Lucerne Yield Gaps in Argentina.
We compared two forage landcovers, the sequence oats-maize and pure alfalfa across a mean annual precipitation gradient.
We compared resource use efficiency of forage crop sequences and temperate perennial pastures.
We evaluated the capacity of APSIM to simulate the growth rates and predict the dry matter yield of Lucerne (_Medicago sativa_ L.) and annual ryegrass (_Lolium multiflorum_ Lam.) in contrasting climatic regions of Argentina and Australia.
