Maximizing Strawberry Quality and Yield with LED Grow Light Technology

In the quest for improving the quality and yield of strawberry crops, in Research study titled “Effects of LED light on the production of strawberry during cultivation in a plastic greenhouse and in a growth chamber” the researchers thoroughly investigated the impact of LED Grow light technology on strawberry cultivation. This research aimed to unravel the intricate relationship between different LED grow light wavelengths and their effects on the vegetative growth, fruit yield, and phytochemical composition of strawberries.

Strawberry Cultivation

The study focuses on optimizing environmental factors, with an emphasis on grow light, to enhance fruit quality. Previous efforts using traditional light sources such as incandescent and fluorescent lamps have now given way to the promising technology of Light Emitting Diodes (LEDs) Grow light technology.

LED grow light Technology: A New Frontier in Agriculture

The adoption of LED grow light technology in agriculture has gained momentum in recent years. Unlike traditional light sources, LED grow lights allow precise control over light spectrum, with red and blue wavelengths being particularly effective in promoting photosynthesis. The study conducted a comparative analysis between a growth chamber (GC) utilizing LED grow lights as the sole light source and a plastic greenhouse (PG) incorporating both ambient and supplemental LED grow light.

Results: Unveiling the Impact of LED Wavelengths

1. Vegetative Growth and Fruit Yield:

Blue LED light proved effective in promoting leaflet length and petiole development.
Plastic greenhouse exhibited superior vegetative growth, suggesting the importance of PPFD in conjunction with LED grow lights.
Fruit yield was significantly higher in the PG, especially under combined blue and red LED light.

2. Soluble Sugars and Organic Acids:

Sucrose content increased in GC fruits, while PG fruits exhibited higher organic acid levels.
LED wavelengths influenced sugar accumulation, with blue LED light being less efficient in sucrose formation.
Red LED light was most effective in organic acid production in the PG.

3. Phytochemicals and Antioxidant Activities:

Red LED light emerged as the most effective in phenolic compound accumulation.
Blue and red LED light combination excelled in anthocyanin production.
PG consistently outperformed GC in phytochemical production and antioxidant activities.

Discussion: Deciphering the Impact of LED Light on Strawberry Growth

The study's findings present a nuanced understanding of how different LED grow light wavelengths influence various aspects of strawberry cultivation. Contrary to some existing beliefs, the growth chamber did not outperform the plastic greenhouse, emphasizing the importance of PPFD in tandem with LED grow lights. The increased yield in the Plastic Greenhouse can be attributed to a higher PPFD level favouring photosynthetic efficiency.
