Genotypic ranking and repeatability coefficient in elephant grass genotypes for biomass production for energy applications

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Energy demand has become a global bottleneck, and the search for alternative sources is intensifying worldwide. In this context, elephant grass emerges as an excellent alternative due to its high dry matter production capacity coupled with beneficial biomass quality, high fiber content, high C/N ratio, and high calorific value.
