3 INTRODUCTION Objectives and Procedures Sunflower performance tests were conducted in 27 by the Kansas Agricultural Experiment Station to provide farmers, extension workers, and private industry with unbiased agronomic information on many of the sunflower hybrids marketed in the state. s were financed in part by entry fees from private companies. Companies known to be developing and marketing sunflowers were invited to participate and enter hybrids on a voluntary fee-entry basis. As a result, not all hybrids grown in the state were included in tests, and hybrids were not grown uniformly at all locations. locations in 27 were Thomas County on fallow; Thomas and Greeley Counties irrigated; and Ellis, Greeley, and Hutchinson Counties dryland. seed entries were grown at all locations. Confectionary entries were evaluated in Thomas County irrigated, and Greeley County irrigated and dryland. The confectionary test at Thomas County dryland was abandoned due to very poor stands. seed and confectionary entries were planted separately in all tests. Entries were planted in four-row, replicated plots at all locations. To ensure uniform and adequate stands, all tests except those in Thomas County were planted at a high seeding rate and were hand thinned after emergence to desired stands. s in Thomas were planted to stand with a modified Monosem Vacuum er. Environmental factors affecting test results and cultural practices are discussed individually for each of the test sites. results for 27 and period-of-years average data are included in Tables 1 through 9. Entrants and entries in 26 tests are listed in Table 1. Data Interpretation s are reported as lbs seed/acre adjusted to 1% moisture content. half bloom is number of days from date of planting to date when 5% of plants were in bloom. percentage is based on counts of lodged and total plants in harvested areas at all locations. percentage was obtained from samples submitted under code number to the Kansas Grain Inspection Service for analysis and is reported on a 1% moisture basis. Samples for all tests were derived by compositing replications by entry for each location and subsampling. yields are reported as net lbs oil/a. -size percentage analysis for confectionary-type entries was performed at the Northwest Research- Extension Center on cleaned samples submitted from each of the tests. Separation by seed size was made by screening a weighed sample through a series of six sieves (22/64, 21/64, 2/64, 19/64, 18/64, and 16/64-round holes) secured on a Ro-Tap mechanical shaker. Statistical analysis: Conducting perfect tests is virtually impossible because soil fertility, moisture, and other environmental factors vary. Therefore, small differences in results might have no real meaning. To help interpret data, we applied a statistical technique, analysis of variance, wherever possible. Such analysis requires repeating whole sets of varieties or treatments several times and placing individual varieties or treatments as they would be placed by chance alone. Results of the analyses are reported in terms of least significant differences (LSD). If two means differ by more than the LSD (.5), such a difference would be due to chance variation only 5% of the time. So, it's 95% probable that the difference was due to treatment. If means do not differ by as much as the LSD, then little confidence can be placed in the importance of varietal or treatment differences. The coefficient of variability (CV) represents an estimate of the precision of replicated yield trials. Trials with a CV ranging from 1 to 15% are usually acceptable for performance comparisons. Trials with a CV greater than 15% provide only a rough guide to hybrid performance. ACKNOWLEDGEMENTS Cooperation of research center personnel who performed many of the field operations is sincerely appreciated. Vicki Brown, secretary, and Jane Lingenfelser, coordinator Kansas Crop Performance s, assisted in preparing this report, and temporary workers Trenton Powell and Katie Friesen helped with seed counting, plot thinning, and maintenance. Mary Knapp at the Weather Data Library provided climatological data, and James R. Cochrane, Assistant Scientist, posted data to the Kansas Crop Performance Web site
