The present study assessed the nutrient depuration capacity of Polygonum hydropiperoides by cultivating plants hydroponically in water obtained from fish ponds. The experiment simulated varying degrees of nutrient enhancement by using pond water enriched with nitrogen (N) and phosphorus (P) at the following concentrations (in mg L-1): 0-0 (NcPc), controlgroup; 105-15 (N1P1); 155-30 (N2P2); 185-45 (N3P3), and205-60 (N4P4). The sources of N and P were urea and diammonium phosphate, respectively. Experiments were carrie doutusing acompletely randomized design, with six replicates and five levels of added N and P, and lasted for 40 d until plants reached maturity. Plant morphological and chemical variables were recorded, and depuration efficiency was measured based on the total shoot biomass and the nutrient content per treatment. The best performance was observed in the N1P1 treatment, achieving a water depuration rate of 74% for N and 81% for P. These results suggest promise for using emergent plants such as Polygonum grown in hydroponic culture to remove excess nutrients from aquaculture sites. |
