Piata palisadegrass deferred in the fall: effects of initial height and nitrogen in the sward structure [PDF]

Revista Brasileira de Zootecnia, 2012
The objective of this study was to evaluate the mass of the forage and of the morphological components, and the sward structure in Piata palisadegrass (Brachiaria brizantha cv. Piata) deferred in function of different initial heights and nitrogen levels.

Optimising sward structure and herbage yield for the performance of dairy cows at pasture. [PDF]

, 1999
End of Project Reports The basic unit of intake is the bite. The total daily intake of grazed grass is determined by the number of bites taken and the weight of the average bite. In this project the focus was on sward structure (architecture) and its effects on bite volume and weight. There were two objectives.

Changes in sward structure, plant morphology and growth of perennial ryegrass–white clover swards over winter

Irish Journal of Agricultural and Food Research, 2021
White clover (Trifolium repens L.) is at a disadvantage to perennial ryegrass (Lolium perenne L.; PRG) due to its limited cold tolerance and low growth rates at colder temperatures, which can affect subsequent spring herbage dry matter (DM) availability.

The impact of tourist traffic on the condition and cell structures of alpine swards [PDF]

Remote Sensing, 2017
This research focuses on the effect of trampling on vegetation in high-mountain ecosystems through the electromagnetic spectrum’s interaction with plant pigments, cell structure, water content and other substances that have a direct impact on leaf properties.

The Usefulness of Mixtures with Festulolium braunii for the Regeneration of Grassland under Progressive Climate Change

Agriculture, 2021
The climate warming and changes in weather patterns in Europe are negatively affecting the structure of grassland swards. The disappearance of valuable forage grasses can be observed. Therefore, in order to keep grassland productivity high, high-yielding

Sward structural resistance and biting effort in grazing ruminants [PDF]

Animal Research, 2003
Grazing ruminants face complex decisions in searching for and harvesting adequate forage to meet their requirements in the face of heterogeneity in the abundance, nutritive value and distribution of resources. Some of the major decisions which affect the bite mass and therefore, forage intake adjustments in bite depth, bite area and exerted bite force,

Influence of agricultural management, sward structure and food resources on grassland field use by birds in lowland England. [PDF]

, 2005
Agricultural management of grassland in lowland Britain has changed fundamentally in the last 50 years, resulting in spatial and structural uniformity within the pastoral landscape.

Tillering and forage accumulation in Marandu grass under different grazing intensities

Revista Ceres, 2011
Studies of plant responses to defoliation are important to develop pasture management strategies. The objective of this study was to evaluate the population density of basal, aerial and reproductive tillers, tiller appearance and mortality rates, forage ...

The use of frequency estimates in studying sward structure

Grass and Forage Science, 1992
AbstractEstimates of the frequency of absence of rooted perennial ryegrass tiller bases from concentric sampling quadrats of different sizes are recommended for characterizing the open space structure of perennial ryegrass swards. It is proposed that these estimates are useful for evaluating the persistence of grass species and cultivars in swards ...
