Biomass production of the aquatic macrophyte Ceratopteris pteridoides (Hook.) Hieron (Pteridaceae) in nutrient addition treatments

Aquatic macrophytes are a key group in flooded areas due to their high primary productivity, and several species present the Amazonian floodplains have potential for human food use. This study evaluated biomass production nutrient levels fronds of Ceratopteris pteridoides (Pteridaceae), under following nutritional treatments: (T1) artesian well water, (T2) natural lake (T3) water with nutritive solution. Each replicate had 25 plants g total fresh each. The experiment lasted 35 days weight, root system length, leaf dry weight sprout number were assessed. from T3 greatest increase an average 430.02 g, showing that solution used provided best conditions plant growth. daily ingestion C. could contribute mineral supplementation, addition diversifying existing crops contributing sustainable agriculture.
