Resumo: | This work was carried out in order to obtain subsidies under the definition of strategies for nitrogen fertilization of pastures of tifton 85, based on monitoring the dynamics changes in the structure of swards. The underlying assumption was that the application of increasing levels of N is a powerful tool for that purpose. The experiment was developed over a Planosol of occurrence in the experimental field of the Universidade Federal Rural Rio de Janeiro, city of Serop?dica, Brazil, during the establishment of the pasture, between the months of October, 2006 to January 2007. Treatments consisted of four levels of N (0, 50, 100 and 150 kg N-urea. ha-1), in single application, in plots of 4 x 4 m, arranged in blocks fully randomized, with four repetitions. Together with nitrogen fertilization, the plots received 80 kg P.ha-1 and 150 kg K.ha-1, and Ca as calcareo (1.0 tn.ha-1). The variables were: frequency of occurrence of plants; height of the canopy, leaf growth and leaf area index (LAI), the interception of photosynthetically active radiation (PAR) and the production and partition of dry matter. The results showed that the frequency of occurrence, height and interception of PAR varied according to a standard logistic, whose parameters have been modified to a greater or lesser degree, by the levels of N added. Similarly, at the 87 days after planting, the LAI and the total dry matter produced, but not its partition between leaves and stems, responded to changes in N mineral available in the soil. It was concluded that the application of increasing levels of Nurea, during the establishment of grass tifton 85 was an efficient experimental strategy for the induction of quantitative changes during the development time of swards structure. |

O experimento foi desenvolvido numa ?rea de Planossolo no campo experimental da Universidade Federal Rural do Rio de Janeiro, munic?pio de Serop?dica, RJ, durante a fase de estabelecimento da pastagem, entre os meses de outubro de 2006 a janeiro de 2007. Os tratamentos consistiram de quatro n?veis de N (0; 50; 100 e 150 kg N-ur?ia.ha-1), em aplica??o ?nica, dispostos em parcelas de 4 x 4 m, arranjadas em blocos inteiramente casualizados, com quatro repeti??es. Em conjunto com a aduba??o nitrogenada, as parcelas receberam 80 kg P.ha-1 e 150 kg K.ha-1. O solo foi corrigido com 1,0 tn.ha-1 de calc?reo. As vari?veis estudadas foram: freq??ncia de ocorr?ncia de plantas; altura do dossel, crescimento foliar e ?ndice de ?rea foliar (IAF), intercepta??o de radia??o fotossinteticamente ativa (RFA) e produ??o e parti??o da mat?ria seca. Os resultados obtidos mostraram que a freq??ncia de ocorr?ncia; altura e a intercepta??o de RFA variaram temporalmente de acordo com um padr?o log?stico, cujos par?metros foram modificados, em maior ou menor grau, pelos n?veis de N adicionados. De forma similar, aos 87 dias p?s- plantio, o IAF e a mat?ria seca total produzida, mas n?o a sua parti??o entre folhas e colmos, responderam ?s varia??es do N mineral dispon?vel no solo. Foi conclu?do que a aplica??o de n?veis crescentes de Nur?ia, durante a fase de estabelecimento do capim tifton 85 foi uma estrat?gia experimental eficiente para a indu??o de varia??es quantitativas durante o desenvolvimento temporal da estrutura dos doss?is.Made available in DSpace on 2016-04-28T14:59:45Z (GMT).
