Soilless cultivation allows high water and nutrient use efficiencies when drainage water is recycled. However, a full closed-loop irrigation system is not easily achieved. Among other issues, the drainage water quality can be worsened when recirculated due to sodium (Na) accumulation, occurring when the Na input concentration is higher than the act...

For a first step integrating elicitor applications into the current IPM strategy increasing plant resilience against pests, we investigated repeated elicitor treatments in a strawberry everbearer nursery and cropping cycle under glass. During nursery methyl-jasmonate (MeJA), testing induction of defenses with plant bioassays was applied every 3 wee...

Over a period of seven years (2009-2016) hydroponic chyrsanthemum cultivation has been developed andtested in practice. Where the system delivered up to 25% higher yields at smaller scale, the larger systems of250-300 m2 turned out very sensitive to root infection. Research then focussed to understanding the key factorsthat caused the plants to bec...
(Semi-)closed greenhouses have been developed over the last decades to conserve energy. In a closed greenhouse, window ventilation is fully replaced by mechanical cooling while solar heat is temporarily stored in an aquifer. A semi-closed greenhouse has a smaller cooling capacity than a closed greenhouse and, in which mechanical cooling is combined...
Wageningen University & Research, BU Glastuinbouw heeft in opdracht van Kas als Energiebron een integraalenergiezuinig teeltconcept voor Alstroemeria ontworpen en doorgerekend. Elementen in het teeltconcept zijn:maximaal isoleren (twee schermen), zorgvuldig ontvochtigen met een Ventilation Jet, isoleren van de bodem,energiezuinige bodemkoeling en “...
Met financiering door “Kas als Energiebron” (Ministerie van Economische Zaken en LTO Glaskracht) en de Kennis Coöperatie Gerbera is in 2015-2016 het onderzoek “Gerbera: Teelt in Balans” uitgevoerd met als doel het energie en CO2 verbruik in de gerberateelt verder te verlagen. De rassen Pre-Semmy, Rich, Whisper en Suri zijn hiertoe in drie kasafdeli...
