This trial aims to test the effectiveness of various granular and liquid nitrogen products, two nitrogen timings and two nitrogen dressings on yield and grain quality.
Significant differences were found in grain protein % only with treatments 3, 7 and 2 all having the highest grain protein. There were no significant differences in other grain quality parameters or in yield. This is likely to be due to the late timing of all nitrogen applications and a reasonably high soil Nitrogen content to start with (approximately 176 kg/ha).
