This study observed the effect of medium size and organic compost dosage on the growth and yield of red lettuce (Lactuca sativa L. var red rapids) in pots. A 3x4 factorial treatment in a completely randomized design with 3 replicates tested medium sizes (1kg, 3kg, 5kg) and organic compost dosages (0%, 10%, 30%, 50%). Results showed that red rapid lettuce growth was depressed at 1kg and 3kg medium sizes but grew more freely at 5kg. The treatment combination of 3kg medium size-10% compost dose, yielding 75.3g per plant, was considered the most optimum due to using the least amount of medium and compost, despite restricted growth.

This study examined household-level participation in urban agriculture (community and home growing) before (2017) and during (2020 lockdown) the COVID-19 pandemic in Phoenix, AZ, and Detroit, MI, using two online surveys and bivariate probit models. It found that considerably fewer individuals participated in community gardens compared to home gardening, and overall participation was lower in 2020 than in 2017. The continuity of individuals' participation in growing food at community gardens and home is fragile, and many urban households' food-growing practices may not yet be mainstream, suggesting other barriers inhibit participation.
