1. Beef cattle performance on signal grass pastures deferred and fertilized with nitrogen
RESUMO Foi avaliado o efeito de quatro doses de nitrogênio (0, 40, 80 e 120kg N ha -1 ), aplicadas antes do diferimento, sobre o desempenho de bovinos e as características estruturais de Urochloa decumbens (capim-braquiária), de janeiro a outubro de 2012 e de janeiro a setembro de 2013. Um delineamento de blocos ao acaso foi utilizado em arranjo de medid

2. Productivity and nutritive value of elephant grass pastures under organic and conventional production systems
Abstract: Elephant grass (EG) (Pennisetum purpureum Schum.) have great importance in tropical and subtropical climates, especially on dairy farms. Normally, EG is established alone under high fertilization levels. EG in organic production system can improve low production costs and environmental issues, are still little known. The aim of this research was to

3. Wilting whole crop black oat with glyphosate for ensiling: effects on nutritive, fermentative, and aerobic stability characteristics
ABSTRACT We aimed to evaluate the effects of glyphosate as a chemical desiccant on the nutritional quality, fermentation pattern, and aerobic stability of wilted black oat (Avena strigosa Schreb) silage. Black oat sowing occurred in the first fortnight of May 2013. Desiccant application took place when oat reached milky/dough grain stage (96 days after plant

4. Evaluation of blood metabolites in dairy cows grazing under two pasture allowances and supplemented with corn silage under restricted grazing conditions
ABSTRACT This study was conducted to evaluate the influence of management tools - daily pasture allowance and corn silage supplementation - during periods of forage shortage on the metabolism of dairy cows grazing low-mass pasture in temperate regions. Forty lactating Holstein cows were used during an experimental period of seventy days (April 15 to June 23,

5. Microbial quality of soil from the Pampa biome in response to different grazing pressures
The aim of this study was to evaluate the impact of different grazing pressures on the activity and diversity of soil bacteria. We performed a long-term experiment in Eldorado do Sul, southern Brazil, that assessed three levels of grazing pressure: high pressure (HP), with 4% herbage allowance (HA), moderate pressure (MP), with 12% HA, and low pressure (LP),

6. Herbage utilisation efficiency of continuously stocked marandu palisade grass subjected to nitrogen fertilisation
Nitrogen fertiliser accelerates plant growth and increases herbage utilisation efficiency in continuously stocked temperate grass swards, indicating greater herbage production and harvest efficiency. There is no similar evidence, however, for tropical pastures. In this study we evaluated the morphogenetic responses, the patterns of defoliation and the effici

7. Herbage accumulation and grazing losses on Mulato grass subjected to strategies of rotational stocking management
Grazing management strategies affect not only herbage accumulation but also the efficiency of grazing. This study aimed to evaluate herbage accumulation (leaf, stem and dead material), grazing efficiency and losses of mulato grass (a Brachiaria ruziziensis × Brachiaria brizantha cv. Marandu hybrid) subjected to strategies of rotational stocking management.

8. Biomass flow in massai grass fertilized with nitrogen under intermittent stocking grazing with sheep
This study evaluated the biomass flow of massai grass in regrowth subjected to different nitrogen levels (control - no fertilization; 400; 800; and 1200 N kg ha-1year-1) and under rotational stocking with sheep, in a completely randomized design with repeated measures over time. The leaf elongation rate increased with increasing nitrogen levels (N) and the f

9. ESTUDO DA RECRIA DE NOVILHAS DE CORTE EM PASTAGENS CULTIVADAS DE VERÃO / STUDY OF BEEF HEIFERS REARING ON WARM-SEASON PASTURES
Heifers rearing is a determinant step of efficiency in beef cattle production systems on pastures. Several experiments have tested alternative uses for tropical grasses to heifers rearing. In order to summarize results and making not visible relationships evident in these individual experiments an analysis was performed in a set of data from six experiments

10. Banco de sementes e sistemas de renovação no pasto de capim-braquiária com integração de culturas agrícolas / Seed bank in renewal of pasture signal grass with crop livestock integration
The experiment was conducted to evaluate the renewal of pasture of Brachiaria decumbens with integration of crops in cropping systems "planting" direct and conventional. The experiment was conducted in pastures of Brachiaria decumbens Stapf. Located on the campus of University Federal of Viçosa, Viçosa, MG. The experiment consisted of five "systems" of gra

11. Development of maize and palisadegrass plants cultivated in intercrop under water deficit
The objective of this work was to evaluate the development and productive traits of palisadegrass single cultivated or intercropped with corn, in addition to corn intercropped with pasture, under water deficit at different development stages of the plants. It was used a complete block experimental design with split plots and three replicates. Periods of wate

12. Produtividade do capim Marandu sob diferentes tensões hídricas no solo e doses de nitrogênio.
RESUMO: Este experimento foi conduzido na Embrapa Cerrados, Planaltina (DF), no período de março de 2000 a janeiro de 2001, em um Latossolo Vermelho-Escuro, textura argilosa. O objetivo foi o de avaliar o efeito de tensões de água no solo (35, 60, 100 e 500 kPa) e doses de nitrogênio (0, 30, 60, 120 kg/ha de N), exceto no primerio corte (0, 15, 30 e 60
