Elephant grass has high biomass production, with qualities suitable for conversion into bioenergy, but has long been used exclusively for animal feed and only in recent years has it become an energetic alternative. Therefore, it is necessary to select genotypes with potential for energy production. This study evaluated the effect of five harvest times (8, 12, 16, 20, and 24 weeks) on the yield and chemical composition related to biomass quality through combined polynomial regression analyses of the following elephant grass genotypes: Cubano Pinda, Mercker 86-México, Pusa Napier n°1, Mole de Volta Grande, P-241-Piracicaba, and King Grass. A completely randomized design with three replicates, in a split-plot arrangement, was adopted, including two factors (plots = genotypes, subplots = harvest times). The evaluated variables were whole-plant dry matter yield, in t ha -1 (DMY), percentage of neutral detergent fiber (%NDF), and percentage of acid detergent fiber (%ADF). The elephant-grass genotypes Cubano de Pinda, Mercker 86-México, and P-241-Piracicaba showed a linear first-degree effect as a function of the harvest intervals, indicating that they did not reach their maximum production potential. Genotypes Pusa Napier n°1, Mole de Volta Grande, and King Grass, in turn, had a linear second-degree effect. For the NDF variable, all genotypes showed a significant linear second-degree effect as a function of the harvest intervals, except P-241-Piracicaba, for which no regression was observed. For this genotype, there was a significant linear first-degree effect on the %ADF variable.

“…Genotype yield demonstrates why elephant grass stands out among energy crops [35], and with total possibility of insertion into the Brazilian energy matrix consolidated by the use of sugarcane and eucalyptus, mainly by the amount of biomass produced and the production cycle [2]. [12], evaluating elephant grass cultivars in the Northeast region of Brazil, observed that BRS Canará and Cubano Pinda obtained ADMY ranging from 66.3 to 84.3 ton DM ha -1 year -1 at 6 months of cultivation.…”

The study aimed to evaluate the agronomic characteristics of elephant grass (Pennisetum purpureum Schum.) genotypes on energy production in the combustion form. A randomized block design with 3 repetitions was used. The treatments were arranged in subdivided plots scheme, considering as a plot the genotypes and as subplots, the harvest season. The agronomic characteristics plant height (H), leaf length (LL), leaf blade width (LBW), stem diameter (SD), tillers number (TN), stem percentage (SP), dry matter yield (DMY) were evaluated. The rainy season provided greater H to elephant grass genotypes with height above 3.5 m. The average SP obtained by the genotypes was 68.21% and 67.21% to the first and second year of cultivation, respectively, which gives the biomass good quality of burning. The rainy season provided greater DMY comparing to the dry season. In the first year of cultivation there were genotypes with annual dry matter yield (ADMY) above 50 ton ha-1 year-1, however, the non-maintenance of soil fertility promoted the reduction of 39.17% and 39.05% in the DMY and ADMY, respectively. Analyzing the agronomic characteristics, we conclude that the promising genotypes of elephant grass to produce energy in the form of direct combustion are CNPGL 91-25-1, Cubano Pinda, BRS Canará, Porto Rico and Mercker.

The purpose of this research was to evaluate the behavior per se of elephant grass (Pennisetum purpureum Shum) hybrids for energy purposes by means of morpho-agronomic traits in four evaluation sections. An experiment in randomized block design with three replicates was applied to evaluate the hybrids. The plot consisted of a 15-m row with 1.50-m row spacing, and 1.50-m spacing between plants. The usable area was composed of the five central plants. It was evaluated Number of tillers per clump; Stem diameter; Plant height; Plant dry matter yield; and Percentage of dry matter. Computational resources from the GENES Program were used to analyze the results. In both cuts, the H7, H11, and H14 hybrids was superior to the others in the four evaluation cuts for all evaluated characteristics, proving to be a potential genotype to be used for energy biomass production.
