Abstract

The high consumption of water in irrigated agriculture and lack of alternative water sources make the reuse of sewage water a highly promising option in this activity. This research has as objective to evaluate the effect of treated sewage effluent (TSE) application, via fertirrigation, on soil and on Brachiaria crop, by quantifying of: a) response of dry matter yield and forage quality of Brachiaria to the application of TSE, b) export of macro and micronutrients from the soil by harvesting forage, and d) changes in physical and chemical properties of soil. Brachiaria brizantha cv. Marandu will be cultivated under irrigation with different application rates obtained from the TSE Treatment Plant Sewer of Jaboticabal, SP. The experiment will be conducted in the experimental area of the Rural Engineering Department at FCAV-UNESP. Five treatments will be established, corresponding to different application rates of TSE, with four replications. The evaluations will consist of monitoring of chemical and physical characteristics of the soil profile, accumulation of crop mass, leaf area index, nutrients in plant tissue and nutritional quality of pasture harvested during the experimental period. With these results will be adjusted response functions of forage yield to applications of TSE, adjusted curves and nutrient concentrations in Brachiaria leaf and soil as a function of the applied amounts of TSE.
