Trial Discussion/Summary:
There was no significant differences between treatments in this trial.
The site was a very non-responsive site to fertiliser with a good background
level of all nutrients, a low PRI (19.2) and a good nitrogen level helped by the
field pea crop in 2002.
Disease pressure was minimal with low levels of Septoria nodorum/Yellow spot
visually identified through the growing season.
Growing season moisture was also not limiting.
Potentially a very useful trial with the aim of driving more proactive
farming practices - just not the year or site to show it!
