Passionate, reliable and customer-oriented
Collaborating as a company
Building on 60 years of experience, PSKW is a trusted partner for industry. On our 10 ha of trial fields and in our 1.7 ha greenhouse infrastructure, we yearly perform numerous commissioned field trials for suppliers of horticultural products e.g. plant protection products, seeds, fertilizers and Agtech. We provide tailor-made and end-user-oriented trial designs with a great deal of expertise. Thanks to our core activities in public research, we master or develop state-of-the-art methodologies and technology. We have a close connection with growers and stakeholders (> 500 members) which enables us to help companies develop practical relevant products and user guidelines.
PSKW is specialized in the most common grown vegetables in the Benelux. The vegetables we grow in soil, be it in open field, polytunnel or greenhouse are mainly but not exclusively Brassicaceae (cauliflower, broccoli, cabbages, Brussels sprouts, turnip etc.), Alliaceae (leek, onion, garlic etc.), Apiaceae (celery, carrot, fennel etc.), Cucurbitaceae (zucchini, pumpkin, melon), asparagus and leafy vegetables (lettuce, spinach, lamb’s lettuce etc.). Vegetables we grow hydroponically in greenhouses are mainly lettuce (mobile gutter system), tomato, bell pepper, cucumber, eggplant and, zucchini.
What are the possibilities?
Crop protection
We combine experience, strategies, tools, and products that protect against various pests, from controlling the situation by reducing risk to dealing with the consequences of the problem. Your crops are in good hands at our Research Station.
GEP Efficacy and phytotoxicity trials
Since 2004 our trial station is certified to conduct GEP trials. The primary aim of
these trials is to ensure that high-quality trials are conducted.
Biological control and selectivity trials
PSKW has a great deal of expertise in research and development of biological control organisms, both microbials as macrobials.
Demonstration trials/events
The company and its clients can visit all these trials. We love to demonstrate our expertise and bring your practice to life.
Screening trials, residue studies and resistance monitoring
Products that are still in the research or early development phase may demand a specific trial design. Discover what we have to offer.
Rainfastness, UV-degradation and physical compatibility
Testing the possibilities of all of the above is part of our trials. In dialogue, we can come to a trial to make sure we meet your specific needs.
Seeds, biostimulants and fertilizers
The Research Station for Vegetable Production is well-known for its variety of trials. But we have a lot more to offer. Our infrastructure and people are fully equipped to conduct trials tailored to your needs.
Variety trials
Variety testing has always been an important pillar of our activities, both for indoor as outdoor vegetables. This is how we work.
Disease/pest susceptibility trials
For a range of disease and pests we offer susceptibility trials in which we test your resistant or tolerant varieties against diseases and/or pests in comparison to the reference varieties of your choosing.
Biostimulant trials
Biostimulants gain importance in vegetable cropping, their claimed effects on plant growth and/or abiotic stress tolerance can be proven or demonstrated in field trials.
Fertilizer trials
We offer trials to test if your fertilizer delivers a sufficient amount of nutrients for good crop growth and if your fertilizer delivers vegetables of good quality.
Co-development of automation solutions and innovative technologies
With our vast experience in (co-)developing various farming equipment and technologies, we can provide invaluable insights to help your company stay ahead of the competition. Collaborating with us can be more than just gaining access to our expertise and resources. It’s an opportunity to work together to develop new and innovative technologies that can benefit both your company and the horticultural industry as a whole.
Testing of machines and growing systems
Test runs of different crops on novel growing systems. Read all about it.
Robotics and remote sensing trials and demonstration
From early development and testing to demonstration and validating market-ready technologies.
Software and model validation
Climate control, sensoring – models for plant growth/yield estimation and/or pest and disease phenology
Artificial lighting trials
New light spectra, new lighting regimes, new types of lamps can all be researched at our facilities in cultivation of both fruiting and leafy vegetables
