Production season
The 2010-2011 canola production season in Oklahoma was challenging due to wide-spread below normal precipita­tion.
The southwestern part of the state dealt with extreme drought conditions, while the northwest part of the state dealt with less severe drought conditions. However, precipitation was still below normal in most places.
The 2010-2011 winter we experienced was one of our coldest winter in recent times and very little winter kill was observed as long as the planting date was within the recom­mended
time frame. As long as the planting date recommenda­tions
are followed winter kill appears to not be a problem for most areas in Oklahoma when using recommended varieties/hybrids for Oklahoma.
Pest problems
Overall, pest problems were average in 2010-2011. Aphid pressure varied from region to region as usual. In the drier areas pest pressure tended to be greater. False chinch bugs were present in a few locations and had to be controlled.
Interpreting Data
Details of establishment and management of each test are listed in footnotes below the tables. Least significant dif­ferences
(LSD) are listed at the bottom of all but the Perfor­mance
Summary tables. Differences between varieties are significant only if they are equal to or greater than the LSD value. If a given variety out yields another variety by as much or more than the LSD value, then we are 95% sure that the yield difference is real, with only a 5% probability that the dif­ference
is due to chance alone. For example, if variety X is 500 lb/acre higher in yield than variety Y, then this difference is statistically significant if the LSD is 500 or less. If the LSD is 501 or greater, then we are less confident that variety X really is higher yielding than variety Y under the conditions of the test.
The CV value or coefficient of variation, listed at the bot­tom
of each table is used as a measure of the precision of the experiment. Lower CV values will generally relate to lower experimental error in the trial. Uncontrollable or immeasurable variations in soil fertility, soil drainage, and other environmental factors contribute to greater experimental error and higher CV values. Generally, a CV less than 15 for canola trials is considered good. This is an indication that less error was observed in the plots.
Results reported here should be representative of what might occur throughout the state but would be most applicable under environmental and management conditions similar to those of the tests. The relative yields of all forage legume vari­eties
are affected by crop management and by environmental factors including soil type, winter conditions, soil moisture conditions, diseases, and insects.
Methods
Test locations were near Burlingotn, El Reno, Frederick, Fort Cobb, Lahoma, Hunter, Kingfisher, and Stillwater. The location at Frederick, Fort Cobb, and Hunter, OK was lost due to environmental conditions.
Plots were 4 feet wide by 30 feet long and seeded at a rate of 5 lb/ac. Soil characteristics and fertilizer applied is indicated for each location on later pages. Plots were kept pest free for the duration of the growing season. Entire plots were dessicated and harvested with a small plot combine.

Observations:
An excellent stand was achieved in the fall. Plants were four to five leaves going into winter dormancy. Winter survival was excellent. Yields were good given the lack of precipitation since December. Seed yields at Burlington averaged 2,391 lb/ac in the Glyphosate resistant trial and 2,685 lb/ac in the conventional test. Plots were desiccated on May 31 and direct harvested on June 6.

Observations:
An excellent stand was achieved in the fall. Plants were six to seven leaves going into winter dormancy. Winter survival was excellent. Yields were good given the lack of precipitation from Dec. through April. Seed yields at El Reno averaged 1,841 lb/ac in the Glyphosate resistant trial and 2,155 lb/ac in the conventional trial when averaged across all varieties/hybrids. Plots withstood some severe wind during the last week of May but shatter loss was minimal with the exception of DKW41-10. This is a result of the relatively short maturity of this variety compared to the other varieties. Please take this into consideration when viewing results. Plots were desiccated on May 25 and direct harvested on May 31.

Kingfisher, Okla.
Observations:
An excellent stand was achieved in the fall. Plants were six to seven leaves going into winter dormancy. Winter survival was excellent. Yields were good given the lack of precipitation from Dec. through April. Seed yields at Kingfisher averaged 1,481 lb/ac in the Glyphosate resistant trial. Plots withstood some severe wind during the last week of May and a hail event that resulted in shatter loss. The earlier maturing varieties had more shatter since they were more mature. Please take this into consideration when viewing results. Plots were desiccated on May 23 and direct harvested on May 31. No conventional test was harvested at Kingfisher due to herbicide damage.

Observations:
An excellent stand was achieved in the fall. Plants were four to five leaves going into winter dormancy. Winter survival was excellent at Lahoma. Timely rains in the spring increased yield potential even though the winter months were extremely dry. Seed yields at Lahoma averaged 3,529 lb/ac in the Glyphosate resistant trial and 2,918 lb/ac in the conventional trial when averaged across all varieties/hybrids. Insecticide was applied once in the spring. Plots were desiccated on May 31 and direct harvested on June 3.
