8 ARKANSAS CORN AND GRAIN SORGHUM PERFORMANCE TESTS D.G. Dombek, 2 R.D. Bond, 3 L. Coffee, 4 and I.L. Eldridge 5 INTRODUCTION Corn and grain sorghum performance tests are conducted each year in Arkansas by the University of Arkansas Division of Agriculture. The tests provide information to companies marketing seed within the state, and aid the Arkansas Cooperative Extension Service in formulating recommendations for producers. The 2005 corn performance tests contained 75 entries and were conducted at the Northeast Research and Extension Center (NEREC) at Keiser, the Lon Mann Cotton Research Station (LMCRS) near Marianna, the Bell Farming Company near Des Arc, the Southeast Research and Extension Center - Rohwer Division (SEREC-RD) near Rohwer, and Queen's Plantation, Inc., near Texarkana, Miller County, Ark. The 2005 grain sorghum performance tests contained 42 entries and were conducted at the NEREC near Keiser, the LMCRS near Marianna, the SEREC-RD near Rohwer, and the Rice Research and Extension Center near Stuttgart. Test location maps for grain sorghum and corn can be found inside the back cover. MATERIALS AND METHODS Corn hybrids were divided into two maturity groups. Based on information provided by the originating companies, entries were placed into a 116-or-fewer-days-to-maturity group or a 117+ group. Within each test, entries were arranged as a randomized complete block design with four replications. Plots were two rows wide and feet long depending on location. Seeding rates for each corn and grain sorghum hybrid were based on the recommendations of the originating company. All plots were harvested with a plot combine. Specific location and management practice information accompany each table. GRAIN SORGHUM PERFORMANCE MEASUREMENTS Yield: Yields were calculated from the weight of threshed grain from each plot and are expressed as pounds per acre (lbs./a) at 14% moisture. Grain Moisture: Expressed as a percent moisture of grain at harvest. Plant Height: Average height in inches from the soil surface to the top of the grain head. Head Exertion: Average distance in inches from the flag leaf to base of panicle. Head Compactness Scale: 1 = Head short and oval. Rachis branches intermediate in length. 2 = Head long and slender. Rachis branches strong and short. 3 = Head elongated and oval. Rachis branches beginning to weaken and intermediate in length. 4 = Head elongated and rectangular in shape. Rachis branches intermediate in strength and length. 5 = Head open and elongated. Rachis branches weak. Bird Damage: A visual estimate of total percent grain loss from each plot. 1Use of products and trade names in this report does not constitute a guarantee or warranty of the products named and does not signify that those products are approved to the exclusion of comparable products. 2 Program Director, Arkansas Agricultural Experiment Station, University of Arkansas, Fayetteville, Ark Program Technician, Department of Crop, Soil & Environmental Sciences, University of Arkansas, Fayetteville, Ark Research Assistant, Department of Crop, Soil & Environmental Sciences, University of Arkansas, Fayetteville, Ark Program Associate, Department of Crop, Soil & Environmental Sciences, University of Arkansas, Fayetteville, Ark

9 CORN PERFORMANCE MEASUREMENTS Yield: Yields were calculated from the weight of shelled corn harvested from each plot and are expressed as bushels per acre (bu./a) at 15.5% moisture. Grain Moisture: Expressed as a percent moisture of shelled grain at harvest. Root Lodging: Average number of plants leaning more than 40 degrees from vertical at harvest. Stalk Lodging: Average number of plants broken below an ear at harvest. Plants/Acre: The plant population count, expressed in the number of plants per acre. Ear Height: The average distance in inches from the soil surface to the point of attachment of upper ear. Test Weight: Test weights, expressed in pounds per bushel (lbs./bu), were determined using subsamples from plots. Tip Cover: Tip cover was rated as good (1), average (2), or poor (3). A rating of good was given when the husks reached well beyond the end of the ear and fitted tightly. A rating of average was given when the husks reached the tip of the ear or fitted loosely. A rating of poor was given when the ears were open to the weather. 7
