Summary:This study aimed to evaluate the effect of different proportions of ARS (Swine Wastewater) and two ages of seedlings of Eucalyptus urophylla in their morphological quality. The experiment was conducted at the Experimental Hydraulics, Irrigation and Drainage Department of Agricultural Engineering, Federal University of Vicosa (UFV), in Vicosa, Minas Gerais state, in a greenhouse. The experiment consisted of 10 treatments in a factorial 5 x 2 (5 proportions of ARS supplemented with nitrogen fertilization and seedling age 2) with different number of repetitions, and the experimental design was a randomized block. To track the growth of seedlings of the species studied were evaluated at 75 and 90 days after sowing, the following morphological characteristics: height of shoot (H), stem diameter (CD), shoot dry mass (SDM), root dry mass (RDM), total dry matter (TDM), seedling height raltionship/collar diameter (H/CD), shoot dray mass ratio/root dry mass (SDM/MSR) and Dickson quality index (IQD). The results showed that the proportion of 50% of ARS is the one which results in the best morphological characteristics of eucalyptus seedlings. The seedlings showed the planting in the field only 90 days after sowing.
