How do storage grains loses occurs

Posted by Aman Shukla 7 years, 4 months ago

CBSE > Class 09 > Science

1 answers

Yogita Ingle 7 years, 4 months ago

During the storage of grains both biotic and abiotic factors cause losses to the grain. Biotic factors such as insects, rodents, mites, fungi, bacteria, etc. and various abiotic factors such as moisture, temperature, lack of sunlight, etc. are responsible for losses of grains. These factors cause loss in weight, degradation in quality and poor germinability.
