Strip Tillage and Fertilizer Placement in Corn
A strip tillage and fertilizer placement trial in corn was initiated
with the support of the Missouri Corn Growers Association. Strip till was
compared to no-till and conventional tillage with anhydrous ammonia, urea
and ESN (stabilized N), P and K with placement in a band, surface applied
or incorporated. First year yield results indicated strip till yields were
equivalent to conventional tillage and nearly 9 bu/A higher than no-till.
Banded P and K gave equal yields to broadcast applications.
Soybean Fungicides: Plant Health and Yield Effects
Dr. Laura Sweets evaluated thirty soybean foliar fungicide treatments
for disease control and yield benefits at HWRC in 2007. Past results have
shown an on again off again benefit to using foliar fungicides for yield
enhancement. Yield results in 2007 showed no significant yield differences
between any of the fungicide treatments and the untreated check. Yields
ranged from 59 to 68 bu/A. No differences were observed in delayed
senescence (stay green ability).
Bermuda grass Winterkill
Ozarka Bermuda grass sprigged in 2004 at HWRC died this past winter.
Two factors contributing to the loss include a hard ice storm in the winter
with an inch of sheet ice covering the plants and the hard spring freeze in
April. Similar results were observed at the Forage Systems Research Center
near Linneus. Based on these observations Bermuda grass may not fit as a
long-term forage or hay type grass for northern Missouri.
Selecting High Yielding Varieties and Hybrids
The statewide and Hundley Whaley sponsored yield trials continue to
show wide variation in yield potential of commercially available soybean
varieties and corn hybrids. In the statewide trial conducted at HWRC, corn
yields ranged from 208 to 125 bu/A. Soybean yields ranged from 65 to 48
bu/A. Try to target your seed selection to the highest yielding numbers
from several testing locations. Trial results are available on the web at
or in paper form at your local extension office.
