1. Structural characteristics and forage mass of Tifton 85 pastures managed under three post-grazing residual leaf areas
The experiment was carried out on Cynodon spp cv. Tifton 85 pastures grazed by sheep under rotational stocking, with the objective of evaluating the structural characteristics as well as the forage mass of the pastures subjected to three grazing intensities in successive cycles. Treatments were composed of three residual leaf area indices (rLAI; 2.4; 1.6 and

2. Tillering dynamics in Guinea grass pastures subjected to management strategies under rotational grazing
This study was carried out to analyze the tillering profile of Guinea grass (Panicum maximum cv. Tanzania) pastures subjected to two grazing frequencies (time necessary to intercept 90 and 95% of the incoming light) and two post-grazing heights (30 and 50 cm) in the period from November 2005 to October 2006. The experimental design was of completely randomiz

3. IPR 126 white oat forage potential under free growth, cutting and grazing at two management heights
The experiment was carried out to evaluate the structural characteristics, biomass accumulation, chemical composition and in vitro digestibility of dry matter and crude protein of white oat (Avena sativa L. IPR 126) under different management systems. Grazing, cut at two heights (15 and 20 cm) and free growth were all evaluated in three periods (July, August

4. Densidade populacional e dinâmica do perfilhamento em capim-marandu submetido a estratégias de pastejo rotativo e adubação nitrogenada / Tiller population density and tillering dynamics in marandu palisade grass subjected to strategies of rotational stocking management and nitrogen fertilisation
O perfilhamento é aspecto central da produtividade e perenidade de plantas forrageiras em pastagens, porém normalmente avaliado sob escalas reduzidas de experimentação (parcelas e piquetes). O objetivo deste experimento foi avaliar a densidade populacional de perfilhos e a dinâmica do perfilhamento em capim-marandu submetido a estratégias de pastejo ro

5. Rebrotação na primavera de pastos de capim-braquiária diferidos em quatro alturas / Regrowth in the spring of the Brachiaria decumbens pasture deferment four pasture heights
Durante abril a dezembro de 2009, o experimento deste estudo foi conduzido em pastagem de Brachiaria decumbens cv. Basilisk (capim-braquiária) pertencente ao Setor de Forragicultura do Departamento de Zootecnia da Universidade Federal de Viçosa, com o objetivo de avaliar os efeitos das alturas dos pastos no início do diferimento e a sua utilização duran

6. Densidade populacional, padrões demográficos e dinâmica da população de perfilhos em pastos de capim-marandu submetidos a lotação contínua e ritmos de crescimento contrastantes / Tiller population density, demographic patterns of tillering and tiller population dynamics on continuously stocked marandu palisadegrass subjected to contrasting rhythms of growth
Tillering is a growth strategy that forage grasses developed during their coevolution with herbivores as a means of ensuring survival, perennation and productivity, which is strongly influenced by several environmental and management factors. Recent studies, focusing on tillering of tropical grasses, have contributed to the understanding of plant responses t

7. Demografia do perfilhamento e produção de forragem em pastos de capim-marandu submetidos a regimes de lotação intermitente por bovinos de corte / Tiller demography, tillering dynamics and growth of marandu palisadegrass swards subjected to strategies of rotational stocking
Tillering plays a central role in the recovery of sward leaf area and growth patterns of forage plants, influencing pasture longevity and productivity. However, little is known about the tillering process in tropical grasses, particularly Brachiaria brizantha cv. Marandu (marandu palisadegrass), one of the most used species on cultivated grassland areas in B

8. Caracterização morfogênica de gramíneas forrageiras tropicais sob crescimento livre / Morphogenetic charaterization of tropical forage grasses under free growth
In this work, the morphogenetic and structural characteristics of tropical grasses were evaluated in a comparative way, aiming their insertion in the respective functional groups, supplying subsidies to researchers in the implementation of grazing experiments suitable with their growth pattern and development. The experiment was conducted in the Forage Cultu

9. Morphogenesis, tillering and herbage accumulation dynamics in marandu grass swards under continuous stocking. / Morfogênese, dinâmica do perfilhamento e do acúmulo de forragem em pastos de capim-marandu sob lotação contínua.
Brazil is a unique environment for developing efficient and sustainable pastoral systems of animal production. Advances in this area have been modest however, resulting in slow progress and revealing deficiencies of the current conceptual basis used for interpreting results from research, particularly those related to the dynamic and systemic characteristic
