Question

why should the grains be sun dried before storing?​

Answer 1

Grains should be sun dried to remove the water from it, so that it can prevent the growth of microorganisms.

Answer 2

Ello❤️

If freshly harvested grains are stored without drying they may spoil or get attacked by microorganisms, losing their germination capacity. Hence, before storing them the grains are properly dried in the sun to reduce moisture in them. This prevents the attack by insects, pests, bacteria, and fungi.
