Increasing canola seeding rate reduces annual ryegrass (ARG) seed production....
-
Lime incorporation through suitable tillage treatments increased subsoil pH to the depth of incorporation faster than application to the surface....

-
Surface application of at least 2t/ha lime will increase yield within 1–8 years of application, however, higher lime rates will maintain and improve subsoil pH over time and might increase yield further....
-
To identify the main source of ice nucleation activity (INA) and track their temporal changes from flowering to ripening stages of wheat plants grown under contrasting stubble management (stubble retained and burnt)...
-
Break crops, such as canola and pulses, can be part of a profitable crop rotation in the low rainfall zone...
