Main Article Content
Abstract
In order to select the most efficient strains
of arbuscular mycorrhizal fungi (AMF) to improve the
nutritional status and productivity of Guinea grass,
the following research was carried out on a Lixiviated
Ferralitic Red soil. It was conducted at the Cattle Production
Enterprise "Niña Bonita", located in the Bauta municipality,
Artemisa province, Cuba. In it Funneliformis mosseae,
Glomus cubense and Rhizophagus intraradices AMF strains
plus a control without inoculation were evaluated, in a latin
square design. A solid mycorrhizal inoculant formulated with
each of the strains was used, containing 35 spores per gram
of substrate; which were evenly distributed over the freshly
cut grass, with a manual backpack sprayer loaded with a
suspension of the AMF mycorrhizal inoculant and water
at a 1:10 ratio, to reach a dose of 20 kg ha
of inoculum.
It was found that the inoculation of G. cubense produced a
higher frequency and intensity of mycorrhizal colonization,
a higher number of spores in the rhizosphere and the tallest
plants, higher concentrations of N, P and K in the biomass
of the aerial part and the highest yield of pasture. The effect
of this strain remained in the pasture up to 270 days after
inoculation. It is concluded that G. cubense was the most
efficient strain to improve the nutritional status and increase
the productivity of Guinea grass established on the above In order to select the most efficient strains
