Resumo: The experiment was conducted from December/2002 to April/2003, with the objective of evaluating the effects of different phosphate sources (Yoorin&reg; magnesium thermophosphate, Simple Superphosphate + Triple Superphosphate, Gafsa natural phosphate, and control – no phosphate application) as a function of the evaluation months, on leaf area index (LAI), tiller weight (P) and number, percentage of total leaf and stem (%) and leaf blade/stem ratio of Mombaça grass (Panicum maximum Jacq. cv. Mombaça). The experiment design was a randomized block, with three replications. Phosphate sources influenced (p < 0.05) the weight and number of tillers, while Yoorin&reg; had less weight per tiller, and the Gafsa phosphate obtained the lowest number of tillers. There was a period effect (p < 0.05) for all evaluated variables. The lowest LAI was observed in April, and the highest in February, showing adaptation to a new reproductive cycle. There was little phosphorous influence on tillering; however, soluble phosphate increased the weight of tillers, while the period increased leaf presence.

Mombaça). O delineamento experimental utilizado foi em blocos ao acaso com três repetições. As fontes de fósforo influenciaram (p < 0,05) no peso e número de perfilhos, enquanto o Yoorin&reg; proporcionou o menor peso por perfilho; no tratamento Gafsa, houve o menor número de perfilhos. Houve o efeito de período (p < 0,05) para todas variáveis estudadas. O menor IAF foi observado no mês de abril, enquanto o maior foi no mês de fevereiro, mostrando uma adaptação ao início de um novo ciclo reprodutivo. Os resultados mostram que houve pouca influência do fósforo sobre o perfilhamento, contudo, o fosfato solúvel promoveu aumentos de peso dos mesmos, enquanto que os meses propiciaram aumentos das lâminas foliares na pastagem.Editora da Universidade Estadual de Maringá2008-06-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/359310.4025/actascianimsci.v30i1.3593Acta Scientiarum.
