Variety traits

Lettuce productivity

Lactuca sativa L.

A complex indicator of a lettuce cultivar's ability to form high-quality marketable mass, measured through biometric parameters of the rosette, head density, and yield per unit area.

In the reference 32 varieties crop Lettuce, where this is mentioned in the description.

Lettuce productivity is determined by a combination of biometric and economic traits: marketable plant weight in grams, marketable product yield as a percentage, and yield per square meter. Key elements of productivity include the height and diameter of the leaf rosette, leaf area, head density for relevant cultivar types, and the rate of biomass accumulation.

This indicator does not have universal values and depends directly on the cultivar type, cultivation conditions (open field, protected ground, or hydroponics), and the breeding background. In breeding, productivity is evaluated by comparison with control samples and in conjunction with the cultivar's stability against stress factors, such as temperature fluctuations or light deficiency.

In agronomic practice, productivity is closely linked to cultivation technology, including planting patterns and plant density. The efficiency of a cultivar is determined not only by total mass but also by the ability to avoid premature bolting and necrosis, which critically affects the final marketable yield.
