Produção da arruda (Ruta graveolens L.) cultivada com resíduo orgânico

Abstract

The main aroma of Rue (Ruta graveolens L.), which exudes from the entire plant, is attributed to rutin, to which the multiple medicinal activities of the plant are largely attributed, among them, protecting the capillary endothelium and reducing triacylglycerol levels. It performs significant functions in the organism, the most important being the increase in the resistance of the blood capillaries, preventing their rupture and the resulting hemorrhages. Rue has about 0.15% essential oil, especially in leaves and flowers. The objective of this work was to evaluate the use of organic poultry litter residues in the production of biomass and rue essential oil. Chicken manure (10 t ha-1 ) was used under four application forms (Incorporated, Coverage, Incorporated + Coverage and Without residue), arranged as a 2 x 4 factorial, in a randomized block experimental design, with four replications. The plants were harvested at 165 days of cycle and the production of leaf and stem biomass and leaf area and the essential oil content of the leaves were evaluated by hydro distillation using steam distillation. Plant heights grew linearly with the use of chicken manure and quadratically with the use of organosuper up to 165 days of cycle, with a final average of 33 cm. There was no significant interaction between the types of residue and forms of application or the type of residue on the production of rue. On the other hand, in the presence of residue, the production of rue was higher, regardless of the form of application. The lowest productions were in the absence of the residue. The essential oil content was not influenced by the types or forms of residue incorporation, with an average content of 0.1%. Based on the results obtained and considering the morphological part used medicinally, it is recommended to use chicken litter incorporated into the soil for the production of rue plant leaves.
