In a groundbreaking study published in the journal ‘Horticulturae,’ researchers are shining a light on a novel approach to cultivating Achyranthes japonica Nakai, a medicinal plant revered for its joint health benefits. Led by Ye Lin Kim from the Department of GreenBio Science at Gyeongsang National University, this research dives into the effects of pre-harvest UV-B exposure on AJN microgreens grown in vertical farms.
Traditionally, growing AJN takes a staggering two years in open fields, but this innovative method could drastically cut that time while enhancing the plant’s nutritional profile. “By using controlled environmental conditions, we’ve managed to produce high-quality AJN microgreens that not only grow faster but also boast higher levels of beneficial compounds,” Kim explains. The study highlights how short bursts of UV-B light can ramp up the production of secondary metabolites, particularly 20-hydroxyecdysone (20E), a marker of the plant’s medicinal value.
What’s particularly exciting is the commercial potential this research unlocks for the energy sector. Vertical farming, which relies heavily on controlled lighting systems, is becoming increasingly popular as urban agriculture takes root. With the right UV-B treatment protocols, farmers can optimize their energy use, maximizing the yield of these high-value crops without the extensive land requirements associated with traditional farming. “Our findings suggest that intermittent UV-B exposure is not just effective for boosting 20E levels but could also lead to more efficient energy consumption in vertical farms,” Kim adds.
This approach could inspire a wave of innovation in how we think about sustainable agriculture. As cities strive for food security and healthier options, vertical farms equipped with energy-efficient lighting systems could become the go-to for producing nutrient-rich foods. The implications extend beyond just AJN; this research could pave the way for other medicinal plants, making them more accessible to consumers and potentially transforming the market landscape.
As vertical farms continue to rise in popularity, the study emphasizes the importance of integrating advanced cultivation techniques with energy-efficient practices. By optimizing UV-B exposure, farmers can not only enhance the health benefits of their crops but also improve the overall market value, making this an enticing prospect for investors and consumers alike.
