Redroot Pigweed Interference Effects on Four Lettuce Cultivars

Eloisa Casadei's study evaluates the effect of redroot pigweed density and distribution on lettuce crop yield. The experiment measured yield losses of up to 45% for the cultivar Lídia, with other cultivars showing losses between 28% and 41%. The research was conducted in an open and semi-controlled area using a completely randomized experimental design with three replicates.

Use Cases

• Modeling crop yield loss based on weed density and positioning mentioned in the description
• Comparing cultivar tolerance to weed interference based on the four lettuce varieties tested
• Analyzing the impact of allelopathic compounds on crop growth as suggested by the study background

Strengths

• Provides specific yield loss percentages for four lettuce cultivars (up to 45% for Lídia)
• Describes a controlled experimental design with three replicates and specific weed densities (4 and 16 plants m⁻²)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Last update date is unknown; freshness unverified
