This experiment was conducted to estimate the effects of nitrogen fertilization associated with the initial height of the Piata palisade grass on the number and structural characteristics of individual tillers after the deferment period. An area with Brachiaria brizantha cv. Piata measuring approximately 288 m2 was used. Combinations of levels of nitrogen fertilization (0, 75 and 150 kg/ha of nitrogen) and initial heights of the sward (low – 20 cm, medium – 30 cm and high – 40 cm) were […]

The biomass flow of Panicum maximum cv. Tanzania under intermittent stocking with four concentrate supplementation levels, with three grazing periods and 21 rest periods was evaluated. A split plot design, with supplementation level (0.0, 0.6, 1.2 and 1.8% of live weight) and grazing cycles as sub-parcels, with three replicates (paddocks) by treatment was used. There was no effect between supplementation levels and grazing cycles on the leaves 1 and 2 TAlF ratio, averaging 0.69. There was a square effect of […]

This work aimed to evaluate the tilling and tiller structural characteristics on Brachiaria decumbens cv. Basilisk pasture fertilized with nitrogen (N) under different deferring periods. The treatments had 73, 95 and 116-day deferring periods, and 0, 40, 80 and 120 kg/ha N doses. A randomized block design with three replicates and subdivided plots was used. The number of vegetative tillers (VT) reduced as the deferring period increased. Interaction between the deferring period and N doses on the VT population density […]

This research evaluated the canopy structure of tanzania grass under intermittent stocking with four concentrate supplementation levels (SL) (0.0; 0.6; 1.2 and, 1.8% of live weight), in a split plot design, with SL being plots and grazing cycles (GC) subplots, with four replicates. Total herbage dry mass (MSFT), death herbage dry mass (MSFM), green herbage dry mass (MSFV), green leaf blade dry mass (MSLV), green stem dry mass (MSCV), canopy height (ALT); number of live leaf per tiller (F/P), leaf/stem […]

The objective of this research was to compare three methods for estimating LAI in marandu palisadegrass (Brachiaria brizantha Hochst. ex A. Rich cv. Marandu) swards subjected to four grazing heights (10, 20, 30 and 40 cm) under continuous stocking by beef cattle. Evaluated methods were: (1) Direct, destructive (LAIDM); (2) Indirect, destructive, based on the use of tiller population density and mean leaf area per tiller (LAITPD); and (3) Indirect, non-destructive, based on the use of a LAI-2000 canopy analyser […]
