Soil preparation:

It requires warm, humid soil well ventilated and very fine. There are 2 types of systems soil preparation.

Mechanized: Plowing is intended to loosen the soil and incorporate waste as well as to combat weeds and pests. It is recommended to perform this work in advance to planting. These tasks provide the sowing, fertilization and application of insecticides and herbicides.

Minimum farming: in areas with a steep slope, it is recommended the use of minimum farming or zero. Where soil is almost not altered and will help minimize the risk of erosion.

In our area, due to the land nature, we prepare the ground in a minimum farming.

The Density of planting:

It means the seeding rate to the number of plants per area, here would be the number of plants of corn in a hectare. Densities of 50,000 – 55,000 plants per hectare are used in commercial plantings.

Sowing distance:

  • The planting distances and the number of seeds per hole determine density and the amount of seed to be used.
  • The distances are: the distance between rows and the distance between plants.
  • The recommended planting distances are: 0.75 m. between rows 0.50 m. between plant two seeds per hole for planting with a macana (wooden or steel tool for make holes).

Manual harvest:

Usually, before the harvest begins, it is common practice to leave the corn in the field attached to the plants for a variable time and with this process the grain is dried gradually.

Among the most commonly used practices we could mention:

  1. Leave the entire plant standing when they have developed.
  2. Cut the top of the plants, to allow a greater exposure to the Sun.
  3. Bent or broken. This procedure consists in doubling the top plant or the corn cob. This practice is intended to prevent rain from entering the interior of the corn cob and decrease the damage from birds.

If after physiological maturity, the climatic conditions are high relative humidity, with frequent rains, insects, birds, rodents and other pests. Also, susceptible varieties are cultivated at these factors, losses which arise at this stage can be of great consideration.

The harvest or separation of corn husks of the plant is carried out in two ways with and without leaves.

Once the cob has been cut depending on the moisture content, it is customary:

  • To continue the drying process that began in the field after physiological maturity.
  • Store them with or without leaves.
  • Threshing

Forms of drying

When it is necessary to continue the drying process depending on the existing facilities, this is exposing the corn cob to the sun on patios. Farmers that have a more technical infrastructure, use dryer machines. Once the moisture content has lowered you can start the threshing operation, which can be done by various ways. Listed are some modalities of corn-sheller, manual type and mechanized.

Ways of corn-Sheller

Manual Corn-Sheller

  1. Scrubbing of a cob or corn husks against another cob.
  2. Scrubbing cob against a bundle of husks or cob.
  3. Seeded by a corn Sheller cone.

Mechanized Corn-Sheller

This is done by a machine powered by a tractor, which is what is used in our area.

Corn Storage

After being seeded the corn is moved to the Collection Center owned by the Association of producers for treatment. Corn is a grain that requires special care and moisture, for storage must be at 13% to their proper preservation.
