EDVAN, R.L. et al. Characteristics of production of buffel grass as function of cutting intensity and frequency. Arch. zootec. [online]. 2011, vol.60, n.232, pp.1281-1289. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922011000400043.

The objective of this experiment was to evaluate morphogenetic and structural characteristics and biomass production of buffel grass as a function of cut intensities and frequencies. A previously established pasture of buffel grass cultivar Molopo was used. Total area was splited in twenty 8 m² experimental unities with 1 m border lines. A split plot scheme was used with plot in factorial scheme 2x2 to combination of two height of cut (60 and 80 cm) and two height post cut (20 and 40 cm). The experimental design was entirely randomized blocks, with five replicates named 2060, 20-80, 40-60, 40-80. There (p<0.05) of treatments for dry matter per cut production and higher values were observed to 20-80 and 40-80. Tillering, leaf/steam ratio, number of alive leafs per tiller and diameter of plant were influenced by (p<0.05) by different management of buffel grass. Leaf appearance ratio and phylocron were not different (p>0.05) between treatments. Cutting frequency and intensities influenced tillering, leaf/ stem ratio and dry matter production for both the cut as to the total.
