At the end of each season, the Swiss greenhouse vegetable sector meets to identify problems threatening producer competitiveness. Representatives include cantonal agricultural offices, CCM/SZG, UMS/SZGP, SWISSCOFEL, research institutions (Agroscope, HEPIA, HEIG-VD, ZHAW, HAFL), Inforama, and others. This approach allows dynamic updating of sector challenges and enables research to respond rapidly. The platform legunet.ch lists all actors and applied research projects. Swiss greenhouse producers need practical, multidisciplinary research with short-term applicability. Collaborations involve specialists in cultivation, energy, nutrition, phytopathology, entomology, and more. Research covers soil-based and soilless systems, conventional (SGA) and organic (BIO) production. The project has four specific objectives: SO1 – promote knowledge transfer; SO2 – address cultivation techniques; SO3 – address fertigation; SO4 – tackle diseases, viruses, and pests. Case studies are updated annually or biennially.
