Aquaculture effluent can supply certain plant nutrients in adequate amounts. However, the nutrients present in
the fish waste solution are not balanced. Mixing this effluent in an independent unit with a hydroponic nutrient
solution can help to optimize conditions for the plants and minimize such drawbacks. The objective of this work
was to assess the crop production and the nutritional responses of Pelargonium zonale fertigated with different
percentages of fish wastewater. Five treatments were performed: 100NS, 75NS+25AS, 50NS+50AS,
25NS+75AS and 100AS, where AS is the fish wastewater and NS a hydroponic nutrient solution. The species
used to provide the fish waste solution was tilapia nilotica (Oreochromis niloticus). The results of this assay show
that: i) fish wastewater can be utilized for the fertigation of Pelargonium zonale (a short-cycle crop) as there are
no differences in the leaf, stem-petiole and flower dry matter, leaf water content, leaf area, plant height and l...
