India is among top few countries for Vitamin A deficiency as 60,000 children go blind annually. Other than blindness, a number of eye diseases like night blindness, bitot spot, xerothalmia and others are caused by vitamin A deficiency. More than 6% children in Uttar Pradesh suffer from clinical vitamin A deficiency. Vitamin A deficiency among poor children in Gorakhpur average to 42% (as high as 65% in 3 year age group). Government of India, supported by CIDA, Helen Keller International, Micro-nutrient Initiative, UNICEF, USAID and the World Bank distributed free vitamin A capsule. Results were positive and dramatic but met failure due costs involved, problem in distribution, and corruption. Sustainable solution with no costs to government is popularization of Orange Fleshed Sweet Potato (OFSP) varieties, which have yellow or orange flesh due to very high level of â-carotene (precursor of Vitamin A). OFSP also supply required quantity of Potassium, dietary fibre, and energy. OFSP produces more edible energy per unit and people can grow, store and consume throughout the year. Supported by Tata Trusts since last 3 years, PRDF tested more than 50 OFSP varieties and identified ST-14, CIP-440127 and VA-43 adapted to the region now popularizing its growing and consumption enjoining hundreds of farmers and thousands of school children. A cycle of multiplying healthy vines has been perfected and being practiced. A number of products of leaf and tuber like Pakora, chips, juice etc have been developed. More needs to be done on research and awareness fronts.

Orange Fleshed Sweet Potato

Purpose: Vitamin A deficiency is among major health problems worldwide that leads to blindness, retarded growth and death, particularly in developing countries. In these countries, vitamin A deficiency largely affects pre-school children, pregnant and lactating mothers, and the rural poor. For instance, the predicted prevalence of vitamin A deficiency for 36 sub-Saharan African countries is 19.1 %. Methods: Different strategies, including vitamin A supplementation, food fortification and dietary diversification, have been used to combat this problem. However, these strategies are not sustainable due to their high costs. Results: Orange-fleshed sweet potato (Ipomoea batatas L. Lam) is a low priced crop, which is part of staple foods in most of sub-Saharan Africa that can be a year-round source of vitamin A. Most of the orange-fleshed sweet potato varieties contain 3000 - 16000 μg 100 g-1 of β-carotene and this contributes to 250 to 1300 μg 100 g-1 Retinol Activity Equivalents (RAE). Therefore, by using orange-fleshed sweet potato, it is possible to improve vitamin A status, increase the bio-availability of different micro-nutrients such as Fe, Zn, Ca and Mg, reduce vitamin A deficiency and hence reduce child mortality rates by 23 to 30 %. Conclusion: The article highlights the significance of vitamin A for human nutrition, the effect of vitamin A deficiency, the different prevention methods and the potential of orange- fleshed sweet potato as a food crop to prevent vitamin A deficiency.

Roots of orange-fleshed sweet potato varieties currently available in Nigeria contain high quantities of β-carotene or pro-vitamin A but have high moisture content. These varieties have been found to be a cheap and crucially important remedy for vitamin A deficiency. The cream or white-fleshed varieties, on the other hand, have a sweet taste with high dry matter content, giving a dry texture, a quality trait preferred in Nigeria. Development of sweet potato genotypes that can combine these two important quality traits is the objective of this breeding work. A diallel experiment using six parental sweet potato genotypes crossed in all possible combinations were carried out and thirty progenies were evaluated for beta carotene (β-carotene) and dry matter content in Landmark University, Omu Aran, Kwara State, Nigeria. The 30 F1 progenies along with their parental lines were planted in the same field trial. The trial was laid out in 6 x 6 triple lattice in two replications. Highly significant (P≤ 0.01) differences were observed among the genotypes for the traits. The average β-carotene content among the progenies was 2.86 (mg/100g.f.w) while the dry matter cttgontent had a mean value of 31.89%. The cross progenies 199024.2 x Excel had the highest beta carotene (14.37mg/100g.f.w) content with the highest dry matter content (40.10%) and are therefore recommended for further evaluation.

Orange Fleshed Sweet Potato

Vitamin A deficiency (VAD) and under nutrition are major public health concerns in developing countries. Diets with high vitamin A and animal protein can help reduce the problem of VAD and under nutrition respectively. In this study, composite flours were developed from orange fleshed sweet potato (OFSP), amaranth leaves and skimmed milk powders; 78:2:20, 72.5:2.5:25, 65:5:30 and 55:10:35. The physico-chemical characteristics of the composite flours were determined using standard methods while sensory acceptability of porridges was rated on a nine-point hedonic scale using a trained panel. Results indicated a significant (p < 0.05) increase in protein (12.1 to 19.9%), iron (4.8 to 97.4 mg/100 g) and calcium (45.5 to 670.2 mg/100 g) contents of the OFSP-based composite flours. The vitamin A content of composite flours contributed from 32% to 442% of the recommended dietary allowance of children aged 6–59 months. The composite flours showed a significant (p < 0.05) decrease in solubility, swelling power and scores of porridge attributes with increase in substitution levels of skimmed milk and amaranth leaf powder. The study findings indicate that the OFSP-based composite flours have the potential to make a significant contribution to the improvement in the nutrition status of children aged 6–59 months in developing countries.

Significant Difference

A Field experiment was conducted during the 2018 cropping season, at the Teaching and Research Farm of the Department of Agriculture Federal College of Education, (FCE) Yola. Yola is located in Northern Guinea Savanna Zone at latitude 9o­14’ North and longitude 12o38’ East and altitude of 158m above sea level. The treatments for experiment consist of two potato cultivars (White and Red) which vines were obtained from the open market in Yola and slips prepared from previous year’s tubers. Complete Randomized Block Design (CRBD) was used and the treatments were replicated three (3) times. Both sweet and white potatoes provide similar amounts of key nutrients including protein (2g and 3g respectively), potassium and vitamin B6, all of which contribute to a well-balanced, nutrient-dense diet. It has 20.1g CHO, Starch 20.1g, Sugars 4.2g, Dietary fiber 3g, Protein 1.6g and fat 0.1g. Soups, leaves and shoots are edible, Tubers roasted in many African Countries such as Kenya, South Sudan, Liberia, Guinea and Nigeria.their increased cultivation is being encouraged in Africa where vitamin A deficiency is a serious health problem. he highest yield of 8 tones/ha-1 was recorded on the red cut vines, followed by 6 tones/ha-1 on the white cut vines. There were no significant difference on the spread/uncut vines which gave yields of 3.6 tones/ha-1 and 4.8 tones/ha-1 while significant difference were observed on the cut vines with a mean weight tuber of 6.5 and 8.1 respectively. Results in sweet potato showed that, it has a good potential to the farmers in terms of yield and income. Their increased cultivation is being encouraged in Africa where vitamin A deficiency is a serious health problem. Their differences in terms of yield between the white and the red cultivars might be due to the methods adopted for planting the vines. It is therefore recommended to cut the vines when planting in order to obtain higher yield since yield is an important factor to be considered for sweet potato production.
