processing. We determine the viability of processing in the OFSP value chain and its contribution to the uptake of...
