Summary
This field trial investigates how co-inoculation with plant growth-promoting rhizobacteria and arbuscular mycorrhizal fungi influences water-use efficiency and yield in dryland wheat production. The study appears to demonstrate moisture- and phenologically-dependent interactions between these microbial groups, suggesting that their effectiveness varies with soil water availability and crop development stage. The findings may inform microbial inoculant strategies for improving water productivity in water-limited cereal systems.
UK applicability
Whilst UK wheat production typically benefits from higher rainfall than true dryland systems, findings on microbial inoculants' role in water-use efficiency could inform practice in drier regions of the south and east of England, particularly under increasingly variable precipitation patterns.
Key measures
Water use efficiency, grain yield, plant growth parameters, potentially soil moisture and nutrient uptake under varying precipitation or irrigation regimes
Outcomes reported
The study examined how plant growth-promoting rhizobacteria (PGPR) and arbuscular mycorrhizal (AM) fungi, applied singly or in combination, affected water use efficiency and yield formation in wheat grown under dryland conditions. Measurements as suggested by the title included interactive effects across different moisture levels and growth periods.
