e1“This study investigated the agronomic performance and root characteristics of perennial ryegrass and mixed perennial ryegrass–plantain swards under intensive rotational grazing by dairy cows in Northern Ireland over two full grazing seasons (2023–2024)”
e6“Root assessments revealed perennial ryegrass swards had significantly greater fine root development ( p < 0.001), biomass ( p < 0.001) and surface area ( p < 0.001) to 30 cm soil depth, whilst mixed perennial ryegrass–plantain sward roots were fewer in number but exhibited slightly thicker diameters in deeper layers.”
