Uniformity of lettuce
Lactuca sativa L.
Uniformity of lettuce determines the degree of plant homogeneity based on morphological and physiological traits, which is critical for simultaneous harvesting.
In the reference 40 varieties crop Lettuce, where this is mentioned in the description.
For lettuce (Lactuca sativa L.), uniformity is characterized by the homogeneity of plants in terms of weight, rosette size, height, leaf count, head density, and stage of market maturity. Assessment is carried out visually or quantitatively, including the use of computer vision systems that analyze canopy projection area and plant compactness.
High uniformity at a level of 90–95% allows for single-pass harvesting, which increases marketability up to 98% and reduces labor costs. Heterogeneity in growth rates is an indicator of failures in irrigation, nutrition, or microclimate management, requiring adjustments to production conditions.
