Implication

Controlled field trials reveal variable yield benefits from mycorrhizal inoculation in wheat and barley, indicating root colonization does not bypass the need for applied phosphorus.

Key Points

To assess how vesicular-arbuscular mycorrhizal inoculation, methyl bromide soil fumigation, and phosphorus fertilization influence crop growth and nutrient uptake across consecutive cereal plantings.
Evaluated spring wheat (Triticum aestivum cv. Highbury) in two field experiments (1980 and 1981) testing factorial combinations of methyl bromide fumigation, Glomus mosseae inoculation, and superphosphate additions up to 60 kg P/ha.
Planted subsequent winter barley on the same plots without renewing fumigation, inoculation, or phosphorus treatments to trace residual colonization and yield effects.
Soil fumigation reduced native mycorrhizal infection in both years, causing an approximate 25% grain yield reduction alongside elevated straw growth and shoot bromine content in 1981.
Inoculation enhanced 1981 grain yields on fumigated plots by approximately 0.75 t/ha across all phosphorus rates and increased tissue phosphorus concentrations, but had little effect on non-fumigated plots.
Inoculation and fumigation effects attenuated over successive crops as fungal propagule counts increased across all treatments, while harvest yields continually responded to applied phosphorus despite high infection levels.
