Abstract :Due to the frequent ice-ice disease outbreak and stagnant growth of Kappaphycus species, farmers and researchers have been considering nutrient enrichment as one way of easing these issues to increase production to meet the growing demand for carrageenan in the world market. In this study, we determined the effects of organic and inorganic fertilizers as nutrient enrichment on the ice-ice disease occurrence and growth performance of seaweed Kappaphycus striatus. Three treatments were used in the study: T1 = Acadian Marine Plant Extract Powder insert ignore into journalissuearticles values(AMPEP); at 0.01 g L-1, T2= ammonium phosphate, 16-20-0 at 8.82 g L-1, and T3 = control. Nutrient-enriched seaweed K. striatus was planted using the fixed-off bottom method for 45 days. Findings revealed that the growth performance of T2 insert ignore into journalissuearticles values(6.1±0.14 % day-1); was significantly higher insert ignore into journalissuearticles values(p<0.05); after 30 days compared to T1 insert ignore into journalissuearticles values(5.56±0.16 % day-1); and control insert ignore into journalissuearticles values(5.45±0.17 % day-1);. In terms of ice-ice occurrence, T1 insert ignore into journalissuearticles values(0.57±0 %); was significantly lower after 45 days of culture compared to control insert ignore into journalissuearticles values(59.67±27.32 %); but not significant with T2 insert ignore into journalissuearticles values(23.22±12.83 %);. Our study suggests that organic fertilizer insert ignore into journalissuearticles values(AMPEP); could effectively reduce the ice-ice disease occurrence, while ammonium phosphate could enhance the growth performance of K. striatus.
