Techniques for growing carrots for high yield and outstanding quality

Carrots are the most commonly used vegetables in Vietnamese cuisine. If you are looking to grow carrots, you can refer to Techniques for growing carrots the latest, for the outstanding productivity of Agri.

The carrot plant, scientifically known as Daucus carota subsp sativus, is a bulbous plant, usually yellow-orange, red, yellow, white or purple. The edible part of the carrot is the tuber, which is actually the main root of the plant, which contains many precursors of vitamin A, which is good for the eyes.

Planting season

Carrots are planted from August to early February next year, harvested from November to May next year and can be divided into 3 teas as follows:

  • Early tea sows seeds from: early August to October 15, harvest from November
  • The main tea sowing season is from October 16 to December 15, harvested around the Lunar New Year
  • Late tea is sown from December 16 to January 30 next year, harvested until May.

Breeding technique

There are many varieties, but growing mainly 2 hybrid carrot varieties are Super VL-444 F1 and Ti-103. This variety has a growing period of 100-130 days. The average yield is 1.5 tons / pole, higher can reach 3 tons / pole.

Techniques for cultivating carrot soil

Should choose alluvial soil along the river is light soil, sandy soil or alluvial soil to grow carrots is best. The land must be cleared of weeds, then thoroughly plowed, finely milled, leveled and then raised into beds. The width of the beds is from 85-90cm (early tea) and 80-85cm (main season tea and late tea); height 20-25cm; groove 25-30cm wide.
After leveling the bed surface, draw 3 rows on the bed surface lengthwise and about 5cm deep, rows from 13-15cm apart. (If sowing by machine, the machine will align itself).

Seeding technique

Early-season tea sown from: 100-120g/pole; main crop: 100g/pole; late crop: 70-90g/pole;
Soak the seeds in water for about 8-10 hours, then incubate for 1-3 days. Seed incubation should be applied in the late crop because the low temperature makes it difficult for seeds to bloom; For quick seed germination, seeds can be buried in warm ash or placed next to the stove. It can be incubated for 5-7 days when the seeds sprout. Before sowing, wipe the seeds until they are almost dry, then mix the seeds with white powdered soil or lime powder for easy identification when sowing.

Seeds can be sown by machine or by hand, sowing in a recessed pattern, the hole is 3cm away from the hole; 1-2 seeds in each hole. If sowing by machine, do not incubate seeds with long roots, because so the seeds will fall unevenly.

Should be mixed with clean sand or kitchen ash to sow evenly after soil preparation. After sowing, cover with straw or hay or 1×1 mm nylon net, watered every day.

Techniques for growing carrots and caring for plants

When the plants grow evenly, prune away weak, stunted or overgrown plants. Before the third application (or the last time in the rainy season), prune the trees (combined with weeding) with a distance of 20x20cm in the rainy season, 20x15cm in the dry season.

Watering: Use unpolluted water sources, well water, upstream spring water, do not use wastewater, stagnant pond water, stagnant water for a long time.

If sowing in the rainy season does not need to be watered, but sowing in the dry season is watered twice a day until it grows evenly, then depending on the soil moisture, water it appropriately to ensure enough water for the plants.

Weeding: Carrots require long-day light, so weeding beds should be cleaned to focus light for plants.

Techniques for fertilizing carrots

Fertilizer: The amount of fertilizer materials calculated for 1 hectare/crop is as follows.

– Farmyard manure: 40 m3; Lime: 800-1,000 kg; organic microorganism: 1,000 kg.

– Chemical fertilizers (pure amount): 150 kg N, 150 kg P2O5, 240 K2O.

Pest control for carrots

There are gray worms using drugs such as Abamectin, Cypermethrin to prevent, with the dosage recommended by the manufacturer.

The caterpillars clean the fields, prepare the soil thoroughly before planting, use sweet and sour baits to catch butterflies, remove the nests of eggs, and kill newly hatched caterpillars.

Aphids prevent by watering to keep plants moist in dry season conditions. Can use some active ingredients Thiamethoxam, Imidacloprid to prevent.

Ring spot disease should treat seeds before sowing with hot water at 500C for about 30 minutes. Use active ingredients Chitosan 2% + Oligo- Alginate 10% (2S Sea & See 12WP), Oligo-Alginate (MA Maral 10SL) to prevent.

Powdery mildew disease requires early collection and destruction of diseased plants. Use active ingredients Trichoderma spp + K-Humate + Fulvate + Chitosan + Vitamin B1 (Fulhumaxin 5.65SC) to prevent.

Leaf blight (in the period of 45-50 days of SKT) use Bordeaux (50gr CuSO4 + 50gr lime paste) or Derosal 20cc/10 liter.

Black rot is caused by Alternaria radicirima and dry rot is caused by Pronarostrupii sp. These fungi damage both stems, leaves and tubers.

Implement control by drugs such as Plant 50WP (20-30g/10 liters of water), Derosal 50SC (15-20ml/10 liters of water); Kocide 53.8DF (20g/10 liter water), Cuproxate 345SC (20-25ml/10 liter water).

Harvest and store carrots

When the foot leaves turn yellow, the young leaves stop growing, then harvest. Should not be too old, the quality of the product will decrease. Minimize the construction of tubers. Sorting, packing, shipping according to customer requirements.

If you need a beautiful design, right after harvesting, choose beautiful tubers, wash the soil by spraying with tap water, treat for 1 minute in 1% calcium hypochlorite solution or 2% filtered lime water. Rinse with clean water. Avoid damaging the tubers during processing, dry the skin thoroughly before packing.
