The use of LED light in cucumber can produce a substantial high yield. This is evident from the LED test that Philips Horticulture LED Solutions is carrying out at the Warsaw University of Life Sciences. The test is done with the Qlipr system from Pellikaan Gewasklemsystemen. "Qlipr provides light and labor gains."
Philips Horticulture LED Solutions set up a trial with cucumber at the Warsaw University of Life Sciences in September 2014. With this trial Philips wants to gain more insight into the effects of LED lighting on a cucumber crop.
The cucumbers are planted in October, after which harvesting can begin in early November. Last year the harvest continued until the beginning of June. "In the midi cucumbers under LEDs we achieved a production of 47.13 cucumbers per m2 in the first, in the second crop 43.89 per m2 and the third 58.87 per m2," says Philips plant specialist Andris Stuks.
"Under HID light, this was 38.61, 33.7 and 42.82 units per m2 respectively, and I am very satisfied with the LED results, especially with the results in the last erop."
Easy and faster
The cucumbers in the test box are grown on the high wire and led up and fastened with the Pellikaan Qlipr Clamping Clamp System.
Andris Stuks chose Qlipr because of the slight gains made with this, as no rope reels hang from the top of the greenhouse.
"With this you can quickly gain 10% light."
In addition, Andris Stuks wanted to limit crop damage as much as possible: when turning in, according to the place specialist, too many heads are damaged. The sustainability aspect also played a role; the clips and Pellikaan-hooks last for many years.
"The Qlipr system is easy to work with," says Janina Gajc-Wolska, head of the Horticulture, Biotechnology and Landscape Architecture facility at the university.
"Turning in is not easy for most students, working with Qlipr is much easier, and it's also faster, which means we save labor." We average three times every two weeks, each time after the third or fourth leaf. Twice a week through the crop, so here too there is a profit. All in all, Qlipr has a clear added value. "
