“…Fontanetti et al (2014) found a percentage of soil coverage of 52 %, for Calopogonium sown at the maize V4 stage. On the other hand, Teodoro et al (2011), evaluating different green manures, including monocultures of Calopogonium, perennial soy, tropical kudzu, forage peanut and stylosanthes, found that Calopogonium, forage peanut and tropical kudzu completely covered the soil (100 %) at 120 DAS of green manure.…”

“…In the study by Teodoro et al (2011), it must be emphasized that green manures were grown in monoculture, that is, they did not compete for production factors (light, water and nutrients) with maize plants, and the spacing between sowing lines was 0.40 m. These factors likely contributed to a higher soil cover. Lima et al (2014) suggested increasing the seeding density of green manures and adjusting the arrangement (spacing) of the plants as options to increase soil coverage by the same green manures evaluated in this experiment.…”

Maize intercropped with perennial green manure is an option to promote soil coverage, control weeds and recycle soil nutrients, in an organic system. This study aimed at evaluating the agronomic characteristics and yield of grains and organic maize straw intercropped with perennial green manures sown at different maize growth stages. A 3 x 2 + 1 factorial design was used, with three perennial species of green manure - calopogonium (Calopogonium mucunoides Desv.), tropical kudzu [Pueraria phaseoloides (Roxb.) Benth] and perennial soy [Neonotonia wightii (Wight & Arn) Lackey] - and two green manure sowing times - at the maize V4 (four expanded leaves) and VT (bolting) stages - plus a control treatment (maize monoculture). A randomized blocks design, with four replications, was used. Soil coverage, production of green manures dry matter and weeds, and maize growth and production variables were evaluated. The sowing of green manures at the V4 stage had a higher percentage of soil coverage, in relation to the VT stage. Calopogonium, when compared to the other green manure species, had the highest percentage of soil coverage (35.63 %) and dry matter (1.0 Mg ha-1). Perennial green manures grown intercropped with maize did not affect growth, grain yield and maize straw. However, they were not effective in suppressing weeds.

“…Estes procedimentos protegem o solo contra a erosão, trazem benefícios à fertilidade e estrutura do solo devido à elevação do teor de matéria orgânica, e melhora a amplitude térmica do solo mantendo sua umidade, o que possibilita um melhor desempenho das culturas (AMOSSÉ; JEUFFROY; DAVID, 2013;CAMPIGLIA et al, 2010;NAKHONE;TABATABAI, 2008;SALMERÓN;ISLA;CAVERO, 2011;TEODORO et al, 2011).…”

As subparcelas em número de três, foram compostas por: 1 -pulverização apenas de herbicida de manejo antes da semeadura do milho; 2 -herbicida de manejo após a semeadura do milho + herbicida residual, e 3 -testemunha sem aplicação de herbicidas. As coberturas mortas de aveia-preta e nabo-forrageiro proporcionam as menores densidades de plantas daninhas e acúmulos de massa seca da comunidade infestante, independente da aplicação ou não de herbicidas. Houve uma maior germinação de B. pilosa nas parcelas mantidas com a cobertura de tremoço, com exceção das subparcelas onde se aplicou herbicida em pré-emergência, o que evidencia um efeito estimulante da cobertura morta. O emprego de algumas espécies na formação da cobertura morta para o plantio direto pode dispensar ou reduzir a quantidade de herbicidas necessária para o controle das plantas daninhas. Palavras-chave:Herbicida. Plantio direto. Resíduo vegetal. Rotação de culturas. Zea mays L.. ABSTRACT -The correct choice of cover crops improves the sustainability of a farming system, as it can enhance the use of herbicides, reduce weed infestation and improve crop performance. With the aim of studying the effect of winter mulches and the use of herbicides on a community of weeds in maize, a study was carried out in a completely randomised design where the treatments were arranged in a scheme of split lots with four replications. The lots, six in number, comprised the following winter crops: Lupinus albus, sativos Lathyrus, Triticum aestivum, Avena strigosa, Raphanus sativus, and a control kept fallow. The three sub-lots comprised, 1 -spraying the management herbicide before sowing the maize, 2 -management herbicide after sowing the maize + residual herbicide, and 3 -control without the application of herbicide. Mulches of black oat and forage turnip gave the lowest weed densities and accumulations of dry weight in the weed community, irrespective of the application of herbicide. There was greater germination of B. pilosa in the lots maintained with a cover of lupins, with the exception of those sub-lots where herbicide was applied pre-emergence, demonstrating the stimulating effect of mulch. The use of certain species in the formation of mulch under direct planting can dispense with or reduce the amount of herbicides needed for weed control.

“…Para esse manejo pode-se utilizar espécies vegetais de rápido crescimento para a produção de fitomassa e espécies vegetais herbáceas de hábitos perenes, que permanecem por mais tempo em companhia das culturas principais (PERIN et al, 2004;RAGOZO et al, 2006;TEODORO et al, 2011) A utilização de leguminosas herbáceas, como plantas de cobertura, aponta a possibilidade de melhorias em diversos atributos do solo, associado à minimização dos agentes erosivos, aporte de nitrogê-nio atmosférico, ciclagem de nutrientes, manutenção da umidade e menor amplitude térmica do solo, favorecendo a atividade de microrganismos benéficos no solo (GUERRA et al, 2004;SMITH, 2008). Entretanto, Perin et al (2009) recomendam alguns cuidados específicos quanto a escolha das leguminosas a serem utilizadas, assim como espécies com tempo e hábito de crescimento condizente com o manejo da cultura de interesse econômico e outros efeitos da convivência, reduzindo ao máximo os riscos de competição.…”

RESUMO -Este trabalho teve como objetivo avaliar o crescimento vegetativo e a produtividade da bananeira cv. "Nanicão" cultivada sobre coberturas de solo com leguminosas herbáceas perenes no semiárido. O delineamento experimental foi em blocos casualizados, com quatro repetições, em esquema de parcelas subsubdivididas no tempo, sendo nas parcelas o fator "A" constituído por três manejos de cobertura do solo, pelas leguminosas cudzu tropical (Calopogonium mucunoides), calopogônio (Pueraria phaseoloides) e solo descoberto (solo capinado), fator "B" nas subparcelas e plantas de bananeiras em três idades morfofisiológicas (diferentes ciclos e tamanhos), e o fator "C" datas das coletas nas subparcelas. O cultivo de bananeira em solo sob cobertura viva com calopogônio e cudzu tropical na região do semiárido promoveu aumento no número e peso do fruto, pencas e cachos.Palavras-chave: Adubação verde.

PERFORMANCE OF BANANA "Nanicão" ON LIVE COVERAGE OF SOIL IN SEMIARIDABSTRACT-This work aimed to evaluate the growth and yield of banana cv. "Nanicão", in intercropping with live coverage crops in the semi-arid region. The experiment was analysed as a randomized complete block with four replications. The experiment used a split-plot design, and some variables were sub-subdivided over time. In the plots, factor "A", made of three management strategies of soil cover -the leguminous, calopo and tropical kudzu, and bare soil (hoed soil); Factor "B", on the sub-plots, banana plants in three morphophysiological ages (different cycles and sizes) and factor "C", dates of collections in the sub-plots. The cultivation of banana cv. Nanicão in soil under live coverage with calopo and tropical kudzu in the semi-arid region promotes an increase in the number of fruits, fruit weight and bunches.
