Experience in growing sweet corn

Sweet corn has a short growth period (67-85 days depending on the weather). The tree is 2-2.2m tall, the position of corn is low, so the resistance is good. Sweet corn is grown all year round, giving high yield from 650-800kg / Northern pole. In addition to collecting corn, sweet corn also gives a green food amount of 2.5-3 tons / rod. High disease resistance.

Prepare soil

Sweet corn has a wide adaptability, the more fertile soil gives higher productivity. Just choose the land that is not flooded, near the water source to be proactive in providing adequate water in the process of growth and development. Sweet corn soil requires 18-20cm deep plowing, cleaning grass, harrow flat, up beds.

Drills

Planting density depends on the season and fertility of the soil, planting with a density of 1,600-1,800 trees / Northern pole is best. Every row is 65-70cm, the plant is 25x30cm away from the tree. 1kg of sweet corn cultivars 4.5-5 sao Northern (8,000 - 9,000 seeds / kg).

How to sow

It is possible to sow sweet corn seeds directly to the ground without composting. Sow seeds deep 2-2.5cm. After sowing, water very moist until seeds germinate. Just sow 1 cavity 1 seed. Notice the precaution . There are places where people put seeds in a damp cotton towel, wait for the seeds to sprout to bring them to grow. But through practical experience, the method of incubating seeds in moist sand is the best. The germination of the sweet corn is slow, only 4-5 days of germination. To ensure the density of 5% of seed need to be sown, should be sown 1 day before.

Take care of

Taking care of sweet corn fields after sowing to harvesting, is like taking care of other corn varieties that farmers are growing. For high productivity, avoid the risk of losing plants, and avoid the uneven development of corn fields.

Fertilizing

Applying manure with manure with the amount of fertilizer needs 500kg / rod. Phosphate fertilizer 12-15kg / rod. Nitrogen fertilizer 3-4kg / rod. Dressing:
- First time: When corn 3-4 leaves apply 3kg N + 2kg K / rod;
- Second time: When corn is 7-8 leaves, apply 3kg N + 2 kg K / rod;
- 3rd time: When 10-11 maize leaves, apply 3 kg N / rod.
The amount of fertilizer and fertilizer also depends on the state of land and local practices. The acidic areas (pH = 4.5) need to be lined into the grooves or recesses 30-40kg lime / rod.

Sprinklers

Water is the most important factor for sweet corn. The best sowing period is 50%. When a 3-4 leaf tree needs watering to keep the plants moist, it is possible to combine dilution of fertilizer to irrigate. At 7-8 leaves the plant watered enough moisture 70%. Note at the stage of the speaker twisting, finish the last time, raise it high and carry out watering. If this water is watered to ensure enough moisture, the yield can increase by 15-20%. Pest and disease control: Prevent pests for sweet corn like other corn varieties.

Harvest

Unlike the regular corn varieties, the harvest time of sweet corn is very short, only in 2-3 days. When the corn grain is full, it is orange, the beard slightly shrinks, then harvest. If grown for processing, harvesting is determined by the processing establishment. Note: Plant sweet corn to avoid stubble and stubble meeting weather above 37 ^o C and below 15 ^o C. Only 1 corn / tree is needed.
