Corn: planting and care in the open field

Corn: planting and care in the open field

Almost everyone remembers what kind of culture used to be called the “queen of the fields”. So at a certain period in our country they called corn. And all because it began to be zoned in almost all corners of our vast country. And until now, the taste of summer is associated with the taste of a ripe, slightly salted golden natural delicacy. Many summer residents successfully grow this satisfying cereal on their own.

Variety selection

Not every variety is tasty when consumed boiled. There are varieties used only for conservation, processing or for the production of feed for livestock and poultry. Corn is an annual plant that has seven subspecies.

In our agriculture, the most widespread are such as sugar, flint and tooth-like. In America, the most popular are starchy and bursting. The least known subspecies are waxy and hulled corn. Each of these subspecies is divided into varieties.

When choosing them, you should find out what the ripening period of the variety is, the shelf life, the size and color of the grains, and the taste.

Sugar or vegetable corn

Its grains have improved palatability, because they contain water-soluble sugars. You can use boiled and canned corn for consumption. This subspecies has many hybrid varieties.

  • "Lakomka 121". It can be distinguished by its high yield, disease resistance. Boiled grains are juicy and sweet. The plant is stunted - the maximum reaches a height of one and a half meters.
  • "Aurika". Early ripe hybrid. Bright yellow grains of large size. They have a thin skin and a delicate inside. They can be used for consumption in any form: fresh, for cooking, canned and after freezing.

Siliceous

The kernels of this corn are used to make flour. They make excellent cereals, as well as healthy foods such as flakes and corn sticks. By the white and yellow color of the grain, by the smooth and shiny appearance, by the convex top, they can be distinguished from other subspecies. But there are varieties with a different color.

  • "Pioneer". With increased yields, it differs in that after cooking, corn is tasteless. More often it is planted for the preparation of animal feed and for the purpose of subsequent processing.
  • Cherokee Blue. It is a high yielding and early maturing variety with a medium grain size. The color of the ripened grains is lilac-chocolate. Differs in excellent tastes in a boiled look.

dentate

It is used as food for domestic animals, as well as for the production of alcohol, flour and cereals. It has a variety of colors and a long grain with a deepening, similar in shape to a human tooth. The grain size is large. It includes the following varieties.

  • "Syngenta". This hybrid is characterized by cold resistance and the presence of many useful elements in the composition. Corn grits are obtained with a high content of trace elements and nutrients. Goes to forage.
  • "Dneprovsky 172 MV". Mid-season hybrid. Equally immune to cold and drought.Used to make flour, cereals and livestock feed.

starchy

Starch, flour, molasses and alcohol are made from this grain. In appearance, the grain is dull and with a convex top. Inside the grain is loose and powdery.

  • Mays Concho. It is an early and high yielding variety. The color of the grain is bright yellow, it is large in size, soft to the touch, slightly sweet in taste. It is used for cereals and cornmeal.
  • Thompson Prolific. The variety is high-yielding, since 3-4 ears are tied on one plant, and quite large ones. In appearance, the variety can be recognized by the flat large white grain. It is used to make flour of the highest grade.

bursting

This is the raw material for popcorn, as the grains burst when heated, which is the main feature of this subspecies. The grain is shiny and smooth. This subspecies is divided into the so-called rice and pearl barley groups. They are divided based on appearance and taste.

  • Oerlikon. It has a high sugar content. It makes delicious popcorn, large and elastic.
  • "Red Arrow". Early maturing and high yielding variety. Grain of maroon color of an oval form. Used to make popcorn and cereal.

waxy

Corn is named so because it resembles wax. She has matte and smooth outside, and mealy and sticky grains inside. It has a small number of varieties.

  • "Oaxacan Red". The color of the grain is bright red, the size is medium, the taste is sweet. It contains many nutrients, it is suitable for both flour and cereals.
  • "Strawberry". The grain is dark red, pointed at the end, similar to a grain of rice.The variety is universal: in the period of milky-wax ripeness it is very tasty boiled, and in the period of full ripening it is used for making flour and cereals, as well as for making feed for livestock.

membranous

            This corn has no nutritional value. It is grown as fodder, as spikelet scales grow and densely cover mature grains. Therefore, the green mass is used for silage, and the grain - only for livestock feed.

            Timing

            Corn is a heat-loving cereal, so it is advisable to start planting it in open ground only when the threat of frost has passed and the soil temperature will be at least +10. A decrease to +3 degrees Celsius and below is detrimental to her. Across the country, planting dates depend on the temperature characteristics of each climatic zone.

            Residents of the southern regions begin planting in late April - early May, for the middle part of our country, the optimal time for planting is mid-May.

            Some cold-resistant hybrid varieties can be planted in early May. In Siberia and in the northern part of Russia, it is desirable to grow this sissy culture using seedlings. Sowing for seedlings occurs at the beginning of May. In mid-June, seedlings are transplanted to a permanent place of growth.

            Growing technology

            To get a rich corn crop, pick up a sunny, wind-protected place. Optimally, when it grows on light soils, moderately moist and enriched with nutrients. Before planting, you can independently enrich the soil by applying mineral and organic fertilizers.

            Landing in open ground is carried out according to the classical or square-nested pattern.

            • In the classical scheme, seeds should be planted in rows of 2 pieces in each hole at a distance of 35-40 cm. Row spacing is 40-50 cm in size.
            • With the square-nest method, seeds are planted at a distance of 45 cm in all directions. It is necessary to plant 3 grains in a hole, germinate and leave the strongest sprout.

            Using any planting scheme, each of which is also suitable for growing corn in a summer cottage from seedlings, it must be remembered that it is undesirable to grow it in one single row so that there are no problems with cross-pollination and tying ears on crops.

            Also in the summer cottage, you can apply the scheme of joint crops of corn and climbing plants. This saves space for planting in the country. Cucumbers, beans or peas grow based on a natural frame - straight and tall corn stalks. Legume seeds - peas and beans, can be planted immediately in pits with corn grains, and cucumber seeds need to be germinated 30 cm from the corn stalk. In order for this method to help grow strong and well-bearing plants, it is necessary to additionally apply organic and mineral, especially nitrogen, fertilizers to the ground.

              If you plant a corn seed several times with an interval of 2 weeks, then this allows you to grow a crop several times over the summer, especially if you use varieties of different cultivation periods in the garden.

              The depth of planting seeds depends on their preliminary preparation. On a pre-prepared summer cottage, holes or rows are made according to a specific growing pattern to a depth of no more than 7 cm. If the grains were prepared in advance - sprouted and swollen, then they are closed to a depth of 3-4 cm, if they are dry, then they are planted deeper.

              It is better to plant grains in spilled soil and sprinkle it with wet soil, and then with dry soil. 14 days after the seeds are planted, the first sprouts hatch.

              Planting material preparation

              Before planting, it is advisable to prepare the material for planting, inspect and remove damaged non-viable seeds. Grains can also be tested for germination - put them in a 5% saline water solution, soak for up to 5 minutes. Grains that have fallen to the bottom of the container are suitable.

              Grains suitable for planting in open ground begin to be prepared 8-9 days before the start of sowing. Initially, they are heated for 4-5 days at +35 degrees Celsius (in the sun, on a battery), and then they are kept in warm water for 1 to 3 days until germination. For soaking, it is better to spread the grain on paper or in a cloth bag, and not leave it in water to avoid rotting. You can also germinate the seeds on a substrate moistened with water - on cotton or gauze, and make sure that it does not dry out.

              Experienced summer residents advise soaking grains in a solution of wood ash. This contributes to rapid germination and saturation of the grain with useful minerals. A cloth or gauze bag is filled with seeds and kept in an aqueous solution of ash. The water should cover half the seeds. Every day until germination, the aqueous solution with ash is mixed.

              To protect the seedlings from fungal diseases, you can additionally treat the planting material with a fungicide or potassium permanganate solution before soaking, holding it in it for up to 20 minutes.

              Soil treatment

              It is advisable to start preparing for planting at their summer cottage in the fall. You can prepare a piece of land on which potatoes, cabbage, legumes, tomatoes, zucchini, pumpkins were previously grown.It is undesirable to grow corn in millet fields, as they have a single pest - the corn borer.

              In autumn, it is desirable to carry out deep tillage: digging with the addition of organic fertilizer - manure or humus, and in the spring, the day before planting, add mineral fertilizers, better nitrogen-containing, for example, nitrophoska.

              Care rules

              Corn, even for inexperienced summer residents, is not a difficult crop to cultivate. But it also requires care and knowledge of the secrets of its cultivation.

              After planting seedlings or germination of seedlings, you need to take care of them - often water, weed and be sure to spudso that adventitious roots grow in the corn at the bottom of the stem, which give the stems strength and full development. You also need to loosen the ground, feed the seedlings, and, if necessary, treat the land with herbicides. Of course, their use in weed control is more justified in the fields and during mass plantings, but you can also use selective preparations in your garden that selectively affect only weeds and provide maximum protection for corn seedlings.

              If corn lacks pollination, then it can be helped. It is necessary that pollen gets on the inflorescences, only in this way new cobs are tied. To do this, you need to pick panicles from the top of the stem and shake them over the cobs.

              To increase the size of the cobs and their number during the growth of the plant, stepsons must be removed. If you do not remove these side shoots, then even just the growth of plants upwards will be delayed.

              Watering

              Corn is a moisture-loving crop. However, an excess of moisture is harmful to it - due to lack of air during overflow, its roots die off, it stops growing, and the leaves have a purple hue.Therefore, the optimal water consumption is 1-2 liters per adult plant. If it is not possible to regularly water the crop, then you need to loosen the ground around the plantings more often so that moisture remains in it longer. No wonder loosening can be compared with dry watering.

              When the seedlings are still small, they do not need to be watered often and plentifully. But when there are already 7 leaves on the stem and until panicles appear, corn needs frequent watering within the water norm for an adult plant. From the time the stigmas darken - the threads on the cob, watering can again be reduced.

              Modern summer residents use drip irrigation systems. This significantly reduces water consumption and the amount of fertilizer diluted in it, since it goes directly to the very root of the plant.

              top dressing

              In order for the plants to develop well and give a bountiful harvest, they are fed with organic and mineral fertilizers by applying them before planting and during growth. Since corn differs from many cultivated plants in that during the entire period of its growth and maturation it must also increase its green mass, certain fertilizers must be applied throughout its entire length in order to ensure uniform development of both the greens and the cobs themselves, and to improve the taste. and useful qualities of the crop.

              Nitrogen fertilizers are added to the soil before the grain ripens, moreover, the maximum amount of nitrogen should be given to the plant during the period when inflorescences form on it. Potassium-based fertilizers are best applied at the beginning of the growing season, when the seedlings absorb them the most. After that, this action will no longer be effective, since there is a reverse outflow of potash fertilizers from the seedlings into the soil.

              The need for phosphorus in corn is not so great, but it is necessary throughout the season. Therefore, phosphate fertilizers begin to be applied even at the stage of preparing the land for planting, and finish after the cobs have ripened.

              Maize also needs trace elements such as manganese, zinc, boron and copper. If the earth in the area is alkaline, then there is a lack of manganese and boron, if acidic - calcium. Fertilize with foliar irrigation.

              The first feeding occurs when there are 3-4 leaves on the stem. They are watered with bird droppings or slurry dissolved in water. For the second top dressing, a mixture of ammonium nitrate, potassium salt and superphosphate is used. The required dosage is 15-20 grams of ammonium nitrate, 15-20 grams of potassium salt and 30-50 grams of superphosphate per square meter.

              If during the growing season the plants show signs of a lack of some specific trace elements, then they can be replenished by spraying or processing the leaves of the plants. White stripes on the leaves indicate a lack of zinc, and if the ovaries are delayed, you need to make up for the lack of boron.

              If the leaves turn pale and the plant does not grow upward, then this indicates a lack of nitrogen. The leaves become purple in color - this indicates a lack of phosphorus. Brown leaves with wavy edges indicate a lack of potassium.

              Diseases and pests

              A variety of diseases and pests interfere with the normal development and formation of a full-fledged crop. The most common diseases.

              • Fusarium cobs. On the grains, starting from the time of milky ripeness, a pinkish bloom appears. The grains begin to darken, loosen, lose their luster and smoothness, and collapse.Even if some appear intact, they may be infected and not suitable as inoculum. The most common cause of Fusarium is high humidity due to frequent rains. To protect plantings, the seeds are treated and dressed at the stage of preparation before sowing.
              • Fusarium seedlings. Seeds are affected by a white or pink bloom, so a weak sprout appears from them. It either turns brown and dies, or grows into a plant lagging behind in development with weak roots, a thin stem and dry leaves. There will be no ears on this stem, so it is better to remove it from plantings. A preventive measure for the disease will be the treatment of seed with fungicidal preparations, as well as the observance of planting dates and the choice of a suitable site - sunny and warm.
              • Helminthosporiasis. With this disease, brown and gray oval spots with a dark border appear on the leaves and cobs. In the center of these spots there is a black coating. These spots spread throughout the plant and leaves, cobs and grains rot. The causative agents of this disease remain for a long time in all parts of the stems and cobs. Measures to combat them are competent crop rotation, cleaning of weeds and residues of green mass after harvesting, selection of hybrids resistant to helminthosporiasis for planting, as well as treatment of planting material and land with fungicides.

                Of the pests, the following are known.

                • Wireworm and false wireworm. The wireworm is the larva of the click beetle, and the false wireworm is the larva of the dark beetle. They gnaw holes in the underground part of the stem and can thin out crops. They are activated at low temperatures and in a humid environment.To protect the crop, control measures such as digging up the earth in the fall, using crop rotation, treating the seed grain with insecticides, and using pheromone traps during the growing season are used.
                • Owls are leaf-eating. Destroy parts of plants that grow on the surface of the earth. During the season, winter, meadow and cotton scoops reproduce from 2 to 4 generations. Scoops, as well as their larvae, first destroy the leaves, then the cobs. Methods of dealing with them are mainly agrotechnical - crop rotation, tillage in the fall, weed control. Larvae can be destroyed using pheromone traps.
                • Swedish oatmeal. It also destroys all parts of the plant and multiplies 2-3 times during the summer. To prevent its occurrence, you need to deeply dig the site in the autumn, carefully destroy weeds and observe the planting dates. When this pest is already on the site, then it is necessary to fight it with the use of insecticides.

                Pests such as meadow and corn borers are also known.

                Harvest and storage

                Sweet corn is harvested when the cobs reach milky maturity. This can be seen in the following signs:

                • the color of the inner shell of the cob becomes light green, and the outer shell has dried;
                • threads of the cob are dry and brown;
                • when compressed, the grains emit a white liquid;
                • the grain is smooth, whole, no wrinkles are visible on it.

                When the ears are overripe, they will lose their taste, the grain will become hard and shriveled.

                Cobs for cooking can be stored in the refrigerator at 0 degrees for no more than 21 days. If you store them at temperatures above zero, they lose sugar, and, accordingly, their taste properties. Therefore, it is better to keep the corn crop in the freezer on the cob.

                Peeled cobs should be dipped in boiled water for 2 minutes, then in a container with ice for 2 minutes, then dried well on a cloth, wrapped one at a time in food film and folded into the freezer. So they can be stored for up to one and a half years with the preservation of all taste qualities.

                To ensure the preservation of corn for a long time, you need to clean the cobs of debris and dry. Only undamaged specimens are suitable for this type of drying. Leaves and thin threads (corn stigmas) are removed from them, but the wrapper is left. With its help, cobs are braided into braids and hung in a dry room with good ventilation. When the seeds can be shaken out of the corn cob with light shaking, drying can be completed.

                For long-term storage, the grains are husked and put into plastic or glass containers, boxes or bags. Popcorn grains should be stored in a plastic bag in the freezer. They can be used immediately without defrosting for cooking.
