Introduction
In ten short years sunflowers have become an important crop in eastern Colorado with acreage surpassing a record 300,000 acres in 1999 and a crop value of over $30 million. Statewide, sunflowers for oil accounted for over $17 million and confection sunflower production was valued at $13 million. Colorado acreage in 2000 planted to sunflowers is estimated to be 175,000 acres and approximately $2.3 million was spent by Colorado sunflower producers on hybrid seed to plant this acreage. To assist Colorado sunflower producers to make the best hybrid sunflower seed decision, CSU personnel evaluate commercial sunflower hybrids at different locations in northeastern Colorado.

The results of our 2000 dryland sunflower oil and confection trials at Akron, Cheyenne Wells, and Wray are shown below. The Haxtun dryland trial was lost to poor emergence resulting from dry planting conditions and followed by mid-summer drought. The 2000 irrigated sunflower trial was moved from Bethune to four miles north of Burlington this year. The two locations are approximately 15 miles apart so the Bethune trial name was kept and results are averaged over two and three years.

A randomized complete block design with three replicates was used for all trials. The center two rows of four row plots (30" spacing between rows and 40' long) were harvested for grain yield. Oil hybrids were seeded at 19,000 seeds/acre under dryland conditions and at 24,000 seeds/acre under irrigation. Confection hybrids were seeded at 15,000 seeds/acre under dryland conditions and at 17,000 seeds/acre under irrigation. Seed yields are reported in pounds per acre adjusted to 10% moisture content. The least significant difference (LSD) value, alpha=0.30, is reported for yield. Oil content has been incorporated into performance table results and confection seed size is provided in a table below each performance results table.
