This
project evaluates the potential of biofertilizer application of
mycontizal arbuscular (MA) fungi, arming to reduce propagation problems,
hardening and nutrition of micropropagated plants, in plantain, yam, and
cassava, and to improve the seed production of high quality, seeds to be
used by small farmers of the Caribbean region.
Inoculation with MA fungi, in the post in
vitro weaning stage of cassava plantlets report a survival
percentage of 83% under treatment with Acaulosphora
mellea, and 90% with Glomus
sp in two cultivar (CM 3606-4 and MCol 2215).
Subsequently, cultivar CM 3606-4’s value in field conditions
present an increase in its growth of 57% after inoculation with Glomus
sp. The mycorrhizal
colonization percentage was evaluated by differential staining of root
samples after 30 days of inoculation finding that 87% of the root length
was colonized. The
biofertilizer application is a valuable alternative for increasing
sustainability in many important tropical crops, such as cassava, and
makes necessary the scale up of innovative technologies.
For these reasons two pilot plants have been established to
produce MA fungi
