Hello to all...
A few years ago, I read an Agronomy journal article from the late 1940's
which discussed the broadcasting of winter grains immediately following
planting of soybeans as a weed control system. As I recall, the yields were
relatively low (~ 20 bushel to the acre) but the winter grain living mulch
system with no supplementary weed control or suppression of the small grain
had comparable yields to the soybean monoculture with cultivation... I have
a copy of this article in my files back in MD but it should be easy to
track down using Agricola...
I have also read about the use of spring planted annual ryegrass as a weed
suppressing but non-competitive living mulch in warm season row crops. In
the study I read about, a. ryegrass consistently suppressed early weeds but
then succumbed to foliar disease (rust) as the crop canopy closed and
summer temperatures increased.
