Variety traits

Yield — Onion

Allium cepa L. var. cepa

The yield of onions is measured gravimetrically in t/ha and is divided into total and marketable yield, determined by bulb diameter. The indicators depend on the cultivation method, plant density, intensity of agrotechniques, and the genetic potential of the cultivar type.

In the reference 140 varieties crop Onion, where this is mentioned in the description.

Yield assessment during onion variety testing is conducted on a per-plot basis, separating total and marketable mass, with the latter including bulbs meeting the established standard, typically with a diameter of more than 4 cm. The average yield in Russia using traditional technologies is 20–30 t/ha, whereas the use of intensive methods and drip irrigation allows for yields of 50–60 t/ha and higher.

The final productivity of the crop depends on the cultivation method, with the transplanting method often contributing to increased marketable quality. There is a correlation between a variety's yield potential and its storability, which requires a balance when selecting breeding material. Important factors in realizing this potential also include plant stand density, nutrient management, and protection against pathogens such as downy mildew.
