Commercial onion seed procurement
For commercial onion plantings, SeedMatchGroup turns your planting plan into a lot specification (day-length type, variety or traits, quantity, test data, documents and delivery window) and collects reviewed offers from qualified suppliers. We do not hold seed inventory or promise particular varieties; offers state what each supplier can document for your destination.
What to specify
- Day-length type (short, intermediate or long day) matched to your latitude and sowing date; ask your agronomist or extension service to confirm.
- Hybrid or open-pollinated, bulb colour, storage and market traits, and any disease tolerances you need.
- Planted area and target plant population, so the seed quantity is calculated rather than guessed.
- Minimum germination and purity, test date, and seed treatment (or untreated) as required by your import permit.
Calculating the lot size
Seed quantity = planted area × target plants per area ÷ (seeds per kg × germination × expected field emergence). Use your own population and emergence assumptions, and the seeds-per-kg and germination figures the supplier reports for the actual lot. The seed rate calculator applies the same formula.
Documents offers should include
- Germination and purity test report for the specific lot, with laboratory and test date.
- Phytosanitary certificate issued by the exporting country's plant protection organization, with any additional declarations your permit requires.
- Variety name, lot number, packing size and treatment declaration.
- Shipping terms, transit time and storage conditions in line with your sowing window.
Request terms
SeedMatchGroup reviews project requests from USD 250,000 in total value. Buyers use the service free of charge; qualified suppliers pay. Supplier identities stay confidential until a reviewed introduction.
