Lodging in tef reduces yield, and N application worsens its impact. This study assesses the combined effects of arbuscular mycorrhizal fungi (AMF) and N fertilizer on lodging and yield in tef. Two groups of AMF (Inoculated and noninoculated) and five levels of N (0, 46, 92, 138, and 184 kg/ha) were arranged in two consecutive years. The analysis of variance revealed that plant height (PH), panicle length (PL), total number of tillers (TNT), lodging index (LI), shoot biomass yield (SBY), grain yield (GY), and harvest index (HI) were significantly influenced by AMF, N levels, and their interactions (P< 0.05). AMF inoculated groups increased PH by 59.87%, PL by 18.20%, TNT by 87.13%, SBY by 30.14%, GY by 37.60%, HI by 10.71, and reduced LI by 229.63%, as compared to the non-inoculated. AMF-inoculated groups did not show a change in LI with increasing N levels, indicating AMF inoculations minimize the impact of excessive N application from causing lodging. In contrast, non-inoculation showed a trend of increasing LI with higher N levels, reducing yield. AMF-inoculated tef crops do not experience lodging, even with higher N levels which can help prevent yield loss caused by lodging from N application.
