VARIABILIDADE NAS CARACTERÍSTICAS DO PASTO DE CAPIM-PIATÃ EM SISTEMA SILVIPASTORIL

The objective of this study was to verify the variations of the structural
characteristics and the mass of forage of piatã grass in different sampling points in a luminosity gradient of a silvipatoril system with density of 357 ha-1 trees. The
experiment was carried out at Fazenda Boa Aguada, located in the municipality of
Ribas do Rio Pardo-MS. The evaluations were carried out in the period from
07/07/2017 to 01/01/2017. The experimental design was a randomized block design.
The treatments consisted of five equidistant sample points (A, B, C, D and E), in a
transect perpendicular to two rows of trees, with points A and E close to the rows of
trees. The dry mass of leaves (kg ha-1 of DM), dry mass of leaves (kg ha-1 of DM),
dry mass of leaves dry mass of dead material (kg ha-1 of MS), leaf:stem ratio and
green material ratio:dead. The grass of piatã did not present variations in the
structural characteristics in different points of sampling within a silvipatoril system in the first year of evaluation.
