The experiment was conducted atthe Experimental Hydraulics, Irrigation and Drainage Department of Agricultural Engineering, FederalUniversity of Viçosa (UFV), in Viçosa, Minas Gerais state, in a greenhouse. The experiment consistedof 10 treatments in a factorial 5 x 2 (5 proportions of ARS supplemented with nitrogen fertilization andseedling age 2) with different number of repetitions, and the experimental design was a randomizedblock. To track the growth of seedlings of the species studied were evaluated at 75 and 90 days aftersowing, the following morphological characteristics: height of shoot (H), stem diameter (CD), shoot drymass (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 resultsshowed that the proportion of 50% of ARS is the one which results in the best morphological characteristicsof eucalyptus seedlings. The seedlings showed the planting in the field only 90 days after sowing.
