Influence of Meloidogyne hapla on Alfalfa Yield and Host Population Dynamics.

J W Noling; H Ferris PubMed 1985

Other claims from this paper (10)

Intervention effect Meloidogyne hapla enhanced self-thinning in alfalfa.
Intervention effect M. hapla reduced alfalfa stand density by 62%.
Association Mean plant weights rose 2.59 times faster without M. hapla as stand density declined.
Association Changes in stand density explained 65% of yield variation.
Association Average individual stem weight explained 85% of yield variation.
Intervention effect M. hapla suppressed alfalfa yield.
Association Yield suppression generally increased over time.
Association Yield suppression generally increased with nematode population density.
Mechanism Yield suppression was attributed mainly to declining plant numbers.
Mechanism Yield suppression was also attributed to suppression in individual plant weights.
