Abstract

Three experiments were conducted on carbonated
loose Brown soils using Glomus intraradices strain, with the
objective of establishing an adequate and feasible methodology
for the mycorhizal inoculation of efficient AMF strains in
cassava crop. Several methods and inoculant doses were
compared, based on the overall seed recovery with different
amounts of inoculants (22-174 kg.ha
-1
), localized seed tip
recovery (11-14 kg.ha
-1
) and the traditional application of
inoculants to the soil beneath the seeds (617 kg.ha
-1
), all of
them performed at planting time. Inoculated treatments always
received 25 % of NPK mineral fertilizer rate for cassava crop;
they were also compared with other non-inoculated treatments
receiving 0, 25 and 100 %. It was found that any application via
recovery, even localized on seed tips, guaranteed a similar
effective mycorhization to high doses of inoculants applied to
the soil beneath the seeds. Inoculated treatments assured high
and similar yields to those obtained when applying the
recommended dose of mineral fertilizer for cassava crop (100 %
NPK) of the order of 35 t.ha
-1
, it showing quite a superior
mycorrhizal colonization percentage (60 %) to non-mycorhized
treatments (<8 %). Mycorhizal inoculation via localized
recovery on seed tips is recommended, due to its effectiveness
and the low amounts of inoculants.ha

required.
