ICAR-CTCRI Develops Orange-Fleshed Sweet Potato

April 1, 2025

The ICAR-Central Tuber Crops Research Institute (ICAR-CTCRI) developed an orange-fleshed sweet potato (SP-95/4) to improve tribal food security in Kerala and other states. It has successfully passed final trials in Odisha, West Bengal, Karnataka, and Kerala.

Nutritional Benefits

Contains 8 mg/100g of Beta-carotene, which helps combat Vitamin A deficiency, a common issue in tribal areas.
The average tuber weighs 300 grams and has a fusiform shape, making it ideal for processing.

Future Expansion Plans

The project currently operates on 10-15 acres but aims to expand to 100 acres by the end of 2025. Plans include establishing a processing unit funded by Corporate Social Responsibility (CSR) initiatives. This expansion will further enhance food security and economic opportunities for local farmers.

Research and Development

The SP-95/4 variety has undergone extensive trials across multiple states, including Odisha, West Bengal, and Karnataka. The trials confirmed its suitability for various climatic conditions and its potential for high yields. The final set of trials in Attappadi showed promise for the variety.

Broad Initiatives

The cultivation was part of two initiatives:
- Rainbow Diet Programme (by CTCRI, started in 2023).
- Punarjeevanam (a joint effort of Kudumbashree & CTCRI, expanded in 2024).
Goal: Expand sweet potato farming in Attappady to 100 acres by 2025.

Rainbow Diet Programme

The Rainbow Diet Programme, launched by CTCRI, aimed at promoting biofortified tubers among tribal communities. It focuses on improving dietary diversity and nutritional intake. The programme was scaled up under the Punarjeevanam initiative, reinforcing its objectives.

Public Health Implications

Integrating sweet potatoes into local diets addresses nutritional insecurity. The project aligns with public health strategies to combat malnutrition and improve overall health among tribal populations. Sweet potatoes can play a vital role in health-focused dietary support.
