Composição químico-bromatológica e produtividade do capim-mombaça cultivado em diferentes lâminas de efluente do tratamento primário de esgoto sanitário

Abstract: Chemical-bromatological composition and productivity of Mombaça grass (Panicum maximum cv. mombaca) submitted to different primary wastewater treatments of sanitary sewageIn order to assess possible changes in productivity and chemical composition of the Mombaça grass when subjected to different depths of effluent from primary treatment of sewage (PWTE), we conducted an experiment in a randomized design, consisting of five treatments with four replicates. Plots planted with mombaça grass received different dos… Show more

“…In addition, relatively low rates of nitrogen (E1) reduced biomass yield by up to 84.2% compared with the maximum rates (E5). During this season, biomass yield did not reach the minimal level for cattle grazing, which is 1,200 kg ha -1 (Silva et al, 2012), within the 28-day intervals. This yield drop is associated with low temperatures, humidity and light, which are limiting factors for grass development, unlike what is observed in summer and spring.…”

“…TSW is rich in macro and micronutrients essential for the growth of most crops, making its use convenient in farming (Bertoncini, 2008;Oliveira Filho et al, 2011;Silva, Matos, Borges, & Previero, 2012;Nogueira et al, 2013;Pinto, Cruz, Frigo, Frigo, & Hermes, 2013). Additionally, it also provides an increase in irrigated areas, even in those under jeopardized water use conditions (river basins under critical conditions).…”

“…Esta variação de produção revela a importância da fertirrigação sobre o capim Aruana com vinhaça, corroborando com os dados de SILVA et al (2013) que em estudo com aplicação de vinhaça constataram tanto no período chuvoso quanto no seco efeito significativo nos parâmetros relacionados ao desenvolvimento vegetativo de pastagem.. Já no trabalho de BASSO et al (2013) que ao pesquisarem a resposta da sucessão aveia-preta/milho-silagem/milho mediante a aplicação de vinhaça como fonte de potássio, observaram que a matéria seca da aveia preta, apresentou maior produtividade com a utilização de 100 m 3 ha -1 de vinhaça. SILVA et al (2012) verificaram que a produtividade do capim Mombaça aumentou com as doses de efluente de tratamento primário de esgoto sanitário aplicadas e com a idade de corte. Já CABRAL et al (2011) em estudo com doses de água residuária de suinocultura em capim Elefante não observaram alteração significativa em relação à altura das plantas, massa verde e massa seca, entre as diferentes doses e o tratamento que recebeu apenas água de abastecimento.…”

“…Even with the observed advantages of using these waters, the presence of elements such as excess sodium is a limiting factor for the agricultural use (Silva et al, 2012). Studies highlight this element due to the increments in the exchangeable and soluble contents as well as in the values of the sodium adsorption ratio directly reflecting the electrical conductivity of the saturation extract (Azevedo et al, 2013;Aragüés et al, 2014;Urbano et al, 2017).…”
