Because floral resources affect bee reproduction and mortality of larvae, and
because large numbers of bees are introduced into seed fields, one way to
improve bee yields may be to increase floral resources late in the season.
Planting alternative bloom to increase nectar availability, or to increase
both nectar and pollen late in the season, may improve bee yields. Some
growers already plant buckwheat to provide alternative leaf sources. This
plant also provides additional nectar and pollen. If buckwheat planting is
timed so that it blooms after peak alfalfa bloom, the buckwheat won't
interfere with alfalfa pollination. Clipping or mowing a strip of alfalfa
around the time of bee release to stagger bloom time may also provide flower
resources for the bees, as well as providing a trap crop to attract insect
pests late in the season. (see "clipping options”, slide show 5)
