The adoption of conservationist systems such as agroforestry is indicative of
nutritional quality of forage species. The objective was to evaluate primary and
secondary macroelements in leaf tissue and dry matter content of Mombasa grass
(Megathyrsus maximus) with shade levels in Amazonia. The trial was allocated in a
completely randomized design, with six replicates for each of three treatments - three
levels of shading, totaling eighteen experimental units. The measured variables
consisted of values of the primary macroelements (nitrogen, phosphorus and
potassium) and secondary (calcium and magnesium) contents in the leaf tissue and
dry matter content of the Mombasa grass. Shading is an important factor in increasing
the nutritional value of the Mombasa forage, especially when considering the
macroelements for ruminants, which may reduce the nutritional load used for grazing
cattle in the silvopastoral system. On the other hand the low production of dry matter
requires a balance point. Thus, the treatment, shading 25% presented the best
performance from a productive and qualitative point of view. |
