📦 Seed Storage

Seed storage management aims to slow deterioration so that seed maintains viable germination and field performance until the intended sowing period.

Seed Deterioration Concept

Seed deterioration is a progressive and irreversible process. Germination loss is the last visible stage; vigor decline begins much earlier.

Practical meaning:

• Seed can germinate but still perform poorly in field.
• Storage decisions must target vigor, not only final germination percent.

Moisture and Temperature Effects

Moisture and temperature are the two strongest drivers of storage life. High values accelerate biochemical damage and pathogen activity.

Control strategy:

• Dry seed to safe moisture before storage.
• Keep storage environment cool and dry.
• Avoid repeated moisture fluctuations.

Storage Structures and Containers

Container choice depends on expected storage period and local humidity.

Common options:

• Moisture-vapor-pervious containers for shorter storage.
• Moisture-vapor-proof containers for longer storage.
• Clean pallets and stack spacing for ventilation and hygiene.

Monitoring and Lot Management

Lot-wise monitoring prevents unnoticed quality decline.

Monitoring essentials:

• Periodic germination and moisture testing.
• FIFO or planned dispatch strategy.
• Removal of damaged or infested lots.
