Originally from America, was one of the first exports to Europe made the continent.Today, corn is very popular in almost everyone. Apart from the valued properties of cereal, with its full nutritional content, corn is a delicious ingredient for salads, stews or simply to enjoy it with butter.And the tamales or the cake will be much richer for you and your family prepared with corn removed from his own garden. Although that's the way we usually use, is also very important in animal feed grain for pigs and poultry dry and silage for livestock. For many applications, this grain is cultivated from northern Spain to the far south, in the Tenth Region, provided that conditions are presented and appropriate water temperature.
Tending the corn
Corn has a developed root system, requiring a deep soil rich in nutrients, but also adapts to thin soils, with good fertilization and wetness. Once prepared the ground, but before sowing, watering is recommended to ensure good conditions, thus delaying the first irrigation.On the other hand, stimulate germination of weeds, allowing an operation to remove rastraje to prevent then to develop, compete with corn. It is sown in spring, after last frost.The crop should be in rows 60 to 80cm apart, putting 3 0 4 seeds every 40cm and about 5 to 8cm deep. To germinate, corn requires a soil temperature of at least 12 degrees, which in the central region can be achieved as early as spring, and varies depending on the area of the country. What you will not forget is that the corn does not tolerate frost, so make sure that the climate "is strong" not to surprise us one to spoil the plantation. In regard to water needs, maize poses the greatest requirements between the formation of the panicle and upper stem of the cane and the appearance of grain.The frequency of irrigation depends on soil, but generally in the central area, ranging between 10 and 12 throughout the season. For the time of harvest of corn, some ecocultores leaves open a little sheath that surrounds it (husk) and check the degree of development of the grains.Others are guided by the color of "hair" of corn and says that when they go from gold to brown, the corn would be ready to harvest.You will have to resolve, through personal experience, which method is most effective. If you buy hybrid seeds, the packaging indicated the growing period of the plant and, therefore, the time of ripening corn.
Weeds affect the corn crop
The first step in weed control and we describe it, later you can use manual or chemical methods or a mixture of both.It is important to control them, as higher losses in yield caused by weed competition in the first third of growth, from start to emerge until 40 0 60 days later. With regard to chemical control, herbicides should be used basically depend on the type of weed and time of the attack, and can be applied before the planting until after the emergency. Those that are commonly used are Paraquat, Dicamba and EPTC, among others.
The doses and types of fertilizer will depend on the ground, so it is advisable to do a soil test that clearly indicated the shortcomings of the land in relation to the needs of corn. Anyway, some say experienced ecocultores gives excellent results add about 300 units of nitrogen per hectare, either before planting or applied in two parts, the second after 30 days of the first applied.Alternatively, ask for advice from a neighbor who already have experience in the field.
