Wider rows for larger cereal grain in low rainfall locations
Aims

To develop systems to protect grain quality and yield in a low rainfall area. Trying wider rows to conserve moisture instead of fallow.

Key messages

The results, even after relatively good spring rains, support the idea of conserving soil moisture between wide rows and reducing drought effects.
