| ABSTRACT: Global support for Conservation Agriculture (CA) as a pathway to Sustainable Intensification is strong. CA revolves around three principles: no-till (or minimal soil disturbance), soil cover, and crop rotation. The benefits arising from the ease of crop management, energy/cost/time savings, and soil and water conservation led to widespread adoption of CA, particularly on large farms in the Americas and Australia, where farmers harness the tools of modern science: highly-sophisticated machines, potent agrochemicals, and biotechnology. Over the past 10 years CA has been promoted among smallholder farmers in the (sub-) tropics, often with disappointing results. Growing evidence challenges the claims that CA increases crop yields and builds-up soil... |

| To determine the chemical composition of intercropping and monoculture cultivars of sorghum, millet and midget-guandu, we determined the production of dry matter (DM), ashes, gross fiber, ethereal extract, gross protein (GP), nutritious digestive total, and extractive without oxygen. The experimental design used was completely random blocks with four repetitions split into 18 treatments: monoculture sorghum, monoculture midget-guandu, monoculture millet, intercropping sorghum and midget-guandu, millet and midget-guandu and millet and sorghum, with cutting times at 30, 60 and 90 days after sowing (DAS). Millet had the highest production of dry biomass at 30 and 60 DAS in monoculture and intercropping. The highest DM was obtained by intercropping (90 DAS).... |

| The soluble and insoluble cotyledon (SPF-Co and IPF-Co) and tegument (SPF-Te and IPF-Te) cell wall polymer fractions of common beans (Phaseolus vulgaris) were isolated using a chemical-enzymatic method. The sugar composition showed that SPF-Co was constituted of 38.6% arabinose, 23.4% uronic acids, 12.7% galactose, 11.2% xylose, 6.4% mannose and 6.1% glucose, probably derived from slightly branched and weakly bound polymers. The IPF-Co was fractionated with chelating agent (CDTA) and with increasing concentrations of NaOH. The bulk of the cell wall polymers (29.4%) were extracted with 4.0M NaOH and this fraction contained mainly arabinose (55.0%), uronic acid (18.9%), glucose (10.7%), xylose (10.3%) and galactose (3.4%). About 8.7% and 10.6% of the... |

| In this experiment the chlorophyll and carbohydrate contents of Arachis pintoi were evaluated to verify if the presence of nitrogen in the soil could contribute to the effectiveness of the establishment of this legume. The design was completely randomized, in a 4 × 4 factorial arrangement, with four N rates (0, 40, 80 and 120 kg ha-1) and four irrigation levels (25, 50, 75 and 100% of field capacity), with four replications. The biochemical evaluations of chlorophylls a and b and total chlorophyll and total soluble sugars, sucrose and starch were performed. The highest contents of chlorophyll a and b and total chlorophyll in leaves were found at the dose of 120 kg ha-1. The water regime of 25% of field capacity was responsible for the lowest content of... |

| Abstract: The objective of this work was to compare three methods of 15N isotope application to the soil in order to determine the recovery efficiency of nitrogen derived from green manure by corn (Zea mays). The used experimental design was a randomized complete block with six replicates. The treatments consisted of three 15N isotope methods: indirect method I, isotope dilution with 15N-labelled synthetic fertilizer applied through a small hole next to each corn plant; indirect method II, isotope dilution with 15N-labelled synthetic fertilizer spread in the furrow next to the corn planting row; and direct method, application of a legume straw as green manure, treated with 2.23% excess 15N. The green manure used was jack bean (Canavalia ensiformis).... |

| Objetivou-se avaliar a composição química e as perdas totais de MS na silagem de soja colhida em diferentes estádios reprodutivos. O trabalho foi dividido em dois períodos experimentais, safras de 2005 e de 2006. Foram determinados quatro estádios reprodutivos (R3, R4, R5 e R6) como tratamento no Experimento I (2005) e três estádios reprodutivos (R5, R6 e R7) no Experimento II (2006). O material foi acondicionado em silos experimentais de PVC, sendo as amostragens efetuadas na abertura do silo (60 dias após a ensilagem) para avaliar a composição química. No Experimento I, houve diferenças (p < 0,05) nos quatro estádios reprodutivos para os teores de MS, CZ, MO, PB, LIG, EE e CT. Não se verificou diferença (p > 0,05) para os valores de FDN, FDA,... |

| O presente trabalho objetivou avaliar o efeito de fungos micorrízicos arbusculares (FMAs) no crescimento de mudas de acácia (Acacia mangium Willd.), sesbânia (Sesbania virgata (Cav.) Pers.) e eucalipto (Eucalyptus camaldulensis Dehnh.) em casa-de-vegetação e o comportamento dessas espécies, inoculadas ou não com FMAs, em monocultivo e/ou consórcio em áreas degradadas pela extração de argila. Aos 75 dias após a semeadura (DAS), mudas de acácia e sesbânia, inoculadas com FMAs, apresentaram incrementos de 21,5 e 6,5% na altura, respectivamente, em relação às não-inoculadas. Semelhantemente o acúmulo de matéria seca na parte aérea de acácia e sesbânia com FMAs foi de 50 e 52%, respectivamente, em relação às não-inoculadas. Na cava-de-extração de argila, as... |
