Sowing corn, 0.5 kg

corn - a tall one -year -old grassy plant, reaching a height of 3 m or more. The corn has a well -developed uterine root system that penetrates to a depth of 100-150 cm. Air supporting roots can form on the lower nodes of the stem, protecting the stem from falling and supplying the plant with water and nutrients. The stem is erect, up to 4 m in height and 7 cm in diameter, without a cavity inside (unlike most other cereals).
