Irrigation (1) is the supply of water to crop plants at regular intervals to meet their need for water which is not fulfilled by rainwater alone.

Harvesting of the crop is followed by its storage (2) at a proper dry place to ensure grain spoilage by moisture content and to prevent pathogenic infections (spoilage by rats, worms, etc).
