| O feijoeiro comum, pertencente à classe Dicotiledoneae, família Fabaceae, subfamília Papilionoidae, gênero Phaseolus e espécie Phaseolus vulgaris L., é a espécie mais cultivada do gênero Phaseolus e representa uma importante fonte de proteína e energia para a alimentação humana, em especial nos países onde o consumo de proteína animal é limitado, por razões econômicas ou religiosas e culturais, muito embora já tenha sido considerado de baixo valor nutritivo. No Brasil, esta leguminosa apresenta importância social e econômica, por ser responsável pelo suprimento de grande parte das necessidades alimentares da população de baixo poder aquisitivo. |

| Árvores de taxi (Sclerolobium paniculatum, Vogel) cultivadas no Campo Experimental de Belterra, PA, com idades de 12, 24, 60, 72, 108 e 180 meses foram abati- das, separando-se seus componentes (folhas, ramos e fuste) que foram pesados e analisados quimicamente com o objetivo de verificar a produção de distribuição da biomassa, concentração, distribuição e conteúdo de nutrientes na planta. A biomassa aumentou com o aumento da idade da planta, devido a elevação do volume do fuste, ocorrendo uma estabilização dos demais componentes até o nono ano. A concentração dos macronutrientes nos tecidos dos vários componentes da árvore tenderam a decrescer com a idade dos povoamentos. As maiores concentrações de nutrientes ocorreram nas folhas, seguido de ramos e... |

| This study was conducted in order to evaluate the association of phytase with an enzymatic complex comprised of carbohydrases (α-galactosidase, galactomannan, xylanase and β-glucanase) in nutrition reduction diets for semi-heavy laying hens and its effect on egg performance and egg quality. Four hundred Isa Brown laying hens with 42 to 57 weeks of age were distributed in an entirely random experiment with five treatments and 8 repetitions, during five production periods of 21 days. Variables studied: egg production, feed intake, mean egg weight, feed conversion, Haugh unit, percentage of yolk, egg white and albumen, yolk color, eggshell thickness and specific gravity. There was a significant interaction (p < 0.05) between treatments and experimental... |

| ABSTRACT: Chemical and physical properties of soil can be altered with the successive application of liquid swine manure (LSM), also known as slurry. Therefore, monitoring the impact of LSM is essential to an assessment of the potential agronomic and environmental benefits and risks associated with management practices. The aim of this study was to evaluate the effects of LSM on the chemical and physical attributes of soil under pasture (Cynodon spp.), located in southern Brazil. Four areas were sampled: three areas cultivated with Cynodon spp. pasture with successive applications of 200 m3 ha–1 y–1 of LSM for three, eight and 15 years; and untreated native forest as a reference. The soil attributes evaluated were: organic carbon (OC), active (pH water)... |

| Foliar pathogens face heterogeneous environments depending on the maturity of leaves they interact with. In particular, nutrient availability as well as defense levels may vary significantly, with opposing effects on the success of infection. The present study tested which of these factors have a dominant effect on the pathogen’s development. Poplar leaf disks of eight maturity levels were inoculated with the poplar rust fungus Melampsora larici-populina using an innovative single-spore inoculation procedure. A set of quantitative fungal traits (infection efficiency, latent period, uredinia size, mycelium quantity, sporulation rate, sporulation capacity, and spore volume) was measured on each infected leaf disk. Uninfected parts of the leaves were analyzed... |

| ABSTRACT - The objective of this work was to evaluate the nutrient availability for corn (Zea mays) grown successively in pure and ground biotite schist and biotite syenite rock samples. The rock powders were subjected to chemical, physical, and mineralogical characterization, and the availability of the elements released to the plants was determined. Plant and rock materials were evaluated at the end of seven successive growth cycles. Biotite schist and biotite syenite provided nutrients - as K, Ca, Mg, Fe, and Mn - to the corn plants. The nutrients accumulated in plant tissues came mostly from minerals containing oxidizable Fe and Mn in their structure, such as biotite, chlorite, and clinopyroxene. The congruent dissolution of some of the fine particles... |

| The current high price of potassium chloride and the dependence of Brazil on imported materials to supply the domestic demand call for studies evaluating the efficiency of alternative sources of nutrients. The aim of this work was to evaluate the effect of silicate rock powder and a manganese mining by-product, and secondary materials originated from these two materials, on soil chemical properties and on brachiaria production. This greenhouse experiment was conducted in pots with 5 kg of soil (Latossolo Vermelho-Amarelo distrófico - Oxisol). The alternative nutrient sources were: verdete, verdete treated with NH4OH, phonolite, ultramafic rock, mining waste and the proportion of 75 % of these K fertilizers and 25 % lime. Mixtures containing 25 % of lime... |

| Abstract: The objective of this work was to evaluate changes in the soil chemical properties, nitrogen use efficiency, and grain yield of flood-irrigated rice fields after the addition of poultry manure during five years. Trials were carried out in a randomized complete block design, with three replicates. The treatments were: chemical fertilizers, N-P2O5-K2O; control, no fertilizers; and poultry manure doses, 2.5, 5.0, and 10.0 Mg ha-1. Poultry manure increased soil pH, base saturation, and phosphorus, potassium, calcium, and zinc contents more than the chemical fertilizers. Adding poultry manure to the soil increased N ammonification (35 mg kg-1 NH4 +-N) from the first to the fourth week after rice was sown. The exclusive use of poultry manure was not... |
