Recent research published in ‘Heliyon’ has shed light on the potential of cultivating Cichorium spinosum L., commonly known as stamnagathi, in vertical farming systems. This study, led by Orfeas Voutsinos-Frantzis from the Agricultural University of Athens, explores how different white light spectra and nutrient solutions can influence the growth and nutritional profile of this wild leafy vegetable.
Vertical farming has gained traction as a sustainable method to produce crops in urban settings, utilizing controlled environments to optimize growth conditions. The research focused on two main experiments to assess the impact of various white light products—specifically Neutral, Full, and SunLike™—and different nutrient solutions on stamnagathi’s growth. The light treatments were designed to simulate natural sunlight, with varying ratios of blue to red light that affect plant development.
Interestingly, the findings revealed that while the different light spectra did not significantly alter the overall agronomical parameters or leaf anatomy of stamnagathi, they did influence stomatal characteristics. Plants under the Neutral light treatment exhibited larger stomatal dimensions compared to those under Full and SunLike™ lights. This suggests that the choice of lighting can affect plant physiology, potentially influencing photosynthesis and growth rates.
In the second experiment, the research team evaluated the effects of nutrient solutions on stamnagathi. The control nutrient solution was compared to formulations with limited nitrogen and elevated iron levels. While the overall agronomical characteristics remained largely unchanged, the study highlighted a significant increase in leaf tissue phosphorus under elevated iron conditions. This resilience to varying nutrient levels indicates that stamnagathi could thrive in less-than-ideal nutrient environments, making it a strong candidate for vertical farming systems that may face nutrient management challenges.
From a commercial perspective, this research opens up exciting opportunities for the agriculture sector. As urban populations grow and the demand for fresh, locally-sourced produce increases, vertical farming presents a viable solution. Stamnagathi’s adaptability to different light and nutrient conditions means it could be cultivated year-round, regardless of external climate factors. Furthermore, the potential for biofortification through elevated iron conditions could enhance the nutritional value of this leafy green, appealing to health-conscious consumers and providing additional market opportunities.
Overall, the study underscores the importance of optimizing cultivation conditions in vertical farming. By integrating stamnagathi into these systems, farmers could diversify their crop offerings while contributing to sustainable agricultural practices. As research continues to evolve, the insights gained from studies like this will pave the way for innovative farming solutions that address both consumer needs and environmental challenges.
