2011 WHEAT CROP OVERVIEW
The 2010-2011 wheat production season can be
characterized as record breaking, but not in a positive
sense. The year was marked by record drought,
record cold, and record heat that exacted a toll on the
Oklahoma wheat crop. At the time of writing this
report, 2011 Oklahoma wheat production is estimated
to be approximately 74.8 million bushels or 38% less
than 2010 (Table 1). Lower production was offset to
some extent by higher prices with cash prices at
harvest exceeding $8 per bushel at some locations.
Table 1. Oklahoma statistics for 2010 and 2011
production years
2011 2010
Harvested Acres 3.4 million 3.9 million
Yield (bu/ac) 22 31
Total bushels 74.8 million 120.9 million
Most areas of the state had just enough moisture for
wheat emergence in the fall of 2010. This moisture
was quickly used but never replenished in
southwestern Oklahoma and the western tier of
counties in northern Oklahoma. As a result, early-sown
wheat intended for grazing was parched by mid
winter and never recovered. Most of the fields in this
situation were “zeroed out” for insurance purposes
and not harvested for grain. The same can be said for
a good portion of the dryland wheat in the Oklahoma
Panhandle where drought conditions were
exacerbated by record low temperatures. This was
especially true in Cimarron County where a mere 1.4
inches of precipitation occurred between planting and
wheat maturity. Despite the harsh environmental
conditions wheat at our Keyes test site averaged 22
bu/ac illustrating the benefits of fallow and
confirming that wheat is an amazing plant.
A few light rains and relatively large snowfall events
gave wheat in central and northcentral Oklahoma just
enough moisture to make it through the winter in
good condition. Given the relatively good condition
of the wheat crop in this region during December and
January and the favorable price outlook, most
farmers chose to topdress at average to above-average
rates. The condition of wheat in this area
rapidly deteriorated as February, March, and April
passed without appreciable precipitation, however,
and a large portion of topdress N remained on the soil
surface and unavailable to roots. Rains finally arrived
in northcentral Oklahoma in May and were just in
time to retain at least part of the yield potential
present. These rains only added to the problem of too
much moisture in northeastern Oklahoma where
many growers were forced to aerially apply
herbicides and nitrogen due to waterlogged soil
conditions. Finally, Mother Nature offered a
challenge for central and northcentral Oklahoma
wheat producers in the form of late-May hail storms.
The extent of hail damage is illustrated by the 19
bu/ac average yield at Kingfisher where wheat plots
were estimated to be in the 35 – 45 bu/ac range prior
to the hail event.
Lowest average yield among the OSU wheat variety
test sites was at Gage (9 bu/ac) where plots were
grazed during the winter and inadequate moisture
was available for recovery after grazing. Grazing
reduced grain yield of wheat by an average of 12
bu/ac at our Marshall site. Highest average yield was
at the McLoud site (48 bu/ac), which was sown after
a full-season corn crop in a corn/wheat/double-crop
soybean rotation. Drought combined with heat during
grain fill can frequently result in shriveled seed, but
this was not the case in 2011. Test weights were
generally 60 lb/bu or greater in early-harvested wheat
but decreased slightly in later-harvested wheat.
Application of a foliar fungicide had no effect on
average grain yield at Apache or Lahoma. This was
not surprising, as very little foliar disease was present
during the 2010-2011 production year. The most
frequently observed disease of wheat in 2011 was
barley yellow dwarf virus, which is transmitted by
aphids. Infection probably occurred as a result of a
late-winter or early-spring infestation of aphids and
symptoms typically included purpling and yellowing
but not stunting. In addition to barley yellow dwarf,
there were a few reports of wheat streak mosaic virus
and high plains virus in the Oklahoma Panhandle.
While weeds were a problem, reports of excessive
dockage and foreign material were not as widespread
as in 2010. This was probably due to multiple factors,
not the least of which was greater emphasis on wheat
quality by grain elevator managers. It was made clear
in 2010 that stricter dockage and foreign material
standards would be in place for 2011 and most
growers heeded the warning by placing greater
emphasis on timely and accurate weed control.

Methods
Cultural Practices. Conventional plots were eight
rows wide with six-inch row spacing. No-till plots
were seven rows wide with 7.5-inch row spacing.
Plots were 20 feet long and wheel tracks were
included in the plot area for yield calculation.
Conventional till plots received 50 lb/ac of 18-46-0
in-furrow at planting. No-till plots received 5 gal/ac
of 10-34-0 at planting. The Apache, El Reno,
Marshall dual-purpose (DP) trials were sown at 120
lb/ac. All other locations were sown at 60 lb/ac.
Grazing pressure, nitrogen fertilization, and insect
and weed control decisions were made on a location-by-
location basis and reflect standard management
practices for the area.

Introduction
Fall forage production potential is just one consideration
in deciding which wheat variety to plant. Dual-purpose wheat
producers, for example, may find varietal characteristics such
as grain yield after grazing and disease resistance to be a more
important selection criteria than slight advantages in forage
production potential. Forage-only producers might place more
importance on planting an awnless wheat variety or one that
germinates readily in hot soil conditions. Ultimately, fall for-age
production is generally not the most important selection
criteria used by Oklahoma wheat growers, but it is one that
should be considered.
Fall forage production by winter wheat is determined by
genetic potential, management, and environmental factors. The
purpose of this publication is to quantify some of the genetic
differences in forage production potential and grazing duration
among the most popular wheat varieties grown in Oklahoma.
Management factors such as planting date, seeding rate,
and soil fertility are very influential, and are frequently more
important than variety in determining forage production. En-vironmental
factors such as rainfall and temperature also play
a heavy role in dictating how much fall forage is produced. All
of these factors along with yield potential after grazing and the
individual producer’s preferences will determine which wheat
variety is best suited for a particular field.
Site Descriptions and Methods
The objective of the fall forage variety trials is to give
producers an indication of the fall forage production ability
of wheat varieties commonly grown throughout the state of
Oklahoma. The forage trials are conducted under the umbrella
of the Oklahoma State University Small Grains Variety Per-formance
Tests at our El Reno and Stillwater, OK test sites.
Weather data for these two sites are provided in Figure 1.
A randomized complete block design with four replica-tions
was used at each site. Forage was measured by hand
clipping two 1-m by 1-row samples at random sites within
each plot. Samples were then placed in a forced-air dryer for
approximately seven days and weighed. All plots were sown
at 120 lb/A in a conventionally-tilled seedbed and received 50
lb/ac of 18-46-0 in furrow at planting. Fertility, planting date,
and harvest date information are provided in Table 1.

Results
The 2010-2011 wheat production season will undoubt-edly
go down as one of the driest, if not the driest, in Okla-homa
history. While many areas of the state never received
sufficient rainfall for uniform wheat germination, our two test
sites received a timely rainfall in September which allowed
for uniform germination and emergence of test plots (Figure
1). This was followed by two very timely one-inch plus rainfall
events in October and November that allowed for ample forage

production. This was not the case in many areas of Oklahoma
where early-season drought prevented fall forage production
from reaching the 1,000 lb/ac mark.
Forage yields at both sites were outstanding in 2010, and
all varieties produced greater than 2,000 lb/ac of forage by
early December (Tables 2 and 3). There were a large number
of varieties in the top statistical grouping for forage yield (i.e.
all varieties within this group produced statistically-equivalent
forage yield) at both sites. In fact, only four cultivars (Mace,
Shocker, Everest, and Jagger) fell outside of the top statisti-cal
grouping for forage yield in 2010 at Stillwater. The top
grouping at El Reno included more than 50 percent of the
cultivars tested. A similar trend was observed for the two-year
forage averages at both sites with most varieties producing
statistically-equal forage yields by early December.
There is greater separation among varieties when three-and
four-year forage yields are considered and some consistent
top performers such as Fannin, Duster, and OK Bullet can be
identified. This is not to say that some of the newer varieties
cannot produce forage yields equal to or greater than these
three varieties, and rankings could change as we have more
data on newer varieties. Three- and four-year variety com-parisons,
however, are extremely valuable in evaluating the
stability of forage production over a range of environments.

As mentioned in the introduction, fall forage production
is only one parameter to be considered when choosing a
dual-purpose wheat variety. Date of first hollow stem, for
example, will determine how long fall forage production can
be utilized into the spring and should be considered in con-junction
with fall forage production. Varieties such as TAM
401 and Fannin are outstanding forage producers but also
have very early date of first hollow stem. Varieties such as
Doans and Endurance are not consistently as good of forage
producers as TAM 401 and Fannin but are above-average
forage producers and much later to first hollow stem. Dual-purpose
producers should consider these two parameters
in conjunction with grain yield after grazing before making a
variety choice.
First hollow stem data are reported in ‘day of year’ (day)
format. To provide reference, keep in mind that March 1 is day
60 (except for leap years). Average occurrence of first hollow
stem at Stillwater and El Reno in 2011 was day 63 and 64,
respectively. This was approximately one week earlier than
average occurrence of first hollow stem in 2010, and was
probably a result of warmer temperatures combined with
drought stress. There was a 29-day range in occurrence of
first hollow stem at Stillwater and a 24-day range at El Reno.
Environment plays a role in occurrence of first hollow stem,
