BOVER-FELICES, Katia; LOPEZ-VIGOA, Onel; RIZO-ALVAREZ, Maritza  e  BENITEZ-ALVAREZ, Miguel Ángel. Effect of EcoMic® and Pectimorf® on the growth of Leucaena leucocephala cv. Cunningham seedlings. Pastos y Forrajes [online]. 2017, vol.40, n.2, pp.102-107. ISSN 0864-0394.

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.
