A pot experiment was conducted to investigate the translocation of N in pods during siliqua developing of oilseed rape using 15 N‐urea. The 15 N was applied on the surface of pods at lower stem in three periods after flowering. At maturity the hulls and seeds of pods at different parts of plants were subjected to analyse N content and 15 N abundance and calculate recoveries of N applied. 79.1–84.3 % of labelled N applied were recovered from the total pods including 75.3–80.4 % in labelled pods. A great part of the N was translocated in seeds, the later the labelled N application, the more proportion of N in seeds was. Application of MgSO 4 combined with urea promoted the uptake and translocation of N, but not at a significant level.
