This study was conducted to determine whether the interaction between the erect panicle (EP) genotype and N-fertilizer application affects the source-sink ratio and N use efficiency (NUE) in yield formation processes. For two consecutive years, two EP rice genotypes with ‘Akitakomachi’ (AKI) and ‘Li...
