Trial plan

As part of the AICC Crop Nutrition Club 2022, this on-farm winter wheat trial compared N rates from 140 to 260 kg/ha, including the N rate recommended by the Yara N tester. The trial was facilitated by a local AICC advisor, with support and Agronomics yield map analysis from ADAS.

Results summary: Yield increased from the lowest N rate (140 kg/ha) up to 220 kg N/ha, but there was little difference between 220 and 260 kg N/ha, although due to the small plot size, the yield results were not very precise. The best gross margin was probably achieved at around 220 kg N/ha.
