Characterization of Biomass Sorghum Cultivars Aiming to Generate Energy for the North Region of Mato Grosso, Brazil

Abstract

ABSTRACT:Biomass sorghum has high lignocellulosic biomass production, emerging as a cultivation alternative for renewable energy production. The objective of this study was to characterize biomass sorghum cultivars aiming to generate energy for the north of Mato Grosso. To this end, an experiment in the randomized block design with three replications, consisting of 36 sorghum genotypes (34 biomass and two forage) was implanted in 12/04/2014 in Sinop/Mato Grosso. The evaluated characteristics were: flowering, plants height, lodged plants, finishing, plants population, green mass production, dry matter production, dry matter percentage and humidity. Data were subjected to analysis of variance, and the averages of the genotypes were grouped by the Scott-Knott test. Forage materials flourished on average after 77 days, whereas the biomass genotypes flourished from 101 to 130 days. While the best forage genotype (Volumax) produced 11.6 t ha -1 dry matter, 15 genotypes of sorghum biomass produced on average 24 t, each one. Demonstrating being a potential for cultivating in the region. The dry matter produced by biomass sorghum genotypes associated with its calorific has demonstrated the potential of culture for renewable energy production.Keywords: Sorghum bicolor, renewable energy, bioenergy.Caracterização de cultivares de sorgo biomassa visando a geração de energia para a região norte de Mato Grosso RESUMO: O sorgo biomassa possui elevada produção de biomassa lignocelulósica, surgindo como alternativa de cultivo visando produção de energia renovável. O objetivo deste trabalho foi caracterizar cultivares de sorgo biomassa visando a geração de energia para região Norte de MT. Para tal, implantou-se em 04/12/2014, em Sinop-MT, um experimento no delineamento em blocos casualizados, com três repetições, composto por 36 genótipos de sorgo (34 biomassas e 2 forrageiros). As características avaliadas foram: florescimento, altura de plantas, acamamento, população de plantas, produção de massa verde, produção de massa seca, porcentagem de massa seca e umidade. Os dados foram submetidos a análise de variância e as médias dos genótipos foram agrupadas pelo teste de Scott-Knott. Os materiais forrageiros floresceram, em média, aos 77 dias, enquanto que os genótipos de biomassa floresceram dos 101 aos 130 dias. Enquanto o melhor genótipo forrageiro (Volumax) produziu 11,6 t de massa seca ha -1 , 15 genótipos de sorgo biomassa produziram, em média, 24 t. Demonstrando estes serem os de maior interesse de cultivo na região de estudo. A matéria seca produzida pelos genótipos de sorgo biomassa associado a seu poder calorífico demonstram potencial da cultura para produção de energia renovável.Palavras-chave: Sorghum bicolor, energia renovável, bioenergia.Recebido em agosto/2015; Aceito em março/2016.

Correlation and path analysis of biomass sorghum production

“…The genotypes of biomass sorghum differed significantly (P < 0.01) for all traits, demonstrating that there is variability among their genetic constitution ( Table 1). The results were similar to those obtained in other studies (Cunha and Lima, 2010;Tardin et al, 2013;Menezes et al, 2015;Silva et al, 2016). The experimental variation coefficients were normally distributed, demonstrating the accuracy of the experiment, which revealed low values for FLOR (0.59), SD (9.45), NS (4.36), PH (4.20), and NL (4.54), and medium values for GMP (16.09) and DMP (19.32) according to the classification proposed by Gomes (2009).…”

Selecting elephant grass families and progenies to produce bioenergy through mixed models (REML/BLUP)

“…Some plants have shown potential to be used as sources of bioenergy, namely: elephant grass (Daher et al, 2014;Rocha et al, 2015;Salazar-Zeledón et al, 2015;Ghosh, 2016;Menezes et al, 2016), sugarcane (Szczerbowski et al, 2014;Bordonal et al, 2015), sorghum (Silva et al, 2016), and eucalyptus (Eufrade Junior et al, 2016). However, in contrast to elephant grass, which shows high photosynthetic efficiency with high biomass productivity potential, some of these cultures show low dry biomass production.…”
