“…Among food crops, sweet potato has the highest edible energy per hectare per day [12] and it is a primary staple crop (>80 kg/capita/year production) in densely-populated Rwanda, Burundi, Malawi, and parts of Uganda. In other parts of East and Southern Africa, it is a secondary staple (15-60 kg/capita/year), while in West Africa, sweet potato roots are often consumed as a snack or breakfast food (<10 kg/capita/year).Consumption of sweet potato leaves varies widely, with leaves being considered animal feed (crude protein content 68 and 131g/ kg dry matter [13]) in Kenya and Uganda and human leaf consumption dominating root consumption in Liberia and Sierra Leone.…”

In sub-Saharan Africa, more than 40% of children under five years of age suffer from vitamin A deficiency. Among several interventions in place to address vitamin A deficiency is biofortification, breeding vitamin A into key staple crops. Staple crops biofortified with beta-carotene, the precursor to vitamin A, are orange in color. Given the natural occurrence of high levels of beta-carotene in many sweet potato varieties, breeding progress for biofortified orange sweet potato (OSP) has been much faster than for the other vitamin A enhanced staples. Nearly 3 million households have been reached with OSP. This paper reviews key factors influencing the uptake of OSP, the breeding investment, five key delivery approaches that have been tested in the region and efforts to broaden government and other stakeholder engagement.

“…Industrial uses such as the production of starch, alcohol, and partial flour substitute are further utilization options that can be explored in Ghana. Another option is sweet potato fodder and silage for livestock feeding, which has high protein and digestibility values [7,8]. …”

“…Even at low yields of about 6 t/ha, just 500 m 2 of land can generate the annual requirement of vitamin A for a family of five. In addition, it is a remedial crop for crop-livestock farmers because of its high root and fodder productivity with minimal external inputs [7]. For smallholder crop-livestock farmers as well, sweet potato forage yields command additional importance [8].…”

Sweet potato has gained prominence due to its ability to adapt to wide production ecologies and yield response to minimal external inputs. Orange-fleshed cultivars in particular have immense potential to improve household income and nutrition in sub-Saharan Africa. However, the sweet potato value chain (SPVC) is not well-developed in many producing countries. The study was conducted in two regions to characterize the production operations as well as identify opportunities to propel the SPVC in Northern Ghana. Data were collected using mixed methods including structured questionnaires via face-to-face interviews. Analysis of strengths, weaknesses, opportunities, and threats (SWOT) was conducted at multistakeholder platforms with different actors. Gross margin profit and benefit-cost ratios were determined by using six cost variables. Overall, the industry was largely a fresh produce market, targeting food vendors, processors, and direct selling to wholesalers, retailers, and household consumers. The SWOT analysis revealed wide-ranging opportunities including favourable production ecologies, processing options, and insatiable local and international markets. The institutional actors need to network the primary actors to synergistically operate with a collective profit motive. The most prioritized production constraints such as access to seed, cost of chemical fertilizer, short shelf-life, field pests and diseases, and declining soil fertility should be addressed.

“…These cultivars should be able to develop the harvesting technology, the vines, and by periodically they are throughout the growing system without lowering the yield of storage root that can harvest. The use of dual-purpose sweet potato has been evaluated at some areas (Larbi et al, 2007;Peters, 2008;Etelä et al, 2008;Claessens et al, 2008;Kaya and Yildirim, 2011;Etelä and Kalio, 2011;and Ahmed et al, 2012). Those findings can be adapted to sweet potato development for farming systems in Indonesia in line with the agriculture concept of sustainable bio-industry.…”

“…The management system could utilize the sweet potato's ability to regenerate by continually or sporadically harvesting the vines throughout the growing season before finally harvesting the roots. Many researchers have studied sweet potato used for dual-purpose, such as Larbi et al, (2007), Peters (2008), Etela et al, (2008), Claessens et al, (2008), Kaya and Yildirim (2011), Kalio (2011), andAhmed et al, (2012). Those findings are correlated one another in using sweet potato forage to substitute animal fodder grass in croplivestock system.…”

This study aimed to classify the types of sweet potato based on the ratio of total dry matter of roots to vine (R/V) in order to make the option available in integrating the crop-livestock systems. Seventeen sweet potato cultivars were planted in Randomized Complete Block Design with three replications applied at two locations, Malang and Blitar. Each cultivar planted in plot measures 2.5 m x 5 m in Malang and 3.0 m x 5 m in Blitar, and each consists of four rows with a spacing of 25 cm in rows. All cultivars gave a dose of 250 kg NPK fertilizer (15-15-15)/ha twice, one-third of dose given at planting and the remainder in a month after planting. Plants were harvested at four months after planting. Fresh weight and dry weight of storage root, fresh weight and dry weight of vines, harvest index, and the ratio R/V are determined. There was different performance of 17 cultivars planted at two locations. Cultivars planted in Malang were classified into four types, namely forage, which consists of three cultivars among 17 cultivars, low dual-purpose (3 cultivars), high dual-purpose (7 cultivars), and low root production (4 cultivars); while cultivars planted in Blitar turned into the forage type.
