Primed seeds, once sown in the field, have an advantage over non-primed seeds because they have a lower water requirement before germination. Pelleting is a process in which seeds are coated uniformly to facilitate mechanical sowing. Tiny seeds such as lettuce can be difficult to seed evenly without pelleting. Some seeds are coated with fungicides or insecticides to protect the seed until germination. Enhanced seeds are especially important when growers are attempting to germinate a crop under less than ideal conditions.
Vegetable seeds are sown for immediate germination in the season appropriate for the crop.
Breeders select seeds based on a lack of dormancy requirements to ensure rapid germination. Fungicides, insecticides, and other coatings are often applied to seeds. Some seeds are disinfected through hot water or chemical treatments to kill weeds and pathogens. Choices should reflect the type of vegetable business they are running and the market outlet.
