Indicators of sunflower performance (grain yield, treatment frequency index (TFI), semi-gross margin (GM), oil concentration) for different cropping systems (AE, BI, TBI, Reference) on the long-term experiment of Toulouse-Auzeville (INRA). CIMS (multi-services cover crops). Numbers in italics indicate standard deviation (SD, 3 years).
