Next generation tools to estimate the forage-based yields under climatic and management practices over different environments in Europe

More information 

Grasslands ecosystem plays a role in food production systems, once they cover roughly 40% of total arable land globally. Most of those regions present average output yields (milk and meat) by far from its biological potential possibly due low forage availability, becoming therefore of high interest for assessments related to yield gap closure and intensification potential.

The use of tools such crop simulation models might be useful to investigate the impact of genetic x environment x management (GxExM) conditions and purpose strategies to optimize the use of natural resources towards a sustainable agriculture.

The speech will elucidate the long-term modelling simulation using Apsim-NextGeneration to answer the follow research questions:

• What is the impact of climate, water management and fertiliser rates on forage-based yields in different grassland environments in Europe.
• When – and how much – grazing operations (cuts) we could have in each agronomic scenario.
