O trabalho objetivou estudar a formação de mudas de ipê-amarelo (Tabebuia chrysotricha Standl.) em função de quatro substratos, variando as soluções de adubação de cobertura. Para compor os substratos foi utilizada fibra de coco fibrosa e granulada formando os tratamentos 100% fibrosa (100% F), 60% fibrosa + 40% granulada (60% F+40% G), 40% fibrosa + 60% granulada (40% F+60% G) e 100% granulada (100%
G). A adubação de base foi igual para todos os tratamentos e as soluções de adubação variaram a fim de se obter soluções completas com condutividades elétricas de 1,06 dS m-1, 2,12 dS m-1, 3,2 dS m-1 e 4,24 dS m-1. As sementes foram colocadas diretamente nos tubetes (120mL) contendo os respectivos substratos e receberam as adubações por sub-superfície uma vez por semana, respeitando-se os tratamentos de adubação. Mudas produzidas em 100%G alcançaram maiores alturas e pesos de massa seca de parte
aérea em relação aos demais substratos. Soluções de fertirrigação menos concentradas favoreceram a formação de mudas mais altas e mais pesadas. As análises químicas da parte aérea foram obtidas quando as mudas estavam prontas para expedição (20 cm de altura). As mudas produzidas em substratos 100% F e 60% F+40% G apresentaram maiores teores de N, S, B, Mn e Zn na parte aérea. Recomenda-se a produção de mudas de ipê-amarelo (T. chrysotricha) em substratos contendo fibra de coco granulada e
soluções de adubação com CE de 1,06 dS m-1. |

The existence of degraded forests is common in the Eastern Amazon. The maintenance of these forests standing and the recovery of their productivity play an important role in the conservation of biodiversity, storage and carbon sequestration. However, the management techniques currently employed are designed for natural forests in the first harvest cycle or lightly explored and do not apply adequately to forests that have gone through several harvest cycles. Therefore, adaptations and the establishment of new management criteria that take into account other characteristics of these types of forests are necessary to ensure their sustainability. The objective of this study was to propose a silvicultural management system that has the potential to recover and perpetuate the productivity of an intensively logged tropical forest. A forest census was carried out on 535.6 ha for trees with dbh 25 cm. With these data, the following two treatments were designed: (1) criteria: the BDq method was applied from B = 9.8 m2 ha1, D = 100 cm and q = 2. The criteria for standing wood commercialization were, in this order, first, Health; second, Tree Stem; third, Tree Density and fourth, dbh 105 cm. (2) Control: the planning was in accordance with Brazilian regulations. For the cost?benefit and sensitivity analysis, the Net Present Value (NPV) was used and a projection of 20% was made in the commercial price of standing wood. In the criteria treatment, a higher number of trees and species destined for the commercialization of standing wood was verified in relation to the control treatment, showing a greater diversity of species. In the criteria treatment, NPV was positive and superior to the control treatment in all scenarios. The proposed silvicultural management system with an object of an explored and enriched forest, with criteria for harvesting trees with a minimum cut diameter of 25 cm, proved to be viable to generate economic returns and with conservationist potential for the continuous supply of forest products and maintaining biodiversity.
