Seedlings of Euterpe Edulis Mart Production from Agroindustry Waste and Sewage Sludge Substrates.

The search for alternatives to environmentally friendly disposal of sewage sludge has been one of the biggest challenges in wastewater treatment processes, and the use of these materials in the production of forest seedlings are emerging as a promising technique. This study evaluated the use of organic compounds produced from agro-industrial residues of peach palm and sewage sludge with different levels of fertilizer as a substrate for production of Euterpe edulis Mart seedlings, a kind of endangered Atlantic Forest; and compare seedling growth with substrates of sewage sludge and a commercial substrate. A completely randomized design (CRD) was used in a factorial 3 x 4, with 3 substrates of sewage sludge and residues from agriculture palm peach, 4 levels (0, 2.0, 4.0 and 6.0 g dm^-3) granular fertilizer and a commercial substrate. Were measured diameter, plant height, H / D, dry matter of shoots, root dry matter and macronutrients in the shoot. The use of substrate composed sewage sludge + peach palm 1:1 v: v, resulted in the production of seedlings of E. edulis with best quality; Increased doses of granulated fertilizer resulted in significant effects on seedling quality, and use economically viable dose of 2.0 g L-1 of this fertilizer. The use of sewage sludge and bark of peach palm viability as a substrate in the production of seedlings of this species, representing an environmental safe alternative.
