Examines intercropping strategies for weed control and crop yield in grain legumes, indicating potential benefits for organic farming.

The research aims to evaluate the effectiveness of buckwheat intercropping with grain legumes for weed management and yield preservation.
Conducted three randomized trials in northeastern Italy during 2023–2024.
Tested soybean, chickpea, and lentil intercropped with buckwheat at different ratios (2:1, 4:1).
Compared additive alternate and mixed row intercropping methods.
Measured crop and weed biomass as well as crop grain yield; calculated land equivalent and weed performance ratios.
Intercropping at a 4:1 ratio with buckwheat in mixed intercropping maintained legume yield across species.
MIX25 mixed intercropping provided effective weed suppression.
Combining agronomical and mechanical weeding methods fosters agroecological practices, enhancing agro-biodiversity.

Virili et al. (2026) studied this question.
