Variety traits
Allium cepa L.
A key indicator of onion cultivar productivity, measured by weight as the total or marketable mass of produce per unit area. It varies from 220 to 580 dt/ha depending on the cultivation method, plant density, and agronomic background.
In the reference 113 varieties crop Onion, where this is mentioned in the description.
Onion yield is subdivided into total and marketable, where the latter reflects the mass of quality bulbs meeting standardization requirements. Centners or tonnes per hectare are used to evaluate productivity, while kilograms per square meter are used in field trials.
Potential productivity directly depends on the cultivation technology, whether it is direct seeding, planting sets, or the transplant method. There is an inverse correlation between high yield and storage quality, which is particularly characteristic of southern cultivar types.
Key factors in crop formation are optimal plant density, which prevents the production of undersized bulbs, and a balanced mineral and organic nutrient regime, which determines both the mass and the chemical composition of the yield.
