Effect of nitrogen fertilization on structure and tillering dynamics of Piata palisade grass during the deferment period. Repositório Alice
SOUSA, B. M. de L.; SANTOS, M. E. R.; AMORIM, P. L. de; SILVEIRA, M. C. T. da; ROCHA, G. de O.; CARVALHO, A. N. de.
Nitrogen fertilization can increase the appearance of new tillers, which can improve the structure of deferred sward, since the deferral period is not long. Thus, the objective of this study was to estimate the effects of nitrogen fertilization on structure and tillering dynamics of Piata palisade grass (Brachiaria brizantha cv. Piata) during deferment. We evaluated three nitrogen fertilization levels (none - 0 kg ha -1; medium - 75 kg ha -1; and high - 150 kg ha -1) associated with deferment periods (1, 30, 60, 90, and 120 days). The experimental design was set in completely randomised blocks in a split-plot arrangement, with three replications. The deferment period influenced foliage area index quadratically (p < 0.01) at all fertilization levels. The...

Morphogenesis in guinea grass pastures under rotational grazing strategies. Repositório Alice
MONTAGNER, D. B.; NASCIMENTO JÚNIOR, D. do; SOUSA, B. M. de L.; VILELA, H. H.; SILVEIRA, M. C. T. da; EUCLIDES, V. P. B.; SILVA, S. C. da; CARLOTO, M. N..
This study was conducted in order to evaluate the morphogenetic and structural characteristics of guinea grass cv. Mombasa under three post-grazing heights (intense - 30 cm, lenient - 50 cm and variable - 50 in spring-summer and 30 cm in autumn-winter) when sward light interception reached 95% during regrowth. Post-grazing heights were allocated to experimental units (0.25 ha) in a completely randomized block design with three replications. Post-grazing heights affected only leaf elongation rate and the number of live leaves. Pastures managed with variable post-grazing height showed higher leaf elongation rate in the summer of 2007. This management strategy also resulted in a higher number of live leaves. During the spring of 2006, plants showed lower leaf...

Morphogenetic and structural characteristics of guinea grass pastures submitted to three frequencies and two defoliation severities. Repositório Alice
BARBOSA, R. A.; NASCIMENTO JÚNIOR, D. do; VILELA, H. H; SILVA, S. C. da; EUCLIDES, V. P. B.; SBRISSIA, A. F.; SOUSA, B. M. de L..
It was evaluated the morphogenic and structural characteristics of guinea grass under rotational at three grazing intervals and two defoliation intensities. Grazing intervals corresponded to the time needed by the forage canopy to reach 90, 95 or 100% of incident light interception during regrowth and they were evaluated combined to two defoliation severities (post-grazing conditions, 25 and 50 cm of height), being allocated to experimental units according to a complete randomized design, with three replicates and 3 × 2 factorial arrangement. The experiment was conducted from July 2003 to May 2004. For evaluation of morphogenetic and structural characteristics, ten tillers per experimental unit were selected. Morphogenetic and structural characteristics...

Morphogenetic and structural characteristics of guinea grass tillers at different ages under intermittent stocking. Repositório Alice
BARBOSA, R. A.; NASCIMENTO JÚNIOR, D. do; VILELA, H. H.; SOUSA, B. M. de L.; SILVA, S. C. da; EUCLIDES, V. P. B.; SILVEIRA, M. C. T. da.
The objective of this research was to assess morphogenetic and structural characteristics of tillers of guinea grass cv. Tanzania at different ages. The pastures of guinea grass were managed in six pasture conditions related to the combination of three frequencies (90, 95, and 99% light interception) and two post-grazing heights (25 and 50 cm). In these six pastures conditions, three tiller ages were evaluated (young, mature, and old). The design was of completely randomized block with three replications. Young tillers exhibited higher leaf appearance rate and leaf elongation rate and, consequently, higher final leaf length and number of live leaves than mature and old tillers, regardless of the pasture condition. On pastures managed with 90 or 95% light...

Morphogenetic and structural characteristics of tillers of guinea grass of different age and grazing severities. Repositório Alice
MONTAGNER, D. B.; NASCIMENTO JÚNIOR, D. do; SOUSA, B. M. de L.; VILELA, H. H.; EUCLIDES, V. P. B.; SILVA, S. C. da; SBRISSIA, A. F.; CARLOTO, M. N.
The objective of this research was to evaluate the effects of tiller age on morphogenic and structural characteristics of guinea grass cv. Mombaca subjected to intermittent stocking and three stubble heights: 30 cm, 50 cm and 50-30 cm. Stubble heights were assigned to experimental units in a completely randomized block design with three replicates. Grazing was performed when canopy intercepted 95% of light incidence. Leaf appearance rate, leaf elongation rate and number of live leaves per tiller were higher in the summer when compared with the winter. Contrarily, stem elongation rate, phyllochron and leaf lifespan were lower in the summer when compared with the winter. During the summer, young tillers had higher leaf appearance and elongation rates when...

Tillering dynamics in Guinea grass pastures subjected to management strategies under rotational grazing. Repositório Alice
ZANINE, A. de M.; NASCIMENTO JÚNIOR, D. do; SOUSA, B. M. de L.; SILVEIRA, M. C. T. da; SILVA, W. L. da; SANTOS, M. E. R..
This study was carried out to analyze the tillering profile of Guinea grass (Panicum maximum cv. Tanzania) pastures subjected to two grazing frequencies (time necessary to intercept 90 and 95% of the incoming light) and two post-grazing heights (30 and 50 cm) in the period from November 2005 to October 2006. The experimental design was of completely randomized blocks with three replications, in a 2 × 2 factorial arrangement. At the end of the spring, pastures managed with 90% light interception showed greater tiller appearance rates in relation to pastures managed with 95%, regardless of post-grazing height. In the summer and fall, pastures managed with post-grazing height of 30 cm showed higher tiller appearance rates in comparison with pastures managed...
