To assess the value of higher nutrition input for barley
• There was no significant yield difference in response to nitrogen or added nutrients (through fertiliser or manure).
• The high yields achieved despite varying N rates suggest that the N supply coming from the soil is very important for achieving higher grain yields.
• Despite only 10 kg N/ha from MAP at sowing being applied to the “0N” treatment, a yield of 11.91 t/ha was still achieved.
• There was a statistically significant trend for protein to increase with higher N rates.
• Screenings also rose with N rate with 0N having 0.9% versus 250N at 1.7%.
