La composición química varió de manera significativa (p&lt; 0.01) a través de los diferentes estados fisiológicos, mientras el contenido de extractivos fue mayor (p&lt; 0.05) en la frecuencia de corte de 150 días (15.1%).

<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The objective of this experiment was to evaluate the production of biomass, chemical composition, proximal analysis, calorific value and bioethanol yield of the maralfalfa grass (Pennisetum glaucum*Pennisetum purpureum) harvested at six cutting frequencies. The highest production of biomass, calorific value and bioethanol yield was found at the cut-off frequency of 180 days with 28.5 Mg MS ha-1; 18.2 MJ kg-1 MS; 6982 L ha-1 of ethanol (p&lt; 0.05), respectively. The ash and volatile matter content was higher (p&lt; 0.05) in the cutoff frequency of 60 and 150 days (9.6% and 77.8%, respectively); while the moisture and fixed carbon content was higher at the cut-off frequency of 30 days (8.4% and 18.4%, respectively). The chemical composition varied significantly (p&lt; 0.01) across the different physiological states, while the extractive content was higher (p&lt; 0.05) in the cutoff frequency of 150 days (15.1%). The biomass yield, chemical composition, calorific value and proximal analysis of the maralfalfa grass allow it to be a good bioenergetic source for the liquid fuel industry.]]></p></abstract>
