Crop Science & Agronomy

How field crops grow, yield and respond to management, weather and stress.

Crop science and agronomy study how field crops - cereals, oilseeds, legumes, root and tuber crops, fiber and sugar crops, forages - grow and produce yield, and how that is shaped by management decisions such as sowing date, plant density, crop rotation and intercropping.

A large part of the discipline is crop physiology: how plants respond to drought, heat, waterlogging, salinity or rising atmospheric CO2, and which traits and practices keep yields stable under those conditions.

Where research is heading

Typical research questions

  • Which management practices close the gap between actual and attainable yield?
  • How do crops respond physiologically to drought and heat stress?
  • When do intercropping and diversified rotations outperform monocultures?
  • How should forage and grassland systems be managed for yield and persistence?
