| It is estimated that 60% of the area of cultivated pasture, in the Brazilian Savannah, is degraded or in process of degradation, due to, among other causes, the lack of nitrogen. The Stylosanthes genus is the legume which has the greater number of cultivars used in tropical pastures, however, its seeds have characteristics which can difficult the formation of an adequate stand of plants on pasture. In this research the aim was to evaluate the effects of priming in the speed and uniformity of the Stylosanthes capitata, S. macrocephala and S. guianensis seeds germination. The seeds were kept for 12, 24, 36 and 48 hours in aired media PEG 6,000 at 0.0, -0.5, -1.0 and -1.5MPa. Afterwards, they were sent to the germination test. The variables analyzed were... |

| This study was carried out to evaluate the productivity and utilization efficiency of a mixed marandugrass (Brachiaria brizantha cv. Marandu), forage peanut (Arachis pintoi cv. Mandobi) and tropical kudzu (Pueraria phaseoloides) pasture, rotationally stocked at four daily forage allowance levels (6.6, 10.3, 14.3 and 17.9% of live weight), in order to define sward management targets for these mixtures. In each stocking cycle, dry matter (DM) accumulation rates, defoliation intensity (%), grazing depth (%) and grazed horizon (cm) were evaluated. Sward targets were defined according to the sward condition that best conciliated the grass-legume balance and the equilibrium between forage production and utilization. Pastures submitted to higher forage allowance... |

| This study was carried out from October 2002 to December 2003 to evaluate the dynamics of sward condition and botanical composition of a mixed massaigrass (Panicum maximum x P. infestum, cv. Massai) and forage peanut (Arachis pintoi Ac 01) pasture, intermittently stocked at three daily herbage allowance levels (9.0, 14.5 and 18.4% live weight). Sward condition was characterized in each grazing cycle in terms of the pre and post-grazing sward height, forage mass and percentage of bare ground. Botanical composition (grass, legume and weeds) was evaluated before each grazing period. Sward height and forage mass increased linearly with increasing herbage allowance (HA) levels, and higher values were observed during the rainy season. Percentage of bare ground... |

Sward condition was characterized in each stocking cycle by measuring pre- and post-grazing sward height, forage mass and percentage of bare ground. Botanical composition (grass, forage peanut, tropical kudzu and weeds) was evaluated before each stocking period. Swards under smaller forage allowances presented lower height, forage mass and ground cover. This condition favored the growth of forage peanut,... |

| This study was carried out to evaluate the productivity, utilization and sward structure of a mixed massaigrass (Panicum maximum x P. infestum, cv. Massai) and forage peanut (Arachis pintoi Ac 01) pasture, intermittently stocked at three daily herbage allowance levels (9.0, 14.5 and 18.4% of live weight). In each grazing cycle, dry matter (DM) accumulation rates, defoliation intensity (%), grazing depth (%) and grazed horizon (cm) were evaluated. The structure of massaigrass tussocks was characterized in both dry and rainy seasons by measuring its pre-grazing morphological composition and post-grazing height and density (tussocks/m). Pastures submitted to higher herbage allowance (HA) levels showed higher productivity, but were less efficiently utilized.... |

| La fermentación y metanogénesis ruminal son procesos metabolicos vitales para los bovinos y son llevados a cabo por poblaciones microbianas, las cuales se afectan por factores como la presencia de metabolitos secundarios, la composición nutricional y la degradabilidad de la dieta. El objetivo de este trabajo fue monitorear las poblaciones de bacterias totales, metanógenos totales y Butirivibrio fibrisolvens en el rumen de novillas raza Lucerna, alimentadas con dietas típicas de un sistema silvopastoril intensivo y un sistema tradicional. Para ello, se colectó contenido ruminal (CR) por vía oral a ocho novillas que consumían 100% Cynodon plectostachyus (control) y 76% C. plectostachyus + 24% Leucaena leucocephala siguiendo un diseño de sobre-cambio.

| 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).... |

| Leguminous winter cover crops have been utilized in conservation systems to partially meet nitrogen (N) requirements of succeeding summer cash crops, but the potential of summer legumes to reduce N requirements of a winter annual grass, used as a cover crop, has not been extensively examined. This study assessed the N contribution of peanut (Arachis hypogaea L.) residues to a subsequent rye (Secale cereale L.) cover crop grown in a conservation system on a Dothan sandy loam (fine-loamy, kaolinitic, thermic Plinthic Kandiudults) at Headland, AL USA during the 2003-2005 growing seasons. Treatments were arranged in a split plot design, with main plots of peanut residue retained or removed from the soil surface, and subplots as N application rates (0, 34, 67... |

| 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,... |
