Grazing strategies alter sward leaf area patterns of growth, affecting herbage accumulation and utilisation. The objective this experiment was to evaluate the growth marandu palisadegrass (Brachiaria brizantha cv. Marandu) swards subjected intermittent stocking. carried out in Piracicaba, São Paulo, Brazil, from October/2004 September/2005. Swards were grazed at 95 100% canopy light interception (LI) post-grazing heights 10 15 cm, following a 2 × factorial arrangement with four replications...
Knowledge regarding morphogenetic characteristics has contributed to the understanding of plant responses variations in climatic conditions and management practices. However, original framework been developed for temperate grass species, indicates no ontogenetic effect on expression traits. Similar information tropical species is scarce, but not less important. This experiment aimed at evaluating influence tiller age continuously stocked marandu palisadegrass swards maintained 30 cm...
The objective of this experiment was to evaluate the structural characteristics young, mature and old tillers on continuously stocked marandu palisade grass maintained at 30 cm fertilized with nitrogen. Treatments corresponded three nitrogen application rates (150, 300 450 kg/ha N) plus control (no fertilization) were assigned experimental units (1,200-m² paddocks) according a completely randomized block design, four replications. Measurements performed during fall/winter 2007 summer 2008....
O objetivo deste trabalho foi avaliar a sobrevivência e estabilidade da população de perfilhos em pastos capim-marandu (Brachiaria brizantha) submetidos à lotação contínua adubação nitrogenada. Os tratamentos corresponderam três doses nitrogênio (150, 300 450 kg ha-1) mais o controle (sem adubação), as unidades experimentais (piquetes 1.200 m²) foram dispostas segundo um delineamento blocos completos ao acaso, com quatro repetições. Foram avaliados mensalmente taxas sobrevivência, balanço...
Leaf area index is the main sward characteristic related to processes of light interception and competition in plant communities. The objective this experiment was quantify evaluate composition leaf on tillers marandu palisadegrass (Brachiaria brizantha cv. Marandu) subjected strategies intermittent stocking. carried out Piracicaba, state São Paulo, Brazil, from October/2004 December/2005. Swards were grazed at 95 100% canopy (LI) post-grazing heights 10 15 cm, following a 2 ' factorial...
Nitrogen fertiliser accelerates plant growth and increases herbage utilisation efficiency in continuously stocked temperate grass swards, indicating greater production harvest efficiency. There is no similar evidence, however, for tropical pastures. In this study we evaluated the morphogenetic responses, patterns of defoliation marandu palisade (Brachiaria brizantha (Hochst. ex A. Rich.) Stapf. cv. Marandu) maintained at 30 cm by cattle fertilised with nitrogen. Treatments corresponded to...
Acceleration of the growth rhythm plants using nitrogen fertiliser alters rates physiological processes like and senescence may cause significant changes in sward structure, interfering with plant animal responses. The objective this experiment was to evaluate structure marandu palisadegrass (Brachiaria brizantha) maintained at 30 cm under continuous stocking subjected contrasting rhythms from January 2007 April 2008. These were generated or not fertiliser, comprised four experimental...
The concept of sward target has been used recently to characterise grazing management practices, but its efficiency monitor and control structure questioned since it corresponds a single structural feature, usually surface height. objective this experiment was evaluate patterns variation throughout the year on continuously stocked marandu palisadegrass swards maintained at 30 cm subjected contrasting rhythms growth from January 2007 April 2008. Treatments corresponded three nitrogen...
A few decades ago we sought the understanding of functioning Brazilian ecosystems. During these years, changes in way land use were influenced primarily by economic issues involving process valuation different regions. Furthermore, developments research have provided productive increments that well characterized some phases. This paper aims to trace a brief history distribution grassland ecosystems Brazil and show how it has been advances on forages pastures country, pointing its evolution,...
