Elephant Foot Yam (Suran / Oal) Farming in India 2026
A high-yielding, low-risk tuber giving large corms and steady market demand.
Overview
Elephant foot yam, known as suran, oal or jimikand, is one of the most remunerative tuber crops because a single corm can weigh several kilograms and the crop has few pests, tolerates shade and gives steady prices. The high-value angle is choosing improved, low-acridity varieties like Gajendra and Sree Padma that are easy to cook and sell well, and using the crop in intercropping to boost income per acre. Demand is consistent in vegetable markets, for processing, and in religious and festival cooking across North and East India. Production potential is very high, often quoted at 50 to 80 tonnes per hectare. This page focuses on commercial cultivation and the variety and marketing choices that make suran profitable, rather than basic growing, so you can plan it as a serious cash crop.
Climate
Suran is a tropical crop needing warm humid weather of 25 to 35 degrees Celsius and 1000 to 1500 mm rainfall well spread over the season. It tolerates partial shade well, which makes it ideal under coconut, banana or orchards. It is grown across the plains of North, East and South India and does not suit frosty or very cold areas.
Soil
Deep, well-drained sandy loam or loam rich in organic matter gives the biggest corms, with pH 5.5 to 7.0. Heavy clay or waterlogged soils cause corm rot and deformed tubers. The soil should be loose so large corms can expand freely. Adding compost and ensuring drainage are the two most important soil steps.
Planting & Spacing
Plant corm pieces or whole small corms of 500 grams to 1 kg in February to May on pits or ridges at about 90 by 90 cm spacing, with seed rate often 8 to 12 quintals per hectare depending on piece size. Treat cut pieces with cow dung slurry and a biofungicide, dry them, then plant. Whole corms give a single large tuber while cut pieces are more economical on seed.
Varieties
Gajendra, a selection from Andhra Pradesh, is the most popular commercial variety with high yield of 50 to 80 tonnes per hectare and low acridity. Sree Padma, Sree Athira and the newer Swagata are improved low-acridity types that cook without throat irritation. Choose certified low-acridity varieties because high-oxalate local types irritate the throat and sell for less.
Care & Management
Apply generous FYM or compost with balanced NPK, since the crop is a heavy feeder building large corms. Two or three weedings, earthing up, and mulching conserve moisture. Irrigate in dry spells but never waterlog. Staking is not needed but support intercrops can share the land. Potassium is important for corm size and quality.
Pests & Diseases
Suran has relatively few pests, which is part of its appeal, but collar rot and corm rot occur in poorly drained soil, and mealybugs and Amorphophallus mosaic virus can affect it. Use healthy seed corms, drainage, crop rotation and biocontrols. Removing virus-infected plants and using clean planting material keep yields high.
Yield & Harvest
Harvest at 7 to 9 months when leaves yellow and the plant dries down. Dig carefully to avoid bruising the large corms, then cure in shade for a few days. Corms store well for one to two months in cool dry conditions, letting you sell when prices are favourable. A part of each corm can be kept as seed for next season.
Cost & Profit
Cost of cultivation is significant because of high seed corm cost, often reported between roughly 90,000 and 1.7 lakh rupees per hectare. Yields commonly run 30 to 50 tonnes per hectare and can reach 80 in ideal conditions. With steady demand, net returns of over 1 lakh rupees per hectare are frequently cited, and benefit-cost ratios around 1.3 to 1.5 are reported in studies. Treat these as indicative ranges and confirm seed cost and local prices before committing.
These are indicative ranges. Actual cost and income vary by region, market and management, so verify locally.
Market & Demand
Suran sells in vegetable mandis across North, East and South India, with strong demand during festivals like Diwali and in fasting and traditional cooking. There is also growing demand for processed products like chips and flour. Selling graded, clean, low-acridity corms and timing sales for festival peaks improves returns. FPOs and direct retail tie-ups help avoid distress sales.
Subsidy & Support
Elephant foot yam is covered under MIDH as a root and tuber crop, with assistance for area expansion and planting material, the Government of India funding 60 percent in most states and 90 percent in Northeast and Himalayan states. State horticulture missions and RKVY also support tuber crops and post-harvest infrastructure in many states.
