The objective of this work was, through a path analysis of seed yield in Paspalumnotatum, to obtain basic information for using in management strategiesto improve seed production and consequently, high natural reseeding and a betterpersistence of the species in the pasture. The following variables were analyzed:number of vegetative tiller, number of reproductive tiller, number of raceme/inflorescence,number of seeds/inflorescence, weight of 1000 seeds and seed yield. The mostcorrelated variable with seed yield was the number of reproductive tiller (r= 0.94), and this occurred because its direct effect. Among the other variables,number of vegetative tiller also had a high correlation coefficient (r = -0.83)and indirect effects on the other components. The number of reproductive tillerseems to be the main characteristic to be considered when searching for a higherseed production in Paspalum notatum.
