Soils for potato should be friable, well aerated, fairly deep and well supplied with organic matter. Well drained sandy loam and medium loam sols, rich in humus are most suitable for potato. Light soils are preferred because they tend to promote more uniform soil temperatures and make harvesting of the crop easier. Alkaline or saline soils are not suitable for potato cultivation. They are well suited to acidic soils (pH 5.0 to 6.5) as acidic conditions tend to limit scab disease.

20°C to 30°C

Tuber purpose: Kufri Jyoti, Kufri Megha, Kufri Giriraj, Kufri Kanchan (red tuber), Kufri Himalini, Kufri Girdhari
Chips purpose : Kufri chipsona -1, Kufri chipsona -2 and Kufri chipsona -3

Soil should be prepared by 2-3 deep ploughing with plough or spade followed by harrowing. If necessary, planking may also be done to make the soil cloudless. Enough moisture is essential at the time of sowing.

A row to row distance of 45 to 60 cm and plant to plant 15 to 20 cm should be maintained in the main crop.

a) Plains- 10th October to 25th October
b) Hills- February for Valleys and March-April at higher altitudes.

About 20-25 quintals is sufficient for planting one hectare area.

Potato requires high manuring and special care should be taken for supplying potassium in adequate quantity. Application of FYM @ 10 t /ha along with vermicompost 5 t, neem cake 150 kg and rock phosphate and 150 kg/ha is recommended for good yield of potato. Liming @ 500 kg/ha in furrow reduces the problem of diseases in potato under acid soil of north east India

Potato crop is very much responsive to good water management. Drainage of excess water is essential. In no case water should reach more than two-thirds height of the ridges. Soil must be kept always moist but hardening or too wet conditions of soil should not be allowed. Irrigation may be moderate to heavy but over-flooding of water on ridges should be avoided. Medium to heavy soils: 3 to 4 irrigations Sandy soil-12 irrigations.

Weeding should be done as soon as the weeds appears. The final earthing up should be done when the plants are 10-15 cm height (30-35 DAP)

Harvesting should be done on bright sunny days. Heap the produce in shade for curing of skin and the heap left undisturbed for 15- 20 days.

Under rainfed condition the average yield of 20 – 25 t/ha potato tubers can be obtained
