Question 5

How do storage grain losses occur?

Answer

Both biotic and abiotic factors play an important role in the spoilage of the stored seeds. Biotic factors such as insects or pests that cause direct damage by feeding on seed. Abiotic factors such as temperature, light, moisture, etc., also affect the seed. They decrease the germinating ability of the seeds and make them unfit for future use by farmers. Unpredictable occurrence of natural calamities such as droughts and floods also causes destruction of crops.
