Effects of (dynamic) LED lighting on growth and quality of vegetable crops

Since 2000, Anja Dieleman works as a (senior) scientist at the business unit Greenhouse Horticulture of Wageningen University & Research. With greenhouse crop physiology as her main application field, her research interests are the effects of greenhouse climate factors (light, CO2, temperature) and cropping systems on crop growth and development, including underlying processes like photosynthesis and transpiration. Recently, she has been working on the design of energy efficient LED based production systems, plant monitoring systems and effects of spectral composition of the light on plant growth, development and morphology. Since 2020, she is also working on the development of autonomous greenhouse cultivation systems. This research is done in close collaboration with greenhouse growers, (international) horticultural supply companies and national government.

Ir. Eric Poot has been manager of Delphy Improvement Centre in Bleiswijk since April 2024, where he leads applied research in greenhouse horticulture. With his team he focuses on the development and application of knowledge and technological innovations within cultivation systems, with the aim of making the sector more sustainable and future-proof. The Improvement Centre is also a leader in testing and demonstrating new varieties and technologies for high-tech greenhouse cultivation. Before his position at Delphy, Poot worked for years at Wageningen University & Research (WUR). Poot is an advocate of knowledge sharing and cooperation between research, business and education. He emphasizes the importance of integral approaches, in which factors such as light, climate and energy consumption are jointly optimized, and in which digitalization plays an essential enabling role. His vision is that horticulture makes an essential contribution to a healthy diet and the well-being of people worldwide, and that knowledge and technology play key roles in achieving sustainable food production.

Jesse Verbeke plays a key role at Phormium Climate Screens, where he supports customers in selecting and using climate screens in the most optimal way. He has extensive knowledge about screen properties and is actively involved in the development of new screen types, helping to innovate and refine solutions that meet the evolving needs of the horticultural industry.
