Studying the effect of variable temperature and CO2 air enrichment on changes in the nutritive value of orchard grass (Dactylis glomerata L.) in permanent grassland
Abstract
The main objective of this study is to investigate the impact of elevating temperature and CO2 air concentration on the nutritive value of Dactylis glomerata L. growing in permanent grassland managed under cutting. Changes in nutritive value is mainly supported by plant related measurements like development state determination, leaf to stem proportion, and their synchrony in relation to maturity & response to the simulated biotic stress condition. These relevant information are useful to understand changes in plant morphology, phenology and forage quality, as a result of a changing climate. Predicting the response of the forage crop to stress conditions will help to adjust management practices, determine the optimum harvest date at the proper stage of maturity to achieve highest nutritive value, which will be positively reflected on the animal’s performance. This will end up with a profitable, environmentally friendly grassland-based dairy production system.
