Giant No-till Crops, Yielder dryland wheat Making Big Crops.
The land has an old friend over two generations.

A 1984 Yielder seeding winter wheat on Chemfallow and also applying Aqua Ammonia and dry 16-20-0-14S deep banded between paired row of 8/12.  

The deep bander is an offset leading double disc that penetrates to 5 inches with about ˝ the force required of a double disc.  The Offset Double Disc deep bander disturbs the soil but seems to produce great No-tillage results.  

Each tool bar operates two seed openers and 1 deep bander. Nine tool bars on this 15 foot machine.  The deep bander can also be used as a seed opener.  

High machine availability for 33 crop years.  Serial number 480, the 80th machine built in 1984, went to the Dayton Conservation District in 1984.   

Roger Pennell has three Yielders. Steptoe Butte provides a unique landscape shot. Whitman County’s non-volcano.

Hard to believe how powerful this machine has been in making yields up to 165 bushels per acre average in dryland wheat production.

Pat McConnel, Waitsburg, Washington, produced the highest 165 bu. per acre average yields with this machine design.

Steptoe Butte, 3 miles direct via the Red Tail Hawk and 1,300 feet higher.

Chemfallow seeding Oct. 6, 17, Roger Pennell. Dry Creek Road. Steptoe Butte, Garfield, Palouse, Col. triangle along the Palouse River.

We will come back in about a month for a great shot of paired rows of 2 and 3 leaf winter wheat.

The Roger Pennell Yielder, 1515, NH3 machine is paired row 5/10 or a 15 inch band 7.5 inch machine used in spring cropping.

Pick your weapon.


Paired Row 8/12, 20 inch band centers, average 10 inch.
Allows highest level of P uptake and more off row light to the crop rows.

Fungicides are not often required because the canopy is open with big soft white wheat heads. Big fat kernels at 8,000 per lb.

Paired row, 8/12, each seed row is 4 inches away from the band. 6/12 is optimum with an 1818.

Paired Row 6/12 is 3 inches to the side of the band and allows cereal root access with no seed row fertilizer.

The power play is No-tillage and highest levels of nutrient efficiency.

A fill up of seed in stainless steel boxes. Seed enough for 35 acres at the 100 lb. per acre rate.

Dennis is the curator of the Yielder.

Dry Fertilizer, built in Trail, BC and Pocatello, Idaho, 16-20-0-14S, a very good material. Dry Phosphate source, Keeps costs low….a close competitor to 10-34-0 and 12-0-0-26S. Micros are the advantage of liquids and accurate band rate of TAPPS and TAPPKTS formulation.

The last Yielder drills built in the 90’s were liquid machines due to high flexibility and high crop available nutrients. 

Uniform application became well understood when Yielder drills raised the yield mark again with liquids.

Roger has his white gloves on. He is the man and at the peak of his farming career. His son-in-law is ready to farm. His son-in-law likes the plow, but this will change.

Aqua Ammonia at 20-0-0,
a big flow at 1.4 lbs. N per gallon, up to 80 gallons per acre. About 30 to 40 gallons per acre in this rainfall, good enough to raise 135 bushel average soft white winter wheat.

Aqua Ammonia is NH3 saturated in water. It is just as safety oriented as NH3. Meant only for experienced operators. An escape from research machines. Seldom used outside of the Pacific Northwest.

Aqua Ammonia is base line companion in the development of Exactrix Liquid Injection of NH3. Takes 3 times more gallons of Aqua Ammonia.with the only advantage being Uniformity and shallower placement.

“Mort set his Aqua equipped Yielder drill at 80 lbs. N to raise a good crop of winter wheat because he had Aqua. Son Guy set his 5 custom seeding Yielder NH3 drills at 120 lbs. N to raise a good crop of winter wheat.” 

That means the old fashioned Raven, John Blue, etc. Ammonia systems wasted every third tank of ammonia.

Rodger the Dodger, a good athlete and he likes his college, WSC, woops WSU, Idaho has always been a University.
Roger likes them both.
