Field response of coffee clones to inoculation with consortium of arbuscular mycorrhizal fungi in the Amazonas Region, Peru

Abstract

The field responses of coffee clones to inoculation with consortium of arbuscular mycorrhizal fungi (AMF) and the application of different doses of compost in coffee clones (Caturra variety) under field conditions are evaluated. The mycorrhized and acclimated coffee clones were installed in a definitive field considering a randomized complete block design (RCBD) with factorial arrangement: factor A (3 consortium of AMF and a control without inoculum) and factor B (2 doses and a control treatment without compost), with 3 blocks. After 295 days after sowing the following variables were evaluated: plant height, number of branches, length of extraradical mycelium, mycorrhizal colonization and number of spores. The results indicate significant statistical differences in all consortium of AMF and compost doses studied. Therefore, the study shows that the inoculation of coffee clonal plants with AMF consortiums and the application of compost has positive effects on the morphological development of coffee plants.
