“…However, achieving high productivity requires more than relying on the species adaptability. In addition, a group of silvicultural and management decisions must be thoroughly planned in order to meet growing conditions as optimal as possible, including understanding and matching edapho-climatic conditions (Fernández-Moya et al, 2015;Golfari, Caser, & Moura, 1978;Kaosa-ard, 1995;Medeiros, 2016;Pandey & Brown, 2000;Pelissari, Caldeira, V. S. Santos, & J. O. P. Santos, 2012;Ugulino, Latorraca, & Tomazello Filho, 2014), plant breeding, genotype prescription (Costa et al, 2015;Costa, Resende, & Silva, 2007; FAO (Food and Agriculture Organization of the United Nations), 2015; Schuhli & Paludzyszyn Filho, 2010) and other silvicultural prescriptions such as soil preparation and fertilization, planting spacing, thinning and pruning (FAO, 2009;Kaosa-ard, 1995;Pelissari, Caldeira, & Drescher, 2013).…”

The objective of the research was to assess the growth and structural changes of clonal and seed-origin teak trees in monoculture and agroforestry systems. The experiment was established in a randomized complete block design with six replicates. Eight treatments were etablished consisting of combinations of two propagation types (clonal and seed-origin), two types of cultivation systems until the age of 24 months (monoculture and taungya system with maize) and two types of cultivation system after 24 months of age (monoculture and silvopastoral systems). The data were analyzed by modeling the growth and yield, diameter distribution and diameter class ingrowth. The technical age of thinning was then determined by the percent entries method. Independent of the cultivation system, clonal trees presented greater tree height and diameter than seed-origin trees. Regarding the cultivation systems, systems ending in a monoculture phase presented greater tree height and diameter than systems ending in a silvopastoral phase. In terms of structure, represented by the evolution of diameter distribution, seed-origin trees and systems ending in a silvopastural phase resulted in flatter and broader distributions than clonal trees and final monoculture phase. Overall, the technical age of the first thinning varied from 6 to 9 years, being earlier for clonal trees in monoculture and later for seed-origin trees in systems ending in a silvopastoral phase. The slower growth and greater variability in silvopastoral systems with seed-origin teak tree can be attributed to the genetic variability of the trees associated competition with the brachiaria grass, which also made the plants more susceptible to the attack of pests.

“…Mollinedo Garcia (2003) indica não cultivá-la em áreas com pH inferior a 5,5, pois influencia no seu crescimento, aumentando as concentrações de alumínio que influencia negativamente no seu desenvolvimento. Com relação as exigências nutricionais, a teca tem seu desenvolvimento influenciado pela disponibilidade de potássio, (MORAES et al, 2008), é considerada uma espécie calcítica (PELISSARI et al (2012) e necessita de baixas concentrações de magnésio e altas concentrações de alumínio trocável que pode influenciar negativamente no seu desenvolvimento (MOLINEDO GARCIA, 2003).…”

“…De acordo com Pelissari et al (2012), o manejo da Teca, muitas vezes, é realizado com base em conhecimentos deficientes e inapropriados, o que dificulta estabelecer comparações entre os regimes de manejos adotados no mundo e as respostas das práticas silviculturais em locais com características edafoclimáticas distintas.…”

RESUMO: A pesquisa objetivou correlacionar atributos químicos do solo com variáveis de produção em um povoamento de Teca implantado em sistema silvipastoril. O presente estudo foi executado no município de Alta Floresta, Estado de Mato Grosso, em uma área de Sistema Silvipastoril (SSP). O estudo foi realizado em uma área de 118 ha com mudas de Teca de origem clonal. Para caracterização da área de estudo e posterior seleção das unidades amostrais, foi realizado um inventário florestal por meio de amostragem sistemática. As variáveis avaliadas foram: diâmetro à altura do peito (DAP), altura total (h), biomassa do tronco (BsT), galhos (BsG), folhas (BsF) e radicular (BsR). As bases apresentaram correlação positiva com o DAP, h, já o sódio (Na) e o magnésio (Mg) apresentaram correlação negativa com estas variáveis. A BsR e BsT correlacionaramse positivamente com a acidez potencial e a Matéria orgânica (MO) e negativamente com o Sódio (Na) e magnésio (Mg) (somente com BsR e BsG). A adubação e a correção dos nutrientes do solo são muito importantes para o crescimento e desenvolvimento da teca, sendo que as quantidades desses nutrientes nas diferentes profundidades interferem no seu desenvolvimento.

“…However, the conventional agricultural systems with monocultures must undergo transformations into systems that consider associations among agroecosystems (agroforestry systems), since these are sustainable methods for the production of food and forest products (Bonaudo et al, 2014), intending to soften the emission of greenhouse gases and offer improvements to the chemical attributes of the soil (Buller et al, 2015). However, most forest species cultivated have a high capacity to extract nutrients, causing significant impacts to the chemical attributes of the soils (Pelissari et al, 2012), and this high nutrient consumption may be intensified in agroforestry systems due to the introduction of new production components, such as annual grain production cultures.…”

The reuse of organic byproducts in agroforestry systems is a sustainable proposal, since, in addition to preserving the natural resources, it has allowed the fertilization of the soils, obtaining a reduction of costs with mineral fertilizers. Therefore, the objective of this research was to evaluate the chemical attributes of the soil after two years of successive fertilizations using cattle manure and sewage sludge in agroforestry systems. The study was conducted in Goiânia, state of Goiás, Brazil. The experimental design used randomized blocks on a 2 x 4 factorial (cultivation systems and fertilizations), with four repetitions. The cultivation systems were: agroforestry and monoculture systems. The fertilizations used were: cattle manure, sewage sludge, mineral fertilizer and control (no fertilization). Regardless of the cultivation system, the fertilizations with sewage sludge increases the calcium, phosphor and zinc contents of the soil, as well as the pH values, sum of bases and cation exchange capacity, at 0-10cm depth. However, the potassium contents are lower in relation to the use of mineral fertilizers, both at 0 to 10 cm depth and at 0 to 20 cm. Teak plants in agroforestry systems presents similar heights to the monoculture plants, and they are higher on fertilizations with sewage sludge. The soybean grain productivity in the agroforestry system presents similar outputs in relation to the use of sewage sludge and mineral fertilizers. Therefore, it is recommended for farmers to adopt agroforestry systems and the organic fertilization practice with sewage sludge, associating the quality of the chemical attributes of the soil, the growth of forest species and soybean grain yields.
