Increasing the legume component pastures is beneficial for animal production and health, and environmental sustainability due to the fixation of nitrogen by legume-associated bacteria.
Sensitivity to drought is a major limitation to broader perennial legume adaptation across much of the high rainfall permanent pasture region of SE Australia. Strong evidence exists that elevated levels of phosphorus and lime improves pasture persistence and recovery following drought. Potassium (K) is also implicated in pasture response to drought due to its known internal function in osmoregulation, including the control of water loss through stomata. However, little previous research has explored the extent to which increased K nutrition may improve drought tolerance of pasture legumes, or through which mechanisms increased persistence might be achieved. Micronutrients such as molybdenum (Mo) and boron (B) are also very important in legume growth and persistence, but their effect on drought tolerance is also unknown.
This project will use a series of glasshouse and field experiments to examine the effect of K, Mo and B on the response of a drought-sensitive forage species that is of international significance, white clover (Trifolium repens L.).
