Variety traits

Vegetation period — head lettuce

Lactuca sativa L. var. capitata L.

This is the time interval from mass emergence to the stage of marketable maturity, measured in days. The duration of this period determines the earliness of the variety and serves as the basis for planning continuous production.

In the reference 10 varieties crop Head lettuce, where this is mentioned in the description.

The vegetation period of head lettuce covers the stages of development from emergence to the formation of a head of the required diameter and density. Depending on varietal characteristics and growing conditions, early-maturing varieties reach maturity in 40–45 days, mid-season varieties in 50–60 days, and late-maturing varieties in 70 days or more.

Precise tracking of this indicator is critical for planning continuous harvesting and choosing cultivation technology. In protected ground conditions, the vegetation period can be reduced by 10–15 days. It is important to consider the risk of premature bolting caused by high temperatures and long daylight hours, as well as the short harvest window, which lasts approximately 10–12 days.
