| ABSTRACT Caygua fruits (Cyclanthera pedata) are used both in cooking and for medicinal purposes. However, few studies on this species, considered a non-conventional vegetable, can be found in literature. This study aimed to assess the responses of caygua crop to green manure and mineral nitrogen fertilization, in relation to marketable fruit productivity, nutrient content in leaves and fruits and bromatological composition. The study was carried out in a randomized block design with four treatments and five replicates: 1) control (without nitrogen); 2) 60 kg ha-1 nitrogen (urea form); 3) green manuring using Cajanus cajans and 4) green manuring using Crotalaria juncea. The plots consisted of three caygua lines with four plants per line (spacing 2x1 m). In... |

| Highly weathered tropical soils are characterized by having a predominantly variable charge. Many management practices commonly used in the exploitation of these soils (e.g.,liming, phosphate application, and manuring) are known to modify their electrical charge and the sorption/desorption behavior of cations and anions. This process is, at least, partially governed by the charges existing in the soil system. Available information on this subject comes mainly from short-term laboratory and greenhouse experiments. There is a lack of data regarding the cumulative and long-term effects of those practices used at farm-scale levels and on the dynamics and availability of nutrients to the plants under field conditions. In the present work, changes in some... |

| ABSTRACT: The cultivation and deposition of cover crops residues on the soil surface can reduce weed emergence. The objective of this study was to evaluate the emergence of weeds, in a greenhouse, on a soil with cover crops in an agroecological no-tillage system. The experiment was conducted in a greenhouse with soil samples from an experiment installed in Ituporanga (Santa Catarina state). On April 2010 and 2011, the following field treatments were implemented: weed vegetation (VE), Hordeum vulgare (2010)/Avena strigosa (2011) (CV/AV), Secale cereale (CE), Raphanus sativus (NF), Secale cereale + Raphanus sativus (NF+CE) and Hordeum vulgare/Avena strigosa + Raphanus sativus (NF+AV). After the rotation of the species, the soil samples were collected in... |

| The effects of organic fertilization combining cattle manure and pigeon pea shoots on the culture of rocket, planted with one or two plants per hole, including soil microbial biomass carbon, soil respiration, the metabolic quotient, soil fumigation labile carbon, and the dry matter content and total N, K, P, Ca and Mg contents in the leaves and roots of rocket were investigated. The experimental design was randomized blocks in a 2 × 2 × 2 factorial experiment: 0 and 160 kg ha-1 N from cattle manure, 0 and 160 kg ha-1 N from pigeon pea shoots, and one or two plants per hole, with three replicates. The most significant and positive correlations were obtained between leaf K × soil respiration, microbial biomass × leaf N and root Ca × metabolic quotient. The... |

| O consórcio entre gramíneas e leguminosas para produção de palha, no sistema plantio direto, visa conciliar a proteção do solo, por meio da maior durabilidade da gramínea, com a fixação de N e disponibilização mais rápida de nutrientes pela decomposição da leguminosa. Diante disso, instalou-se um experimento para determinar a produção de fitomassa e o teor e acúmulo de micronutrientes do milheto, feijão-de-porco e guandu-anão, em cultivo solteiro e nos consórcios da gramínea com as leguminosas, para a produção de palha no plantio direto. O trabalho foi conduzido no campo experimental do Departamento de Agricultura da Universidade Federal de Lavras – Lavras, Estado de Minas Gerais. O delineamento foi o de blocos casualizados, com sete tratamentos, para os... |

| O objetivo deste estudo foi verificar a influência do manejo agroecológico na distribuição dos agregados estáveis em água e no teor de carbono orgânico dos agregados em diferentes coberturas vegetais. Foram selecionadas cinco áreas, a saber: sistema agroflorestal; cultivo de figo (Ficus carica L.); consórcio maracujá (Passiflora edulis S.)–Desmodium sp.; cultivo de feijão (Phaseolus vulgaris L.), em manejo convencional, e cultivo de milho (Zea mays L.), em plantio direto. Em cada área, foram coletadas amostras de terra indeformadas, nas profundidades de 0 - 5 e 5 - 10 cm, e avaliada a estabilidade dos agregados e o teor de carbono orgânico nos agregados (COAGR). A maior massa de agregados encontra-se na classe de 2,00 mm, em ambas as profundidades, com... |
