Abstract

The objective of this study was to analyze the use of hog production wastewater in the production of seedlings of Eucalyptus urophylla, using a compound of municipal solid waste (SRSU) as substrate, and evaluating the effect of different proportions of ARS and of seedling ages in their morphological and nutritional quality. The experiment was conducted in a greenhouse at the Experimental Hydraulics, Irrigation and Drainage, Department of Agricultural Engineering. The statistical design was randomized blocks with different numbers of repetitions, consisting of 10 treatments in a 5 x 2 factorial design (5 proportions of ARS supplemented with nitrogen fertilization and 2 seedling ages). The variables measured were shoot height (H), stem diameter (SD), shoot dry matter (SDM), root dry mass (RDM), total dry matter (TDM), ratio of seedling height / diameter of the girth (H / SD), ratio of dry weight of shoot / root dry mass (SDM / RDM), Dickson quality index (DQI) and concentrations of nutrients in the plants leaf, stem and root. These characteristics were evaluated at 75 and 90 days after seeding (DAS). It was concluded that the proportion of 50% ARS improved the nutritional and morphological characteristics of eucalyptus. The seedlings achieved morphological characteristics suitable for planting in the field 90 days after sowing and showed appropriate levels for most nutrients at both ages.
