“…These values were similar to those found by Oliveira et al (2014), who used the same genotypes used in the current study and observed variation from 27.38 to 47.70 t ha , were similar to or higher than the outcomes found by Oliveira et al (2015a). They worked with 6 elephant grass genotypes grown under increasing N doses (cut at 9 month old) in Campos dos Goytacazes -RJ, Brazil and found mean PMS values varying from 17.61 to 57.65 t ha -1 .…”

Similar to many other human activities, the energy sector has a global concern with environmental issues. The use of renewable energy sources such as biomass is an alternative to the use of fossil fuels. Eight elephant grass genotypes showing energy production potential were herein assessed. The genotypes were grown from February 2014 to March 2016 in Campos dos Goytacazes County -Rio de Janeiro State, Brazil. They were fertilized with three different nitrogen doses (400, 1000 and 1600 kg N ha ) was enough to promote the highest values. As for the other traits assessed in the current study, although there was a genotype that showed statistically significant difference from any other genotype at a particular dose, the increasing N doses in the fertilization did not influence the performance of the genotypes.

“…They found mean DMR 24.8%, values ranging from 23.29 to 25.77%. Oliveira et al (2015a) found mean values ranging from 25.77 to 35.36%. These values were corroborated by the present study wherein mean values from 26.75 to 36.63% were found between the two assessment cycles.…”

“…Quanto aos valores dos coeficientes de variação experimental (CVe), também ocorreram alterações, tendo %CIN: porcentagem de cinza; %FDN: porcentagem de fibra em detergente neutro; %FDA: porcentagem de fibra em detergente ácido; %CEL: porcentagem de celulose; %HEM: porcentagem de hemicelulose; %LIG: porcentagem de lignina; CV e: coeficiente de variação experimental; ** significativo a 1% de probabilidade; * significativo a 5% de probabilidade; ns : não significativo pelo Teste F. Oliveira et al (2015) onde a característica %HEM não apresentou diferenças significativas a 5% de probabilidade. Os autores atribuíram esse fato ao coeficiente de variação genético ser mais elevado em relação ao coeficiente de variação experimental nessa característica.…”

RESUMOAlém do uso como forrageira, o capim-elefante vem sendo utilizado como fonte de energia alternativa. Isso se deve pela sua alta capacidade de produção de biomassa. É desejável que essa biomassa tenha alto teor de fibras e baixo de cinzas, por isso há necessidade de se obter materiais genéticos com essas características. Com isso, o objetivo deste trabalho foi avaliar as características químicas dos híbridos de capim-elefante e dos seus genitores para produção de biomassa energética. O experimento foi conduzido na Empresa de Pesquisa Agropecuária do Estado do Rio de Janeiro, localizada em Campos dos Goytacazes, nos anos de 2011 e 2012. Foram efetuados dois cortes onde foram avaliadas: Porcentagem de cinzas (%CIN); fibra de detergente neutro (%FDN) e ácido (%FDA); celulose (%CEL); hemicelulose (%HEM); e lignina (%LIG). O delineamento foi em blocos ao acaso, com três repetições. Os tratamentos foram quatro genitores femininos, quatro genitores masculinos, 16 híbridos obtidos em esquema de cruzamento em dialelo parcial e uma testemunha. As médias foram comparadas pelo teste de Tukey (P < 0,05). Em relação às características avaliadas no presente estudo, as combinações híbridas H1, H3, H5, H7, H9 e os genitores P4 e P6 possuem boas qualidades de biomassa e, com isso, apresentam potencial para uso para fins energéticos. Palavras-chave: bioenergia, cinzas, Pennisetum purpureum Quality biomass in elephant grass hybrids for energy purposes ABSTRACTBesides the use as forage, elephant grass has been used as an alternative energy source. This is due to its high production capacity of biomass. It is desirable that this biomass has high fiber content, low ash, so there need to obtain a genetic material with these traits. Thus, the aim of this study was to evaluate the chemical characteristics of elephant grass hybrids and their parents for the production of energy biomass. The experiment was conducted at Empresa de Pesquisa Agropecuária do Estado do Rio de Janeiro, located in Campos, in the years 2011 and 2012 were made two cuts which were assessed: Percentage of ash (% CIN); neutral detergent fiber (FDN%) and acid (% FDA); cellulose (CEL%); hemicellulose (HEM%); and lignin (% LIG). The design was a randomized block design with three replications. The treatments were four female parents, four male parents, 16 hybrids obtained by crossing scheme partial diallel and a witness. The Means was compared by Tukey test (P <0.05). As for the traits evaluated in this study, the hybrid combinations H1, H3, H5, H7, H9 and parents P4 and P6 have good biomass qualities and, therefore, have the potential for use for energy purposes.

“…Late flowering is a desirable feature in elephant grass genotypes intended for energy production. However, Oliveira et al (2015) observed that this same genotype displayed the highest dry matter yield at higher levels of N fertilization, which is not desirable.…”
