Abstract

Every activity developed by human beings needs some form of use of natural resources, in which available water resources have been compromised in recent decades. One way to mitigate environmental impacts is to seek alternatives for their supply. Thus, a measure that has been disseminated is the use of treated domestic sewage in agriculture, which can guarantee an increase in production due to the greater supply of nutrients and organic matter. Allied to this, the expansion of the market in the cultivation of flowers and ornamental plants, makes the farmer look for soilless cultivation systems, which provide higher quality cultivation as in the case of anthurium. Thus, the objective of this work is to evaluate the production potential in soilless cultivation of anthurium (Anthurium Andraeanum) using treated domestic sewage as a source of water and nutrients. The experiment will be carried out in an agricultural greenhouse, the chosen system is the cultivation without fertigated soil (also known as semi hydroponic) and will have three treatments: (TA) drinking water plus chemical fertilizers, (TRA) reuse water complemented with fertilizers, ( TR) only reuse water, the experimental design will be in completely randomized blocks. The quantitative and qualitative results of anthurium culture will be evaluated through analysis of variance followed by Tukey's test at 5% probability. It is expected that the use of treated domestic sewage provides water and nutrients input to the crop, guaranteeing production and reducing the use of water and chemical fertilizers with environmental safety.
