alfalfa, autotoxicity, seeding alfalfa
Alfalfa producers have observed for many years that attempts to re-establish alfalfa into existing alfalfa stands quite frequently result in failure. In recent years, researchers have begun to suspect that established alfalfa plants may produce toxic compounds that reduce or inhibit the germination of new alfalfa seedlings. The purpose of this publication is to summarize sane of the recent research findings and to describe cultural practices that will help insure success when reseeding alfalfa.
