Orange-Flesh Sweet Potato Farming in India 2026
Grow beta-carotene rich orange sweet potato for health-conscious and nutrition markets.
Overview
Orange-flesh sweet potato, or OFSP, is a high-value upgrade over ordinary white sweet potato because its deep orange colour comes from beta-carotene, a source of vitamin A that nutrition programmes and health-conscious buyers actively seek. ICAR-CTCRI has released varieties like Bhu Sona with very high beta-carotene of around 12 to 14 mg per 100 grams, far above ordinary types. The commercial angle is branding the crop as a nutritious superfood for urban retail, processing into flour, chips and puree, and supplying nutrition and mid-day-meal programmes. It grows fast, in 90 to 120 days, on marginal land with low inputs, making it attractive for diversification. This page focuses on the high-value nutritional and market positioning of OFSP rather than basic sweet potato growing, so you can capture the premium that colour and nutrition command.
Climate
Sweet potato is a warm-season crop preferring 21 to 27 degrees Celsius with adequate sunshine and 75 to 150 cm of well-distributed rainfall. It is fairly drought tolerant once established and does not suit frost. It is grown in kharif and rabi in different regions and can fit into rice fallows and rainfed areas, which adds to its appeal as a low-risk crop.
Soil
Well-drained sandy loam or loam with good organic matter and a permeable subsoil gives the best tuberous roots, with pH 5.5 to 6.8. Loose friable soil lets roots expand. Heavy clay and waterlogging cause small, cracked or rotting roots. Ridges or raised beds improve root shape, drainage and ease of harvest.
Planting & Spacing
Plant 20 to 30 cm vine cuttings with three or four nodes on ridges at about 60 by 20 cm spacing. Plant in the main season from June to August in rainfed areas or with irrigation in other windows. Use healthy, disease-free vine material from a reliable nursery and plant cuttings slanting so several nodes are buried for good rooting.
Varieties
Bhu Sona from ICAR-CTCRI has the highest beta-carotene at around 12 to 14 mg per 100 grams and is the flagship OFSP variety. Other orange-fleshed types include Bhu Kanti, Sree Kanaka, Gouri and Kamala Sundari. For early harvest, Sree Arun and Sree Varun mature in 90 to 100 days. Choose a high beta-carotene variety to justify the nutritional premium.
Care & Management
Apply moderate FYM and balanced NPK, taking care not to over-apply nitrogen which gives leafy vines and small roots. One or two weedings and vine lifting to prevent rooting at every node keep root size high. Irrigate during dry spells in the early growth and root bulking stage, then reduce water before harvest to improve quality.
Pests & Diseases
The sweet potato weevil is the most serious pest, boring into roots and making them bitter and unsaleable, worsened by exposed roots and dry cracked soil. Manage with clean vine material, crop rotation, earthing up to cover roots, pheromone traps and timely harvest. Avoid replanting on weevil-infested land. Leaf-feeding caterpillars are minor by comparison.
Yield & Harvest
Harvest at 90 to 120 days when leaves start yellowing and roots reach size; early varieties finish in 90 to 100 days. Dig carefully to avoid cuts that invite rot, then cure in warm shade for a few days to heal skins and improve storage and sweetness. Cured orange roots store and transport better and command better retail prices.
Cost & Profit
Sweet potato is a low-input crop, so costs are modest compared with many tubers. Orange-flesh yields are often reported around 20 to 28 tonnes per hectare for good varieties. Plain sweet potato sells cheaply, but branded high beta-carotene OFSP for health-conscious retail, processing and nutrition programmes can fetch a premium. All yield and price figures are indicative ranges that depend on variety, market and season, so verify locally before scaling up.

Market & Demand
Sell OFSP into urban health-food retail, online grocery, and processors making flour, chips, puree and baby food, as well as nutrition and supplementary feeding programmes that want vitamin A rich foods. Branding it as a beta-carotene superfood and supplying clean, cured, graded roots earns more than dumping at a vegetable mandi. FPOs and tie-ups with processors help build steady demand.
Subsidy & Support
Sweet potato is covered under MIDH as a tuber crop with support for planting material and area expansion, the Government of India funding 60 percent in most states and 90 percent in Northeast and Himalayan states. ICAR-CTCRI and state agriculture departments promote OFSP for nutrition, and biofortification and nutrition missions sometimes support vitamin A rich crops.
