      abstract = {Hidden hunger, resulting from micronutrient deficiency, is  a major problem in developing
countries. Vitamin A is one  of the micronutrients that are widely deficient in diets of  many rural
households. Biofortified staples that are rich  in beta carotene, a precursor for vitamin A, such as
Orange  Fleshed Sweetpotato (OFSP) can contribute to solving this  problem. Recent efforts have
therefore focused on  sensitizing farmers about the benefits of OSFP while at the  same time
supplying highly subsidized quality (i.e., pest  and diseases free) OFSP planting materials (i.e.,
vines),  usually fee or at heavily subsidized prices. This study  uses seemingly unrelated
regression technique and data from  481 farmers to assess the demand for quality OFSP vines  and
the factors affecting the demand for such vines. It  finds high willingness to pay for quality OFSP
vines shown  by the high willingness to pay. Demand for quality vines is  affected by number of
children, age, tastes, preferences,  yield and Income. The study concludes that demand for  quality
OFSP vines is high, but still lower than for  white-fleshed varieties. It discusses implications of
the  findings.},
