3 Introduction to the 2015 Colorado Spring Crop Variety Performance Trial Results Colorado State University: Jerry J. Johnson, Sally Sauer, Ed Asfeld, Kevin Larson, Brett Pettinger, Mike Bartolo, Kevin Tanabe, Ron Meyer, Merle Vigil, and Kierra Jewell Colorado State University conducts crop variety trials for research-based, unbiased and reliable performance results to help Colorado farmers make good variety decisions. Imagine that thousands of variety planting decisions need to be made every year by Colorado farmers. A variety must be chosen to be planted in each field, in each year. Variety trials are conducted to assist farmers in making each planting decision. Variety trials help breeders screen elite experimental lines for their adaptability to Colorado conditions. Seed companies use results for marketing decisions. Some trials are part of CSU s formal education efforts to train the next generation of the world s plant breeders and agronomists. CSU extension agents and Agriculture Experiment Station personnel use trial results to make variety recommendations to Colorado farmers. There were some very high yielding corn and and sunflower hybrids hybrids in in 2015, 2015, some some of of the the highest highest we we have have ever ever seen seen in in the the irrigated corn and sunflower trials. Also, some very very high high yielding forage forage sorghum sorghum hybrids hybrids were were identified. identified. Selected Selected corn, corn, sunflower, grain sorghum, and and forage sorghum trial trial results results are are featured featured in in the the following following tables. tables.

Some of the trials are conducted on CSU Agricultural Experiment Stations and others in superior farmer fields. We are very thankful to the farmers who host, without recompense, these variety trials. We are humbled by their generosity. Their names are at the bottom of each trial results table. The trials are made possible with funding from seed company entry fees, and a grant from the Colorado Sunflower Administrative Committee. It is important for farmers to recognize the companies that have entered into the state trials. These companies have excellent hybrids adapted to Colorado conditions. We hope these companies will be patronized by farmers and that the companies that are not featured in the following tables are encouraged to enter. 3
