Ngày duyệt đăng: 07/02/2020The aim of this study was to use organic fertilizer from seafood sludge as substrate and as hydroponic solution. The first experiment was carried out with 4 treatments in net house condition including: (1) control (only soil), (2) Soil+ recommended chemical fertilizer, (3) Soil + 5 tons/ha seafood sludge compost (SSC), and (4) Soil + 5 tons/ha sugarcane cake compost (SCC). The second experiment was conducted with 4 treatments consisting of (1) water (control), (2) extracted solution at ratio of 1:5, (3) extracted solution at ratio of 1:10, and (4) commercial hydroponic solution. Results showed that the yield of green mustard was found in the treatment amended with 5 tons/ha of SS compost five times higher than control treatment. The yield of salad vegetable on hydroponic solution at diluted ratio of 1:10 increased more than 65% compared to the control treatment.
