The effect of products on percent frequency of mycorrhizal colonization
was variable and was highest with PHC Biopak (87.4%)
and PHC Colonize (85.6%) inoculation in the Vertisol in the Rhodic
Ferralsol, Rhizatech inoculation had the highest percent frequency
of mycorrhizal colonization (76.1%) while the control had the least
(34.6%). Similar to the observations made on percent intensity of
colonization, inoculation of plants with ECO-T had the highest percent
frequency of colonization (93.3%) in the Humic Nitisol and
MYCOR inoculation had the highest percent frequency of colonization
(73.3%) followed by Rhizatech (60%) while ECO-T had the least
colonization (22%) in the conventional media.
