Organisation d'une placette de relevés avec les mesures de densité et de diversité d'insectes pollinisateurs et les cinq capitules avec les trois traitements (pollinisation tulle PEI, pollinisation libre PL et pollinisation saturante PS) randomisés au sein de chaque rang. Les cinq capitules orange indiquent la localisation des capitules utilisés pour mesurer la production nectarifère (placette centrale de la parcelle uniquement).
