Virginia Corn Performance Tests

The tests reported herein were designed primarily for the evaluation,

under various Virginia conditions, of corn hybrids commercially available in

quantity in Virginia. Included in these tests are privately controlled

hybrids, hybrids developed by state and federal agenci.es, and experimental

hybrids developed by the Virginia Agricultural Experiment Station.

Every effort was made to obtain unbiased comparisons of the hybrids

being tested. An attempt was also made to test the hybrids in areas where

they would be best adapted. The area west of the Blue Ridge has the shortest

growing season, the Coastal Plains area the longest growing season, and the

Piedmont area is immediate between these two and each area has special

problems affecting adaptation of corn. The privately controlled hybrids

which were tested were selected by the companies developing them and they

were tested in the areas desired by the developing company.

Growing conditions during the early part of the season were very favora-

ble at most locations and stands generally were good. However, most tests

suffered from mid-summer drought and all of the Coastal Plains and Piedmont

tests were severely damaged by late SlDJIIIler hurricanes.

Data obtained at each location are given in the tables which follow.

In addition, regional tests which contained the same entries are summarized

by regions.

Experimental Procedure

Cultural practices followed in each test were largely determined by

the cooperator who conducted the test. Pertinent cultural data are included

at the end of the table for each location. All of the regional tests

contaimd 49 entries which were planted in a 7 x 7 triple le.ttice design

with one row plot approximately 30 feet long. All plots were planted thick

and later thinned to as near the desired stand as possible. Seed of

privately controlled hybriC.s ~-;ere obtained dire<::tly from the company de-

veloping the hybriciJand seed of open pedigree corr.mercial hybrids were

obtained principally from certified seed growers.

Data were recorded as follows:

1. Yield - Yields are recorded as bushels per acre of shelled corn at 15-

1/'CJ, moisture. Corrections for stand were made in tests with major stand

variation.

2. Moisture at harvest - Two rows of kernels were removed from 6 to 8 ears

from each replication chosen at random. In some cases ears from two

replications were combined in a single moisture sample taken from these

two replications. The average moisture for each hybrid was used in

calculating its yield.

J. Lodged and broken stalks - Plants were counted as lodged if they leaned

45 degrees or more. Plants were counted as broken only if they were

broken below the ear.

4. Quality of grain - After the corn was harvested from the plot it was

weighed and placed on the ground at the end of the row. Qu~lity of grain

was then rated by visual observation.

Interpretion of Data

Data are reported in estimated order of maturity. Differences in yield

necessary for significance were calculated by the multiple range method, and

all hybrids not significantly different from the top yielding hybrid are

starred.

Although the individual year's data are of importance, particularly to

people responsible for the development ~f hybrids, several years' data are

more indicative of the hybrid's ability to perform.
