2011 PERFORMANCE TESTS
Statewide Growing Conditions
Objectives and Procedures
The Kansas Agricultural Experiment Station established an
official cotton testing program in 1980 to provide Kansas
growers with unbiased performance comparisons of cotton
varieties marketed in the state. Companies enter varieties of
their choice and pay entry fees to cover part of the costs of
conducting the tests.
Descriptive information is presented with the results for
each test. This information, including soil type,
establishment methods, irrigation, harvest dates, and
growing conditions unique to that location, can help explain
test and/or variety performance.
In addition to lint yield and the yield as a percentage of test
average, each table includes observations on cotton fiber
quality. Each bale receives a rating on micronaire (Mic),
length, uniformity index, strength, and color grade.
At the bottom of each column, the least significant
difference (LSD) is listed at the 0.05 level. These values
indicate how large of a difference is needed to be confident
that one variety is superior to another. Differences between
varieties that are equal to or greater than the 0.05 LSD have
only a 1 in 20 chance of being due to chance or error.
The coefficient of variability (CV) provides an estimate of
the consistency of the results of a particular test. In these
tests, CV less than 10% generally indicates reliable, uniform
data, whereas CV of 10 to 15% are not uncommon and
generally indicate the data are acceptable for rough
comparisons. Tests with CV greater than 15% still may be
useful, but variety comparisons lack precision.
Weather conditions throughout the cotton growing region in
Kansas, especially south central and southwest, were
dominated by above-normal temperatures and heat unit
accumulations and below-normal precipitation. At the
Stevens County location, in-season precipitation was 1.30
inches — nearly 4 inches below normal — with preseason
precipitation prior to planting significantly below normal as
well. In-season precipitation at the Pratt County site was
approximately 2.15 inches, 3 inches below normal. Due to
these extreme circumstances, dryland trials at Stevens and
Pratt Counties had to be abandoned.
A positive to the heat, however, was the accumulation of
heat units, typically a leading challenge in Kansas cotton
production. All three studies harvested for yield had
cumulative heat unit accumulation significantly above
normal. Although drought stress limited boll number per
plant, the heat units allowed for a higher percentage of
harvestable bolls and had a positive impact on fiber quality.
In scenarios where irrigation was adequate, cotton yields
were quite productive.
Production
Detailed information on planting, fertilizing, weed control,
and disease and insect control can be found in the Cotton
Production in Kansas publication issued by the Kansas State
University Agricultural Experiment Station and Cooperative
Extension Service at:
http://www.ksre.ksu.edu/library/crpsl2/mf1088.pdf.
Harvest Statistics
The November 9 Crops report predicted an 83,000-bale
crop, up 1% from the previous year. Yields averaged 494
pounds per acre, which is significantly down from the
previous high of 787 in 2010. Harvested acreage, at 67,000
acres, is up 17,000 acres from last year (Kansas Agricultural
Statistics Service, Topeka).

Excerpts from the
University Research Policy Agreement with Cooperating Seed Companies
Permission is hereby given to Kansas State University (KSU) to test varieties and/or hybrids designated on the attached entry
forms in the manner indicated in the test announcements. I certify that seed submitted for testing is a true sample of the seed being offered for sale.
I understand that all results from Kansas Crop Performance Tests belong to the University and the public and shall be controlled
by the University so as to produce the greatest benefit to the public. Performance data may be used in the following ways: 1)
Tables may be reproduced in their entirety provided the source is referenced and data are not manipulated or
reinterpreted; 2) Advertising statements by an individual company about the performance of its entries may be made as
long as they are accurate statements about the data as published, with no reference to other companies’ names or cultivars.
In both cases, the following must be included with the reprint or ad citing the appropriate publication number and title:
“See the official Kansas State University Agricultural Experiment Station and Cooperative Extension Service Report of
Progress 1064, ‘2011 Kansas Performance Tests with Cotton Varieties,’ or the Kansas Crop Performance Test website,
