Resumo: | The objective of this study was to evaluate the morphogenic and structural characteristics of piatã grass submitted to intermittent stocking and fertilized with phosphorus sources of different solubilities and nitrogen fertilization. The treatments were: control (without phosphate fertilizer application); slow solubility phosphorus source (FNR); fast solubility phosphorus source (FSS) and mixed solubility phosphorus source (FSM), whether or not associated with nitrogen fertilization. Measurements of pre-demarcated tillers were performed to evaluate the structural and morphogenic characteristics of the plants. Data were analyzed according to a randomized block design in a 4 x 2 factorial arrangement within each season. The minimum squared means of phosphate fertilizer treatments were compared with the control treatment by Dunnet test, and among themselves by the "t" test and the means of use or not of nitrogen fertilization were compared to each other by the "t" test at 5 % of significance. Sources containing readily available phosphorus, as in the FSS and FSM treatments, promoted greater leaf and stem elongation, as well as greater number and appearance of leaves, which highlights the importance of phosphorus and nitrogen availability in plant growth and development. confirmed by the increase in leaf elongation rate, leaf appearance and stem elongation. Thus, nitrogen and phosphate fertilizers are alternatives for the persistence and competitiveness of pasture livestock production. Regarding the source, the use of phosphorus sources with mixed solubility provides this nutrient in the short, medium and long term. Keywords: morphogenic characterization; pasture fertilization; pasture production; Urochloa brizantha cv.BRS Piatan. |

Os tratamentos foram: controle (sem aplicação de adubo fosfatado); fonte de fósforo de lenta solubilidade (FNR); fonte de fósforo de rápida solubilidade (FSS) e fonte de fósforo de solubilidade mista (FSM), associados ou não à adubação nitrogenada. Foram realizadas medições de perfilhos pré-demarcados para avaliação das características estruturais e morfogênicas das plantas. Os dados foram analisados segundo um delineamento em blocos casualizados, em arranjo fatorial 4 x 2, dentro de cada estação do ano. As médias por quadrados mínimos dos tratamentos de adubação fosfatada foram comparadas com o tratamento controle pelo teste de Dunnet, e entre si pelo teste "t" e as médias de uso ou não de adubação nitrogenada foram comparadas entre si pelo teste "t" a 5% de significância. As fontes que contém fósforo prontamente disponível, como nos tratamentos FSS e FSM, promoveram maior alongamento de folhas e colmo, bem como maior número e aparecimento de folhas, o que evidencia a importância da disponibilidade de fósforo e nitrogênio no crescimento e desenvolvimento das plantas, confirmado pelo aumento na taxa de alongamento de folhas, do aparecimento foliar e alongamento de colmo. Assim, as adubações nitrogenada e fosfatada são alternativas para a persistência e competitividade da produção animal a pasto. Em relação à fonte, o uso de fontes de fósforo com solubilidade mista fornece esse nutriente a curto, médio e longo prazo.
