Domestic Effluent Treated for the Cultivation of Anthurium (Anthurium Andraeanum Lind.)

Abstract

Purpose: The objective of this research was to evaluate the growth and production of anthurium (Anthurium andraeanum Lind.) irrigated with dilutions of treated domestic effluent (EDT), aiming to reduce the use of water and recycle the nutrients present in the effluent. Theoretical framework: Faced with the scarcity and irregularity of rainfall in the Recôncavo da Bahia, it emphasizes the need and urgency in the search for alternative sources of water for irrigation, such as wastewater, with the potential to supply the water and nutritional demands of plants, especially those with less restriction, like ornamentals. Method/design/approach: The experimental design was completely randomized, using five dilutions of EDT (0, 25, 50, 75 and 100%) in drinking water, with four replications. Plant height, number of leaves, leaf area, number of flowers and shoot dry mass were evaluated. Results and conclusion: Plants irrigated with EDT dilutions and fertilized with 50% of the recommended nitrogen and potassium showed growth and production similar to plants irrigated with water supply and fertilized with 100% of the recommended mineral fertilizer, which allows recommending the use of EDT for irrigation of anthurium with 50% reduction of mineral fertilization. Research implications: The results obtained reinforce the importance of taking advantage of the nutrient content present in the effluent, with the possibility of partially replacing mineral fertilizers, favoring savings in quality water and mineral fertilizers. Originality/value: Savings of good quality water and mineral fertilizers, in addition to providing a safe destination for the effluent.
