Abstract
Abstract Some fungal species have been shown to improve plant growth under drought conditions and to increase plant phosphorus ( P ) uptake from the soil. How moisture limitation, P availability and fungal inoculation interact to affect plant physiology and growth is, however, poorly understood. Here, we studied the combined effects of fungal (arbuscular mycorrhizal fungi ( AMF ) or P enicillium spp.) inoculations and phosphorus ( P ) fertilization (0, 45 and 90 kg ha −1 ) on the net rate of photosynthesis, water‐use efficiency, P uptake and growth of spring wheat ( Triticum aestivum var. Superb) under field conditions at two locations ( C astor and V egreville) in A lberta, C anada. Both fungal inoculation and P application increased the rate of photosynthesis. Under the same P level, AMF inoculation had a greater positive effect on the rate of photosynthesis than P enicillium inoculation. The AMF inoculation increased the instantaneous water‐use efficiency ( WUE i) of plants at C astor, but not at V egreville. Leaf carbon isotope discrimination ( CID , Δ 13 C ) increased with the rate of P application but was not affected by fungal inoculations. Phosphorus concentrations of stem and seed increased with both fungal inoculation and P application irrespective of location, with AMF inoculation showing the largest effects. The interaction between P addition and fungal inoculation was significant for stem P concentration in Vegreville. Both fungal inoculation and P application increased the leaf area index ( LAI ), biomass production and grain yield at both locations. Under the same P level, AMF inoculation had a greater positive effect on LAI , biomass production and grain yields than P enicillium inoculation. Morphological characters such as spike length and kernels/spike were also improved by fungal inoculation and P application at both locations. We conclude that the studied sites were deficient in P availability, and both fungal inoculation and P application improved P uptake and crop productivity, while the effect of fungal inoculation on water‐use efficiency was site specific.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
