Kura clover (Trifolium ambiguum M. Bieb.) is slow to establish and
has low seed yields the year after establishment. Intercropping a cereal
grain during clover seed field establishment could provide additional
revenue to seed growers, provided that intercropping did not jeopardize
future clover seed yields. Factorial combinations of spring- and fall-planted
kura clover monocultured, companion-intercropped with wheat (Triticum
aestivum L.) at two row widths, and relay-intercropped with wheat at two row
widths were compared. Spring-planted clover established better than fall-planted
clover as measured by percent ground cover. Both spring- and fall-planted
kura clover were better established when relay-intercropped than
when companion-intercropped. Spring-planted kura clover relay intercropped
with fall wheat established better than any other treatment
combinations, comparing favorably with spring-planted kura clover
monocultures at 18 months from planting. Kura clover generally did not
affect wheat yields. Wide and narrow row spaced wheat generally affected
kura clover similarly, with narrow-spaced wheat out yielding wide-spaced
wheat. It was concluded that relay-intercropping fall wheat into spring-planted
clover does not adversely affect clover establishment and could
therefore provide more cash revenue than monocultured clover during the
clover establishment period. / Graduation date: 1991
