Formatted Abstract/Summary
Current barley agronomic management guidelines were developed from research undertaken over twenty years ago. These guidelines are robust and are generally applicable to recently released and close-to-release barley varieties. However, do they maximise the productive and economic potential of these new varieties? In other words, do current barley varieties all have a similar response to the same agronomic practice and do they respond similarly to earlier barley varieties?

Research was conducted from 2002 to 2004 across northern NSW and southern Qld to determine how recently released and close-to-release barley varieties respond to differing plant populations and nitrogen rates. Phenology information has also been collected across the same region. In addition, a grower survey of current barley management practices was undertaken to assess the current level of management utilised when producing barley.

Variety and plant population effects on grain yield and grain quality attributes were significant; however a differential variety response was not evident. There were significant variety and nitrogen rate responses on grain yield and grain quality attributes and some variety by nitrogen rate interactions. Varieties also responded differently to changes in sowing date. The survey of management practices generally indicated that growers were actively managing barley.

These differences between varieties indicate that developing variety specific agronomy packages would be beneficial to growers and the northern barley industry. It is also likely that such packages would be adopted by growers considering their current levels of agronomic management.
