 This study examined the effect of arbuscular mycorrhizal fungus, AMF, rhizophagus interattus' inoculum on pepper growth and physiological parameters under elevated soil P concentrations from organic greenhouse production with enhanced soil salinity. The study found that AMF inoculation generally enhanced growth, fruit yield, and number of fruits per plant when applied at planting time in CV raco cultivated in high P saline soil, but did not have any significant differences in comparison with non-mycorrhizal inoculated plants in CV arloquin grown under the same conditions. The study highlights the potential of AMF in enhancing pepper growth and yield even in high soil P, but also emphasizes the complexity and interaction of involved genotypes of pepper and AMF, the method and time of inoculation, the system of pepper production, and environmental conditions, as well as assays that need to be performed to verify positive effects.
