The relative importance of soil, climate and management factors in explaining global yield patterns. The importance index values computed based on the permutation method within the RF models are scaled crop by crop to have the value with the highest importance to be one so that we can compare different crops and different dataset combinations. The gray bars indicate the multicrop and multidataset averages of importance index values
