In order for corn to last long at the time of storage, need a way to store good corn. Until now the quality of maize at the farm level does not meet the criteria of good corn quality. Because of the high water content and the number of broken grains. To measure the water content is already available solution, that is with the help of tool Moisture Meter.
In practice at harvest time, the corn is abundant so the price is cheap. While at the time of famine, the price becomes expensive. Therefore, storage is very necessary to overcome the excess production during the harvest season to be utilized in times of famine.
Several attempts to find a technique to keep corn for long lasting continue to do. For storage to note is the air content of 1-2% below the moisture content with a maximum moisture of 80%. Try to keep the material dry and cold and can protect against the attacks of haama.
Problems of corn farmers one of them is the storage process. They should pay attention to the storage process as it affects the quality of maize. So it will determine the selling price. Efforts to maintain corn quality during storage were with disulfide (CS2) cabins, storage with sacks, and storage with silo tower.
Using Carbon Disulfide (CS2)
The use of liquid carbon disulfide (CS2) can suppress the damage of corn pipes during storage. The technique of using CS2 is not difficult, because liquid CS2 is easily oxidized. So as to form CO2 and SO2 that is a toxin to insects, and inhibit microorganisms. The use of CS2 dose of 0.25 cc/kg of corn pipes can extend the shelf life of up to two years with less than 1% damage.
Storage with Sacks
The main factor that needs to get attention is the cleanliness and durability of the container type. The container should be clean and not leak, thus as long as in the container, the corn kernels are not susceptible to attack by pests and diseases. Therefore, use plastic bags sacked with the sack. After that tie tightly or sew along the hole strong and tidy.
The containers we use should be cleaned first. If necessary we spray with insecticide liquid Silosan 25 EC 2% and Damfin 50 EC dose 500 cc/10 lt to 500 m2.
Such conditions will facilitate the transportation. Especially for corn kernels, the rate of loss due to scattered greater than cobs corn.
Storage with Silo Tower
For consumption purposes, corn can be stored in cement bamboo silos. This silo is easy because we can get the building material easily in the countryside. The capacity of the silo is 1,000 kg (1 ton) with size 125 cm and height 100 cm. The silo can be used for 20 years.
The way of storage is corn we drain corn kernels until the water content reaches 12.5-13%, then we put in silos.
Another way is to make a silo pad of gravel and sand layers. Storage of corn with silo tower can last 4-8 months without any pest warehouse.
