Comparing different nitrogen products for yield and grain quality repsonses in wheat locations
Aims

The objective of this trial is to test the effectiveness of the two different forms of nitrogen, two nitrogen timings and two nitrogen
timings and two nitrogen dressings on yield and grain quality. 

Key messages

There were no significant differences in yield between the forms of nitrogen product used in the trial, however there was a trend towards a higher yield where nitrogen was used. There was a significant difference in grain protein between the different treatments.
