Urban Farm DB summary
A two-year pot experiment was conducted from 2020 to 2022 on the roof of a four-story building to identify an optimal growing medium for dragon fruit cultivation on rooftops. Seven different combinations of soil, cocodust, biochar, and vermicompost were evaluated, with the medium comprising 80% cocodust and 20% vermicompost (T2) showing the highest branch count, fruit count, fruit weight, and yield in the second year. T2 also improved edible portion, TSS, and vitamin C contents, and exhibited the highest benefit-cost ratio (4.17).
