Productive potential of grass Mombasa fertilized doses with different nitrogen - year II

Pastures have an important role in the Brazilian scene in the production of meat and milk, among which stands out the grass Mombasa, which is characterized by its great productive potential. The aim of this study was to characterize the Mombasa grass productivity in Paranaense Southwest fertilized with different doses of nitrogen throughout the growing cycle. We used the design in blocks with 4 levels of nitrogen (N), 0, 120, 240, 360 kg / ha / year with three repetitions each. The nitrogen source used was a 45% urea. They were made five cuts with a mean interval of 44 days between cuts. Nitrogen fertilization was parceled after each cut, except for the last sentence. A positive interference of N in all morphological components of the plant. The average production for MS 0 dose was equal to 4795 kg / ha / year and a dose of 360 kg of N equal to 17,801 kg / ha / year. The DM yield of above 0.3 meters? leaves was 3,827, 7,977, 11,304, 14,305 kg / ha / year for doses 0, 120, 240, 360 kg N / ha, respectively. The average intake time was 82 cm. According to the climatic variables, it was observed that the higher productivity is found in the summer period and the lowest production in the spring period.As pastagens t?m papel importante no cen?rio brasileiro na produ??o de carnes e leite, dentre elas se destaca o Capim Momba?a, que ? caracterizado pelo seu grande potencial produtivo. O objetivo desta pesquisa foi caracterizar a produtividade do capim Momba?a no Sudoeste Paranaense fertilizado com diferentes doses de nitrog?nio ao longo do ciclo vegetativo. Foi usado o delineamento em blocos ao acaso com 4 doses de nitrog?nio (N), 0, 120, 240, 360 kg/ha/ano com 3 canteiros de cada dose. A fonte de N utilizada foi a ureia com 45%. Foram feitos 5 cortes com intervalo m?dio de 44 dias entre cortes. A aduba??o nitrogenada foi parcelada ap?s cada corte, excetuando-se o ?ltimo per?odo. Observou-se interfer?ncia positiva do N em todos os componentes morfol?gicos da planta. A produ??o m?dia de MS para dose 0 foi igual a 4.795 kg/ha/ano e com dose de 360 kg de N igual a 17.801 kg/ha/ano. A produ??o de MS de folhas acima de 0,3 metros foi de 3.827, 7.977, 11.304, 14.305 kg/ha/ano para as doses 0, 120, 240, 360 kg/ha de N, respectivamente. A altura m?dia de entrada foi de 82 cm. De acordo com as vari?veis clim?ticas, foi poss?vel observar que a maior produtividade ? encontrada no per?odo do ver?o e a menor produ??o no per?odo de primavera
