Genetically modified crops are superior in their nitrogen use efficiency-A meta-analysis of three major cereals

Abstract It is currently uncertain to what extent genetic transformations of strategic crops (targeting diverse traits) have improved their N use efficiency (NUE), and what the key factors affecting their NUE are. Based on data collected from 130 publications, the effect sizes of genetic transformat...
