Arbuscular mycorrhizal fungi (AMF) play an important role in plant growth.
This research aimed to evaluate the agronomic efficiency of a Rhizophagus intraradices inoculant (mycorrhizal fungi) in combination with phosphate fertilization in grain yield of corn under different edaphoclimatic conditions.
Experiments were conducted in five Brazilian states (Goiás, Mato Grosso, Minas Gerais, Rio Grande do Sul and Santa Catarina) in a 2 x 3 factorial scheme, with two inoculation treatments (inoculated and non-inoculated seeds) and three doses of phosphate fertilization (0, 50 and 100% of the recommended P).
At the end of the crop cycle (stages R4-R5), inoculation provided increases in biomass (average of 48%) regardless of the applied dose of P, higher P absorption, and a 54% average increase in grain yield. In conclusion, the mycorrhizal inoculant Rootella increased biomass yield, P uptake and corn grain yield under different edaphoclimatic conditions, especially in soils that originally had low or medium levels of available P.
