1 PR Kentucky Small Grain VARIETY Performance Test B. Bruening, C. Tutt, S. Swanson, J. Connelley, G. Olson, N. Mundell, A. Clark, and D. Van Sanford The 2007 soft red winter wheat growing season ended with Kentucky farmers harvesting 240,000 acres of the 440,000 acres planted for a total production of 12.2 million bushels of grain. An average yield of 51 bushels per acre was recorded. State yields were compromised by freeze damage and were lower than in the previous two record years (Table 1). Small grain performance tests were conducted in six of the seven agroclimatic regions of Kentucky (Table 2). Agricultural areas within each region are considered to have similar soil types and climatic conditions. Each region having a substantial acreage of a small grain commodity had at least one trial conducted in that region for that commodity. The objective of the Kentucky small grain variety performance test is to evaluate varieties of wheat and barley that are or may soon be commercially available to Kentucky farmers. New varieties are continually being developed by agricultural experiment stations and commercial firms. Annual evaluation of small grain varieties and selections provides farmers, seed producers, and other agricultural workers with current information to help them select the varieties best adapted to their locality and individual requirements. Because weather, soil, and other environmental factors may alter varietal performance from one location to another, seven grain production tests were conducted at seven locations throughout the state (Table 2). Additionally, tests for varietal differences in forage potential and straw yields were conducted at one location. The Southern Tier No-Till test in Todd County was dropped due to severe freeze damage (similar to the Purchase Region test). Experimental Methods Seventy-two entries were evaluated under either conventional or no-till cultural practices. No-till tests were conducted at four locations, and conventional tillage tests were conducted at three locations. The experimental design was a randomized complete block. The tests had four replications per entry, and the data presented are the average response from the four replications. The plots were planted with specially built multi-row conventional and no-till cone seeders. Conventional test plots consisted of six rows to form a plot 4 feet wide and 15 feet long, which was later trimmed to 10 feet in length. No-till plots consisted of seven rows to form a plot 4.5 feet wide and 25 feet long, which was later trimmed to 20 feet in length. Plots were harvested with a small plot combine. Table 1. Wheat harvested (1,000 acres) and yields (bu/acre) in Kentucky, * Harvested Yield Harvested Yield Harvested Yield *July 1, 2007, National Agricultural Statistics Service Tests were conducted using intensive management practices. Typical herbicide applications included a spring application for broadleaf control and a fall preplanting burn-down (no-till tests only) application. Fungicides were applied in the spring on all but two (disease rating) tests. An insecticide for aphid control was typically applied in the fall and spring. Nitrogen was applied in a February/March split application at a rate of approximately 30/60 lbs/a (conventional tests) or 35/70 lbs/a (no-till). Table 2.

2 The forage test was planted using conventional tillage and was harvested using a small plot forage combine at the beginning of the heading stage. Dry matter forage yield and winter grazing potential were determined. Straw yield was recorded using a small plot forage combine following grain harvest at the Bluegrass Region test. Characteristics Evaluated Grain yields were calculated from the weight of grain from each plot and reported in bushels per acre (Bu/A) based on a 60-lb standard bushel weight at 13.5% moisture content. Test weights (pounds per bushel) were determined using a GAC 2100b. Lodging was reported as the percentage of plant lodging at maturity. Plant height was measured in inches from the soil surface to the top of the grain head. Heading dates were reported as the day that an estimated 50% of the heads had extended above the flag leaf collar. Disease ratings were not recorded in 2007 due to low disease pressure; 2006 disease rating data are presented. Head scab ratings were recorded at the Fayette county Fusarium head blight nursery. Forage and straw yields are expressed as dry matter in tons per acre. Freeze damage ratings were recorded at the Caldwell and Fulton county tests where severe freeze damage occurred. Stem and canopy damage was recorded, averaged, and reported as freeze injury (scale 1-8). Kernel weight (1000) was determined using cleaned, unscreened seed from the Bluegrass Region test. Results and Interpretation Since genetic expression of a variety is greatly influenced by environmental conditions, it is best to have several years data at multiple locations from which to draw conclusions. Performance of a variety tested for only one year should not be compared with a three-year average of another variety. It is possible that results in one of the other years were extremely good or poor and, thus, not comparable. Because the 2007 tests were compromised by freeze damage, 2006 yield data are presented for each test. The 2006 overall statewide summary (Table 3) has been republished and is the recommended table for variety selection. The yield of a variety is relative and should be compared with the yields of the other varieties in the same experiment and at the same location or within the same analysis across locations. Small differences in yield only a few bushels per acre between two varieties from an individual test should not be interpreted to indicate the superiority of one variety over another. However, if one variety consistently out yields another over a period of several years, the chances are that the differences are real. LSD (least significant difference) values are listed at the bottom of table columns to indicate whether differences are statistically significant. Lodging data are very difficult to interpret. A high-yielding variety should not necessarily be downgraded because of a high percentage of lodging for a given year at a given location. Local weather conditions, such as wind and rain, may cause a variety to lodge much more than it does normally. Variety trials normally have a greater degree of lodging than do farmer fields. It should also be emphasized that a variety reported to be 50% lodged does not imply that only 50% of the grain could be harvested. With good equipment, almost all of the grain can often be saved. Kentucky s climate and soils are well suited for the production of high-quality soft red winter wheat. No single variety has all the desirable characteristics, but each has certain advantages. Grain yield potential and test weight, straw strength and yield, height, heading date, disease resistance, and forage production potential are all important in choosing a variety. Winter barleys are less winter-hardy than winter wheat but more hardy than winter oats. The degree of winter-hardiness, straw strength, and maturity are important characteristics when choosing a variety. Barley (commercial varieties and experimental hulless lines) performance data are presented in Tables 13 and 14. Test Conditions Dry, warm weather during early October facilitated partial early planting of Kentucky s 2007 wheat crop. Wet weather in mid- October delayed some planting until late October/early November. Cool temperatures in November slowed plant development, but growth accelerated with warm December temperatures. The 2007 small grain variety tests were planted between the 10th and 30th of October. Record warm temperatures in March stimulated vigorous growth and development. Severe freeze damage occurred April 6-9, with highs in the upper 20 s and lows in the mid-teens. The majority of the state s wheat crop was at Feekes The level of damage was related to stage of development and the susceptibility of varieties to cold stress. Certain varieties were less susceptible to freeze damage independent of growth stage. Insect and disease pressure were low. Although harvest date was expected to be delayed due to re-growth associated with freeze damage, a warm, dry May accelerated maturity. Dry conditions during early June favored timely harvest and decent grain quality.

Disease Ratings...17 IMPORTANT NOTE: Much of Kentucky s 2007 wheat crop sustained freeze damage during April 6-9 th (daily temperatures ranged from mid-teens to upper 20 s). This freeze was preceded by three weeks of abnormally high temperatures which accelerated wheat growth and development and increased the susceptibility to freeze damage. The 2007 variety tests were affected as well. With the exception of the Bluegrass region tests, all other tests sustained moderate to severe freeze damage. Because the 2007 data was compromised by freeze damage, the 2006 state summary of all tests (*Table 3) has been republished and is the recommended data set for variety selection decisions. The 2007 data is interesting, but may or may not represent varietal performance in a typical year. There were indicators that yield performance was related to the stage of development (at freeze), but other factors were also involved. Deciphering why some varieties appeared to be more/less susceptible to the freeze will require the analysis of these and other data collected from the tests. The analysis and interpretation of this topic, is beyond the scope of this bulletin and will be summarized later. The 2007 data for individual tests is presented along with 2006 yield data for performance comparison in an ideal (record year) environment. Planting date and approximate stage of development at time of freeze are noted for each test. Height and heading date data were affected by freeze and the best estimate of these 2007 characteristics is from the Bluegrass regional test. 4
