A group of students from Co. Cork have been recognised at the BT Young Scientist and Technology Exhibition 2025 for an agricultural science project using total leaf-area as a predictive tool for determining below-ground growth of selected root-crop plants.
Alvy Fitzgerald, Anna Duggan, Leah O’Sullivan from St Mary’s Secondary School, Mallow claimed the Teagasc Special Award and 1st Junior Group in the Biological and Ecological category for their outstanding scientific achievements.
The award-winning project, was titled “An Investigation into using Total Leaf-Area as a predictive tool for determining below-ground biomass at all stages in the growth of selected Root-Crop Plants”.

Teagasc said that the project “showcased the students’ dedication, creativity, and passion for scientific inquiry in agricultural research”.
“Their teamwork showcased not only their academic skills but also their talent for tackling real-world problems with creative solutions,” the authority added.
The team worked to develop and present their project under the guidance of their teacher Rory Coote.
Teagasc said that the project stood out for its thorough research, experimental methodology, and the potential impact in improving the efficiency and sustainability of root crop farming.
Alvy Fitzgerald said the team was amazed by the accuracy of their model in predicting plant growth.
While her teammate Anna Duggan explained that they used a drone to scan the leaf area this year, instead of the manual method they tried last year.
The idea for the project stemmed from a first-year science class, where the students learned about photosynthesis and grew curious about the connection between leaf size and root crop growth.
Leah O’Sullivan, the final member of the team, said that “a future in agricultural science is definitely on the horizon” for the students.
Award
The Teagasc Special Award, presented by the Professor Frank O’Mara, director of Teagasc, recognises the project that best demonstrates a thorough understanding of the science of agricultural or food production.
The students will also be invited to visit one of the Teagasc sites to learn more about our work in this area.
“The students should be incredibly proud of their remarkable achievements, and we wish them continued success in their scientific journeys.
“Their dedication, curiosity, and passion for scientific discovery are truly inspiring.
“This accomplishment not only showcases the exceptional talent within their school but also underscores their commitment to addressing real-world challenges in agriculture and food research,” Professor O’Mara said.
1,000 students from schools across the island of Ireland took part in this year’s BT Young Scientist and Technology Exhibition.
