Contributor Hart Field Site Group
Trial location(s) Site 5, Hart, SA
Long-term cropping systems trial locations
Aims

To compare the performance of three seeding systems and two nitrogen strategies

Key messages

Barley grain yield was not affected by tillage treatment averaging 4.25 t/ha. The medium nitrogen level increased grain yield by 0.61 t/ha compared to the high nitrogen level
