local.description.resumoAimed to evaluate the bromatological composition of different genotypes of elephant grass (Pennisetum purpureum Schum.) to energy production through combustion. The experimental design was a randomized block with 3 repetition and the treatments arranged in a subdivided plots scheme, considering as a plots the thirteen genotypes and harvests (dry and rainy) as subplots. The genotypes evaluated were Cubano Pinda, Porto Rico, Vrukwona, Piracicaba 241, Cuba 116, Taiwan A-25, Mecker, Napier, Canará, Guaçu, Cameroon, CNPGL 93-41-1 and CNPGL 91-25-1 clones. The experiment lasted two consecutive years with harvests made every 6 months, with a harvest in the dry season (September) and another one in the rainy season (March), totaling 4 harvests. For dry matter content analysis, three tillers were selected at random and dried in an oven at 55ºC until reaching a constant mass. For biomass quality analysis, the samples were ground in Willey type mills with 1 mm sieves, submitted to bromatological analysis to determine the neutral detergent fiber, acid detergent fiber, hemicellulose, volatile materials, and fixed carbon content. Higher levels of dry matter (greater than 44.4%), acid detergent fiber (greater than 44.8%), volatile matter (greater than 94.3%) and higher calorific value (greater than 3,450 kcal kg-1) occur in the dry period of the year and in genotypes Mercker, Piracicaba 241, Guaçu and BRS Canará genotypes.
