Although not a typical rotation, these crops were selected to maximise the relevance of our results to industry by including the most commonly grown crops in the Tayside region and those that form the basis of much of the crop research at the JHI.
In the baseline years 2009 to 2010, all 6 fields were sown with maize to even out some of the within-field variation due to previous cropping histories and to provide a C4 input to the soil to provide an initial measure of carbon turnover.
In the first rotation (2010/11 to 2016), 5 different cultivars of each crop were sown in 18m wide strips in each half field to assess differences in cultivar response to the reduced input system.
In the second rotation (2016/17 to 2022), 2-3 cultivars are compared over larger blocks in each half field to allow more commercially realistic crop management and better assessment of the spatial variation across the fields.
Crop varieties are selected to include one industry standard to compare against varieties with a range of environmental traits – resource use efficiency, weed suppression, disease resistance etc.
