Mastering The Importance of Photoperiod in CEA Strawberry Production
Strawberry is now the crop on the spot of current research when speaking about LED lighting for crop production. Greenhouse production and the interest in indoor production for strawberries are expanding every day. Therefore now researchers are looking to learn more about the best light quantity and quality.
Light quantity in strawberry
Speaking about light intensity most updated research has shown light intensity around 200 to 250 μmol m-2 s-1 can have good results food indoor and supplemental lighting on strawberries. This crop seems to be more sensitive to high light intensity than other common crops.
In greenhouse applications we know recommended DLI levels can go from 17 to 20 mol m-2 d-1. However light intensity used in research done in indoor facilities can point to maintaining low DLI levels in order to have better overall results and better benefits from the light quality provided.
Light quality in strawberry
Research done by the research foundation Proefcentrum Hoogstraten in Belgium demonstrated the importance of Far-red light for strawberries.
This research suggests that the addition of 5% of Far- Red light to the light spectrum can be a real advantage for strawberry plant development. A fuller, more elongated crop is created. In this research, the best light quality for strawberry was reported using 7% Blue, 16% Green, 72% Red, and 5% Far-Red. More recent research has also concluded far-red can have a good impact on yield, plant morphology, and fruit quality.
