Integrating urban agriculture with aquaculture can reduce the use and cost of water, competition for chemical fertilizers, environmental impact discharging nutrient-rich agricultural water into fresh saltwater bodies. In addition, in cities directly benefit human health by providing a local source lean protein. Despite potential advantages, few studies have demonstrated feasibility production advantages using wastewater to fertigate specialty crops an environment. Therefore, we grew four...
Urban populations may struggle to access health-promoting fresh fruits and vegetables, urban agriculture approaches are of increasing interest. In this study, we used five cropping systems for environments produce strawberry fruit, a popular high-value fruit. Two green roof systems, hydroponic system, an aquaponic raised bed system were grow six cultivars: 'Albion,' 'Eversweet,' 'Monterey,' 'Portola,' 'San Andreas' 'Seascape.' We measured total mass marketable mass, size, percentage rotted...
Urban agriculture is expanding but faces economic and environmental challenges. One way to mitigate the impact of climate change on food security in cities with a temperate grow crops adapted hotter temperatures expected by middle twenty-first century. Hibiscus sabdariffa L., commonly called red sorrel or roselle, hardy shrub widely grown throughout tropical regions world that has high value as crop. Most studies H. have been conducted areas and, our knowledge, none compared genotypes, their...
Agriculture in urban and urbanizing areas will be increasingly critical to enhancing food security sovereignty, creating income, strengthening social interactions, improving health outcomes cities. We used three roofs, a hydroponic system, an aquaponic field rows environment grow six dwarf tomato cultivars: ‘Micro Tom’, ‘Red Robin’, ‘Sweet ‘n’ Neat’, ‘Terenzo’, ‘Tiny Tim’, ‘Tumbler.’ measured the marketable yield non-marketable yield, mass of tomatoes exhibiting defects, content 12 mineral...
The phytochemical composition in the leaves of seven accessions Hibiscus sabdariffa L. grown under field, green roof, and high tunnel conditions was investigated present study. Principle component analysis freeze-dried using near-infrared (NIR) spectral fingerprinting revealed differences between three growing conditions. Under all conditions, NIR fingerprint data accession PI 286316 showed variation from other six (PI 256041, 267778, 273388, 275414, Thai red, UDC green). A detailed...
Spindly Leg Syndrome (SLS) is a persistent animal welfare issue associated with the rearing of amphibians in captivity. We conducted two experiments to investigate effects diet, water composition and overfeeding on prevalence SLS newly metamorphosed harlequin frogs (Atelopus spp.). In our first experiment, we offered 400 full-sibling tadpoles Atelopus certus isocaloric diets treatments 31%, 37%, 42% 48% crude protein respectively. Tadpoles fed higher faster, but incidence exceeded 80% all...
Kale, Brassica oleracea L. var. acephala, is an important urban crop for human health and may potentially be grown year-round even in a temperate climate. We investigated black plastic straw mulch compared to bare soil cover low tunnels at 10 garden sites within high tunnel the USA ascertain influence on yield nutrients of Red Russian kale, temperature, air weed pressure, aphid abundance. Kale had sites, likely because outside environment was too cold gain retain heat. Cultivating kale...
Abstract Making woody mulch (WM) from organic waste is one solution for repurposing waste. Our work had two primary objectives. First, we wanted to destermine the current use of WM as a soil cover, barriers use, benefits, and possible motivations adopting by home commercial growers cultivating crops in Barbados Baltimore-Washington, DC metropolitan region USA. To accomplish this objective, administered survey both regions. Second, determine benefits using agricultural production sweet...
Sweet potato greens are an underused but highly nutritious vegetable that grows well in urban environments and could help alleviate food insecurity related health problems. Therefore, trials were conducted field rows a green roof with seven varieties of sweet potatoes to determine whether 1) they differed their production 2) harvesting influenced yield or nutrients storage roots. There was no difference the mass harvested among either system. Harvesting severely reduced roots, although it...
