Manipulation Of The Soil Seed Reserves Of Bromus Diandrus And B. Rigidus By Enhancing The Breakdown In Seed Dormancy., A H. Cheam

Experimental Summaries - Plant Research

Location: South Perth Field Plots

Previous studies on the seed bank of Bromus diandrus indicated that shallow burial of newly shed seeds enhanced the breakdown in seed dormancy over the summer period. To bury the Bromus seeds one practical approach is to introduce sheep into the paddock.
This study is a repeat of the previous work but included B. rigidus, another species of Bromus, that is commonly ground growing in association with B. diandrus.
Location: South Perth Field Plots.

All treatments yielded significantly better than the control however there was no difference between herbicides, rates of use or additives. The exception being 0.75 L Hoegrass +WA which yielded significantly less than Grasp + oil.

Experimental Summaries - Plant Research

Treatments were applied in December 1987. Height of the Bracken made application by boom difficult due to inability to adequately raise the boom to give clearance. Some brushing of the Bracken with the boom was unavoidable. Assessment of the trial will be made in March 1988.
