2. Canopy structure and forage nutritive value of elephantgrass subjected to different stocking rate and N fertilization in the “Mata Seca” ecoregion of Pernambuco
ABSTRACT The objective was to evaluate the effect of three stocking rates (2, 3.9, and 5.8 animal units ha−1) and three fertilization levels (0, 150, and 300 kg N ha−1 yr−1) on herbage mass and nutritive value of elephantgrass (Pennisetum purpureum Schum.) cv. IRI-381. The experiment was conducted from May to August of 2009 and 2010 in Itambé, PE, Bra

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. Effects of ensiling density on nutritive value of maize and sorghum silages
ABSTRACT Studies were conducted to determine the effects of different ensiling densities on fermentation, aerobic stability, and nutritive value of maize and sorghum silages. Maize and sorghum were harvested at dough (363 g/kg) and milk stages (275 g/kg), respectively. Herbages were chopped approximately 1.5 cm after harvest and then ensiled in mini silos at

6. DINÂMICA DO FÓSFORO EM ECOSSISTEMA DE PASTAGEM NATURAL SUBMETIDO À APLICAÇÃO DE FONTES DE FOSFATO / PHOSPHORUS DYNAMICS IN NATURAL GRASSLAND ECOSYSTEM SUBMITTED TO APPLICATION OF PHOSPHATE SOURCES
O conhecimento da dinâmica do fósforo nos ecossistemas campestres pode ser importante para a prescrição das alterações provocadas pela adição de diferentes fontes de fertilizantes fosfatados sobre as formas de P no solo, na produção de matéria seca e na composição botânica das pastagens naturais. O objetivo do presente trabalho foi avaliar a in

7. Forage yield and nitrogen nutrition dynamics of warm-season native forage genotypes under two shading levels and in full sunlight
The successful achievement of a highly productive understorey pasture in silvopastoral systems depends on the use of well-adapted forage genotypes, showing good agronomic performance and persistence under shading and grazing. In this study, the herbage dry matter yield (DMY) and nitrogen nutrition dynamics were determined in three native warm-season grasses

8. Biomass components in Massai grass during establishment and regrowth under five nitrogen fertilization levels
To evaluate biomass components of Massai grass under five doses of N (0, 150, 300, 450 and 600 mg N/dm³ soil) during three cycles of growth (establishment, regrowth 1 and regrowth 2) this study was carried out. The experiment was carried out in a greenhouse, in a completely randomized design with measures repeted over time and five replications. In the thre

9. 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

10. Consumo e utilização de nutrientes por ovinos em pastagem de azevém anual / Intake and nutrient utilization in sheep fed with italian ryegrass
Levels of forage supply for sheep fed with Italian Ryegrass (Lolium multiflorum Lam.) were studied. Trials were carried out in metabolic cages, offering levels (1.5, 2, 2.5% of live weight of dry matter and ad libitum) at three plant phenological stages (vegetative, pre-flowering and flowering). With the data of these trials, equations were generated to esti

11. 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
