SUBSTRATES OF ORGANIC ORIGIN FOR PRODUCTION OF SEEDLINGS OF TEAK (Tectona grandis Linn . F.). Ciênc. Florest. [online]. 2013, vol.23, n.3, pp.401-409.

The utilization of renewable waste as a source of nutrients for forest seedlings production can be a solution to environmental problems, mainly related to the disposal of these materials. In this context, this study aimed to evaluate the use of renewable substrates as substrate components in the production of teak seedlings. Seedlings were grown in tubes with a volume capacity of 280 cm³, using for the composition of treatments cattle manure, poultry litter or manure quail associated with subsoil earth and a fraction of 25% of commercial forestry substrate, and the formed substrates were subjected to chemical analysis. Ninety days after transplanting the seedlings, the following morphological characteristics were analyzed: shoot height, stem diameter, dry weight of shoots, roots and total and Dickson quality index. The results indicated that the seedlings produced with substrates formulated with poultry litter had the highest growth from the traits studied, given that the treatment with 35% of this material provided the greatest gains. The use of renewable substrates may be indicated for forest seedling production, contributing for the improvement of the chemical properties of substrates formed and consequently for the plant nutrition.
