Forage
legumes, such as non-creeping alfalfas and traditional clovers,
do not live long in pastures. Kura clover is the most persistent
legume that is currently available. Unlike other clovers or non-creeping
alfalfas, Kura clover spreads by rhizomes or underground stems,
similar to quack grass. This allows the plant to propagate itself
vegetatively and spread one to two feet per year in mixed grass
pastures filling in the bare spots. Kura's ability to survive in
pastures longer than alfalfa may outweigh its lower forage yield,
which is 20 percent less than alfalfa.
Establishing Kura clover is challenging. The plants
remain small the first year because they put so much energy into
establishing taproots and rhizomes. Strategic grazing or
frequent clipping must be used during the first year to
reduce competition from grass and weeds. Do not plant Kura clover
with red clover or other competitive crops during establishment.
Kura clover is compatible in mixtures with Kentucky bluegrass, orchard
grass and smooth brome grass after the establishment year. The persistence
of Kura clover is a large enough benefit that it makes up for the
high establishment costs.
As with other legumes, Kura clover contributes
nitrogen to the pastures system. Mixtures of Kura clover and grass
can yield 50 to 200 percent more than a grass only pasture.
