- Abstract
Using Buchenavia tomentosa (tarumarana) in forest restoration requires information on the best conditions for seedling production. Therefore, the present work aimed to evaluate the influence of different organic materials or combinations of these materials, and their effects on dry biomass, N content and physiological characteristics of tarumarana seedlings. The experiment was carried out in a completely randomized design with 10 treatments: T0 - 100% CS; T1 - 50% CS + 50% poultry manure (PM); T2 - 50% CS + 50% equine manure (EM); T3 - 50% CS + 50% bovine manure (BM); T4 - 50% EM + 25% BM + 25% CS; T5 - 50% BM + 25% EM + 25% CS; T6 - 50% PM + 25% BM + 25% CS; T7 - 50% EM + 25% PM + 25% CS; T8 - 50% BM + 25% PM + 25% CS; T9 - 50% PM + 25% EM + 25% CS. The highest mass productions were found in 50% CS + 50% EM (T2) and; 50% BM + 25% PM + 25% CS (T8) and six repetitions. The seedlings conducted in the T8 substrate showed a higher photosynthetic rate, stomatal conductance, CO2 concentration and transpiratory rate, which have as a consequence, the highest mass production of plants.
