To get a good harvest, you must choose the right planting site and follow the rules of agricultural technology. Let's consider these issues in more detail

Soil preparation and predecessors

The best predecessors are tomatoes, root vegetables, legumes, melons and early cabbage. In the fall, after harvesting these crops, the soil is filled with rotted manure or compost with the addition of 30 g of superphosphate and 15 g of potassium salt per square meter. Then dug to a depth of 20 cm.

If the soil is acidic, then dolomite flour is added in the fall, in the amount necessary to create a neutral environment. In the spring, ash is scattered and re-dug to a shallow depth.

Seed selection

Before sowing, select full-bodied, healthy, undamaged grains. To improve germination, they are pre-soaked in water for a day to saturate with moisture. Or they are kept for several days in a wet cloth in a closed container and in a warm place. When small roots are formed, they are planted in the ground.

Corn cultivation is carried out in two ways:

• direct sowing into the soil;

• through seedlings.

Growing seedlings

This method is used in the middle lane and northern regions. Where the growing season is short and there are not enough days with optimal temperatures for growth. When getting an early harvest, they resort to the same method.

Seedlings are grown in film greenhouses, greenhouses or at home on windowsills. For these purposes, use cassettes, cups or a common container.

It is better to select the soil purchased on the basis of peat and mineral fertilizers. You can prepare it yourself by mixing humus, garden soil and sand in a 2: 2: 1 ratio. Adding complex mineral fertilizer Kemiru or nitroammofosku 20g per bucket of mixture 10l.

Soil is poured into a medium-sized box, moistened, and evenly germinated seeds are laid out at a short distance from each other. Then fall asleep on top of the earth with a layer of 1, 5 cm, pressing it tightly.

2 grains are placed in separate cups and cassettes. After germination, a stronger one is left, and a weak one is cut off without damaging the root system.

Containers with seeds are covered with foil and placed in a warm place until shoots appear. During this period, additional watering is not required, the film retains moisture inside.

Shoots appear in 1-2 weeks. Sprouted seeds germinate faster than dry seeds. They are gradually accustomed to the open air for several hours a day, opening the material slightly. Then remove it completely.

In the phase of 2 leaves, seedlings are fed with the complex fertilizer "Kemira Lux" at the rate of 1 teaspoon per 5 liters of water. When the threat of recurrent frosts has passed and when 3 leaves are formed on the plant, they are planted in open ground, slightly deepening the stem. The age of the seedling itself reaches 3 weeks by this time.

Sowing in open ground

When the ground at a depth of 10 cm warms up to 10 ° C, the seeds are sown in 2 ways:

• private;

• square-nested.

In the first case, the row spacing is left 45 cm wide, and in a row - 40 cm. With a square-nested one - the landing pattern is 50x50.

On the bed, grooves are cut with a depth of 6 cm, spilled with water and the seeds are laid out according to the scheme. So that there are no empty places, 2 seeds are planted in one hole. They are buried in earth with a layer of 2 cm.

In the phase of 2 true leaves, the seedlings are thinned out, leaving 1 strong stem each. In the process of growing, the soil is added to the plant so that the formed aerial roots become real and develop well.

Growing and caring

At first, seedlings grow very slowly, so they need to be weeded regularly. Otherwise, the weeds will not allow the seedlings to grow, taking away food, light and water. The grown corn can deal with weeds on its own. It forms such powerful roots that it practically takes all the moisture from competitors.

To minimize evaporation, soil mulching is used with improvised material. Suitable for these purposes: cut grass, weeds without roots, sawdust, peat. It is laid out after watering with a layer of 5-10 cm. It not only covers moisture, but also keeps the soil loose and prevents many weeds from sprouting out.

Top dressing with complex fertilizers is carried out 2 times per season after preliminary moistening. 15 g of "Baikal" or "Kemira Lux" fertilizer are dissolved in 10 liters of water. Watered with 1 liter for each plant. The first feeding is given in the 4-leaf phase, the second during flowering.

Moderate watering is required in dry weather. It is carried out rarely, but in sufficient doses, preventing the top layer of the earth from drying out.

Cleaning

It is carried out as the ears ripen in several periods. To determine readiness, pay attention to the color of the threads. When they turn dry and brown, the ear can be plucked.

To use it for food and processing, it is harvested in the phase of wax and milk ripeness, for seeds - at full maturity.

Corn grown in the country is an environmentally friendly product, useful in all respects.
