The experiment was conducted at a greenhouse in the period from July to August 2010. The following treatments were conducted: Treatment Witness (TW) = 0% of sludge; Treatment 2 (T2) = 2% of sludge; Treatment 4 (T4) = 4% of sludge; Treatment 6 (T6) = 6% of sludge, Treatment 8 (T8) = 8% of sludge; Treatment 10 (T10) = 10% of sludge, mixed to commercial substrate. The experiment was conducted in trays for 30 days, where were done the evaluations of emergency and growth of the seedlings. The tannery¡¯s sludge in dosages employed provided a raise in the growth of the lettuce¡¯s seedlings. %K Seedling production %K Lactuca sativa %K Waste %U dx.doi.org/10.5747/ce.2011.v03.n1.e023
