To compare the performance of three seeding systems and two nitrogen strategies.
This is a rotation trial to assess the longer term effects of seeding systems and higher fertiliser input systems on soil fertility, crop growth and grain yield and quality.
Key messages
There was no significant difference between seeding systems or level of nutrition on grain yield or oil content.
Soil available N was the same for all seeding systems pre-seeding however, the no till treat had released more available soil N.
In-season more available N was measured in the high nutrition treatment compared to the medium.
