Seed Grading is the term used for getting the largest, healthiest seed suitable for sowing the next seasons crop. Plants from larger seeds are often more vigorous, grow more quickly and produce more tillers, especially at the early stages of growth. The difference between plants from small and large seeds may be greater under competition from weeds. In the plant world, most resources are available on a first-come-first-served basis. The advantage generally goes to the first plant to occupy the space, creating shade, using the water and nutrients. Larger seed is proven to increase yield and also shows that seed can be harvested earlier too!
Seed dressing refers to the application of natural trace elements and protective coatings, to guard against fungal infections, diseases & infestations by pests.
