This dataset contains the result of extracting data of plant biomass and plant N concentration from 36 papers with a total of 4454 observations for 19 major crop species from 16 countries around the globe. This dataset is relevant to develop more universal critical N dilution curves, help to pinpoint factors limiting plant N status (and N nutrition index, NNI), and lead to refine N recommendation for major crop species under broad scenarios of different genotypes, environment, and management (GxExM).
