Impact of summer cropping on subsequent wheat crops locations

To investigate the impact of summer cropping on subsequent winter crop (wheat yield). To dtermine nitrogen (N) response of wheat following summer crops.

Key messages

Adequate crop nutrition following summer crop is essential for optimised winter grain yield. Soils moisture was not limiting this season, therefore wheat responses were driven by crop nutrition.
