Question

How is crop protection management a pre-harvesting and a post harvesting affair? Illustrale with examples

Answer 1

Crop production management involves both pre-harvesting and post-harvesting management.
In pre-harvesting management the farmer removes weeds, applies pesticides to the crop.
In post-harvesting management, the stored crop may be damaged by abiotic (humidity, temperature) and biotic factors (microorganisms, rodents, birds). Therefore, the crop is stored in dry or cold storage in order to protect it from these factors.
