Potato (Solanum tuberosum) is a staple food in many European countries and has been proven to be valuable in providing food during emergencies. It is an important source of starch. It could be a wealthy source of body-building substances such as carbohydrates, vitamins (B1, B2, B6, and C), minerals (Ca, P, and Fe), and protein.

• Ideal conditions for better growing potatoes :

Soil: 

Almost all types of soil are are reasonable for the development of potato. The well drained clay loam soil with pH between 5.0 and 7.5 is considered as ideal for its cultivation. On sandy loam soil, crop can be effectively developed given manuring is done intensely and the crop is irrigated properly and timely.

Climate :

It could be a cool season crop and can endure moderate frost. It requires a soil temperature of 20°C for better germination. Young plant growth is good at 24°C but later growth is favoured by a temperature of 18°C. No tuberization takes place when the night temperature exceeds 23°C. Maximum tuberization occurs at 20°C. Tuber formation stops completely at about 29°-30°C.

Planting Season :

Planting time varies by region. In northern India, it’s from October to November, while in southern India, it’s from June to July.

Soil Preparation :

Deep ploughing helps in breaking hardpans and enhancing soil aeration. The fields are ploughed to a depth of 20-35 cm first with soil turning plough and afterwards by 4 to 5 ploughing with country plough/disc harrow.

Seed Selection, Varieties & Seed Rate :

1. Seed Selection: Use certified, disease-free seeds from reliable sources.
2. Varieties: Choose varieties suitable for the region and resistant to local pests and diseases.
3. Seed Rate: 25-35 q/ha.

Seed Treatment :

1. Fungicide Treatment: Treat seeds with fungicides to prevent fungal diseases.
2. Sprouting: Pre-sprout seeds by exposing them to light for 10-14 days.

Planting Season :

Planting time varies by region. In northern India, it’s from October to November, while in southern India, it’s from June to July.

Spacing :

Maintain a spacing of 45-60 cm between rows and 20-25 cm between the tubers within the rows to ensure adequate growth.

Breaking of Dormancy:

Hill tubers can not be used for autumn crop immediately because of dormancy period of 2-3 months in tubers. This dormancy can be broken by utilizing a few chemicals –

1. Thiourea (Sodium Potassium thiocynate) @ 1-2% solution which is used as a treatment to cut tubers for 1-1.5 hours and about 1 kg of thiourea is sufficient for 10 quintals of seed tuber. (Or)
2. Tubers are kept in 5 ppm solution of GA3 for 10 seconds.

Manures and fertilizers :

Apply FYM (farmyard manure) @100q/ha at the time of field preparation. Fertilizer dose varies depending upon the fertility of the soil. However, fertilizers are applied @ 120:80:60 kg N: P2O5: K2O /ha, respectively. Full dose of farmyard manure, phosphorus and potassium and half of N should be applied at the time of planting.
