Responses of barley, pea, and maize to inoculation with different vesicular-arbuscular mycorrhizal fungi in irradiated soil

Summary

The efficiency of different VAM fungi was investigated by inoculating barley, pea, and maize with different VAM fungi in irradiated soil in pots buried in the field. VAM frequency, growth and nutrient uptake were measured.

In barleyGlomus epigaeus (CA) andG. macrocarpus (CA) were the most efficient out of 11 tested species and increased yield of grain by 24% and 21%, though they were not significant according to oneway analysis of variance. In pea, yield of grain was significantly increased from 46% to 104% (mean=68%) by 7 out of 10 tested species and by 105% by application of P fertilizer. The most efficient species wereG. epigaeus (CA),G. mosseae (GB), andG. etunicatus (CA). In maizeG. mosseae (GB) andG. caledonius (DK) increased total yield significantly by 59% and 47% in one experiment and in another experiment yield of cob was increased by 68% byG. mosseae (GB), 72% byG. caledonius (DK), and by 153% by application of P fertilizer.

This experiment demonstrated that responsiveness to inoculation by VAM fungi differed among plant species, and that efficiency of different VAM fungi differed.
