Potato Farming

  1. Grown Areas:

  • Sweet potato is good for heart and helps in controlling blood sugar due low glycemic index.
  • In India cultivate in Uttar Pradesh, Bihar, West Bengal, Madhya Pradesh, Assam, Telengana, Maharashtra, Orissa, Andhra Pradesh, Tamil Nadu.
  1. Nutritive and Medical Value:

  • It also prevents essential pigments from being produced.
  • Correcting vitamin A deficiencies with foods high in beta-carotene can restore vision.
  • Also of note, the antioxidant vitamins C and E in sweet potatoes have been shown to support eye health and prevent degenerative damage.
  1. How Can Grow…?

  • Sweet potato mature in 90 to 170 days and are extremely frost sensitive.
  • Plant in full sun 3 to 4 weeks after the last frost when the soil has warmed.
  • Make holes 6 inches deep and 12 inches apart. Bury slips up to the top leaves, press the soil down gently but firmly, and water well.
  1. Varieties of Potato Cultivated in India:

  • Generally, sweet potato cultivars/varieties differ in size, shape, colour of leaves, tubers & nature of tuber flesh.
  • Varsha, Sree Nandini, Sree Vardhini, Sree ratna, Cross-4, Kalmegh, Rajendra Shakarkand-5.
  1. Growing Requirement:

  • Sweet Potatoes are grown in warm tropicland subtropical frost free regions with ideal temperature of 21 c to 26 c.
  • It requires well and evenly distributed rainfall of 75 to 150 cm for optimum production.
  • Heavy rainfall will damage the crop and does not allow proper growth as aids in excessive vegetative tuber growth.
  • This crop requires plenty of sunshine at least 5 months. It can tolerate drought conditions but not the water stagnation.
  • Low temperatures below 10 c and frost conditions will check the growth of the tubers. This crop can be grown areas up to 2200meters above the mean sea level (m.s.l).

  1. Suitable soil/Land Preparation:

  • Sweet Potatoes cultivation requires a well-drained sandy loam soil rich in humus with clay(losse) sub soil for best tuber production.
  • If the soil ph is less than 5.3, liming the soil is required. In case of heavy soils, tuber size will be less.
  • The ideal ph range of soil should be 5.7 to 6.7 for best yield of the tubers.
  1. Best Planting season:

  • Unlike regular potatoes, which grow best the soil is cool, sweet potatoes like it hot. They tropical plants that are very sensitive to cold wether.
  • In warm climates, many gardeners plant sweet potatoes about a month after the last spring frost, when both the air and soil are dependably warm.
  • Sweet potato vine cuttings should be planted during june to july for rainfed conditions.
  • Under irrigate conditions, planting should be done during Oct to Nov in uplands & should be done during Jan to feb in low lands for summer crop cultivation.
  1. Spacing Between Plants:

  • Make the ridges of 25 to 30 cm height at 60 cm apart after giving couple of ploughings in the main field.
  • Vine cuttings with the length of 20 to 30 cm should be  horizontally with 2 to 3 nodes below the soil by leaving the remaining portion of the cutting above the soil.
  1. Fertilizers and Nutrition requirements:

  • As part of the land preparation, supplement the well rotten farm yard manure of 25 tones in the soil.
  • In organic fertilizers of N: p: k should be apply in ratio of 60:60:120 kg/ha. Full doses ‘p’, ‘k’ and ½ dose of ‘n’ should be apply at the time of planting.
  • Apply remaining ½ dose of ‘n’ after 1 month of the planting sweet potatoes.
  • Avoid excessive irrigation as it checks the yield by allowing more vegetative growth.
  • In kharif season, sweet potato crop requires less irrigation.
  • During rabi and hot dry seasons, 10-12 irrigations are require at an interval of 8 to 10 days for high production.
  • However, make sure to have sufficient moisture in the soil after 40 to45 days of planting.
  • Frequency of irrigations depends on the soil moisture holding capacity and climatic conditions of the area.

  1. Water supply/Irrigation:

  • Keep your potato vines well water throughout the summer, especially during the period when the plants are flowering and immediately following the flowering stage.
  • During this flowering period the plants are creating their tubers and a steady water supply is crucial to good crop outcome.
  • Potatoes need consistent moisture, so water regularly when tubers start to from potatoes do well with 1-2 inches of water or rain per week.
  • When the foliage turns yellow and begins to die back, discontinue watering.
  • This will help start curing the potatoes for harvest time. Drip irrigation helps Indian farmers increase potato yield.
  1. Disease:

  • Stem rot
  • Flea Beetles
  • Fungal leaf rot
  • Sweet potato scurf
  • White blister

  1. Inter-cropping:

  • Potato may be different types of cropping systems, ego as okra. No inter-cropping in potatoes farming.
  1. Storage/Harvest:

  • You can start digging up the potatoes as soon as they are big enough for a meal. Often, this is 3-4 months from when you plant the slips.
  • Usually, sweet potatoes are ready to harvest when the leaves and ends of the vines have start turning to yellow, but you can leave them in the ground up until the fall frost.
  • Since the roots spread 4 to 6 inches deep in the soil, a spade fork is useful when digging up the potatoes. Loosen the soil around the plant so you do not injure the tubers. It’s fine to cut some of the vines away.
  • Pull up the primary crown of the plant and use your hands to dig up the potatoes. Handle the potatoes carefully because they bruise easily.
  • After digging up the potatoes, shake off any excess dirt but do not wash the roots.
  • Store the sweet potatoes in a root cellar, basement or other place with a temperature of at least 55F.
  • If store at a temperature range of 55 to 60F with high humidity, the tubers should last for about 6 months. When removing the potatoes from storage, remember to be gentle; do not dig around or else you will bruise the potatoes.
