Efeitos da intensidade de corte (10 e 20 cm acima do solo), estadios de crescimento (vegetativo, pre-florescimento e florescimento pleno) e doses de nitrogenio (0,100 e 200 kg/ha) sobre a producao de materia seca, teor e producao de proteina bruta da forragem Panicum maximum Jacq. cv. Gatton, foram estudados em condicoes de campo, no ano de estabelecimento, no periodo de outubro de 1975 a julho de 1976, na Estacao Experimental Agronomica da Faculdade de Agronomia da UFRGS, Guaiba, Rio Grande do Sul. Producao de materia seca, teor e producao de proteina bruta aumentaram linearmente com doses crescentes de nitrogenio. Estadios de crescimento nao afetaram a producao de proteina bruta, mas a producao de materia seca aumentou e o teor de proteina diminuiu significativamente com o avanco da idade da planta. O corte baixo resultou em producoes de materia seca e de proteina bruta significativamente maiores que o corte alto, mas o teor proteico da forragem nao foi afetado pela intensidade de corte. Melhores resultados, em termos quantitativos e qualitativos, foram obtidos com a planta colhida no estadio de pre-florescimento a 10 cm acima do solo e com 200 kg/ha de nitrogenio. |

Enteric viruses are present in aquatic environments due to contamination by raw sewage, even in the absence of fecal coliforms, which are considered to be significant indicators when it comes to microbial water quality assessment. This study investigated the presence of group A rotavirus (RVA) in surface water from a river basin in Minas Gerais, Brazil, assessing the influence of the urbanization, the rainfall, and the microbiological and physico-chemical parameters regarding water quality. Forty-eight surface water samples collected in urbanized and non-urbanized areas, both in dry and rainy periods, were obtained throughout the study. The viral particles were concentrated by adsorption-elution in a negatively charged membrane. Fecal coliforms, as well as physico-chemical water parameters were determined at each point in all collections. The RVA was detected in 62.5 % (30/48) of the water samples through a real-time PCR assay. All the sequenced RVA strains belonged to genotype I1. The RVA was detected in 50.0 % (11/22) of the water samples regarded as being acceptable by current microbiological standards. The presence of the RVA and the viral load were influenced by the collection area (p < 0.05). It was also observed a significant association between the RVA and detecting the turbidity of water (p < 0.05). The collected data showed a high level of contamination in this watershed by the discharge of raw sewage, highlighting the need for urgent measures to improve water quality, ensuring the safe use of this matrix.
