Title A name given to the resource Phytosociological aspects and weed management using cover crops on organic conilon coffee plantations / <br> Aspectos fitossociológicos e manejo de plantas espontâneas utilizando espécies de cobertura em cafeeiro Conilon orgânico Creator An entity primarily responsible for making the resource Henrique Duarte Vieira, Fábio Luiz Partelli, José Antonio Azevedo Espindola, Silvério de Paiva Freitas Description An account of the resource Weeds can bring benefits to agriculture, but when incorrectly managed they can compete with commercial crops for resources. The objective of this work was to evaluate the effect that cover crops, associated with Coffea canephora cv. Conilon, imposes to the weed community. Cover crops were planted between the rows of a 6.5 years old organic coffee plantation spaced 2.0 x 1.5 m. The experiment was arranged in a complete randomized block design, with four replications, in a factorial scheme with the following treatments: control, Pennisetum glaucum and the legume plants: Canavalia ensiformis, Mucuna deeringiana and Cajanus cajan, with and without Rizobium inoculation. Cover crops dry weight and nutrient contents on coffee trees were determined. Weeds density, frequency, relative abundance, importance value index and plant similarity index were also determined. Twenty seven weed species were identified, with special emphasis on Bidens subalternans and Commelina benghalensis. Cover crops promote modifications on the succession dynamics of weeds and do not interfere with the development of the coffee trees. Canavalia ensiformis, Mucuna deeringiana and Pennisetum glaucum help on weed control.As plantas espontâneas competem com as culturas por recursos escassos, quando mal manejadas. No entanto, podem trazer benefícios à agricultura. O objetivo desse trabalho foi avaliar o efeito que plantas de cobertura, consorciadas com Coffea canephora cv. Conilon, impõem à comunidade de plantas espontâneas. Plantas de cobertura foram semeadas nas entrelinhas de um cafezal de 6,5 anos conduzido sob manejo orgânico, com espaçamento de 2,0 x 1,5 m. O delineamento experimental foi de blocos ao acaso, com quatro repetições, num arranjo fatorial com tratamentos adicionais: testemunha, milheto – Pennisetum glaucum, e as leguminosas feijão-de-porco – Canavalia ensiformis, mucuna-anã – Mucuna deeringiana, e feijão-guandu – Cajanus cajan, com e sem inoculação com rizóbio. Foram determinados a matéria seca das plantas de cobertura e as concentrações de nutrientes no cafeeiro. Determinou-se ainda a densidade, frequência e abundância relativas, assim como o índice de valor de importância e de similaridade das plantas espontâneas. Foram identificadas 27 espécies, destacando-se Bidens subalternans e Commelina benghalensis. As espécies de cobertura promovem modificações na população de plantas espontâneas e não prejudicam o cafeeiro. Feijão-de-porco, mucuna-anã e milheto auxiliam na supressão de plantas espontâneas.
