Herbal ley project wins Teagasc award at BT Young Scientist
A project which investigated whether agriculture can be both profitable and sustainable for the future was the recipient of the Teagasc Special Award at the BT Young Scientist and Technology Exhibition 2020.
Three fifth year students from Millstreet Community School in Cork (Bevin Murphy, Darren Kiely and Omar Daly) received the award for their project titled: ‘Herbal Leys – Milk Production for the Future’.
An herbal ley is a seed mixture of grasses, legumes and herbs, which – according to Teagasc – bring a range of benefits to forage, livestock health and soil fertility.
The project was selected as the Teagasc Special Award winner by judges at the 56th BT Young Scientist and Technology Exhibition (BTYSTE) 2020, which took place in the RDS from January 9 to January 11.
They were presented with the award by the director of Food Technology Transfer, Teagasc, Declan Troy.
The students did a comparative analysis of four dairy farms – two using a conventional perennial ryegrass grazing system and two UK-based farms using herbal leys.
They also conducted a practical experiment using raised beds at their school simulating grazing conditions over a growth season.
The students explained: “One of the plants that stood out was chicory, which has a long tap root, making leys more drought-resistant.”
Student Bevin Murphy said: “Certain herbs included in the mixtures – such as Chicory – have anthelmintic properties, which helps to reduce the worm burden in livestock.”
The students also noted on their farm visits that there was a noticeable presence of wildlife on the herbal ley farms, particularly butterflies and bees, which are attracted to the plants.
We believe that herbal leys are the future of farming in Ireland. This subject is close to our hearts as two of our group members are from farming backgrounds and would like to make a career in farming.
The Teagasc special award is presented to the project that best demonstrates a thorough understanding of the science of agricultural or food production, or the use of science to improve technologies available to agricultural or food production.
