Resumo: | In Vitória da Conquista, Bahia, Brazil, intercropping with grevillea (Grevillea robusta A. Cunn) was implemented to reduce damage caused by wind speed in a coffee (Coffea arabica L.) plantation. As a consequence, many other factors, like reduction in solar radiation incidence, air temperature, soil moisture maintenance and increase in soil organic matter content were also observed. Such changes in the environment alters the number of plants and behaviour of coffee plants as well as other biotic components of this agroecosystem. This work deals with grevillea densities intercropped in coffee plantations and its relation to weed diversity and density. The experiment was carried out from April 2004 to March 2005 on six observation fields with different revile arrangements in coffee plantations (T1: 6x6m, T2 : 6x12m, T3: 12x9m, T4:9x9m, T5:9x18m, T6:18x18m) and a coffee field maintained in a full sunshine exposition (T7). Coffee crop spacing was one meter in row between plants and three meters between rows. Weed observations revealed 21 species; five Dicotyledons and 16 Monocotyledons. The highest weed diversity indexes were observed in fields with greater density of grevillea trees. Tree intercropping in coffee fields influenced weed density, frequency and diversity in comparison to coffee exposed to full sunshine. |

Entretanto, muitos outros efeitos como a redução da variação da temperatura do ar e da incidência da radiação solar, a manutenção da umidade e elevação da matéria orgânica do solo também foram observados. Tais alterações afetam a população de plantas de café, assim como o comportamento de outros componentes bióticos desse agroecossistema. O presente trabalho foi realizado com o intuito de investigar a relação entre os cafezais (Coffea arabica L.) arborizados com diferentes densidades de grevíleas (Grevillea robusta A. Cunn) e a diversidade e freqüência de plantas daninhas infestantes. O experimento foi composto por seis campos de observação definidos por diferentes espaçamentos de grevíleas nos cafezais arborizados (T1: 6 X 6 m, T2: 6 X 12 m, T3: 12 X 9 m, T4: 9 X 9 m, T5: 9 X 18 m, T6:18 X 18 m) e um campo a pleno sol (T7). Os cafeeiros foram dispostos no espaçamento de três metros nas entrelinhas e um metro entre plantas, na linha. Foram identificadas 21 espécies de plantas daninhas, cinco espécies monocotiledôneas e 16 espécies dicotiledôneas. Os maiores índices de diversidade de plantas daninhas foram verificados nos campos com maiores números de árvores de grevíleas. A arborização nos cafezais influenciou a densidade, freqüência e a diversidade de espécies de plantas daninhas quando comparado com cafezais mantidos a pleno sol.Editora UFLA2007-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfapplication/pdfhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/28Coffee Science - ISSN 1984-3909; Vol. 1 No. 2 (2006); p. 126-134Coffee Science; Vol. 1 Núm. 2 (2006); p. 126-134Coffee Science; v. 1 n. 2 (2006); p. 126-1341984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporengspahttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/28/24https://coffeescience.ufla.br/index.php/Coffeescience/article/view/28/102https://coffeescience.ufla.br/index.php/Coffeescience/article/view/28/103Copyright (c) 2007 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessSilva, Shirley de OliveiraMatsumoto, Sylvana NaomiBebé, Felizarda VianaJosé, Alcebíades Rebouças São2013-02-23T12:25:31Zoai:coffeescience.ufla.br:article/28Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:26.697984Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true |
