Efecto del EcoMic® y el Pectimorf® en el crecimiento de plántulas de Leucaena leucocephala cv. Cunningham.

The study was conducted at the Pastures and Forages Research Station Indio Hatuey in order to evaluate the effect of the bioproducts EcoMic® and Pectimorf® on the growth in nursery of Leucaena leucocephala cv. Cunningham. The treatments were: 1) control, 2) inoculation with EcoMic®, 3) imbibition in Pectimorf®, 4) inoculation with EcoMic® plus imbibition in Pectimorf®. A completely randomized design was used, with three replications. The evaluated variables were: emergence from the seeds, seedling height, number of branches and root length. The emergence was higher (71,43 % of seedlings emerged 35 days after seeding) in the treatment that consisted in imbibing the seeds in Pectimorf® during 16 h. The control was higher and differed significantly from the others in the variable number of branches. Regarding height, the imbibition in Pectimorf® and the control did not differ statistically, and the treatments inoculated with EcoMic® alone and its combination with Pectimorf® showed lower growth; however, these last two ones had incidence on a higher root growth of the leucaena seedlings. The imbibition in Pectimorf® during 16 h caused higher emergence from the seeds, while the treatments inoculated with EcoMic® showed the highest root growth; this indicates that it is possible to reduce the nursery period in this species.
