2001 Corn Performance Tests (RR 675)

Anton E. Coy, J. LaDon Day and Paul A. Rose, Editors

Preface

In this research report, the results of the 2001 corn performance trials are presented. Corn performance trials were conducted at six locations throughout Georgia (see map below) and two locations in Florida in 2001. Short-season, mid-season and full-season hybrids were planted at Tifton, Plains and Midville in the coastal plain region, at Griffin in the Piedmont region, at Calhoun in the limestone valley region, at Blairsville in the mountain region and at Quincy and Jay in the panhandle region of Florida. Hybrids used for silage were evaluated at Tifton, Griffin, Calhoun and Blairsville, Georgia, and at Quincy and Ona, Florida. Preliminary experimental hybrids were tested at Tifton only.

At each site, all plots within a maturity group were seeded at the rates specified and not thinned, and the populations at harvest are included in the tables. Information concerning fertilization and cultural practices used in each trial is included with the tables. Grain harvesting was done with a small plot combine, and yields were adjusted to 15.5 percent moisture. Since data averaged over several years indicate a hybrid's yield potential better than data from only a single year, average yields over several years are included in this report.

The least significant difference (L.S.D.) at the 10 percent level has been included in the tables to aid in comparing hybrids. If the yields of any two hybrids differ by the L.S.D. value or more, they can be considered different in yield ability. Bolding is used in the performance tables to indicate hybrids with yields statistically equal to the highest yielding entry in the test. The standard error (Std. Err.) of an entry mean is included at the bottom of each table to provide a general indicator of the level of precision of each experiment. The lower the value of the standard error of the entry mean, the more precise the experiment.

Producers of hybrid seed corn are invited to enter their hybrids in the Georgia performance trials. Most hybrids entered are commercially available in Georgia, but a few experimental hybrids are also entered. Entry of a hybrid in these trials does not imply endorsement or recommendation by the University of Georgia College of Agricultural and Environmental Sciences.

This report is one of five publications presenting the 2000-2001 performance of agronomic crops in Georgia. For information concerning the performance of other crops, refer to one of the following research reports: 2000-2001 Small Grains Performance Tests, Experiment Station Research Report #673; 2000-2001 Canola Performance Tests, Experiment Station Research Report #674; 2000 Soybean, Sorghum Grain and Silage, Grain Millet, Sunflower and Summer Annual Forages Performance Tests, Experiment Station Research Report #670; and 2000 Peanut, Corn and Tobacco Performance Tests, Experiment Station Research Report #671.

The Season

The 2001 corn season was generally favorable for grain production. Wet soils in late March delayed planting in south Georgia. By mid-April, adequate moisture and above normal temperatures allowed emergence to be ahead of average. In May, normal daytime and below normal night-time temperatures favored corn growth except for above normal temperatures during the last week. Near normal temperatures and generally adequate moisture conditions allowed the crop to progress at a near average pace through June. Some areas continued to receive good rainfall during July while others began to stress. Favorable conditions allowed maturity to progress at an average pace. Some areas in southwestern Georgia were affected by leaf diseases but, in general, plant health was good. Harvest and storage insect numbers were above average in some areas.

Soil moisture conditions during the season were more nearly normal than any year since 1997. Rainfall at the six Georgia and at the Quincy, Florida, corn variety test sites is listed below.

Harvest proceeded a week behind average with generally good field conditions. Of the 280,000 planted acres, some 220,000 were harvested for a record estimated average yield of 126 bushels per acre. Total grain production for 2001 was 27.7 million bushels, an 18-percent decrease from 2000.

1 Quality factors taken from the replicated silage trial at Tifton.
2 This variable is calculated to reflect the relative contribution of each component using the following formula:
whole plant IVDMD = fodder IVDMD X percent fodder + grain IVDMD X percent grain.
3 The F-test indicated no statistical differences at the alpha = .10 probability level; therefore an LSD value was not calculated.

Bolding indicates entries performing equally to highest performing entry within a column based on Fisher's protected LSD (P = 0.10).

INSECT SCREENING RESULTS

Evaluation of Corn Hybrids for Resistance to Insects

N. W. Widstrom and B.G. Rector

Environmental conditions in Georgia during the 2001 growing season were favorable for buildup of insect populations large enough to cause damage to corn. Generally, this damage is greatest in late-planted corn left in the field for an extended period past maturity.

It is recommended that hybrids resistant to insects be planted. These hybrids are presently the only economical means, in late plantings, for the reduction of damage by corn earworm, fall armyworm, maize weevil, and pink scavenger caterpillar. Consult your local county agent and/or extension entomologist for additional control recommendations for other insects.

Percent yield losses attributable to all insects for individual hybrids varied from 0.7% to 6.0% and are reflected by VG, G, F, P, and VP ratings in the tables. Hybrids in the tests sustained average yield losses of 2.1% and 3.1% in the full and mid-season, and short-season hybrid tests, respectively. The mean level of overall yield loss for all tests was 2.7%. Of the total loss, about 37% was attributable to ear injury by the corn earworm, 53% to the pink scavenger caterpillar, and 10% to the maize weevil. Losses to the pink scavenger caterpillar and maize weevil are based on damage by multiple generations of these insects as the corn dries in the field. Timely harvest will substantially reduce losses to these two insects.

Evaluations for resistance to corn earworm and fall armyworm, maize weevil, and pink scavenger caterpillar are given for hybrids in the tables following. Lettered ratings refer only to relative resistance to insects and are not indicative of yield. Thus, a hybrid rated poor for resistance to insects might possibly be among the highest yielders and vice-versa. See the yield data in other tables for this information.

Husk tightness ratings were assigned using a scale of 1 to 5, in which 1 = very loose and 5 = very tight. No average rating was less than 2.0 or greater than 4.0; therefore, only loose, medium, and tight ratings are given in the tables.

Both the hybrid tests (full and mid-season, and short-season) were planted April 26, 2001. Plantings were delayed in 2001 due to dry field conditions during March and April. Plots were thinned to 20,000 plants per acre. Ratings for overall insect damage were completed during September.

Data for this section were compiled by J. M. Cook, J. C. Mullis, C. A. Pearl, Brad Arrington, and Heather Roberts of the United States Department of Agriculture, Crop Genetics and Breeding Research Unit, and Georgia Coastal Plain Experiment Station, Tifton, Georgia.
