Other claims from this paper (6)
- Association A high-weed area of about 9 ha had mean yield 78% below the most productive cluster.
- Association Spike number per square metre was low where weeds were abundant.
- Observation A 7.3 ha area had harvest yield 45% above the field mean.
- Method / resource Clustered Sentinel-2 NDVI maps from tillering to booting represented the effect of weed distribution on crop yield and components.
- Recommendation The authors propose Sentinel-2 clustering as an early warning tool for weed limitation in organic farming.
- Recommendation The authors suggest precision agriculture tools can support site-specific organic farm management.
