- Abstract
The growth in demand for fish farming products has resulted in an increase in the generation of organic waste from fish processing. Such waste contains a high amount of organic matter which, when handled incorrectly, leads to environmental contamination. On the other hand, they have a high potential for agricultural use in the substrate composition for plant cultivation. Based on this, the objective was to analyze the use of organic residues from obtaining mechanically separated meat (CMS) of tilapia in the composition of substrates for the cultivation of sunflower plants. The experiment was conducted with a completely randomized design, located in a greenhouse, an isolated environment with a structure covered in nylon, located in the municipality of Maracanaú, Ceará, Brazil (3º52'19.8” S and 38º36'41.6” W), during the month June 2022. On the 21st and 27th days after sowing, growth assessments were carried out by measuring height, stem diameter, number of leaves and relative chlorophyll content. Additionally, after destructive collection, mass production was determined dry. The results obtained indicated that the treatment that contained higher concentrations of mechanically separated tilapia meat residues in the substrate (160 kg N ha-1) showed greater growth in relation to the other treatments.
