Efficiency of using organic fertilizer from seafood sludge as substrate and hydroponic solution on leafy vegetable yield
Main Article Content
Abstract
The 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.
