The aim of the trial is to identify the best nitrogen timing and rate in order to maximize profits for the widely grown cultivar Kellalac, in the local higher rainfall conditions of southern Victoria.
With no significant difference in yield across this trial (Table 4-11) it appears that the high soil nitrogen and variable season may have been too influential to repeat previous years’ results. Findings from this trial should still be reviewed, but not used solely to make strategic nitrogen management decisions in the future. Possibly one key finding may be that high N paddocks need little if any follow up N past crop emergence, depending on paddock history and seasonal outlook. Late leaf rust was present throughout this trial,
however it is not known if this was influential in determining yield outcomes.
