Morphogenetical, structural and access to productive buffel grass

Abstract

Although the buffel grass is so important to the productive systems in the semiarid Brazilian studies with this forage are still scarce and diffused, so this experiment was conducted to evaluate the morphogenesis, structural and productive six accessions of buffel grass (Cenchrus ciliaris L.) belonging to the active germplasm bank (BAG) Embrapa semiarid. The experiment was conducted at the Department of Technology and Social Sciences (DTCS) University of Bahia (UNEB), from December 2008 to January 2009. The experimental design was completely randomized with six accessions of buffel grass (Tanzania, Pusa Giant, Aridus, Buchuma, Iran and Biloela) and five replicates, totaling 30 experimental units. Regarding the results, the accessions differed significantly in most variables, especially in morphogenetic and structural variables. It was observed that the buffel grass provides a mean rate of appearance of one sheet every four days in each tiller, with a lifetime of sheet 17 days, keeping ten per tiller. Although they found morphogenetic and structural differences between accessions of buffel grass they did not affect the production parameters.
