reason planters are desirable in winter wheat country is the use of
Hybrid Winter Canola for money and for fumigant cover.
Winter Canola is a fumigant crop. Hybrid Winter Canola can be also
used as a cover crop when the price is low and corn is a better
choice in the spring.

Guy Swanson discovered that more seed rows of winter wheat were
cumbersome to No-tillage. More rows actually lowered yields in
following crops due to cool and wet soils in the spring. The winter
wheat residue produced was too much on 9 inch rows. Thus No-till
farmers started to burn their stubble.
No-till Drill in the PNW “Old Yeller” was set up at 9 inch row
spacing. The drill was then modified with row cleaners to 18 inch
row spacing producing superior performance in winter wheat. Bigger
heads resulted and the straw to grain ratio was improved. For sure
there was more grain and less straw on 18 inch drilled seed row

“Old Yeller” seeding 18 inch winter wheat
with Duff Scuffers. Duff Scuffers cleared the path for the
offset leading disc openers.
Urea was metered to the side of seed row…and
the Duff Scuffers covered the volatile urea band. The volatile urea
was sitting at the surface and covered with duff.
The relationship of Urea in surface bands to
seed rows was not correct. Dr. Fred Koehler, a WSU fertility
expert proposed banding nutrients below the seed rows to get high
utilization of place nutrients.
This was also a backfire since the nutrients
were too close to germinating seed using the 16 inch spacing HZ
split Packer design of drill with extended seed boots. Dr. Gary
Hyde, WSU was involved in this development of modifying the 16 inch
HZ Split Packer.
As per the picture above. In 1978 the Urea
was above the 18 inch seed row in a concentrated 18 inch band. This
technique was a backfire on steep slopes as gravity allowed mobile
urea to reach the seed row.
The 46-0-0 and 40-0-0-6S Urea and Urea Gold
was able to move downward and to the side and into the seed row and
hurt the germination of both winter and spring wheat.
The is last year for Old Yeller in the Fall
of 1979…Nitrate 34-0-0 had been eliminated in 1978 and now Urea was
questionable for top yields in Winter Wheat.
By the 1980 the first Yielder Pioneer drills
banded nutrients below the seed row and to the side on 7.5 inch
spacing. The Urea bands were typically 4 inches in depth and between
the 7.5 inch rows.
By 1983 the use of Urea was ended with the
Yielder® Drills. Yielder Drills banded nutrients on paired rows
using Aqua Ammonia and Anhydrous Ammonia and 16-20-0-14S in a common
