Question

4. Why storage of grains leads to losses? What preventive and control measures are adopted before grains are
stored for future use?​

Answer 1

Due to biotic factors like insects, rodents, fungi, mites, bacteria and abiotic factors like inappropriate moisture and temperature in the place of storage, there is degradation in quality, loss in weight, poor germinability, discolouration of produce, all leading to poor marketability.So, preventive and control measures are used before grains are stored for future use, which include strict cleansing of the produce before storage, proper drying of the produce first in sunlight and then in shade and fumigations by using chemicals that kill pests.

Grains must be dried thoroughly otherwise there are chances of rottening.

Grains need to be stored in room free of moisture.

Tin-boxes should be preferred as they are mice-proof.

In godowns, chemical used to prevent rats and insects must be used carefully in such as way that grains are not contaminated.

Old gunny bags should be sun-dried.

Storage places should be well-ventilated.

During transportation of grains, gunny bags must be covered properly so that no wastage takes place..
