(A) Heat map and hierarchical clustering based on the soil, plant analysis, yield and disease incidence of three independent locations (1, 2 and 3) treated with different algal amendments (Untreated control, algal extracts (Acanthophora spicifera, Spirulina platensis), dried algal biomasses (DABs) of Turbinaria ornate and a mixture of Caulerpa racemosa and Cystoseira myrica (1:1)) at the harvest stage (120 days). The patterns shown in the heat map indicate the average of three replicates for each parameter. Lower and higher concentrations were denoted by red colors and green respectively. The analyses were achieved by Pearson distance metric of the Multi Experiment Viewer (MeV)? 4 software package (version 4.5, Boston, MA, USA). (B) Correlation analysis of multiple factors for pooled data from the three different locations. SoilN, SoilP and SoilK = Nitrogen (ppm), Phosphorous (ppm) and Potassium (ppm) respectively. PlantN, PlantP and PlantK = N%, P% and K% respectively Phenols, Flavenoids and Antioxidants (ppm) Antioxidants = Total Antioxidant Capacity The analysis was carried out in R (4.3.0) with the “ggplot2” and “reshape2” packages
