| ABSTRACT This research aimed to evaluate the yield and economic viability of three crop cycles of the banana cv. ‘Prata Anã’ in association with perennial herbaceous legumes, natural vegetation, or compared with the conventional management. The research was conducted using a complete randomized block design with split-split plots and four replicates. The plots were formed by four irrigation depths: 50, 75, 100 and 125% of crop evapotranspiration, and the subplots by cover crops (Calopogonium muconoides, Pueraria phaseoloides, and natural cover without N addition) or no cover crops with addition of N fertilization (conventional management). The subsubplots were formed by the second, third and fourth banana production cycles. Yield and economic viability of... |

| ABSTRACT The aim of this study was to evaluate the initial growth of sunflower seedlings under different concentrations of sanitary landfill leachate, considering the feasibility of its use as source of nutrients for agricultural production. Biometric and vigor variables were analyzed through the measurements of collar diameter, shoot height, number of leaves and shoot and root fresh and dry matters, from January to February 2015. The experimental design was completely randomized in a 5 x 4 factorial scheme: five leachate concentrations (0, 40, 60, 80 and 100 kg N ha-1) x four harvest periods (14, 21, 25 and 29 days after sowing), with five replicates each containing two plants. The data were subjected to analysis of variance and polynomial regression, and... |

| Com este trabalho objetivou-se avaliar o crescimento, a nutrição e a produção da bananeira Prata Anã (Musa spp), consorciada com leguminosas e submetida a diferentes lâminas de irrigação. O delineamento experimental utilizado foi em blocos casualizados em parcelas subdivididas, com cinco repetições. As parcelas foram formadas por quatro lâminas de irrigação: 50, 75, 100 e 125% da evapotranspiração da cultura (ETc) e as subparcelas pela testemunha (manejo convencional sem plantas de cobertura) e três tipos de plantas de cobertura consorciadas com a bananeira, são elas: vegetação espontânea (VE), cudzu tropical em sucessão à crotalária (CK) e calopogônio em sucessão ao feijão-de-porco (FC). Avaliaram-se, nas plantas de bananeira, a altura, a circunferência... |
