| ABSTRACT This study evaluated the response of carpet grass to pig slurry fertilization in order to estimate the agronomic efficiency and the plant-available nitrogen (N) of such manure. A field test was conducted during two years, following a randomized block design with six replicates of the treatments: 0, 100, 200, 300, 400 and 500 kg N ha-1 year-1, which resulted in 0, 60, 120, 180, 240 and 300 m3 ha-1 (2008/09), and 0, 42, 84, 126, 168 and 210 m3 ha-1 (2009/10), according to the N content of the pig slurry used in each year. These treatments were compared with ammonium nitrate (200 kg N ha-1 year-1), in order to estimate the plant-available nitrogen of the manure for the pasture. Pig slurry doses increased linearly the dry matter yield. In 2008/2009,... |

| ABSTRACT This study investigated the residual effects of pig slurry (PS) applied to common carpet grass pasture (Axonopus affinis) for two years (September 2008-March 2010) on dry matter yield and forage-nitrogen uptake from October 2010-May 2011. A field experiment was conducted in a randomized complete block design with four replications. The treatments were 102, 204, 306, 408, and 510 m3 ha-1 pig slurry applied for two years; one mineral nitrogen rate (1,250 kg ha-1 ammonium nitrate) for two years; and no nitrogen fertilization (control). The pasture was cut at intervals of 48, 34, 43 and 69 days, which corresponded to 266, 300, 343, and 412 days after the last fertilizer application, respectively. Dry matter yield increased by 398 kg ha-1 for each 100... |

| Este trabalho teve como objetivo avaliar a morfogênese da grama-tapete (Axonopus affinis) adubada durante dois anos com dejeto líquido de suínos (DLS). Na média de dois anos, foram aplicados 0, 51, 102, 153, 204 e 255m³ de DLS ha-1, calculados para prover 0, 100, 200, 300, 400 e 500kg de N/ha/ano, respetivamente. A morfogênese foi avaliada na primavera e verão de 2008-2009 e 2009-2010, considerando-se como temperatura basal 10°C para cálculo da soma térmica no intervalo entre as amostragens. Houve aumento linear no número de perfilhos, taxa de alongamento de perfilhos, taxa de expansão foliar e índice de área foliar em função das doses de DLS. Não houve efeito da adubação na taxa de alongamento de pseudocolmo (0,004cm GD-1), taxa de aparecimento foliar... |

| The morphogenesis of giant missionary grass (Axonopus jesuticus x A. scoparius) was evaluated in this study in response to the application of 0, 40, 80, 120, 160, and 200m³ ha-1year-1 of pig slurry, calculated to provide 0, 100, 200, 300, 400, and 500kg N ha-1year-1, respectively. The experiment was carried out in the field, at Chapecó, Santa Catarina, Brazil, in 2010-2011. The doses were fractioned in four applications, performed after the pasture cuttings, during the growth season of the grass. Morphogenetic evaluations were performed weekly between 10/26/2010 and 12/07/2010 (spring), 12/14/2010 and 01/11/2011 (late spring/early summer), 01/18/2011 and 02/07/2011 (summer), and 02/15/2011 and 03/21/2011 (late summer). The leaf senescence, leaf elongation,... |
