Abstract

SUAREZ, Juan C; RAMIREZ, Bertha L  and  VELASQUEZ, Jaime E. Agronomic performance of five forage species under the cut and carry system on terrace and meson soils in the Colombian Amazon piedmont. Zootecnia Trop. [online]. 2008, vol.26, n.3, pp.347-350. ISSN 0798-7269.

The use of fodder trees in agroforestry systems as protein banks used by cut and carry system has been seen as an alternative technology to maintain or improve animal productivity and sustainability. Therefore, we estimated biomass production of five forage species subject to cut and carry located on two soils in the Colombian Amazon piedmont. A design of complete blocks was used at random, with factorial adjustment 2 x 5 (2 types of landscape by 5 treatments) and 4 repetitions. The results showed a variability in the production of biomass in each component (P <0.05) because of the differences between each species and the site which were sown. The leaf component varied from 1.942 for Cratylia argentea to 73 g DM/plant for Thichantera gigantean. For the stem component, production varied from 1,116 to 28 g MS/plant for Cratylia argentea and Thichantera gigantea, respectively. The higher production of biomass was for Cratilia argentea, meanwhile Thichantera gigantea had the highest ratio of leaf-stem. We found high production of biomass on meson soil and among species the values of total biomass for the component leaf+ stem for one year, were for Cratylia argentea, Gliricidia sepium, and Clitoria fairchildiana.
