Resumo: | Forest intercropping with nitrogen-fixing species can provide an increase in eucalyptus yield. The objective of this study was to evaluate growth and yield in monospecific and mixed stands of Eucalyptus urograndis and Acacia mearnsii, in Bagé, Rio Grande do Sul State, Brazil. Treatments were 100E (100% eucalyptus), 100A (100% black wattle), 50E:50A (50% eucalyptus + 50% black wattle), 75E:25A (75% eucalyptus + 25% black wattle), and 25E:75A (25% eucalyptus + 75% black wattle). The first evaluation was carried out at the age of 6 months (diameter at stem and total height) and the second at 18 months (diameter at breast height, total height, volume with bark, and leaf area index). The Eucalyptus urograndis and Acacia mearnsii diameter and total height growth, for both 6 and 18 months, did not differ among treatments. The total wood yield (m3 ha-1) was the same for cropping and intercropping, without any influence from other species. The mixed cropping system resulted in a greater number of individuals with higher diameters (? + 1?), when compared to the cropping system, offering the forester an opportunity to obtain multiple products from his/her forest, due to a greater assortment provided by the presence of the two species. |

O interplantio de leguminosas arbóreas fixadoras de nitrogênio pode proporcionar incremento na produtividade das plantas de eucalipto. Objetivou-se, com este estudo, avaliar o crescimento e a produtividade de povoamentos monoespecíficos e mistos de Eucalyptus urograndis e Acacia mearnsii, no município de Bagé (RS). Os tratamentos estudados foram os seguintes: 100E (100% de eucalipto), 100A (100% de acácia-negra), 50E:50A (50% de eucalipto + 50% de acácia-negra), 75%E:25%A (75% de eucalipto + 25% de acácia-negra) e 25E:75A (25% de eucalipto + 75% de acácia-negra). A primeira avaliação do crescimento foi realizada aos 6 meses de idade (aferição do diâmetro do coleto e altura total) e a segunda aos 18 meses (diâmetro à altura do peito, altura total, volume com casca e índice de área foliar). O crescimento em diâmetro e a altura total do Eucalyptus urograndis e da Acacia mearnsii, tanto aos 6 como aos 18 meses, não diferiram entre os tratamentos. A produção total de madeira (m3 ha-1) foi a mesma no consórcio e no monocultivo, não havendo influência da presença de outra espécie. O cultivo misto resultou em maior número de indivíduos com diâmetros superiores (µ + 1?), em relação aos monocultivos, proporcionando, ao silvicultor, a obtenção de produtos múltiplos de sua floresta, devido a um maior sortimento proporcionado pela presença de duas espécies florestais.Escola de Agronomia - Universidade Federal de Goiás2011-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa experimentalapplication/pdfhttps://revistas.ufg.br/pat/article/view/10760Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 41, n. 3, Jul./Sep. 2011; 415-421Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 41, n. 3, jul./set. 2011; 415-421Pesquisa Agropecuária Tropical; v. 41, n. 3, jul./set. 2011; 415-4211983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/10760/9692Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessViera, MárcioSchumacher, Mauro ValdirLiberalesso, Edenilson2020-07-09T19:15:11Zoai:ojs.revistas.ufg.br:article/10760Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:49.821362Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |

The first evaluation was carried out at the age of 6 months (diameter at stem and total height) and the second at 18 months (diameter at breast height, total height, volume with bark, and leaf area index). The Eucalyptus urograndis and Acacia mearnsii diameter and total height growth, for both 6 and 18 months, did not differ among treatments. The total wood yield (m3 ha-1) was the same for cropping and intercropping, without any influence from other species. The mixed cropping system resulted in a greater number of individuals with higher diameters (? + 1?), when compared to the cropping system, offering the forester an opportunity to obtain multiple products from his/her forest, due to a greater assortment provided by the presence of the two species. |
