Most previous studies have examined the effects of phosphorus (P) on source\u2010 or sink\u2010related traits separately under normal growing conditions, whereas quantitative assessments of the extent to which P mitigates yield loss under post\u2010silking source\u2013sink imbalance remain limited. A 2\u2010year field experiment was conducted in Xinjiang, China, using two P application rates (0 and 150\u2009kg P\n                      <jats:sub>2<\/jats:sub>\n                      O\n                      <jats:sub>5<\/jats:sub>\n                      ha\n                      <jats:sup>\u22121<\/jats:sup>\n                      ) combined with post\u2010silking defoliation (L1\u2013L3) and ear\u2010removal (E1 and E2) treatments to simulate source limitation and sink restriction, respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>Under defoliation\u2010induced source limitation, P application significantly increased ear\u2010leaf net photosynthetic rate, delayed leaf senescence, and improved grain\u2010filling performance, with the buffering effect becoming stronger as defoliation severity increased. Accordingly, yield loss was significantly reduced, and the yield\u2010buffering capacity of P increased from 19.39% to 37.76% with increasing defoliation intensity. Under ear\u2010removal\u2010induced sink restriction, P fertilization maintained higher photosynthetic performance and enhanced the grain filling of the remaining kernels, thereby increasing 100\u2010grain weight. As a result, grain yield under P application was 15.93\u201318.39% higher than that under P deficiency at the same sink\u2010restriction level. Across both source\u2010 and sink\u2010limited conditions, P fertilization also maintained greater aboveground dry matter accumulation, indicating a better overall growth status under post\u2010silking stress.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>Phosphorus fertilization enhanced maize yield resilience under post\u2010silking source\u2013sink imbalance by sustaining photosynthetic source capacity and supporting grain sink activity during grain filling. Its beneficial effect was more pronounced under source limitation than under sink restriction. These findings indicate that adequate P nutrition helps stabilize yield formation mainly through coordinated regulation of source function and sink performance under post\u2010silking stress. \u00a9
