Organic Wheat and Forage Legume Living Mulch Performance Across Two Growing Seasons

Experimental data from a study assessing forage legume living mulches in organic wheat systems over the 2022/23 and 2023/24 growing seasons. The dataset, authored by Danilo Scordia and shared under CC-BY-4.0, compares grain yield, protein content, weed suppression, and nitrogen requirements for durum and bread wheat varieties under different fertilization levels.

Use Cases

• Modeling the relationship between kernel weight and growing degree days based on data from different fertilization rates.
• Comparing weed suppression effectiveness between Medicago polymorpha and other legume species based on reported dry biomass reductions.
• Analyzing the trade-offs between grain yield and protein content in wheat-living mulch systems versus sole crops.
• Estimating biological nitrogen fixation contributions from Trifolium subterraneum based on reported kg N ha⁻¹ yr⁻¹ values.

Strengths

• Data covers two complete growing seasons (2022/23 and 2023/24), allowing for temporal analysis.
• Includes specific quantitative results, such as grain yield changes ranging from -9% to +40% and weed dry biomass reductions from -58% to -94%.
• Compares two distinct wheat species (Triticum turgidum subsp. durum and Triticum aestivum) under three nitrogen fertilization levels.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The dataset is small (735.6 KB), indicating a limited experimental scope.
