“…When assessing the nutritional value of Urochloa brizantha 'Marandu' at different locations within the pasture in silvopastoral system, Tosta et al (2015) also found no differences in fiber concentrations (mean 73.3% NDF). Oliveira et al (2017) found similar results in Urochloa brizantha 'Marandu" and Panicum maximum 'Mombaça' within systems with 0.25 and 50% of natural shading (averages of 62.7 and 63.9% of NDF for Marandu and Mombaça grasses, respectively).…”

“…The knowledge about forage characteristics which are influenced by animal grazing in different production systems is essential, since the environmental conditions to which grasses are exposed affect their morphophysiological traits and nutritional responses (Oliveira, Santos, André, Santos, & Oliveira, 2017;Guimarães, Ribeiro, Viana, Pereira, & Santos, 2018;Faria, Morenz, Paciullo, Lopes, & Gomide, 2018), which are directly related to animal performance in grazing systems.…”

To evaluate the bromatological composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Xaraés palisade grass (Urochloa brizantha ‘Xaraes’ syn Brachiaria brizantha) under grazing in integrated crop, livestock (ICL), and forest (ICLF) systems, we conducted an in situ degradability trial in randomized blocks with three non-lactating 3/4 Gyr × 1/4 Holstein cows, provided with ruminal cannula. The management of Xaraés palisade grass was similar in both systems, differing only regarding shading in the ICLF system provided by eucalyptus trees (average 65% crown cover). Grass samples were incubated for 0, 3, 6, 9, 12, 24, 36, 48, 72, and 96 hours. Considering the passage rate 2% h-1, the Xaraés palisade grass of ICL system had greater NDF effective degradability in relation to ICLF (46.38% vs 44.98%). However, the palisade grass CP potential degradability was greater in the ICLF than in the ICL system (68.92% vs. 65.40%). The presence of trees in the pasture has effect on nutritional traits of the Xaraés palisade grass, increasing its protein content and degradability and reducing its fiber degradability.

“…The monoculture system differed statistically from the SSP system in relation to the number of tillers/m 2 (Table 4), with a larger number of tillers in monoculture regardless the cutting height in the rainy season, reaching 50% of the number of tillers in relation to SSP. The number of tillers is directly related to forage DM production, which is strongly influenced by natural shading, since it modifies the red: far-red ratio of the incident radiation, directly affecting the quality and quantity of light (Oliveira et al, 2017), altering the density of tillers per area in shady environments and affecting the appearance of new tillers (Paciullo et al, 2008). The smallest number of plants in SSP is directly related to the quantity and quality of the luminosity that enters the forest, where the patterns of growth and appearance of tillers in this type of system also affects the lifespan of the plant.…”

“…The grasses of the genus Megathyrsus maximus, cv Mombasa, have shown production in silvopastoral systems similar to pasture in full sun, proving to be a grass with high capacity to shading adaptation, reaching high levels of dry mass production in shady systems (Oliveira et al, 2017).…”

This study aimed to evaluate the production of Mombasa grass cultivation under two different systems: monoculture and silvopastoral, with heights of 70, 80, 90, and 100 cm. Two seasons were evaluated: rainy period (December to March) and rain/drought transition (March to June). The variables evaluated were: total dry mass (TDM), dry mass (DM) of the morphological components, number of tillers, efficiency of nitrogen use, DM content, number of harvest cycles and cutting intervals. The experimental design was a randomized block design with five replications. The monoculture system presented the highest yields of TDM, number of tillers and DM of the morphological components in the two evaluated periods. The main variable affected by shading was the number of tillers per area, which directly affects all variables linked to production. In addition to the type of system, the time of the year also influenced the production of DM of the grass. The evaluation of grass productivity in silvopastoral system evidenced that the plant tends to respond differently to cutting management when compared to the monoculture system. In the monoculture system, the recommended height for greater TDM yield and better leaf/stem ratio in the rainy period and the rainy/drought transition period was 80 cm, maintaining the residue height at 40 cm. As for SSP, cutting height of 70 cm presented the highest TDM and leaf/stem ratio for the two evaluated periods, maintaining the residue height at 40 cm.

“…The shaded environment provided LApR of 11.45% higher than the full sun (0.106 and 0.1197 leaf tiller -1 day -1 , full and shaded environments, respectively considering the overall mean of LApR). The rate of leaf appearance is a function of genotype and the influence of environmental factors, so the increase in the appearance of new leaves under shade is a result of the effects of Mombasa grass adaptation to this type of environment (OLIVEIRA et al, 2017). Masturcello et al (2015) found similar results for leaf appearance rate.…”

The objective of this work was to evaluate the effects promoted by full sun and natural shading (25%) enviroemnts , under the productive components of Panicum maximum cv. Mombasa grown in diferent levels of nitrogen (0, 25, 50, 100 kg ha-1 cycle-1 ). Urea was used as nitrogen source, applied on the surface. This study evaluated the following variables: number of total leaves (NTL), number of green leaves (NGL), number of dead leaves (NDL), leaf lifespan (LLS), sheath length (SL), stem elongation rate (SER), Phyllochron (PHYL), leaf appearance rate (LApR), leaf elongation rate (LElR), leaf senescence rate (LSR), average length of leaf blade (ALLB), leaf area index (LAI) and tiller population density (TPP). The shaded environment provided better conditions for sheath length and leaf elongation rate, however in full sun the tiller density was higher.
