Favourable Climate

Climate
  • Potato is preferred in regions where temperature during growing season is cool
Temperature
  • The vegetative growth is best at 24 °C while tuber growth at 20 °C.
  • A temperature ranging from 20-25°C is ideal for growth.
Crop Water Requirements
  • Germination, underground stem formation and tuber development are the most critical stages when water must be available. 
  • Water requirement – Equivalent to 500-700 mm of rainfall

Favourable Soil

Type
  • The potato can be grown almost on any type of soil except saline and alkaline soils.
  •  Choose Sandy loam, Silt loam, Loam and Clay soil ( Soils should be loose).
pH
  • Required range- 5.0-6.5 (Slightly acidic Soil)
  • Strongly alkaline soils are not suitable for growing Potato.
  • If pH is <5.0 add Lime
  • If pH is >6.5 add Gypsum

Seed Treatment

Treat the tubers with- 

Mix Azotobacter – 4 kg in 200 lit of water in a drum for 800 kg seeds. 

Dip the seeds in a solution for 30 min & use for sowing.

Land Preparation

Land Preparation
  • Ploughing method – Plough the land 1 or 2 times based on soil type.
  • Mix the following in field, and keep it in open air for 10 days for proper decomposition – 
    1. FYM – 2 tons
    2. Composting Bacteria – 3kg
  • Spread the above mixture over soil and run rotavator to the entire field making the soil as a fine tilth
Bed Preparation
  • Bed preparation- Prepare ridges and furrows 60 cm apart with the help of tractor.

Sowing

  • The sprouted tubers should be planted in furrows 20 cm apart with sprouts facing upward.
  • Care should be taken to avoid sprout damage.

Nutrient Management

  • Total Nutrient Requirement: 40:55:40 N:P:K kg/acre. 
  • At sowing apply- Urea- 43 kg  , Single super phosphate- 338 kg, Muriate of potash- 67 kg , Magnesium Sulphate (MgSo4 )- 25 kg
  • 30 Days after sowing Urea- 22 kg 
  • 45 Days after sowing Urea- 22 kg 

Irrigation

  • Drip- Once in 3 days
  • Flood- First irrigation should be light and given 5-7 days after planting and subsequent irrigation are given at 7-15 days interval depending upon the climatic condition and soil type.

Intercultural Operations

Earthing Up: 2 times @ 30 days after sowing and 60 days after sowing (Convert ridges into furrows).

Growth Regulators

  • Foliar sprays with Ethephon at 100 gram or Gibberellic acid at 200 ml per acre in 200 lit water to increase tuber yield  at 30 and 70 days after sowing.
