Sorry which line graph is Denmark? Yields in Ireland are typically over 8 tonnes per hectare https://www.cso.ie/en/releasesandpublications/er/aypc/areayieldandproductionofcrops2016/Crop yields have been displaying a secular increasing trend in all regions of the world, over the entirety of the "OMG GLOBALWARMING!" period (1950-2018).
But apparently, Denmark had a bad year so, "OMG HUMANS ARE DESTROYING THE PLANET!"
... so maybe the yields in Denmark are too high for your graph
