Evaluation of Vegetable Production on Extensive Green Roofs

Urban Farm DB summary

This study evaluated vegetable and herb production across three growing systems—a green roof, raised green roof platforms, and in-ground—over three seasons (2009–2011). Tomatoes, green beans, cucumbers, peppers, basil, and chives were cultivated. All plants except pepper survived and produced biomass in all systems, yielding crops for analysis in 2009 and 2010. Yields and basil biomass were higher in-ground in 2009, while roof and platform systems showed similar results. The study suggests that vegetable and herb production is possible and productive in extensive green roof systems with proper management.
