Bhubaneswar, May 14: The ICAR-Central Tuber Crops Research Institute (ICAR-CTCRI) has developed the biofortified orange-fleshed sweet potato varietySP-95/4, featuring pink skin and vibrant orange flesh. Specifically designed to combat Vitamin A deficiency (VAD) and enhance food security, this variety represents a significant advancement in nutritional crops.
Combating Malnutrition with Orange-Fleshed Sweet Potato (OFSP)Orange-fleshed sweet potato (OFSP) is recognized globally as a highly effective crop in the fight against VAD and malnutrition, particularly in sub-Saharan Africa and Asia. A daily intake of approximately 125 grams of OFSP can meet a child’s recommended vitamin A requirement, supporting immunity and preventing blindness.
Key Nutritional and Agricultural Benefits
- High β-carotene Content: OFSP is rich in β-carotene, a vitamin A precursor, helping reduce deficiencies in rural and vulnerable populations.
- High Yields and Early Maturity: These varieties are drought-tolerant, early-maturing, and suitable for multiple harvests annually.
- Versatility: Beyond the roots, the plant’s leaves and vines are edible. OFSP can also be processed into puree for bakery and other value-added products.
- Health Benefits: Provides essential nutrients and energy, contributing to reduced duration of childhood diarrheal illnesses.
Impact on Malnutrition Eradication
- Wide Adoption: Over 6.8 million households in Africa and South Asia cultivate and consume OFSP.
- Nutritional Intervention: Studies show significant improvement in vitamin A status among children, lowering malnutrition-related illnesses.
- Economic Empowerment: OFSP cultivation offers income opportunities, particularly for women, promoting agricultural development.
- Specialized Varieties: More than 100 OFSP varieties have been developed to enhance dry matter content and overall nutritional quality.
