Since corn is a demanding thermophilic plant, the gardener will have to make sure that the temperature, acidity and humidity of the soil correspond to the parameters necessary for the full growth and development of the plant. The amount of nutrients in the top dressing depends on the phase of culture development.
Corn grain contains 65 – 70% carbohydrates, 9 – 12 % protein, 4 – 8 % fat, 1.5 % mineral salts, 2.5 % fiber, vitamins and 14 – 15 % water. Grains are used to produce flour, cereals, flakes, canned food (sweet corn), starch, ethyl alcohol, dextrin, beer, glucose, sugar, molasses, syrups, honey, corn oil (grain germs contain up to 30% fat), vitamin E, ascorbic and glutamic acids. Unripe cobs are eaten raw, boiled and canned. Pistillate columns are used in medicine. Stems, leaves and ears can be used for the production of paper, linoleum, viscose, activated carbon, artificial cork, plastic, anesthetics.
