Seed Deterioration
Seed is a living matter and if not handled and stored properly it deteriorates and gets damaged.
Main reasons for deterioration are:
– high temperature in storage area
– high humidity in storage area
– high moisture content of seed
– improper packing
– seed is not cleaned or treated
– presence of pests and diseases
– natural short-lived seed variety
– incorrect chemicals used for treatment
Proper Handling and Storage of Seed
When receiving seed bags, it must be ensured that these are properly labeled and different seeds stacked separately
• Bags should not be dropped or thrown around – seed may split
• Heavy items should not be placed on seed bags during transportation or storage
• Seed bags should be stored on palettes or dunnage in dry, well ventilated stores
• First in, first out (FIFO) inventory system should be maintained
. Weevils, rodents and other pests must be controlled
• Efforts should be made to avoid extreme temperatures during storage
• Recommended moisture content of seeds (~12%) should be maintained; over 14% mold growth may occur and below 5% seed is damaged due to desiccation
• High humidity in store must be avoided
• Chemicals that emit vapors may damage seed and should be stored separately
• Seed should not be sold from open bags
