To compare pre-emergent herbicides in the control of problem weeds in wheat.

To compare a group of English winter wheats, many of which are milling grade, with two of the leading red wheats, Revenue and Alberic.
 

To evaluate the individual and combined effects of two growth regulators, Cycocel (Chlormequat) and Moddus (Trinexapac-ethyl) on lodging, yield and yield parameters. Nitrogen and gibberellic acid treatments were also included to investigate their impacts on lodging. 

To investigate how nutrition can help mitigate waterlogging losses in wheat, canol and faba beans after a wet winter

To determine the relationship between nitrogen rate and the need for disease control in winter wheat in the high rainfall zone environment of Tasmania.

The aims of this trial were to:
• Compare early sown dual purpose wheat, barley, triticale and oat varieties for DM production, feed quality, recovery from grazing and grain yield.
• Compare DM and feed quality of cereals with a tetraploid annual ryegrass used for over-winter grazing prior to seed production.
• Assess the potential of canola for grazing and grain production.

The objective of this study was to evaluate existing and future wheat varieties for performance when sown early (March) without grazing.

The aim of these trials was to compare existing wheat varieties under dryland and irrigated conditions, evaluate new breeding material and continue to assess the disease responses of all germplasm.

The objective of this trial was to compare a commercial plant density for dual purpose and grain-only production with reduced rates
comparable to that used for early sowing in the UK.

The aim of this trial was to determine the effect of grazing (cutting) on grain yield of early sown wheat and triticale in comparison with uncut treatments.
