Abstract Soil compaction represents an important issue in the actual context of agricultural system sustainability. Research on the various developments of root systems under tillage has been explored for many crops, whether for the biomass area or the underground, but very little concerns Sunflower (Helianthus annuus L.). The objectives of the study were to understand the impact of soil tillage and of the induced mechanically compacted soil on: i) sunflower’s root system architecture, ii) biomass area iii) production. Two complementary experiments were realized in the south of France (France’s main sunflower production area). In both experiments, increased resistance of the soil… More >
