Shading effects on establishment of stylosanthes Campo Grande
There is increased interest in shading effects on establishment of forages, especially with regard to associations of forage species and trees in sylvopastoral systems. The object of this study was to evaluate the influence of four levels (0, 25, 50, and 75%) of artificial shading on the 16 variables: plant height (PH), root dry matter (RDM) , stem dry matter(SDM) , leaf dry matter (LDM), aerial parts dry matter (APDM), total plant dry matter (TPDM), nodules dry matter (NDM), aerial parts: root ratio (AP/R), leaf:stem ratio (L/S), number of leaves (NL), leaf area (LA), specific leaf area (SLA), leaf area ratio (LAR), root matter ratio (RMR), stem matter ratio (SMR), and leaf matter ratio (LMR), in the establishment phase of stylosanthes Campo Grande plants (seed mixture of 80% Stylosanthes macrocepha and 20% S. capitata). The experimental design was a randomized blocks with three replications. The highest values for PH, SDM, LDM, APDM, TPDM, NL, and LA of stylosanthes Campo Grande were obtained with 75% shading and this level is recommended for use in pastoral-forest and agropastoral-forest systems.
