Presented by WorldFish scientist Sonia Allauca recently at the 'Value Chain Study Results Presentation and Strategy Formulation', held at the BRAC Center, Dhaka, Bangladesh, on the 12th and 13th of November. It was later presented at the 'Sweetpotato Value Chain Strategy as a core component of nutrition promotion and women enterprise development', which was held from the 11th to the 13th of February, 2013, in Dhaka, Bangladesh.

IntroductionWorldFish has distributed planting vines of Orange Fleshed Sweet Potato (OFSP) as apart of the CSISA and IFAD Project.Some OFSP are high in vitamin A , introduced as a new vegetable in homesteadgardens for improving nutrition of women and young children.Vitamin A deficiency is a nutritional problem in Bangladesh. Vitamin A can be stored inthe body and therefore seasonal consumption is not a problem.Both roots and leaves are being promoted for consumption.Sweet potato (SP) is not a staple food in the Bangladeshi diet. Requires minimalmanagement; can grow on marginal soils and is saline-tolerant. SP is an important cropfor disaster relief.OFSP integrates well in aquatic agricultural systems, cultivated on dykes of ghers andponds.The introduction of OFSP, in particular combined with other foods such as nutrient-richsmall indigenous fish, holds great potential for improving nutrition and generate incomeamong rural households.
ObjectivesIntroduction of OFSP as a vitamin A-rich vegetablein the homestead garden and dykes of ghers andponds to improve nutrition and generate incomes.
UNDERTAKEN ACTIVITIESValue Chain Activities • Training on OFSP cultivation andProduction propagation • Acceptability studies of consumption roots and leavesConsumption • Analysis of nutrient composition • Small market of OFSP Leaves and rootsMarketing • Big market of vines
Undertaken Activities PRODUCTION• Training on cultivation of OFSP (80% households did not know)• Planted October- November 2011. Harvest: leaves January- April, roots - April.
Undertaken Activities Production Participants • CSISA: 568 households (predominantly smallholder marginal and women farmers involved in small scale aquaculture. • IFAD funded Fish and Nutrition Project (Rangpur, Dinajpur): 64 Households • Helen Keller International (HKI) (Khagrachari): 21 Households
Undertaken Activities Production OFSP Varieties• Three varieties of OFSP were planted. Total vines 63,500• SP4 (medium vitamin A and low dry matter) SP7 (low vitamin A and high dry matter) and SP8 (low vitamin A and high dry matter). BARI SP4 BARI SP7 BARI SP8 (orange flesh (cream flesh and (pale orange flesh and skin) yellow skin) and red skin)
Undertaken Activities CONSUMPTION Cooking Demonstrations • The OFSP leaves and roots were prepared using local methods and ingredients.
Undertaken Activities Consumption Acceptability study • The tasting evaluation of the OFSP leaves and roots by women and young children.
Undertaken Activities Production Acceptability• OFSP requires minimal labor, fertilizer and pesticide; saline-tolerant and grow on marginal soils.• Problems: Weevils. Late planting. Vines theft (leaves).
Nutritional Analysis• Preliminary results Total carotenoid in the OFSP leaves samples :
Undertaken Activities MARKETING• HH generated incomes by selling: Product Unit Price (BDT)Leaves Kg 10-15Roots Kg 15-22Vines vine 0.5
Carrying out of Activities • Increase number of hh with OFSP. Last year 653 hh, this year 2580 • 49% coming from Households production, 51% BRAC Projects Total Vines Total # beneficiaries CSISA 138500 1385 FtF Aqua 39000 390 IFAD 40500 405 HKI 40000 400 Total 258000 2580
Carrying out of Activities• M&E - Data collection for economic analysis of OFSP performance: production, costs and incomes.• Nutritional value of sweet potato leaves and roots, raw and cooked samples.• Propagation of sweet potato vines from the households that planted OFSP to continue planted for the next season.• Get more get Nutrient rich varieties of OFSP in collaboration with CIP.
Conclusions• The positive acceptance of women in growing OFSP for consumption and market gives a good potential for inclusion in aquatic agricultural systems.• Growing OFSP is beneficial, it requires minimal labor and inputs (fertilizer and pesticide). It can be planted on little land like homestead garden, dykes of ponds, and integrate well in aquaculture agricultural systems.• OFSP is a dual purpose crop as both leaves and roots can be eaten, and can be included in the daily meal of the families to improve their nutrition.• The marketing of roots, leaves and vines is great potential for generation incomes.• Working with partners to select suitable OFSP varieties with high vitamin A content in both leaves and roots, which can be recommended as nutrient – rich foods to complement local meals of hh.
