“…This might be because most cooperative societies in the rural areas are not aware of the nutritive value of the crop and as such do not encourage their members to produce it. This finding is consistent with the findings of Kaguongo et al (2012) where knowledge on value addition and nutritional benefit and having children not older than five years of age are said to be the major factors that influences the intensity of adoption of OFSP.…”

In rural Nigeria, most households cannot afford food products rich in vitamin A which gave rise to the introduction of bio-fortified agricultural produces. One of these is the Orange Fleshed Sweet Potatoes (OFSP). Although introduced about six years ago, empirical evidence as regards the actual level of adoption as well as its effect on their productivity remains relatively scarce. The analysis was built on a field survey of 183 smallholders in Kwara State, Nigeria conducted in the year 2016. Tobit model and the Heckman’s two stage models were used to model the determinants the intensity of cultivation and the effect of OFSP’s cultivation on the income of the smallholders. Results indicate that almost 87% of the smallholders sampled were into the cultivation of OFSP with 56% of them cultivating it solely for family consumption and its nutritional value. Also, 44% of them put less than half a hectare of their farmland to the cultivation of OFSP. The result showed that aged smallholders, members of cooperative groups and those who cultivate OFSP solely have a smaller proportion of their farmland cultivated to OFSP. Similarly, the age of the smallholders, household size, years of schooling, cost of production were the factors that significantly influence the cultivation OFSP on the income of the smallholders. The policy implication of this is that the potentials of OFSP have to be promoted particularly among the rural smallholders most especially through the existing cooperative groups. This can either be through organized seminars or specifically through demonstration plots.

“…2); so it is likely that the farmers of this class showed a particular interest in the size of the roots because this criterion is more in demand on the market of this area. Kaguongo et al (2012) reported similar results in his study highlighting that the origin of the farmer as well as the level of commercialization of a variety influences its adoption. For Doussoh et al (2017), high commercial value was one of the important selection criteria for sweet potato varieties intended for production in Benin.…”

“…The specific criteria for selection can vary considerably depending on the country and the production locations and regions. For example, in drought-prone areas, farmers may prefer sweet potato varieties with high yield potential and short maturity periods (Ilukor et al, 2014; Kaguongo et al, 2012). In contrast, in regions where sweet potato is intercropped with other crops, farmers may choose varieties with longer maturity periods and lower yield potential like the white flesh sweet potato (Kapinga et al, 2003).…”

Summary Integrating farmers’ preferences into the breeding and dissemination of new genotypes is a effective approach to enhance their successful adoption by farmers. In the case of sweet potato, a staple crop in many parts of West Africa, there is a need for more research on the selection criteria used by farmers when choosing which varieties to grow. This study aims to highlight farmers’ selection criteria for sweet potato varieties in the main production areas in Benin. A total of 480 farmers from the top three sweet potato production areas were surveyed. The relative importance of various traits for sweet potato farmers was evaluated using best-worst scaling methods. Latent class analysis was applied to find groups of farmers with similar preferences. Best-Worst Scaling analysis revealed that high root yield, root size, marketability, and early maturing were the most important variety selection criteria. Latent class analysis revealed three farmers’ groups referred to as ‘Yield potential’, ‘Market value’, and ‘Plant resilience’ classes. ‘Yield potential’ farmers were more likely to be from Atlantique and Alibori departments; they significantly committed more acreage to sweet potato production. The ‘Market value’ farmers highlighted the variety of root size and commercial value as the main selection criteria and consisted of farmers with primary education levels from the Ouémé department. ‘Plant resilience’ refers to a group of Alibori farmers who prioritize environmental issues and primarily grow sweet potatoes for self-consumption. Our findings shed light on farmers’ preferences and suggested that heterogeneity in sweet potato selection criteria was highly influenced by various socio-economic factors and location.

“…Due to the many positive aspects related to agriculture, nutritional security and food security are resulted in intensified research on OFSP in present decade to augment its production and consumption in different countries. The OFSP possesses the characteristic of attractive sweet taste and eye-pleasing yellow to orange color to children in comparison with white-fleshed sweet potato (WFSP; Kaguongo, 2012); hence, OFSP has reported potential role to tackle calorific and VAD malnutrition problems of children in targeted communities.…”

A wide variety of the roots and tubers plays a major role in human diet, animal feed, and industrial raw materials. Sweet potatoes (SPs) play an immense role in human diet and considered as second staple food in developed and underdeveloped countries. Moreover, SP production and management need low inputs compared to the other staple crops. The color of SP flesh varied from white, yellow, purple, and orange. Scientific studies reported the diversity in SP flesh color and connection with nutritional and sensory acceptability. Among all, orange‐fleshed sweet potato (OFSP) has been attracting food technologists and nutritionists due to its high content of carotenoids and pleasant sensory characteristics with color. Researchers reported the encouraging health effects of OFSP intervention into the staple food currently practicing in countries such as Uganda, Mozambique, Kenya, and Nigeria. Scientific reviews on the OFSP nutritional composition and role in vitamin A management (VAM) are hardly available in the published literature. So, this review is conducted to address the detailed nutritional composition (proximate, mineral, carotenoids, vitamins, phenolic acids, and antioxidant properties), role in vitamin A deficiency (VAD) management, and different food products that can be made from OFSP.
