Abstract
The reuse of solid and liquid wastes has become a viable practice for the sustainability of agricultural production, because it meets the nutritional needs of crops and also allows the use of nutrients present in these residues. The objective of this work was to analyze the nutritional value of Tifton 85 irrigated with treated domestic wastewater and fertilized with nitrogen doses from poultry bed in four successive cuts, with frequency of 35 days. The experiment was set up in a protected environment, arranged in a completely randomized experimental design, in a 5 × 2 factorial scheme, with four replications. Five doses of nitrogen were tested through organic fertilization from avian beds (0, 15, 30, 45 and 60 kg N ha-1) and two irrigation water qualities (treated domestic well and artesian well). After the cuts the material was dried and sent to the laboratory to determine the following parameters- crude protein (CP), neutral detergent fiber (NDF) and Tifton 85 acid detergent fiber (ADF). The highest values of crude protein were obtained using the domestic wastewater treated in the irrigation, as well as using the higher doses of nitrogen from poultry litter. Just as the NDF and ADF contents presented the best values when treated domestic wastewater and the highest nitrogen doses. Indicating that irrigation with wastewater and the use of organic fertilizer may substitute for conventional manures by promoting satisfactory levels of concentrations for fodder.
