Seed damage
This refers to mechanical injuries to the seed coat or embryo caused during harvesting, processing, handling, or planting operations.

Seed damage is a significant concern in agriculture as it directly impacts the germination rate and seedling vigor. Mechanical stresses, such as high-impact forces in threshers or excessive drop heights in handling equipment, create openings that allow soil-borne pathogens to attack the embryo.
The economic consequence is poor crop establishment and increased susceptibility to diseases. Even invisible micro-cracks can significantly reduce the storage life and field emergence potential of the seeds, leading to uneven crop stands.
Common mistakes: harvesting grain at very low moisture levels, incorrect settings of threshing cylinders, and using improperly adjusted conveyors. Proper equipment calibration and careful handling are essential to maintain the structural integrity of the seeds.
