MARTIN, Gloria M; REYES, Reynerio  y  RAMIREZ, Juan F. Coinoculation of Canavalia ensiformis with Rhizobium and arbuscular mycorrhizal fungus in two soils from Cuba. cultrop [online]. 2015, vol.36, n.2, pp.22-29. ISSN 0258-5936.

To evaluate the response of jack bean (Canavalia ensiformis (L.) D.C.) to the coinoculation with strains of Rhizobium and arbuscular mycorrhizical fungus (AMF), it was carried out an experiment under microplots conditions that contained Nitisol soil coming from the Department of Agricultural Services of the INCA, in San José de las Lajas, Mayabeque, and another soil from the Station of Grasses and Forages of Cascajal, Villa Clara (Ferruginous Nodular Gley). Four strains of Rhizobium were studied (Can 2, Can 3, Can 4 and Can 5) and two strains of AMF (Glomus cubense (INCAM 4) and Rhizophagus intraradices) (INCAM 11) for the Nitisol soil and Glomus cubense and Funneliformis mosseae (INCAM 2) for the Nodular Gley soil more the corresponding controls without inoculation, for a total of 15 treatments for each soil type, which were distributed in a totally randomized design with factorial arrangement (5 x 3) and three repetitions. The mycorrrhizic symbiosis indicators and the yield of dry mass were evaluated. The results showed that the jack bean responded to the coinoculation Rhizobium-AMF in both types of soil. The best behavior in the strains of Rhizobium was obtained with can 3 for the Nitisol soil and Can 3, Can 4 and Can 5 for Nodular Gley soil, and the best strain of AMF were, in that order, G. cubense and F. mosseae for one and another soil, respectively
