Potato Cultivation in India: Importance, Scope, Challenges and the Future of Potato Research

Few crops travel as well as the potato. Domesticated in the Andes of South America thousands of years ago, it reached Europe in the sixteenth century and India by the seventeenth. Today it is grown from the plains of Uttar Pradesh to the hills of Meghalaya, and it appears in almost every Indian kitchen, from aloo pitika in Assam to aloo paratha in Punjab.

In much of Europe and the Americas, potato is a staple food eaten in place of bread or rice. In India it is mostly eaten as a vegetable, but its importance goes far beyond the plate. It is one of the country’s most productive crops, a key part of rabi cropping systems, and the raw material for a fast-growing processing industry.

This article explains why potato matters, its scope in India and Assam, the problems farmers face, and the directions research is taking.

Why potato matters

A highly productive crop

Potato produces a large amount of food from a small area in a short time. Most varieties are ready in 70 to 120 days, and good crops yield 25 to 30 tonnes or more per hectare. Because the tuber is the edible part, a high share of the plant’s dry matter ends up as food. For a country with small farms and a growing population, this efficiency is valuable.

India’s place in world potato production

India is the world’s second-largest potato producer after China. According to the Ministry of Agriculture’s estimates, India produced about 602 lakh tonnes (60.2 million tonnes) of potatoes in 2024–25, up from about 571 lakh tonnes the year before. Potato is the most important vegetable crop in the country by production.

The main producing states are Uttar Pradesh, West Bengal, Bihar, Gujarat, Madhya Pradesh and Punjab. Assam is also among the top ten producing states, though its yields are much lower than the national average.

Nutritional value

Potatoes are often thought of as “just starch”, but they offer more than that. According to the US Department of Agriculture’s FoodData Central, 100 g of raw potato (flesh and skin) provides approximately:

Nutrient	Approximate amount per 100 g
Energy	77 kcal
Carbohydrate	17 g
Protein	2 g
Fat	0.1 g
Dietary fibre	2 g
Vitamin C	20 mg
Potassium	425 mg

So potatoes are low in fat and a good source of energy, vitamin C and potassium. How they are cooked matters: boiled or baked potatoes, eaten with the skin, are a healthy food, while deep-fried chips and fries add a lot of fat and salt.

Economic importance

Potato supports millions of livelihoods across the value chain: farmers, seed producers, labourers, cold-storage operators, traders, transporters, processors and retailers. Because it is a short-duration crop, it fits between other crops in the year, allowing farmers to grow two or three crops on the same land and earn more from it.

Scope of potato cultivation

Fitting into cropping systems

In the plains of India, potato is a rabi (winter) crop, usually planted in October or November and harvested in January to March. In the hills, it is grown in summer. Its short duration makes it a good fit in many cropping systems. Common potato-based systems include:

Cropping system	Where it is common	Why it works
Rice–potato	Assam, West Bengal, Bihar, eastern UP	Potato uses residual moisture and fertility after kharif rice
Rice–potato–wheat (late-sown)	Indo-Gangetic plains	Early potato varieties allow late-sown wheat to follow
Maize–potato–wheat	Punjab, Haryana, western UP	Three crops a year on irrigated land
Rice–potato–mungbean or sesame	Eastern India	A short summer pulse or oilseed adds income and improves soil
Rice–potato–onion	West Bengal, Bihar	Onion follows potato as a high-value summer crop
Potato intercropping (with mustard, maize or sugarcane)	Various regions	Better use of land and spreading of risk

The right system depends on the local climate, irrigation, soil and market. Farmers should follow their state agricultural university’s or KVK’s recommendations.

Scope in Assam

Assam has large areas of land left fallow after the Sali rice harvest, and much of this could grow potato. One approach that has been tested in the state is zero-tillage potato, in which seed tubers are placed directly in the rice field after harvest and covered with rice straw, using the moisture left in the soil. This saves the cost of ploughing and makes use of land that would otherwise lie idle.

The potential for higher yields is also clear. In an on-farm trial reported in Indian Horticulture, improved varieties (Kufri Pukhraj and Kufri Jyoti) grown with quality seed and improved practices in Assam averaged about 28.7 t/ha, compared with about 9.4 t/ha from the farmer’s local variety grown in the traditional way. Results from a single trial can’t be generalised, but they show how much better seed and practices can help.

Scope in processing

Demand for processed potato products is growing quickly in India, driven by urbanisation, the fast-food sector and changing diets. The main processed products are:

• Chips and snacks, the largest use of processed potatoes in India.
• French fries, increasingly supplied as frozen, ready-to-cook products.
• Flakes, granules and flour, used in ready-to-eat foods and as thickeners.
• Starch, used in food, textile, paper and pharmaceutical industries.

Processing needs special varieties with high dry matter and low sugar content. ICAR-Central Potato Research Institute (CPRI) has developed processing varieties such as the Kufri Chipsona series for chips and Kufri FryoM for French fries. Contract farming for processing companies is giving some farmers assured markets.

Challenges in potato cultivation

Diseases and pests

Late blight, caused by Phytophthora infestans, is the most serious potato disease worldwide. It was behind the Irish potato famine of the 1840s, and it still causes heavy losses in cool, humid weather, conditions common in Assam and the North-East during the winter season. Other important problems include early blight, bacterial wilt, black scurf, viral diseases spread by aphids, and pests such as cutworms and potato tuber moth.

Shortage of quality seed

Seed tubers are bulky and expensive, often making up a large share of the cost of cultivation. Many small and marginal farmers reuse their own seed for several seasons. Over time, this seed picks up viruses and other diseases, and yields fall. In Assam and the North-East, where seed often has to come from distant regions, access to good-quality seed is a particular challenge.

Storage and marketing

Potato is harvested in a short period, so prices often fall sharply at harvest time. Without enough cold storage nearby, farmers are forced to sell at low prices or risk losses from rotting, sprouting and weight loss. Poor roads, transport and market information add to the problem.

Climate change

Potato grows best in cool weather. Rising temperatures, especially warmer winter nights, can reduce tuber formation and yield. Changing rainfall and humidity patterns can also increase the risk of late blight.

The future of potato research

Researchers in India and around the world are working on several fronts.

Breeding better varieties

Breeding programmes aim for varieties that combine high yield with:

• resistance to late blight and viruses;
• tolerance to heat, so potato can be grown in warmer areas and seasons (for example, Kufri Surya);
• suitability for processing;
• better nutrition, such as higher levels of antioxidants in coloured potatoes like Kufri Neelkanth.

A newer area of research is hybrid potato breeding, which aims to develop varieties that can be grown from true seed rather than tubers. If successful, this could make planting material cheaper and easier to transport.

Better seed systems

Modern techniques such as tissue culture, aeroponics (growing minitubers in the air with nutrient mist) and apical rooted cuttings can produce large quantities of disease-free planting material quickly. Scaling these up, along with decentralised seed production by farmers’ groups, could help solve the seed problem in regions like the North-East.

Precision agronomy

Research is refining area-specific packages of practice, with better management of nutrients, water and mulching. In Assam, studies on phosphorus nutrition, fertiliser levels and mulching (for example, by Borah, Sharma and Saikia) have contributed to local recommendations. Drip irrigation, soil testing and sensor-based monitoring are being tested for higher efficiency.

Disease forecasting and management

Weather-based forecasting systems that warn farmers when conditions favour late blight allow fungicides to be applied only when needed, saving money and reducing chemical use. Research also continues on resistant varieties, biological control and integrated disease management.

Post-harvest technology

Researchers are working on better storage methods, low-cost storage structures for areas without cold storage, and safer sprout control, so that farmers can store potatoes longer and sell when prices are better.

International collaboration

In June 2025, the Union Cabinet approved the establishment of the International Potato Center’s (CIP) South Asia Regional Centre at Singna, Agra, in Uttar Pradesh. The centre will work on high-yielding, nutritious and climate-resilient potato and sweet potato varieties and value chains, which could benefit farmers across South Asia, including the North-East.

Conclusion

The potato is far more than a humble vegetable. It is one of India’s most productive crops, a flexible partner in rice- and maize-based cropping systems, a source of affordable nutrition, and the foundation of a growing processing industry.

At the same time, farmers face real challenges: late blight, poor-quality seed, price crashes at harvest and a warming climate. In Assam especially, low yields show both the problem and the opportunity. With better varieties, healthier seed, improved practices such as zero-tillage potato in rice fallows, and stronger storage and marketing, potato can do much more for farmers’ incomes and the country’s food security.
