3 000 COLORADO SUNFLOWER PERFORMANCE TRIALS Introduction In ten short years sunflower have become an important crop in eastern Colorado with acreage surpassing a record 300,000 acres in 999 and a crop value of over $30 million. Statewide, sunflower for oil accounted for over $7 million and confection sunflower production was valued at $3 million. Colorado acreage in 000 planted to sunflower is estimated to be 75,000 acres and approximately $.3 million was spent by Colorado sunflower producers on hybrid seed to plant this acreage. assist Colorado sunflower producers to make the best seed decision, CSU personnel evaluate commercial sunflower hybrids at different locations in northeastern Colorado. The 000 Cropping Season The results of our 000 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 000 irrigated sunflower trial was moved from Bethune to four miles north of Burlington this year. The two locations are approximately 5 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 planted at 9,000 seeds/acre under dryland conditions and at 4,000 seeds/acre under irrigation. Confection hybrids were planted at 5,000 seeds/acre under dryland conditions and at 7,000 seeds/acre under irrigation. Seed yields are reported in pounds per acre adjusted to 0% moisture content. The least significant difference (LSD) value, alpha=0.30, is reported for yield.
