Use Turnips and other Brassica to multiply your fall and
winter grazing.
_____________________________________________________
If your operation would be able to utilize grazing forage into the fall and
winter after the grasses are no longer available, turnips may be the crop
you should grow. Dr. Bruce Anderson suggests that you have an opportunity to
extend your grazing season into fall and winter using turnips. Turnips
provide good grazing beginning in October that often lasts into the new
year. Also, turnips are cheap to plant since seed can cost less than five
dollars per acre. And now is the time to plant turnips for fall grazing.
Seedbed preparation and planting can be done several ways. Some turnip
growers work soil like a fully prepared alfalfa seedbed. Others heavily disk
their ground, but leave it fairly rough. And a few growers spray Roundup or
Gramoxone on wheat or oat stubble to kill weeds and then plant no-till.
Dr. Anderson suggests that whatever method you choose, good early weed
control is essential. Turnips do poorly if weeds get ahead of them, but once
started, turnips compete very well. Since no herbicides are labeled for
turnips, weeds must be controlled either by tillage or by using contact
herbicides like Roundup or Gramoxone before planting. Then plant quickly to
get the turnips off and running.
Plant only 1 to 3 pounds of turnip seed per acre. Turnip seed is very small,
so barely cover it. If you drill your seed, just scratch the surface with
your openers. Simply broadcasting seed onto tilled soils works well for many
growers, especially on rough seedbeds where rainfall washes soil on to the
seeds for soil coverage. Some producers have had good luck seeding by
airplane into standing corn fields and then using natural rainfall, or pivot
irrigation for seed coveage. Then wait. With a few timely rains you will
have excellent green feed for October, November, and December.
Terry Gompert, UNL Extension Educator notes that there is a difference in
root and top growth between the different types of turnips. On Samples
collected from replicated variety plots grown by Brad Young, the total dry
matter yield varied from 3.9 ton to 4.6 ton per acre.
York Globe turnip produced 5190 lbs of dry matter in the tops and 3930 lbs.
in the root bulbs. Green Globe produced 5691 lbs. in the tops but only 3190
lbs. of dry matter in the roots. Purple Top Turnip produced 4056 lbs of dry
matter in the tops and 3752 lbs in the roots. The Barkant Turnip tops
produced 5129 lbs and the roots 7489 lbs., but because of the smaller size,
only 75% of the root may be available for grazing. The Appin Turnip produced
6866 lbs in the tops with roots at 2067 lbs but only half of that root may
be available to graze. A hybrid Turnip (Pasja) was also included but
produced only 5332 lbs of top, and no roots available for grazing.
Hybrid Brassicas included in the plot were, Winfred with 7571 lbs dry matter
production, Barnapoli at 6707 lbs, Rangiora at 10894 lbs and Dwarf Essex
Rape at 8632 lbs of dry matter.
