Goals / Objectives
To assess the agronomic performance of corn hybrids, the Ohio Corn Performance Test will provide unbiased information on corn hybrids that will increase grower profitability and minimize production risks.

Project Methods
The project will examine methods to detect superior corn performance and provide information on seed selection. Fertilizers, herbicides and insecticides will be applied that are proper for each geographic site and type of test conducted. Measurements will be taken on yield, plant and grain density, standability, ear and plant height, and silk date. Observations for diseases and insects will be made when such damage is sufficient to provide information. Laboratory analysis will be conducted on grain characteristics such as protein, oil and starch content. Standardized performance results will be made available in an annual public bulletin and world-wide web sites. Long-term results will be summarized to provide trends concerning yield and related agronomic traits. Other publications will report additional scientific findings.

Impacts
What was accomplished under these goals? In 2019, 163 corn hybrids representing 20 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for ten test sites statewide). Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments. Despite late planting dates and warmer and drier than normal conditions during grain fill, OCPT yields exceeded expectations. Averaged across hybrid entries in the early and full season tests, yields were 252 bu/A in the Southwestern/West Central/Central region, 234 bu/A in the Northwestern region, and 264 bu/A in the North Central/Northeastern region. Yields at individual test sites, averaged across hybrid entries in the early and full season tests, ranged from 215 bu/A at Hoytville to 282 bu/A at Hebron. Performance data for the Columbiana site in the North Central/Northeastern region is not presented due to excessive rainfall shortly after establishment and dry conditions during grain fill, which resulted in inconsistent yields. As of the publication date, Upper Sandusky in the Northwestern region was not harvested because of high grain moistures due to a late planting date. Results from Upper Sandusky will be available on-line after harvest.

Impacts
What was accomplished under these goals? In 2018, 192 corn hybrids representing 24 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for a total of ten test sites statewide). Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments. Growing conditions were very favorable for corn production across most of Ohio in 2018. Yields at OCPT test sites paralleled the record yields reported across the state this year. Averaged across hybrid entries in the early and full season tests, yields were 17.1 Mg/ha in the Southwestern/West Central/Central region, 14.9 Mg/ha in the Northwestern region, and 15.1 Mg/ha in the North Central/Northeastern region. Yields at individual test sites, averaged across hybrid entries in the early and full season tests, ranged from 12.7 Mg/ha at Beloit to 17.8 Mg/ha at Greenville. Performance data for Upper Sandusky in the NW region is not presented because excessive rainfall shortly after planting created variable field conditions that resulted in erratic stands, uneven growth and inconsistent yields.

Impacts
What was accomplished under these goals? In 2017, 205 corn hybrids representing 25 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for a total of ten test sites statewide). Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments. Despite excessive rainfall, which resulted in planting delays at several sites, as well as periods of dry weather during grainfill, OCPT corn yields generally exceeded those of recent years. Averaged across hybrid entries in the early and full season tests, yields were 16.8 Mg/ha in the Southwestern/West Central/Central region, 14.7 Mg/ha in the Northwestern region, and 14.6 Mg/ha in the North Central/Northeastern region. Yields at individual test sites, averaged across hybrid entries in the early and full season tests, ranged from 12.2 Mg/ha at Hoytville to 17.7 Mg/ha at Hebron. Lodging was largely absent across sites except at Van Wert and Upper Sandusky where some hybrids lodged as a result of heavy rains and strong winds in early November. Performance data for Washington Court House in the SW region and Bucyrus (Full Season) in the NE region are not presented due to variable field conditions that resulted in erratic stands, uneven growth and inconsistent yields.

What was accomplished under these goals? In 2016, 212 corn hybrids representing 26 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for a total of ten test sites statewide). Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments. Yields varied across the state depending on the timing and duration of drought conditions. Averaged across hybrid entries in the early and full season tests, yields were 15.1 Mg/ha in the Southwestern/West Central/Central region, 12.2 Mg/ha in the Northwestern region, and 12.4 Mg/ha in the North Central/Northeastern region. Yields at individual test sites, averaged across hybrid entries in the early and full season tests, ranged from 10.2 Mg/ha at Wooster to 16.1 Mg/ha at Hebron. The Wooster, Hoytville and Van Wert test sites were especially dry in June and July and averaged lower yields than other test locations. The full season tests averaged consistently higher yields than the early tests. Moldy grain was observed in some hybrids at Hebron and Beloit. Moderate to high levels of gray leaf spot were evident in a few hybrids at Bucyrus and Beloit. Lodging was largely absent across sites except at S. Charleston where some hybrids lodged as a result of heavy rains and strong winds in late August.

Impacts
What was accomplished under these goals? In 2015, 215 corn hybrids representing 27 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for a total of ten test sites statewide). Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments. The 2015 growing season in Ohio was characterized by record rainfall in June and July. Rainfall at Van Wert totaled 605 mm. However, total rainfall and distribution of rainfall differed considerably across test sites. Although soil conditions were excellent at planting for emergence, excessive rainfall and protracted periods of soil saturation at several sites resulted in highly variable corn growth and development that was associated with stunted plants and nitrogen deficiencies. Depending on the test site, excessive rainfall occurred in the early vegetative stages through the mid-late vegetative and tassel/silk vegetative stages. At several sites, including Beloit, Wooster and S. Charleston, August rainfall was below average. Temperatures were generally near normal to slightly above normal in May and below normal to near normal June through August. Warm dry conditions in September promoted crop maturation and dry down resulting in drier than normal grain moisture and higher test weights. Disease and insect pests were not a major factor at most test sites and stalk lodging was generally negligible. Symptoms of northern corn leaf blight and gray leaf spot were evident during grain fill and foliar fungicides were applied at the Hebron and Washington CH test sites. Dry conditions in August helped limit extensive disease development at other sites. Yields were mixed across the state. Averaged across hybrid entries in the early and full season tests, grain yields were 15.7 Mg/ha in the Southwestern/West Central/Central region, 11.7 Mg/ha in the North Central/Northeastern region, and 12.4 Mg/ha in the Northwestern region. Yields at individual test sites, averaged across hybrid entries in the early and full season tests, ranged from 9.3 Mg/ha at Beloit to 17.6 Mg/ha at Hebron. Performance data for Upper Sandusky in the Northwestern region and Greenville in the Southwestern/West Central/Central region are not presented because excessive rainfall shortly after planting combined with poor drainage resulted in highly uneven crop growth and inconsistent yields.

Impacts
What was accomplished under these goals? In 2014, 208 corn hybrids representing 28 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for a total of ten test sites statewide). Hybrid entries in the regional tests were planted in either an early or a full season maturity trial at each site. These test sites provided a range of growing conditions and production environments. Environmental conditions varied across Ohio during the 2014 growing season, especially with regard to the amount and distribution of precipitation. Excessive rainfall and saturated soil conditions in April and May delayed planting – most test sites were planted between May 20 and May 31. Nevertheless, yields at the late planted sites far exceeded expectations. Yields in the SW/WC/C region, averaged across hybrid entries and test sites, ranged from15.1 to15.4 Mg/ha, for the early and late matruity tests respectively; yields in thenNW region, averaged across hybrid entries and test sites, were12.6 Mg/ha for the early and late maturity tests respectively, and yields in the NE/NC region, averaged across hybrid entries and test sites, ranged from15.1 to15.4 Mg/ha for the early and late matruity tests, respectively. At the Hoytville test site in the NW region, stand reductions occurred due to crusted soils. Early season saturated soil conditions resulted in uneven crop development at the Upper Sandusky site in the NW region. Several sites experienced drier than average conditionsin July and August. However, major yield loss to water stress was limited by timely rains and below normal temperatures which limited stress. Performance data for Upper Sandusky in the NW region were not reported becausevaraible field drainage resulted in uneven crop growth and development. Late plantingandlate harvest dates due ot persistent rains generally resulted in high grain moistureand low test weightsat harvest.Despite favorable late season rainfall for disease development at several sites, stalk lodging was negligible – averaging no more than 5% at any location. Extensive foliar disease (primarily gray leaf spot and northern corn leaf blight) was evident late in the season at several locations but impact on crop performance appeared limited.

Impacts
What was accomplished under these goals? In 2013, 240 corn hybrids representing 28 companies and 33 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for a total of ten test sites statewide). Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments. Record high yields were achieved at most test locations due to ample and timely rainfall and moderate temperatures which created near stress-free growing conditions for most of the growing season. Averaged across hybrid entries in the early and full season tests, grain yields in the Southwest and West Central region and the North Central and Northeast region were 239 bu/A, whereas yields in the Northwest region were 248 bu/A. At the Hebron and Upper Sandusky test sites in the SW/WC/C and NW regions, respectively, there were several hybrids with average yields of 300 bu/A or greater. Performance data for South Charleston in the SW/SC region and Bucyrus in the NC/NE region are not presented. At these sites, excessive rainfall (S. Charleston) and wind damage (Bucyrus) created variable field conditions resulting in inconsistent yields.

OUTPUTS: In 2012, 236 corn hybrids representing 30 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for a total of ten test sites statewide). Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments. Although record high temperatures and dry conditions were widespread across Ohio during the 2012 growing season, most OCPT sites received timely rains that blunted the impact of these stress conditions. At most OCPT sites, drier and much warmer than normal conditions persisted from the early vegetative stages through early to mid grain fill. All test sites except Wooster, experienced one or more days with temperatures of 37.8 degrees C or more during the late vegetative stages, the pollination period and/or the early grain fill stages from late June to mid July. Greenville and Van Wert experienced a total of five days with temperatures (and four consecutive days) of 37.8 degrees C or more. Greater than normal rainfall and cooler than normal temperatures in September slowed kernel maturation and delayed drydown and harvest. At most test sites, the impact of high temperatures in July on crop performance was limited because it either preceded pollination or timely rainfall and adequate soil moisture reduced adverse effects. Yields were highest at S. Charleston and Washington CH (averaging 14.6 and 14.5 Mg/ha, respectively) and lowest at Beloit and Greenville (averaging and 9.3 and 9.7 Mg/ha, respectively). Several locations, including S. Charleston, Upper Sandusky and Van Wert, experienced green snap injury and widespread root lodging due to strong winds from June 30 to July 1. There was considerable variability among hybrids for root lodging and green snap. Much of the root lodged corn recovered and showed little evidence of injury at harvest. However, green snap injury generally broke stalks off near or at the base of the plant. Averaged across the early and full season maturity tests, % green snap for hybrids evaluated at S. Charleston, Upper Sandusky and Van Wert averaged (range indicated in parentheses) 6% (0-44%), 3% (0-35%), and 1% (0-21%), respectively. Below average temperatures and persistent rains in September and October delayed crop maturation and resulted in higher than normal grain moisture at harvest at several locations. Despite the water stress present at most sites, stalk lodging was negligible - averaging no more than 7% at any location. Extensive foliar disease (northern corn leaf blight and gray leaf spot) was evident late in the season at some locations but impact on crop performance appeared to be limited.Over 36,000 copies of the Ohio Corn Performance Test report were distributed.

TARGET AUDIENCES: corn growers, agricultural extension educators, seed company/agribusiness personnel PROJECT MODIFICATIONS: Not relevant to this project.

Impacts
The results of the performance tests are used by many Ohio corn growers to select superior corn hybrids. The results were published in November and growers used the report immediately to choose hybrids for planting in the spring of 2013. The results allow growers to identify hybrids with above average yields and good stalk quality and dry down characteristics. As a result of this test, thousands of Ohio corn growers make better informed decisions on which hybrid to plant on their farms. The difference in yield between the highest and lowest yielding hybrids in each test, averaged across the ten test sites in 2012, was 63 bu/A and 58 bu/A, respectively, for the early and late maturing hybrid trials. These yield differences translate into $431/A and $438/A based on corn price of $7.00/bu and a drying charge of $0.03 for each percentage point above a 15.5% moisture content. A one bushel increase in yield at current prices across Ohio's 3.65 million harvested corn acres in 2012 represents a gain of more than $25,000,000.

OUTPUTS: In 2011, 251 corn hybrids representing 32 commercial brands were evaluated in the Ohio Corn Performance Test. Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions for a total of ten test sites statewide. Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments. Environmental conditions varied considerably across Ohio during the 2011 growing season, especially with regard to the amount and distribution of precipitation. Excessive rainfall in April and May delayed planting - four test sites were planted in mid-May; four in late May, and two in early June. Nevertheless, yields at the late planted sites far exceeded expectations. Yields at test sites planted May 31 to June 3, averaged across hybrid entries, ranged from 13.2 to 15.8 Mg/ha, whereas yields at test sites planted May 10 to 13 ranged from 9.2 to 15.3 Mg/ha. At some of the test sites planted in May (Van Wert and Washington CH), stand reductions occurred due to excessive soil moisture. Saturated soil conditions resulted in seedling blights and limited early season root development resulting in shallow root systems. Several sites (Van Wert, Greenville, and Upper Sandusky) experienced warmer and drier than average conditions from June through July. However, major yield loss to water stress was usually limited by timely rains and adequate soil moisture. Other test sites received adequate rainfall that was well distributed throughout the growing season. Rainfall was above normal at all test sites in September during late grain fill and maturation. Performance data for Van Wert in the NW region and for the early maturity trial at Washington CH in the SW/WC/C region were not reported because heavy rains shortly after planting resulted in excessive soil moisture that that led to major stand reduction. A period of high temperatures in July had little effect on crop performance because it either preceded pollination or timely rainfall and adequate soil moisture limited adverse effects. Yields were highest at Hebron in the Central region and Upper Sandusky in the NW region (averaging nearly 15.7 Mg/ha) and lowest at Greenville in the WC region (averaging slightly less than 11.3 Mg/ha). In contrast to 2010, below average temperatures and persistent rains during late grain fill in September delayed crop maturation and resulted in much higher than normal grain moisture at harvest. Despite varying degrees of stress present at several sites, stalk lodging was negligible - averaging no more than 5% at any location. Extensive foliar disease (primarily northern corn leaf blight) was evident late in the season at several locations but impact on crop performance appeared to be limited.

The results of the performance tests are used by many Ohio corn growers to select superior corn hybrids. The results were published in November and growers evaluated the findings immediately in determining hybrids to plant in the spring of 2012. The results allow growers to identify hybrids with above average yields and improved stalk quality and dry down characteristics. As a result of this test, thousands of Ohio corn growers make better informed decisions on which hybrid to plant on their farms. The difference in yield between the highest and lowest yielding hybrids, averaged across the nine test sites in 2011, was 52 bu/A and 63 bu/A, respectively for the early and late maturing hybrid trials. These yield differences translate into $309/A and $364/A based on a current corn price of $6.00/bu and a drying charge of $0.03 for each percentage point above a 15.5% moisture content. A one bushel increase in yield at current prices across Ohio's 3.22 million corn acres represents a gain of more than $19,000,000.

OUTPUTS: In 2010, 299 corn hybrids representing 35 commercial brands were evaluated in the Ohio Corn Performance Test. Testing was conducted in three regions of Ohio - Southwestern/West Central (SW/WC); Northwestern (NW); and North Central/Northeastern (NC/NE), with three test sites established within each region. Testing was also conducted at Coshocton, an area with high gray leaf spot incidence. Entries in the regional tests were planted in either an early or full season maturity trial. These test sites provided a range of growing conditions and production environments. Environmental conditions varied greatly across Ohio during the 2010 growing season, especially with regard to the amount and distribution of precipitation. Yields were highest at the S. Charleston and Washington CH test sites in the SW region (averaging above 15.2 Mg/ha) and lowest at Hoytville in NW Ohio and Beloit in NE Ohio (averaging less than 9.3 Mg/ha). At most test sites, rainfall from planting through the mid to late vegetative stages of corn development was above normal. Excessively wet soils in May and June limited early season root development and resulted in shallow root systems. Saturated soil conditions contributed to reduced emergence of some hybrids. Dry weather conditions combined with above average temperatures persisted from the late vegetative stages through maturity at most sites. Water deficits were especially severe at the Hoytville test site. Test results from Greenville in the SC/WC region and Wooster in the NC/NE region test locations are not reported because of weather related damage. At Greenville, heavy rains shortly after planting, in combination with late season water stress, resulted in erratic stands that led to highly variable yields. At Wooster, strong winds associated with a tornado on Sept. 16, destroyed and flattened much of the corn test. At other test sites, water stress was limited by timely rains and adequate soil moisture. In contrast to 2009, high temperatures during grain fill accelerated crop maturation and resulted in much lower than normal grain moisture at harvest. Despite the varying degrees of stress present at most sites, stalk lodging was negligible - averaging no more than 5% at any location. Extensive foliar disease (primarily gray leaf spot and northern corn leaf blight) was evident late in the season at several locations but impact on crop performance appeared to be limited. Grain yields in the Southwest and West Central region (the S. Charleston and Washington C.H. locations), averaged across hybrid entries in the early and late trials, were 15.5 Mg/ha. Yields in the Northwest region (Van Wert, Hoytville, and Upper Sandusky locations) averaged across hybrid entries in the early and late trials, were nearly 11.6 Mg/ha. Yields in the North Central and Northeast region (the Bucyrus and Beloit locations) averaged across hybrid entries in the early and late trials, were 11.3 Mg/ha. In addition hybrid yields at Coshocton averaged 13.3 Mg/ha. PARTICIPANTS: P.Thomison, R.Minyo, A. Geyer, Horticulture and Crop Science D. Lohnes, and B.

OUTPUTS: In 2009, 267 corn hybrids representing 37 commercial brands were evaluated in the Ohio Corn Performance Test. Testing was conducted in three regions of Ohio - Southwestern/West Central; Northwestern; and North Central/Northeastern, with three test sites established within each region. Testing was also conducted at Coshocton, an area with high gray leaf spot incidence. Entries in the regional tests were planted in either an early or full season maturity trial. These test sites provided a range of growing conditions and production environments. Growing conditions were highly favorable for corn at most test locations. The 2009 growing season was generally characterized by lower than normal temperatures, especially during flowering and early-mid grain fill. Rainfall during the critical pollination and early grain fill periods was generally above normal or near normal except at Hoytville, which experienced dry weather from the late vegetative stages through maturity. Because of cooler temperatures, crop development was slower than normal at most test sites which delayed harvest and contributed to higher than normal harvest grain moisture and lower test weights. Stalk lodging was negligible - averaging no more than 5% at any location. Diseases and insect pests were generally not a significant factor at test sites. Extensive foliar disease (primarily gray leaf spot) was evident late in the season at Washington CH and S. Charleston but impact on crop performance appeared to be limited. Record high yields were achieved at most test locations due to ample and timely rainfall and moderate temperatures which created near stress-free growing conditions for most of the growing season. Grain yields in the Southwest and West Central region (the S. Charleston, Washington C.H., and Greenville locations), averaged across hybrid entries in the early and late trials, were nearly 15 Mg per ha. Yields in the Northwest region (Van Wert, Hoytville, and Upper Sandusky locations) averaged across hybrid entries in the early and late trials, exceeded 13.8 ha per ha. Yields in the North Central and Northeast region (the Bucyrus, Wooster, and Beloit locations) averaged across hybrid entries in the early and late trials, exceeded 14.4 Mg per ha. In addition hybrid yields at Coshocton averaged 14.9 ha per ha. Over 36,000 copies of the Ohio Corn Performance Test report were distributed.

In 2006, 225 corn hybrids representing 38 commercial brands were evaluated at 10 sites across a range of Ohio corn growing environments. Entries were evaluated in either an early or full season maturity trial. One test was conducted in an area known to contain a high incidence of gray leaf spot. Data were obtained on relative hybrid performance including yield, stand, lodging, grain moisture content, emergence, days to mid-silk, test weight, protein, oil and starch. Although growing conditions were generally warmer and drier than normal during the grain fill period (approx. mid July through late August), excellent yields were recorded at several test sites. The month of October was the second wettest in 124 years and 2006 was one of the latest, coldest, and wettest harvest seasons of the last 40 years. Stalk lodging was generally negligible except for the Wooster site. At Wooster, lodging ranged from 0 to 46% for hybrids in the early maturity test and 0 to 63% for hybrids in the full season trial. Average test site values for grain yield ranged from 10.3 Mg/ha to 13.5 Mg/ha. Grain moisture content at harvest ranged from 14.6% to 31.8%. Grain oil content ranged from 3.7% to 3.9% while protein ranged from 7.8% to 8.8%.

In 2005, 207 corn hybrids representing 37 commercial brands were evaluated at 11 sites across a range of Ohio corn growing environments. Entries were evaluated in either an early or full season maturity trial. Data were obtained on relative hybrid performance including yield, stand, lodging, grain moisture content, emergence, days to mid-silk, test weight, protein, oil and starch. Environmental conditions varied greatly across Ohio during the 2005 growing season, especially with regard to the amount and distribution of precipitation. Cool, wet soil conditions during emergence and early vegetative growth were followed by warm, dry conditions that began as early as mid June at some locations. Temperatures during grain fill were generally warmer than normal. Rainfall was near normal to below normal. Rainfall deficits were most pronounced at test sites in the Southwestern and West Central region. Despite periods of hot, dry weather, excellent grain yields were recorded at several test sites in northern Ohio. Stalk lodging was severe at the three test sites in southwestern and west central Ohio, which was the region most affected by drought conditions. However, stalk lodging was negligible at other test sites. Average test site values for grain yield ranged from 10.4 Mg/ha to 12.8 Mg/ha. Grain moisture content at harvest ranged from 17.2% to 23.2%. Grain oil content ranged from 3.8% to 4.0% while protein ranged from 8.4% to 8.8%. Over 30,000 copies of the Ohio Corn Performance Test report were distributed.

In 2004, 200 corn hybrids representing 34 commercial brands were evaluated at 11 sites across a range of Ohio corn growing environments. Entries were evaluated in either an early or full season maturity trial. Two tests were conducted in areas known to contain a high incidence of corn virus and gray leaf spot. Data were obtained on relative hybrid performance including yield, stand, lodging, grain moisture content, emergence, days to mid-silk, test weight, protein, oil and starch. Above average rainfall and moderated temperatures contributed to excellent yields at most locations. Foliar diseases and ear rots, especially northern corn leaf blight and diplodia ear rot were present at several sites. Significant disease injury was limited to particularly susceptible hybrids. Stalk lodging was generally negligible except for the Wooster site. At Wooster, lodging ranged from 0 to 46% for hybrids in the early maturity test and 0 to 63% for hybrids in the full season trial. Persistent rains from early May through mid June prevented timely planting of the Bucyrus and Beloit test sites in North Central/Northeast Ohio. Average test site values for grain yield ranged from 10.3 Mg/ha to 13.5 Mg/ha. Grain moisture content at harvest ranged from 14.6% to 31.8%.

Outputs
In 2003, 239 corn hybrids representing 37 commercial brands were evaluated at 9 sites across a range of Ohio corn growing environments. Entries were evaluated in either an early or full season maturity trial. Two tests were conducted in areas known to contain a high incidence of corn virus and gray leaf spot. Data were obtained on relative hybrid performance including yield, stand, lodging, grain moisture content, emergence, days to mid-silk, test weight, protein, oil and starch. Above average rainfall and moderated temperatures contributed to excellent yields at most locations. However persistent rains from early may through mid June prevented timely plantings of two sites in NE Ohio. Results from these sites were not reported because killing frosts occurred before matured and resulted in major yield reductions. Average test site values for grain yield ranged from 9.5 Mg/ha to 12.8 Mg/ha. Grain moisture content at harvest ranged from 17.5% to 23.4%. Grain oil content ranged from 3.6% to 3.8% while protein ranged from 7.9% to 8.5%. Stalk lodging was negligible. Over 36,000 copies of the Ohio Corn Performance Test report were distributed. The results were also disseminated via the web http://www.oardc.ohio-state.edu/corn2003/

Impacts
Over 36,000 copies of the performance trial report were distributed. To expedite delivery of results to corn growers and seed companies, results are also made available prior to hard copy publication on the web (http://www.oardc.ohio-state.edu/corn2003/

Outputs
In 2002, 236 corn hybrids representing 38 commercial brands were evaluated at 11 sites across a range of Ohio corn growing environments. Entries were evaluated in either an early or full season maturity trial. Two tests were conducted in areas known to contain a high incidence of corn virus and gray leaf spot. Data were obtained on relative hybrid performance including yield, stand, lodging, grain moisture content, emergence, days to mid-silk, test weight, protein, oil and starch. Severe drought reduced yields sharply at test sites in Northwest and Northeast Ohio. Averaged across location and hybrid, grain yields ranged from 4.5 Mg ha-1 to 9.7 Mg ha-1. Grain moisture content at harvest ranged from 17.4% to 23.3%. Grain oil content ranged from 3.3% to 5.0% while protein ranged from 7.2% to 11.2%.
