PhD Studentship: Forage from multi-species pasture mixtures and effects on silage quality.
Multi-species swards offer significant promise as one of the tools to address sustainable intensification. They can optimise resource utilisation, especially when they contain agronomic varieties of grasses and legumes. Their ability to fix atmospheric nitrogen dramatically improves their resource use efficiency, and dramatically reduces their reliance on inorganic fertilisers and the consequent environmental concerns. Much, however, remains to be learned about the forage quality characteristics of multi-species grass-legume mixtures, and especially their use and management for high silage quality. This research will address this topic.
This 4 year PhD project will investigate the potential of a multi-species sward mixtures consisting of three plant functional groups (grasses, legumes and forage herbs) for conservation as silage when compared with perennial ryegrass monocultures and perennial ryegrass – white clover swards. Experimental plots will be established at Teagasc, Dunsaney, Co. Meath. Sward types, managed under various nutrient input levels will be compared in terms of the efficiency of the conservation process during ensilage with particular emphasis on the fermentation, effluent production and aerobic deterioration processes and the identification of associative effects where these occur between species.
The PhD award provides a stipend of €22,000 per annum. University fees are paid by the student from the stipend. The PhD will start in September 2013. The successful candidate will register with the School of Agricultural Science and Food Science at University College Dublin for a PhD degree. The research will be mainly carried out at the Teagasc Research Centre, Dunsany, Co. Meath, under the supervision of Dr. Padraig O’Kiely (Teagasc) and Dr Helen Sheridan (UCD).
