Abstract

RIZO-ALVAREZ, Maritza et al. Influence of EcoMic^® and Pectimorf^® on the establishment of Leucaena leucocephala (Lam.) de Wit. cv. Cunningham. Pastos y Forrajes [online]. 2018, vol.41, n.3, pp.183-188. ISSN 0864-0394.

The objective of the study was to evaluate the influence of the biofertilizer EcoMic^®, the bioactive product Pectimorf^® and their combination, on some morphobotanical variables during the establishment of Leucaena leucocephala (Lam.) cv. Cunningham. For such purpose a randomized block design was used with three replicas, and the following treatments: T1: thermal scarification (control), T2: inoculation with EcoMic^®, T3: imbibition in Pectimorf^®, T4: imbibition in Pectimorf^® + inoculation with EcoMic^®. The variables height, number of branches and stem diameter were measured until the plants were 12 months old. The best values of each variable were obtained when, after thermal scarification (T1), the seeds were inoculated with EcoMic^® (T2) or imbibed in Pectimorf^® (T3), without significant differences between them; while the control showed the lowest values. The height increased in T2 and T3 by 12 %, with regards to T1. It is concluded that the imbibition in Pectimorf^® or the inoculation with EcoMic^® of the seeds from L. leucocephala cv. Cunningham, after thermal scarification, improved the biological response of the plants during the establishment regarding their height, number of branches and stem diameter. Hence they can be used indistinctly, in order to reduce such period in the animal husbandry systems where it is used.

Keywords : height; scarification; inoculation; seeds.
