1994 Florida Soybean Variety Trials


Introduction

In 1994, soybean variety trials were conducted at five locations in
north-central and west Florida (see map). These trials were designed to
evaluate yield, agronomic characteristics and nematode resistance for
maturity groups (MG) IV, V, VI, VII and VIII. Five categories of variety
trials were conducted in 1994.

1) A variety performance trial planted on June 29, 1994
consisting of 45 entries, was evaluated for yield potential.
The site of this trial was at NFREC, Quincy, on a field
without nematode pressure.

2) A variety performance trial planted on July 15, 1994
consisting of 45 entries, was evaluated for yield potential.
The site of this trial was at NFREC, Quincy, on a field
without nematode pressure.

3) A variety performance trial consisting of 39 entries grown on
soils infested with southern root-knot nematodes at the AREC,
Jay.

4) A variety performance trial consisting of 39 entries grown on
soils infested with peanut root-knot at the Davis Brothers'
Farm, Santa Rosa County.

5) A variety performance trial consisting of 39 entries grown on
soils infested with a low level of race 3 soybean cyst
nematode at AREC, Jay.










Methods


The experimental design for all trials was a randomized complete
block with four replications. Row widths were from 30 to 36 inches.
The experiments were analyzed using analysis of variance, and Duncan's
Multiple Range Test or least significant differences (LSD) at 0.05.

Planting rate was nine seeds per foot of row (12 seeds per foot for
the late planted trials). Plots were planted using plot planters.

Yield was determined from the middle one or two rows except when
stands or plants were weak on one side of the plot, in which case,
border rows were used. Harvested area was generally between 80 and 96
square feet. Grain was stored for a short time under uniform moisture
to obtain the same moisture for all samples. Yields are reported as
bushels per acre (60 lb/bu) at 13% moisture.

Maturity date was when more than 95% of the pods had their mature
color.

Height was the average distance (inches) from the ground to the tip
of the main stem at maturity.

Lodging was rated at harvest using the following scale:

1 Almost all plants erect
2 All plants leaning slightly, or a few plants down
3 All plants leaning moderately, or 25-50% of the plants
down
4 All plants leaning considerably, or 51-80% of the
plants down
5 Almost all plants down

Shattering was not rated because of infrequent occurrence.

Root-knot nematode galling index was determined to evaluate damage
by root-knot nematodes.

Percent of Root Surface Galled

0-4
Scale
None 0
Trace <5% 0.2
Trace 6%-25% 1.0
26-50% 2.0
51-75% 3.0
76-100% 4.0

Cyst nematode resistance was determined by yield comparisons on
yields of soybeans grown on field with a low level of soybean cyst
nematodes.










New Techniques in Soybean Production


There are several ways to reduce production costs of soybeans that
have not been widely used including the following:

1. Use of strip tillage or no-till with a drill where irrigation
is available.

2. Trap cropping This involves planting 8 to 12 rows of a group
IV soybean around the perimeter of the field. These group IV
soybeans are indeterminate and insects seem to migrate to them
rather than the entire field. This method is especially good
for stinkbugs which tend to migrate from fence rows and
adjoining crops. Insects may be controlled by spraying a
single application of insecticide on the group IV soybeans.
Frequent scouting is necessary. The group IV soybeans
recommended are NK S4884 (a tall variety with cyst race 3 and
moderate southern root-knot resistance) and DP 3456. These
varieties yield well and have good seed quality.

3. Weed scouting and using the Herb computer program, which
determines the best post emergence herbicides at the least
cost. Scouting at 7 to 14 days after emergence to determine
weeds present is a key.
