FERREIRA, D.J.; ZANINE, A.M.; SOUTO, S.M.  and  DIAS, P.F.. Tanzânia grass (Panicum maximum) under shadding and cutting handling. Arch. zootec. [online]. 2010, vol.59, n.225, pp.81-91. ISSN 1885-4494.

Successful silvopastoral systems depend, among other factors, on identifying of grasses tolerant to shading, and knowledge of the pasture management to which they will be submitted. The literature reports separate results on grass, sometimes about the effect of shading and sometimes about the effect of cutting height and interval. The objective of the present research was to study the performance of Panicum maximum cv. Tanzânia, under four shading levels (0, 25, 50 and 75%), two intervals (30 and 60 days) and three cutting heights (15, 25 and 35 cm). A randomized block design in splitplots with three replications was used, the shading levels representing the units and the factorial the cutting intervals and heights, representing subunits. The results of the treatment effects on the variables showed that the treatments in the with greater cutting interval and heights and the lower shading levels provided to more canopy dry matter in the plants, while the greatest interval and shading levels resulted in the biggest values registered for leaf area.

Keywords : Forage management; Cutting intensity; Cutting frequency.
