ABSTRACT Most rice production is conducted in flooded (anaerobic) soil conditions, but aerobic cultivation presents several potential benefits: increased grain water use efficiency (gWUE), reduced methane emissions, and minimised loss of phosphorus (P). Arbuscular mycorrhizal (AM) fungi are more effective at colonising functioning under this rice‐AM association could increase both gWUE P acquisition (PAE). We used a precision irrigation platform to apply watering treatments (60% or 80% field capacity) throughout the experiment. Four commercial Australian varieties were grown with without inoculation Rhizophagus irregularis , addition fertiliser 10 25 mg kg –1 soil. Plants maturity (134–188 days after planting), which yield, plant use, gWUE, PAE determined. Overall, R. all four (by mean 14.4%), yield two varieties. Grain yields primarily constrained by low availability (mean 48.4% reduction), also limited Of four, Topaz showed greatest response AM fungal inoculation, qWUE PAE. There for efficiencies aerobically rice. However, extent these benefits depends on specific variety, highlights importance variety selection transitioning temperate regions enhancing resilience climate change.
