3 3 Introduction This report provides independent and unbiased information for the evaluation of commercial corn grain and silage hybrids available in Pennsylvania. The corn hybrid evaluation program provides farmers, seed corn companies, and university personnel with information on the relative performance of corn hybrids grown under Pennsylvania conditions. It should be used to supplement other sources of information, such as seed industry performance tests, other independent testing data, and on-farm performance records, when making hybrid selection decisions. This program encourages all seed companies in Pennsylvania to participate. Provided in Table 1 are the companies that participated in the 2016 commercial hybrid trials. Table 1.

4 4 GRAIN INFORMATION How to Use This Data The first factor to consider when using this report is hybrid maturity. In the table with each location listed, hybrids are listed alphabetically. Grain moisture is a good indicator of hybrid maturity. Hybrids with lower moisture are generally adapted to shorterseason environments. Identify hybrids in the list that you know are adapted to your area, and then evaluate new hybrids that have similar moisture contents. Selecting hybrids based on yield alone may result in a hybrid that is too late for your farm. Note that there is considerable range among maturity in hybrids entered in each zone. Once you have identified the appropriate hybrid maturity range, compare the yields of the hybrids that have been evaluated. Yield performance is variable across locations and best predicted by using data averaged over multiple locations, so the mean yield over all sites is the best guide to hybrid performance. Individual location hybrid means can help assess how consistent, or stable, the hybrid was across locations. For example, some hybrids may do well at high-yielding sites but may not do well at low-yielding sites. We do NOT recommend using data from a single site, even if it is close to your farm, to make hybrid selection choices. The hybrids listed in the combined table for each maturity zone are ranked in ascending order by yield with the highest-yielding hybrids at the top. Once you have identified some prospective hybrids, consider their standability from the lodged plants column. It also is important to check with a seed company representative about other characteristics of the hybrid that may be important for your operation. After you have gone through this process, you should be able to select hybrids that have above-average performance. This is an important part of profitable corn production since, as these reports demonstrate, there is a wide range in the performance of corn hybrids. Further, we recommend that you evaluate selected hybrids on your farm under your growing conditions and practices. This is the best way to make a final determination of the proper hybrids for your operation. Members of the county-based extension staff assisted in conducting these tests. Their efforts were essential to the successful completion of the trials and are greatly appreciated. Procedures Hybrids were planted in four-row plots equal to 1/250 of an acre. Planting was done with a vacuum precision planter at a seeding rate of of 34,000 plants per acre. Trials with corn following corn had granular insecticide placed in the row at planting. Planting dates ranged from April 25 to May 26 (Table 4). Entries were replicated four times at each location in a randomized complete block experimental design. Harvest began on October 12 and finished on November 10. Two center rows of each plot were harvested with a self-propelled combine equipped with electronic instrumentation for determining weight and moisture. Yields are reported as bushels per acre, while grain moisture and lodged plants are reported as percentages. Shelled grain yields were standardized at 15.5 percent grain moisture. Grain trial cooperator and location information is given in Table 4. Interpretation of Results The least significant difference (LSD) is a statistical tool used to determine if two average values are actually different. The difference between two hybrids must exceed the LSD value to be considered significantly different. For example, if LSD for yield = 8.1 Bu/A, and Hybrid X = 120 Bu/A, and Hybrid Y = 105 Bu/A, then = 15 Bu/A difference between the two hybrids. Since the difference between Hybrids X and Y (15 Bu/A) exceeded the LSD (8.1 Bu/A), Hybrid X was higher yielding due to hybrid superiority and not simply as a result of uncontrolled experimental errors. A coefficient of variation (CV) was also calculated. This is a relative value that measures the uncontrolled differences associated with that element of the test. For yield, a CV of 10 percent or less is usually good. Also included in this report is an economic value calculation column in the combined performance tables to assess the impact of drying costs on the potential economic returns from producing these hybrids. We assumed a grain price of $4.00 per bushel and a drying cost of $0.04 per bushel per point above 15 percent moisture. Actual grain drying and shrink charges vary considerably, but this provides some estimate of the potential economic returns from the hybrids when considering the impacts of grain moisture. Under some conditions (e.g., high-moisture corn), grain drying costs may not be important.

9 9 Zone 1 Grain Report Growing Conditions Zone 1 locations were planted May 12 and May 26. Growing conditions were variable within this zone. Rock Springs suffered the worst out of all locations from the drought. Other stresses were minimal. Bradford County looked good throughout the growing season. Two replications were dropped due to wet field conditions at harvest. Tioga and Indiana Counties were two of the better locations this year, having received more timely rainfalls. Disease, Insects, and Other Pests There was some ear mold development late in the season at Rock Springs. Other stresses were very minimal this year. Table 5.

11 11 Zone 2 Grain Report Growing Conditions Planting dates in this maturity zone ranged from May 11 to May 26. Only two replications were harvested at Bradford due to wet field conditions at harvest. This site looked good throughout the season with good weed control and optimum fertility. Two replications were dropped in Centre County for excessive field variability. This site suffered severely from the drought. Clinton was also negatively impacted by the drought. Indiana turned out to be one of the better plots this year with zero to minimal stresses and timely rainfall. Disease, Insects, and Other Pests As with Zone 1, there was some ear mold development late in the season in Centre and Clinton Counties. Table 7.

13 13 Zone 3 and Zone 4 Grain Report Growing Conditions Corn trials in these maturity zones ranged from April 25 to May 20. Hershey was one of the better fields this year. Although it did get dry, it did not seem to impact this field as much as others. Lehigh looked OK throughout the growing season, but it got very dry prior to and during ear development. Lycoming was by far the best looking field, having received adequate rainfall on very productive soils. Disease, Insects, and Other Pests At the Lycoming location, birds damaged the tops of the ears, leaving husks open to water. Ear molds developed late in the season and affected grain weight and quality. All other locations had no other stresses throughout the growing season. Table 9.

15 15 SILAGE INFORMATION Introduction This corn hybrid evaluation for silage production is a collaborative effort by Penn State and the Professional Dairy Managers of Pennsylvania (PDMP). The objective of the program is to evaluate corn hybrids in order to provide unbiased information to producers and the seed industry on yield performance and forage quality of corn hybrids for silage production in Pennsylvania. This report summarizes the 2016 results. The 2016 tests were conducted in the south-central, central, and northern tier regions of the state (Table 12). The 2016 short-season (Groups 0 and 1) northern tier tests were conducted at three locations: Jeff Morse (Morse Farms) in Bradford County, Gary Kline (Y Run Farm), also in Bradford County, and David Myers (David Myers Dairy) in Cambria County. A backup site was planted at the Penn State Agronomy Research Farm in Centre County. At these sites the very early maturity group consisted of 85- to 94-day hybrids and the early maturity group of 95- to 103-day hybrids. In this zone, the trial at the David Myers Farm was discarded due to bird and herbicide damage. The backup site planted at the Penn State Agronomy Research Farm was used. The 2016 South early mid-season (Group 2SC) south-central trials were conducted at two locations: Walt Moore (Walmoore Holsteins) in Chester County and Don Risser (Meadow Vista Dairy) in Lancaster County. The early maturity group consisted of 98- to 104-day hybrids and medium maturity of 105- to 110-day hybrids. In this zone, the trial at Walt Moore s was discarded due to severe deer damage. The backup site planted at the Landisville Research Station was used. The 2016 early mid-season (Group 2) central tests were conducted at three locations: Gordon England (Penn- England Farms) in Blair County, Phil Kulp (Kulp Family Dairy), also in Blair County, and Dan Ulmer (Guided Path Farm) in Centre County. The early maturity group consisted of 89- to 104-day hybrids and the medium maturity group of 105- to 111-day hybrids. In this zone, the trial at Kulp Family Dairy was discarded due to severe drought stress. Penn-England was also negatively impacted by the drought, but stress was fairly consistent throughout the field and data was used from this site. The backup site planted at the Penn State Agronomy Research Farm was used. The 2016 full-season (Groups 3 and 4) south-central tests were conducted at three locations: Don Risser (Meadow Vista Farm) in Lancaster County, Walt Moore (Walmoore Holsteins) in Chester County, and Dan Zug (Zugstead) in Juniata County. The medium maturity group consisted of 111- to 115-day hybrids and the late maturity group of 116- to 120-day hybrids. In this zone, the trial at Zugs was discarded due to cutworm damage. The backup site planted at the Landisville Research Station was used. The 2016 BMR tests were conducted at three locations: Don Risser (Meadow Vista Farm) in Lancaster County, Walt Moore (Walmoore Holsteins) in Chester County, and Dan Zug (Zugstead) in Juniata County. How to Use This Data These results can provide producers and the seed industry with performance data on commercial corn hybrids marketed for silage in the state. This data and individual location data are also available online in spreadsheet formats (extension.psu.edu/plants/ crops/grains/corn/hybrid-tests). Below are some suggested ideas to consider for evaluating hybrid performance information: 1. Concentrate mostly on the mean data from multiple locations. Hybrid performance varies from site to site, and the best predictor of future performance is the average performance over multiple locations. 2. Identify traits that are most important for your operation. Yield and some index of forage quality like milk per ton might be examples of traits that are important for your operation. Then look for hybrids that had above-average or top performance for both of those traits. 3. Compare hybrids that had a similar maturity or silage moisture at harvest within a test. Perhaps consider restricting your comparisons to the top or bottom half of a test. 4. Evaluate prospective hybrids with seed company representatives to make sure they have agronomic traits that are important for your conditions. 5. Consider evaluating new hybrids on a limited basis the first year. Develop a lineup of several hybrids that have similar nutritional characteristics to diversify your risks due to the effects of weather or disease on an individual hybrid performance. Procedures Hybrids were planted in four-row plots equal to 1/250 of an acre. Planting was done with a vacuum precision planter to obtain a final population of 34,000 plants per acre. Trials with corn following corn had granular insecticide placed in the row at planting. Planting dates ranged from May 9 to May 27 (Table 13). Each hybrid was replicated three times at each location. Prior to harvest, the dry matter concentration of several hybrids in each test was monitored and the harvests were targeted to achieve percent dry matter. All hybrids in each trial were harvested on the same day, beginning with the early hybrids at the Lancaster County site on August 29 and concluding in Centre County on September 21. Plots were harvested with a two-row research silage chopper at all locations. Two rows were harvested from each plot at a cutting height of approximately 12 inches. The forage was then weighed and thoroughly mixed. Samples were collected from the mixed chopped silage. Immediately after the plot was harvested, samples were stored in a portable freezer. Samples were then sent to the Cumberland Valley Analytical Services Laboratory in Hagerstown, Maryland, for analysis. The crude protein (CP), neutral detergent fiber (NDF), starch, lignin, 24-hour fiber digestibility (NDFD), and undf of each were analyzed. The BMR hybrids 24-hour NDFD were

16 16 analyzed using wet chemistry. These results were used to calculate the net energy for lactation (NEL). Milk yield per ton of dry matter was estimated from the forage analysis and yield using the Milk 2006 spreadsheet from the University of Wisconsin. New for 2016 Dairy nutritionists have developed a new test that may give an even better indication of the gut fill potential of hybrids. This is called the UNDF, or undigestible fraction of the NDF. For example, a hybrid with a UNDF of 30 percent means that after digestion of that sample for 24 hours, 30 percent of it would remain undigested. In this year s test, we are providing that analysis of hybrid to see what range there is, how variable it is, and how it is impacted by growing conditions. Interpretation of Results All data was analyzed using analysis of variance procedures, and least significant difference (LSD) values were calculated at the 0.10 level for each variable where the differences were statistically significant. When the difference between two hybrids exceeds the LSD (0.10) level, a 90 percent probability exists that it is not due to random variation. Small differences that are less than the LSD may be the result of random variation. A coefficient of variation (CV) was also calculated. This is a relative value that measures the uncontrolled differences associated with that element of the test. For yield, a CV of 10 percent or less is usually good. Production Conditions for 2016 Production conditions were challenging this year. The beginning of the season started cool and dry. Timely rainfalls occurred for most of May and in some areas into June, but for much of the state, rainfall was lacking for most of the growing season. Some of our locations received less than 8 inches of rainfall. A few locations had big, showy plants, but small ears. Other locations had stunted plants and small ears. The lack of rainfall had a negative impact on ear development. Yields for 2016 were below average.
