The use of long-term types of onion, in particular welsh, can diversify and enrich the ration of feed the vitaminized and phytoncidal products, that is characterized an early ripeness, productivity and protracted period of consumption. In the young green leaves welsh-onion is rich in mineral salts, organic acids, vitamins and easily assimilable carbohydrates.

The aim of our study was to compare the productivity of onion varieties batun `Piero` and `Wales` in the early spring and summer term revegetation in open ground.

Plant varieties `Piero` year term revegetation had conditionally phase of technical maturity by 7-11 days earlier than plants of the investigated varieties of `Wales`. On average, two years growing season onion varieties welsh onion `Piero` in the embodiment of the spring landing was 34 days, varieties of `Wales` ‑ 37 days, and in the summer term of planting ‑ respectively 39 and 47 days. Implementation of early spring and summer planting dates welsh onion for annual growth cycle provides conveyor delivery harvest from the second decade of April to the second decade of May and the third decade of August until the third decade of September. The level of productivity significantly affected by the magnitude of aboveground mass formed in phase shareware ‑ technical maturity in the first cut-off green and during digging annual bushes. Average summer planting varieties of `Wales` for the first gathering of the pen provided by 0,4 t/ha yield lower than sort `Piero`.
