Our results showed that both the sloped (SD) drip culture platform design, and the multi-level horizontal design (MLHD) produced significantly higher rates of NO 3 uptake when compared to the totally submerged controls (SUB). Additionally, the bag-pouch vertical drip culture Table 2. Biomass **data** passed normality (Shapiro-Wilk; P = 0.087) after log transformation and equal variance tests (Brown-Forsythe; p = 0.682). Two-way Analysis of variance of the JSM fertilizer concentrations (1X, 2X, 4 X and 8X) and cultivation design (MLHD, BPVD, SD, SUB) on the daily growth rate of U. compressa. Ã The mean difference is significant at the 0.05 level. Land-based drip-irrigated culture of Ulva compressa Table 3.
