Title

Competition between Schizachyrium scoparium and Prosopis glandulosa

O. W. van Auken; J. K. Bush American Journal of Botany 1988. doi:10.2307/2443997

Other claims from this paper (6)

Intervention effect Mesquite did not significantly reduce grass dry weight.
Association Mesquite root-to-shoot ratio rose nearly threefold with grass density.
Association Grass root-to-shoot ratio rose nearly threefold with grass density.
Association Grass flowering stalk number and length declined with density.
Intervention effect Mesquite caused a slight nonsignificant reduction in grass flowering stalks.
Observation The authors predict low mesquite establishment in dense productive grasslands.

Title

COMPETITION BETWEEN SCHIZACHYRIUM SCOPARIUM AND PROSOPIS GLANDULOSA

O. W. Van Auken; J. K. Bush American Journal of Botany 1988. doi:10.1002/j.1537-2197.1988.tb13501.x

Other claims from this paper (6)

Intervention effect Mesquite did not significantly reduce grass dry weight.
Association Mesquite root to shoot ratio rose almost threefold from the lowest to the highest grass density.
Association Grass root to shoot ratio rose almost threefold from the lowest to the highest grass density.
Association Grass flowering stalk number and length fell as density increased.
Intervention effect Mesquite presence caused a slight, nonsignificant reduction in grass flowering stalk number and length.
Association The authors predict low establishment of mesquite and other woody legumes in high-density, productive grasslands.
