Resumo: The objective of this work was to assess the current monthly increment in diameter of eucalyptus (Eucalyptus grandis x Eucalyptus urophylla) trees in response to different production systems, climatic factors, and thinning. The trees were evaluated in four production systems: monoculture and crop-forestry, livestock-forestry, and crop-livestock-forestry integration. The increment in diameter of 80 trees was measured monthly from May 2015 to May 2019. The effect of the climatic variables was determined through correlation and multiple regression analyses. The increment in current monthly diameter is seasonal and highly dependent on accumulated rainfall. The adopted modeling allowed concluding that both water shortage and excess (30 and 475 mm per month, respectively) decreased tree growth in diameter. The trees in the integrated systems showed a higher growth in diameter than those under monoculture, and intercropping with crops resulted in a greater diameter growth than that with pasture. Thinning accelerates the growth of the remaining trees, with an effect of higher magnitude and longer duration in the integrated production systems.

As árvores foram avaliadas em quatro sistemas de produção: monocultivo e integração lavoura-floresta, pecuária-floresta e lavoura-pecuária-floresta. O incremento em diâmetro de 80 árvores foi avaliado mensalmente de maio de 2015 a maio de 2019. O efeito das variáveis climáticas foi determinado pelas análises de correlação e regressão múltipla. O incremento corrente mensal em diâmetro é sazonal e altamente dependente da precipitação. A modelagem adotada permitiu concluir que tanto a falta quanto o excesso de água (30 e 475 mm por mês, respectivamente) reduziram o crescimento das árvores em diâmetro. As árvores nos sistemas de integração crescem mais do que as em monocultivo, e o consórcio com a lavoura resultou em maior crescimento em diâmetro do que o com a pastagem. O desbaste promove a aceleração no crescimento das árvores remanescentes, com efeito de maior magnitude e duração nos sistemas integrados de produção.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraTonini, HelioMorales, Mariana MouraMagalhaes, Ciro Augusto de SouzaSilva, Vanderley Porfirio da2022-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26984Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02544Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e025441678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26984/14963Direitos autorais 2022 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/26984Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
