VIVAS-QUILA, NELSON JOSÉ  y  CHARO-ELVIRA, LUIS EDIBAR. RESPONSE OF THE PALM GRASS (Setariapoiretiana) TO THE SOMBER: A CHOICE OF PRODUCTION IN SYSTEMS SILVOPASTORAL. Rev.Bio.Agro [online]. 2014, vol.12, n.1, pp.161-169. ISSN 1692-3561.

The research was conducted at the Los Naranjos farm located in the Vereda La sale in the municipality of Cajibío of the Cauca Department. The shade of the trees do not allow the progress of the forage grown in your environment and are not known the shade-tolerant species that adapt to climate conditions medium and medium to low fertility soils.Was therefore undertaken a study on agronomic management and forage potential of palm grass (Setariapoiretiana) under three distinct shadow. The evaluation was conducted under the design in randomized complete block with 3 treatments and 4 replications. Treatments consisted of different percentages of shadow artificial using polisombra(free exposure, partial shade and shadow with 0,44 and 70% dark) mesh and repetitions (blocks) were the conditions given by the shadow of the forest around the project. The treatment that showed better agronomic performance in terms of dry matter production was T1 (free exhibition); no statistical differences were found for variables vigor, coverage, height, dry matter content; did not show damage by pests and diseases.

Palabras clave : Forestry; Response to the shade; Forage under shadow; Dark adaptation.
