Este trabalho foi desenvolvido com o objetivo de comparar a alocação da biomassa arbórea, a conicidade do tronco e a relação altura e diâmetro ao longo do fuste de árvores de eucalipto implantadas em um sistema silvipastoril, em diferente exposição solar, e em monocultivo. Os dados foram coletados em 13 árvores-amostra aos 27 meses de idade, selecionadas em função do intervalo de confiança da média dos diâmetros a altura do peito (DAP) e da posição das árvores na faixa de plantio, com face de exposição sul, norte e central. Concluiu-se que na comparação com o monocultivo, as árvores plantadas em sistema silvipastoril apresentaram menor altura total, maior conicidade e maior biomassa na copa. No sistema silvipastoril, não houve efeito da posição da árvore na faixa de plantio sobre a produção total de biomassa na parte aérea, porém, árvores com face de exposição norte foram mais baixas, cônicas e produziram maior biomassa de galhos e folhas nas partes inferiores da copa. Palavras-chave: Sistemas agroflorestais; Conicidade do tronco; Produtividade Abstract This work was developed in order to compare the arboreal biomass allocation, trunk taper, height and diameter ratio, along the stem of eucalyptus trees planted in silvopastoral system in different sun exposure and monoculture. The data were collected from 13 trees at 27 months, selected according to confidence interval average of breast height diameter (DAP) trees position in planting strip, sun exposure (face south, north and central). It was found that compared to the monoculture, the trees planted in silvopastoral system had lower overall height, larger taper and higher biomass in pantry. There was no sun exposure effect for planting strip and total biomass for silvipastoral systems, however, trees with north sun exposure were lower, more conical, produced more branches and leaves in the lower parts of the treetops.

The silvopastoral system (SPS) has been suggested to ensure sustainability in animal production systems in tropical ecosystems. The objective of this study was to evaluate pasture characteristics, herbage intake, grazing activity and milk yield of Holstein×Zebu cows managed in two grazing systems (treatments): SPS dominated by a graminaceous forage (Brachiaria decumbens) intercropped with different leguminous herbaceous forages (Stylosanthes spp., Pueraria phaseoloides and Calopogonium mucunoides) and legume trees (Acacia mangium, Gliricidia sepium and Leucaena leucocephala), and open pasture (OP) of B. decumbens intercropped only with Stylosanthes spp. Pastures were managed according to the rules for organic cattle production. The study was carried out by following a switch back format with 12 cows, 6 for each treatment, over 3 experimental years. Herbage mass was similar (P>0.05) for both treatments, supporting an average stocking rate of 1.23 AU/ha. Daily dry matter intake did not vary (P>0.05) between treatments (average of 11.3±1.02 kg/cow per day, corresponding to 2.23±0.2% BW). Milk yield was higher (P<0.05; 10.4±0.06 kg/cow per day) in the SPS than in the OP (9.5±0.06 kg/cow per day) during the 1st year, but did not significantly differ (P>0.05) in subsequent years. The highest (P<0.05) values for herbage mass and milk yield were observed during the 3rd year. In the SPS, with moderate shade (19% shade relative to a full-sun condition), the grass CP was higher (P<0.05) than in the OP, although the NDF content and digestibility coefficient were not modified. The animals spent more time (P<0.05) idling in the SPS than in OP. The higher legume proportion in the SPS was associated with the higher CP level in B. decumbens relative to the OP, which could explain the better (P<0.05) performance of the cows in silvopastoral areas during the 1st year. However, during the 2nd and 3rd years, similarities in the legume percentages of both systems resulted in similar (P>0.05) milk yields. Low persistence of Stylosanthes guianensis was observed over the experimental period, indicating that the persistence of forage legumes under grazing could be improved using adapted cultivars that have higher annual seed production. The SPS and a diversified botanical composition of the pasture using legume species mixed with grasses are recommended for organic milk production.
