The Ultimate Guide for Carrot farming (2018)

Carrot farming

Carrot is important root crops cultivated throughout the world for its fleshy edible roots. Carrot farming is done in the spring, summer, and autumn in temperate climate countries and during winter in tropical and subtropical regions.

Roots of carrot are used as a vegetable for soups & curries; graded roots are used as a salad, tender roots as pickles also Carrot halwa and jam are famous.

Carrot juice is a rich source of carotene and is sometimes used for colouring buffer and other food articles. Carrot tops are used for extraction of leaf protein, as fodder and also for the poultry feed.

Carrots possess many medicinal properties and are used in Ayurvedic medicine. Carrots are a rich source of b-carotene and contain appreciable amounts of thiamine and riboflavin.

The Carrot crop is the Second most popular vegetable in the world after potato. China ranks first in production followed by Russia.

The major carrot growing states in India are Karnataka, Punjab, Uttar Pradesh, Tamil Nadu, and Andhra Pradesh.

Soil requirement for Carrot farming

Carrots can be grown well in a wide variety of soils. However, the ideal soil for commercial carrot farming should be deep, loose, well drained, and rich in humus.

Loamy or sandy loam soils with sufficient quantities of humus are well suited to the cultivation of carrots.

The ideal pH range for obtaining good yield is 5.5-6.5. Soils with pH up to 7.0 can also be used, but too alkaline or acidic soils are unsuitable for this crop

Climate requirement for Carrot farming

Carrot is a cold weather crop, and it also does well in warm climates.

The optimum temperatures for getting excellent growth is between 16 to 20 °C, while temperatures above 28°C drastically reduce top growth.

Temperatures lower than 16°C affect the development of color and result in long slender roots, while higher temperatures produce shorter and thicker root.

The temperatures between 15 and 20°C result in attractive roots with excellent red color and quality.

Propagation

Carrot seed

Carrots are propagated using seeds.

The carrot seeds that are Sowing or broadcast in the field with a seed rate of 5 to 6 kg /ha or it can be up to 6 to 9 kg/ha this depends upon carrot variety.

The seeds are small approximately 800 per gram. They remain viable for nearly three years and up to 85% germination.

However, germination of some local varieties may be inadequate. Therefore, it is necessary to ascertain the germination percentage when calculating the seed requirement.

For best results, it is also necessary to procure clean, healthy, and viable seeds from reliable sources. The seeds take approximately 7-21 days for complete germination.

The best seed germination occurs at 20-30°C. The best time for Carrots cultivation in India is in September.

Planting of Carrot

Carrot-farming-fields

The soil for carrot cultivation should be properly prepared to get the desired yield. Therefore It is necessary that the field provides a loose, friable, deep, and well-drained for seeds to germinate. This can be achieved by repeated deep ploughing at least 20-30 cm deep followed by harrowing, leveling, and cleaning.

All old debris or remains of previous crops should be removed completely to obtain the desired seedbed condition. Since the seeds are very small and delicate, the seed bed should be very finely prepared. Beds of convenient size should be prepared before sowing.

The seeds are either broadcast, drilled, or dibbled by hand and are mixed with sand, ash, or fine soil to facilitate sowing. The seeds are sown either in ridges or a flat bed.

In any case, a shallow furrow is made 30-45 cm in length. When the seeds are dibbled, they are sown with 7.5-10 cm spacing. With such conditions about 4- 6 kg of seeds is needed per hectare.

Then seeds are lightly covered with soil or sand. Some growers irrigate the field about 24 hours before sowing to ensure that adequate moisture is present at the time of sowing. Many varieties germinate in about 10-15 days.

Fertilization management in Carrot farming

Fertilizer recommendations should be based on soil analyses.

Farm Yard Manure at the rate of 30 tonnes per hectare is applied at the final ploughing and dosage of 40 to 60 kg nitrogen, 25 to 50 kg of phosphorus and 90 to 110 kg of potassium per hectare is recommended has basal dosage

2-3 tons of farmyard manure at the time of land preparation along with 50 kg nitrogen, 40 kg phosphorus, and 50 kg potash per hectare.

Half the dose of nitrogen and the full dose of phosphorus and potassium should be applied before sowing. The remaining nitrogen should be given 56 weeks after germination.

Carrot is a heavy potassium feeder. Potassium deficiency can affect the quality of the roots in addition to disturbing the overall metabolism of the plant. Potassium-deficient roots are less sweet, and the flesh does not have the desired luster.

Irrigation

The first irrigation should be light and carried out immediately after sowing. Subsequent irrigations are given as needed.

Too much moisture causes short carrots with light colour and a larger diameter. The frequency of irrigation depends upon soil type, season, and variety.

In general, one irrigation every 4-5 days in summer and 10-15 days in winter provides adequate moisture for the crop.

During the rainy season, only occasional irrigations are needed. Water stress should be avoided during root development to prevent cracking of the roots.

Intercultural Operations

Weed control
Weeds compete with the crop; therefore, Weeds can be controlled mechanically, by hand, mulching and chemically or by combining all these methods.

Earthing up:

CarrotShould be done at 60 to 70 days after sowing to help in the development of roots the soil is earthed up covered the top of developing roots to prevent loss of colour of tops, the tops become green and toxic when its exposure to sunlight.

 Harvesting

Early carrots are harvested when they are partly developed. For distinct markets otherwise, they are retained in the soil till they reach full maturity stage they should not be retained full maturity stage because they become hard and is unfit for consumption.

Carrots are harvested when the roots are about 1.8 cm or larger in diameter at the upper end. The soil may be loosened with a special plough (carrot lifter) or an ordinary plough.

The field is irrigated once a day before harvesting to facilitate harvest.

After harvesting, the carrots are placed in a packing house in crates before washing. After that carefully wash Carrots and sort by size before packaging.

Yield

Carrot yield is deferring varies to the variety. In tropical types varies it give around 20 to 30 tonnes per hectare and in temperate type variety may give 10 to 15 tonnes per hectare.
