Description
The response of grassland production (herbage mass) to factors limiting its production, can be considered the collective response of a number of components. Understanding the impact of factors limiting individual components will aid understanding of factors limiting total production. Pre-requisite to such an analysis is quantification of the contribution of each component to herbage mass. Perhaps even more important are the dynamics (rate of change with time) of these components and their response to factors such as water stress.
The objectives of this study were : 1) to assess the importance of seven components to herbage mass using principle component analysis. 2) to quantify the response of the most important components to water stress.
