6000 1999 Corn Performance Tests | UGA Cooperative Extension
Research Report 661

Preface

In this research report, the results of the 1999 corn performance trials are presented. Corn performance trials were conducted at six locations throughout Georgia in 1999 (see map below). 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, and at Blairsville in the mountain region. High oil corn hybrids were tested at Tifton and Plains. Hybrids used for silage were evaluated at Tifton, Griffin, Calhoun, and Blairsville, Georgia, and at Quincy, 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% 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% 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 may 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 Agriculture.

This report is one of four publications presenting the 1998-99 performance of agronomic crops in Georgia. For information concerning the performance of other crops, refer to one of the following research reports: 1998-99 Small Grains Performance Tests, Experiment Station Research Report #659, 1998-99 Canola Performance Tests, Experiment Station Research Report #660, and the 1998 Field Crops Performance Tests, Experiment Station Research Report #658.

The Season

The 1999 corn season was dry and early. March and early April were dry and clear which allowed planting and emergence to progress about a week ahead of average. Dry conditions in mid-April caused some corn acreage to be shifted to other crops and approximately 25% of the corn planted to be in poor condition. Planted acreage was estimated at 300,000 acres representing a 40% decline from 1998. Early May rains improved conditions, but dry weather returned in late May. Tasseling and silking were a week ahead of average, but the dry weather pattern resulted in nearly half of the state's corn in poor condition by mid-June. Scattered rain and slightly cooler than normal temperatures in early July improved conditions slightly. A hot and dry August lessened grain fill.

The severe drought conditions that Georgia has been experiencing since April 1998 continued throughout the corn growing season. Rainfall at the six test sites is listed below. Total seasonal rainfall amount was below normal at all test locations and only 60% of long-term average.

SILAGE TESTS RESULTS

Selection of Corn Hybrids for Use as Silage

J.C. Johnson, Jr., and R.N. Gates

The information presented in the following tables is intended to help producers select corn hybrids that produce large yields of high quality silage. Consistently high yields over several locations and years reliably show a hybrid's ability to produce top yields. Primary quality factors are the proportion of grain and the digestibility of the grain and non-grain portions of the hybrid. Hybrids differ in the proportion of grain they produce.

In the past, it was accepted that a hybrid with the highest proportion of grain made the highest quality silage. Research has shown that, many times, this is not true. In-vitro dry matter digestibility (IVDMD) is a measure of the percentage of a feedstuffs the animal can digest and utilize. IVDMD values for grain are high and do not vary greatly among hybrids. IVDMD values for the non-grain portion (fodder) of the corn plant are lower but much more variable among hybrids compared to the grain portion. Thus, one hybrid with a lower proportion of grain could have high quality (digestibility) because the IVDMD of its fodder portion was much higher than another hybrid having a higher prop 003D ortion of grain but a much lower IVDMD of its fodder portion. 5FEF

Calhoun, Georgia
A corn hybrid for silage performance trial was conducted at this location during the 1999 growing season. However, high wind and rain caused considerable lodging and variation in performance among plots within the test. Since this data could potentially be misleading if used in making decisions concerning hybrid selection, we have chosen not to present them in this publication.

INSECT SCREENING RESULTS

Evaluation of Corn Hybrids for Resistance to Insects

N. W. Widstrom

Environmental conditions in Georgia during the 1999 growing season were unfavorable for buildup of insect populations large enough to cause serious damage to corn. Generally, this damage is greatest in late-planted corn left in the field for an extended period past maturity.

Hybrids resistant to insects are recommended for planting and 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 0.4% to 3.9% and are reflected by VG, G, F, P, and VP ratings in the tables. Hybrids in the tests sustained average yield losses of 1.2%, and 1.9% in the full and mid-season, and short-season hybrid tests, respectively. The mean level of overall yield loss for all tests was 1.6%. Of the total loss, about 34% was attributable to ear injury by the corn earworm, 58% to the pink scavenger caterpillar, and 8% 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 (mid and full-season, and short-season) were planted April 2, 1999. 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 and J. C. Mullis of the United States Department of Agriculture, Agricultural Research Service, Insect Biology and Population Management Research Laboratory, and Georgia Coastal Plain Experiment Station, Tifton, Georgia.
