1 AGRICULTURAL EXPERIMENT STATION UNIVERSITY OF KENTUCKY COLLEGE OF AGRICULTURE, FOOD AND ENVIRONMENT, LEXINGTON, KY, PR Kentucky Small Grain PERFORMANCE TEST B. Bruening, R. Curd, S. Swanson, J. Connelley, G. Olson, A. Clark, and D. Van Sanford The 2013 soft red winter wheat growing season ended with Kentucky farmers harvesting 580,000 acres of the 680,000 acres planted, for a total production of 42.3 million bushels of grain. A record average yield of 73 bushels per acre is expected (Table 1). The acreage not harvested for grain was primarily used for forage production. 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, oat, and barley that are commercially available or may soon be 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 tests were conducted at seven locations throughout the state (Table 2). In addition, wheat and oat tests for varietal differences in forage potential and straw yields were conducted at one location. trimmed to 20 feet in length. Plots were harvested with a small plot combine. The preceding crop for all tests was corn. 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 pounds per acre (conventional tests) or 40/70 pounds per acre (no-till). Table 1.

No-till tests were grown at three locations, and conventional tests were grown at four 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 12 feet in length. No-till plots consisted of seven rows to form a plot 5 feet wide and 25 feet long, which was later Table 2. Agroclimatic regions of Kentucky small grain variety tests.

2 The forage test was planted using conventional tillage and was harvested using a small plot forage combine at the milk stage. Straw yield was measured using a small plot forage combine following grain harvest in the Bluegrass Region test. Characteristics Evaluated Grain yields were calculated from the weight of grain from each plot and reported in bushels per acre based on 60-pound, 48-pound, and 32-pound standard bushel weights for wheat, barley and oats, respectively at 13.5 percent moisture content. Test weights were determined using a Harvest- Master Classic GrainGage and adjusted to 13.5 percent moisture. was reported as the percentage of plant lodging at maturity; winter survival was reported as the percentage of survival after spring green-up. Winter survival was 100 percent for all locations. Plant height was measured in inches from the soil surface to the top of the grain head. Heading dates were reported as the day an estimated 50 percent of the heads had extended above the flag leaf collar. Disease ratings (leaf blotch complex and fusarium head scab ratings) were recorded at the Logan County (non-fungicide) test. Fusarium head scab was also rated with powdery mildew at Lexington, Ky. Forage and straw yields are expressed as dry matter in tons per acre. 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 multi-year average of another variety because it is possible that results in one of the other years were extremely good or poor and thus not comparable. 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 of 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 outyields 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. 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 normally does. 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 percent lodged does not imply that only 50 percent of the grain could be harvested. With good equipment, most of the grain can often be saved. Substantial lodging was recorded across the test locations in 2013 and may have been the result of excess carry-over nitrogen in the soil from the previous drought affected corn crop. 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. potential, straw strength and yield, height, heading date, grain quality, disease resistance, and forage potential are important in choosing a variety. Winter barley is 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 (hulled and hull-less) variety performance data are presented in Tables 13 and 14. Oat forage, grain, and straw yield data are presented in Table 15. Test Conditions Cool temperatures and slightly less precipitation during October facilitated timely planting throughout much of the state. The 2013 Kentucky small-grain variety tests were planted between October 11 and October 25. Cool temperatures from November through February limited growth of later planted wheat. Early planted wheat had substantial growth and development and may have been stimulated by excess carry-over soil Nitrogen unused by the previous drought affected corn crop. Warmer temperatures in March stimulated plant growth. Frequent rainfall in April and May favored leaf blotch disease pressure throughout the state. Head scab developed later in Central Kentucky. Mild, wet conditions in May and June delayed maturity and dry-down. In some areas, harvest was delayed due to frequent rainfall in mid- to late June.
