Growing KT2 potatoes on 2-crop land

KT2 potato variety was created by Center for Research of tuberous plants - Institute of Food Plants - food plants. Through SX wide area in Ha Nam province, we have some introductory intensive experiences for reference readers:

(Photo: osmotek.com) KT2 potato variety has a growth time of 85-87 days, healthy growth, average yield of 22-25 tons of tubers / ha, high intensive cultivation of over 30 tons / ha. Yellow commercial tubers, eat boldly, make sure meat is suitable for consumers' tastes. The planting season from October 15 to November 5 is the best, while ensuring productivity and freeing land for spring rice cultivation.

Seed preparation: Depending on the amount of tubers and the quality of the sprouts in the tubers, the amount of seed is from 30-35 kg of tubers for 2 Northern sao. Before planting, you need to sort the size of tubers. If the big bulb has many sprouts, use a sharp knife to make a piece to make sure each piece has 2-3 sprouts, each time it is necessary to dip the knife into lime water to avoid spreading the disease from one root to another. Cut the tubers of the tubers and immerse them in the kitchen ash.

Soil preparation: Should be planted on 2-crop soil, regular beds with 2-3 cm of water will help to reduce soil and ensure enough moisture for favorable growth of potato, especially in the root-making period. Place the soil on 1.2m wide double beds, 20-25cm high.

How to plant: Make 2 rows on the double bed surface, each row is 10-15 cm from the edge of the bed. Spread the manure into the canal, then place the seedlings or seed pieces 30 cm apart, requiring the tubers to not be in direct contact with the manure, then fill the soil with 5 cm thick roots. With planting distance as above, planting density needs 5-6 tubers / m ² .

Fertilizer: Amount of fertilizer for 1 ha

- Manure: 20-22 tons.
- Urea fertilizer: 250-260 kg.
- Phosphate supe: 555 kg.
- Stool of kalicloride: 240 kg.

Applying all animal manure and phosphate.

Top dressing: Applying nitrogen + 1/2 amount of potassium combined to pick up bed surface grass, use mud or wet soil under the furrow cover.

Top dressing 2: After 20-25 days after planting, apply the remaining nitrogen and potassium. Use a wet soil under a high trench, covered with fertilizer. With such a way, there is no need to cultivate and limit labor but still suitable with the way of growing potatoes on wet soil (regular water ditches). When applying fertilizer, apply away from the root.

Pests and diseases : Note green worms, thrips, spiders with Regend 800 WG drugs, 5SC Ortus. Downy mildew, root rot .

Harvest : When 1/2 stems, leaves turn yellow, before harvest 7-10 days stop watering, harvesting sunny days, tuber sorting and keeping cool place.
