Identify the abiotic factor which results in storage loss.?

Option 3 : Moisture

The correct answer is option 3, i.e. Moisture.

Storage of Grains - 

• In agricultural products, storage losses are very high.
• Factors responsible for such losses are biotic and abiotic.
  • Biotic - insects, rodents, fungi, mites and bacteria, and
  • Abiotic - inappropriate moisture and temperatures in the storage place.
• These factors cause a loss in weight, discolouration of produce, poor germinability, degradation in quality, all leading to poor marketability.
• But these can be controlled by systematic management of warehouses and proper treatment.
