Trial Objectives and Procedures Each year performance trials for hybrid grain sorghum are conducted by the Oklahoma Cooperative Extension Service. These trials provide producers, extension educators, industry representatives, and researchers with information for grain sorghum hybrids marketed in Oklahoma. Performance trials were conducted at 11 locations in 2017. Dry-land trials were planted at Adams, Apache, Dacoma, Goodwell, Homestead, Keyes, Lahoma, Nardin, and Tipton. One fully sprinkler-irrigated trial and one limited drip-irrigated trial were planted at Goodwell. Yields presented in this document are for the early, medium, and late maturity hybrids for all locations, with the exception of the sprinkler irrigated trial in Goodwell. Early-season rainfall paired with insufficient early season herbicide application resulted in highly variable stands, and therefore had higher variability to yields at the end of the season (Coefficient of Variation greater than 20%). Table 1 lists the hybrids entered in the performance trials. Tables 2 through 30 report hybrid yields and test weights for all trials harvested, with associated populations and head count (on a heads per acre basis) where collected. Grain sorghum hybrids entered (Table 1) were assigned by companies to their respective maturity groups (early = less than 60 days to mid-bloom, medium = 60 to 69 days to mid-bloom, and late = 70 days and greater to mid-bloom) and trial locations; therefore all hybrids were not entered at all locations. Companies designated all hybrid

characteristics presented in Table 1. This information was not determined or verified by Oklahoma State University. Company participation was voluntary, therefore not all hybrids marketed in Oklahoma were included in the trials. In 2017, 45 hybrids were entered by 14 seed companies (Table 1). Among the varieties, 26 were entered as 'sugarcane aphid tolerant'. A separate table appears at the end of this report (Table 31), listing comparative yields between all hybrids considered sugarcane aphid tolerant. Each maturity group was tested independently in a randomized complete block design with four replications. All downstate locations, drip irrigated in Goodwell, and the plots at Adams and Keyes were two row plots with 30” spacing and 25 feet in length. Plots were trimmed to 20 feet prior to harvest. The dry-land trial at Goodwell was two, thirty-inch rows by 35 feet in length and was trimmed to 25 feet prior to harvest. Tractor-powered cone planters were used to plant all trials with seeding rates adjusted for the trial location. Trials were harvested with a Kincaid model, 8XP plot combine in the panhandle and a Wintersteiger Delta combine for all downstate trials. Target populations, cooperating producers, fertilization, cultural practices, soil series, herbicides, and insecticides used in all trials are listed individually in the results tables. Rainfall data from the nearest Mesonet sites are also

listed. Some trials are long distances from the nearest Mesonet site; therefore rainfall could be greater or less than reported. Growing Conditions and Season Highlights

The 2017 season was highlighted by either favorable or challenging conditions at or near planting. For much of the growing season in the Southwest, timely rains and adequate soil moisture was present around planting. This paired with cooler conditions resulted in good emergence of most of the crop. This was not the same found in northcentral and northwest Oklahoma. Most of this region suffered from below normal temperatures and excessive rainfall. This pushed planting dates from April and early-May, typically accepted as the prime planting timeframe, into mid- to late-May. Lower average yields were expected for these locations due to this delayed planting date. The largest impact of the later planting dates can be seen in the Nardin and Homestead location which were not planting until late-May or early-June and therefore had the lowest yields of all the locations. However, the average yields of these locations were not lower than producers around the region in which planting was delayed.

The optimum conditions in the southwest continued throughout much of the season with consistent rainfall, especially during the early and mid-reproductive growth. Therefore, even though many plots in the Southwest locations had thinner stands due to issues at planting, hybrids were allowed to put on an average of 2 heads per plant with good size and density, which resulted in good yields still at both Tipton and Apache. This again differed from the Northwest locations that experienced extended dry conditions throughout much of June, especially later June when the crop was beginning reproductive growth. This resulted in lower average yields.

Late-season conditions resulted in quality dry-down of the crop. All locations received a desiccant application; however, this was conducted as a means to even the crop out and dry-down immature tillers. This desiccation application would not have normally been needed as all plots were weed-free, and maturity was occurring naturally.

Unlike previous years, sugarcane aphids were not a primary pest for most of the sorghum producing regions in Oklahoma. Several localized areas during the season experienced sugarcane aphid populations large enough to trigger an insecticide application, but this was not common throughout the state. The only locations that required an insecticide application were Tipton and Lahoma. Applications at these locations were made prior to the plots reaching the economic threshold. However, two other insect pests did cause concern this season. The first of these was false and true cinch bugs. This pest was primarily in the northern tier of counties in Oklahoma. As there is not an economic threshold and no suitable insecticide is available for control of cinch bugs, many grower’s fields suffered from prolonged exposure to these pests. Sorghum head midge was the other major insect pest issue during 2017. Many growers suffered from

banding of the sorghum head, where part of the sorghum head was absent of grain. No hybrid trial locations experienced issues with sorghum head midge or cinch bugs during the 2017 season; therefore, pest pressure was considered low during 2017. With the exception of the sprinkler irrigated trial at Goodwell, most trial locations did not have any major issues throughout the year. Results Grain yields are reported in pounds per acre and bushels per acre of threshed grain, adjusted to a moisture content of 14 percent (Tables 2 through 31). Test weight is also reported in pounds per bushel. Bird damage is reported when present at a location. Different plant populations at each location prevent accurate comparison between locations. Also, comparisons across maturity were not conducted as they were treated as independent trials. Producers should note that late-maturing hybrids will generally yield more than early and medium maturity hybrids. The availability of moisture at critical crop development periods, however, often influences yield more than the yield differences associated with maturity groups. When choosing a maturity group, the type of cropping system, planting date, planting rate, and potential moisture should be taken into consideration. For more information consult Fact Sheet PSS-2034, Grain Sorghum Planting Rates and Dates, and Fact Sheet PSS-2113 Grain Sorghum Production Calendar. Least Significant Difference (LSD) is a statistical test of yield differences and is shown at the bottom of each table. Unless two hybrids differ by at least the LSD shown, little confidence can be placed in one hybrid being superior to another, and the difference is probably not real.

The Coefficient of Variation (CV) is provided as an estimate of the precision of the data with respect to the mean for that location and maturity group. To provide some indication of yield stability, multiple-year means for yield and test weight are provided where trials have been conducted for more than one year with more than three entries per maturity group. Producers interested in comparing hybrids for consistency of yield in a specific area should consult these entries.

Variability of yields within hybrids was higher than desirable the 2017 season. Much of this variability can be associated with environmental conditions, particularly excessive moisture early and drought late-season. Plant populations were also lower and less uniform than usual, which may have contributed to the problem. Models with CV's above 20 or in the 20’s are not always reported, depending on location situations. However, when used it should be with the understanding that a higher than desirable degree of variability existed around sample means. Models with CV's greater than 25 have been included in this report.
