Evaluating different nitrogen products in wheat locations
Aims

To test the effectiveness of the two different forms of nitrogen, two nitrogen timings and two nitrogen dressings on yield and grain quality.

Key messages

There was no difference between nitrogen treatments for grain yield and all grain quality parameters except for TGW (thousand grain weight). The very dry year had an effect with limited moisture available to assist in nitrogen uptake at growth stage 31, when all N was applied.
