1970 FORAGE AND GRAIN SORGHUM PERFORMANCE TRIALS IN FLORIDA

Cooperators:

L. S. Dunavin, West Florida Station, Jay (B)*
M. C. Lutrick, West Florida Station, Jay (G)
R. W. Lipscomb, North Florida Station, Marianna (G)
R. L. Stanley, North Florida Station, Quincy (B)

In 1970, grain sorghum performance trials were conducted
at Jay, Marianna, Quincy, Gainesville, Belle Glade and Homestead.
Similarily, forage sorghum trials were conducted at Jay, Quincy,
Gainesville and Belle Glade. Trials were conducted on mineral
soils except at Belle Glade where a muck soil was used. This
report gives the results of these trials plus summaries of similar
trials in recent years.


GRAIN SORGHUM TRIALS

In all trials, the varieties were replicated 6 times in
a randomized block design. Yields and other data reported at
each location are average for the 6 replications. Plots were
either 16 or 17 feet in length, with 36 or 38 inches between
rows. One-row plots were used at Gainesville and Jay, and 2-
to 4 row plots were used at the other locations.

Fertilization rates varied slightly at different locations.
Soils and fertilization rates used at each location are given in
Table 1. All entries in the trials were seeded at the rate of 10
pounds per acre except at Gainesville where 10 live seeds were
planted per foot in drill of rows 36 inches apart. Seeding dates

for the different locations were: Jay, April 6; Marianna, June 8;
Quincy, July 7; Gainesville, April 17; Belle Glade, May 1; and
Homestead, April 23.

Grain Yields

A summary of the grain yields for the first harvest (seed
crop) of entries of the 1970 trials at Jay, Marianna and Gainesville
are recorded in Table 2. Grain yields for Quincy and Belle Glade
are presented in Table 3. Yields at Quincy were affected by the
lateness of seeding, sorghum midge and birds and at Belle Glade by
birds, so they are of little or no value for recommendation purposes.
No grain yields were taken at Homestead because of depredation by
sparrows and other local birds. No ratoon yields were taken at
any location during the 1970 season.

The grain yields of sorghum entries grown more than one of
the three years, 1968-70, are presented in Tables 4, 5 and 6 for
Jay, Marianna and Gainesville, respectively.

Plant Characteristics Other Than Yield

Disease, lodging and bird damage ratings plus plant height
and relative maturity for hybrids in trial at Homestead are reported
in Table 7. The days from seeding until 50% bloom and disease
ratings of hybrids for trials at Jay, Gainesville and Belle Glade
are given in Table 8.

The plant height at Jay, Gainesville, Belle Glade and Homestead
are listed in Table 10. Head types and ratoon regrowth ratings
are reported in Table 11. Ratings of bird damage to varieties in
trials at Jay, Belle Glade and Homestead are presented in Table 12.

Summary of Grain Trials 1968-70

Table 13 shows the yield performance of the various varieties
in Florida trials during the three-year period, 1968-70. This
table allows one to determine the number of trials in which the
grain yield of a variety was above the average yield over all entries,
and the number of trials in which the variety was one of the 5
highest yielding varieties. Three time periods are given in the
table, 1968 through 1969, 1970 and 1968 through 1970. A trial
had to have 12 or more entries to be included as a trial. The
grain yields for the 1970 trials are reported in Table 2.

Grain Sorghum for Silage

The leaf, stem, head and total yield of six grain sorghum
hybrids at Jay for the first harvest are presented in Table 14.







- 3 -


The plant heights in Table 10 can be used in estimating relative
silage yields. Usually the taller varieties produced more forage
(leaves and stems) than did shorter varieties. If the highest
quality silage is desired, one should select a short hybrid with
high grain yield. For highest silage yield select a hybrid which
is tall and has high grain yield.


FORAGE (SILAGE) SORGHUM TRIALS

The fertilization rates and soils for the forage sorghum
trials at the various locations are recorded in Table 1. The
rate of seeding the varieties in all trials, except Gainesville
was 10 pounds per acre. At Gainesville 10 live seed were planted
per foot in rows 36 inches apart. The Florida 200 A corn population
varied from 13,000 to 15,000 plants per acre. Seeding dates for
the different locations were: Jay, April 6; Quincy, July 7;
Gainesville, April 23; and Belle Glade, May 1.

Hybrid forage sorghum varieties were arranged in a randomized
block design replicated six times in all trials. Three of four-
row plots, with all measurements made on the center row or rows,
were used at most locations. Plots were 12 to 20 feet in length.
Distance between rows was either 36 or 38 inches. At Belle Glade
plots were 2 rows 16 inches apart and seeded in closely clipped
common bermudagrass sod. Insecticides and herbicides were applied
as needed to control insects and weed pests. The principal weed
control at most locations was from cultivation.

1970 Forage and Grain Yields

The dry weight and freshweight forage yields are reported
in Tables 15 and 16, respectively, for Jay, Quincy and Belle-
Glade. The trial at Gainesville was not harvested as a severe
local storm caused 100% lodging of all entries just prior to
harvesting. Grain and ratoon yields of leaf, stem and head
percentages for the trial at Jay are given in Table 17.

Summary of Forage Yields 1968-70

The head and total forage yields for the period, 1968 through
1970, are reported for Jay, Quincy, Gainesville and Belle Glade
in Tables 22, 23, 24 and 25, respectively. Only two of the three
years data were available at Quincy and Gainesville.

Table 26 shows how many times a forage sorghum entry has
been in Florida trials during the period 1965 through 1970. Also
given in Table 26 is the number of trials where the forage and
head yields of an entry was above trial average and one of the top











five highest yielding entries in a trial. The dry matter yield
of total forage and heads was used in ranking varieties except in
trials where only green (fresh) weight yield was measured.


Widely adapted and superior yielding varieties should yield
above trial average in a high percentage of trials in which they
are tested. As varieties with the highest head (grain) yield are
not usually the varieties with highest total forage yield, one
should decide whether total forage yield or head (grain yield)
is most important and use the appropriate table in selecting superior
yielding varieties.

Sorghum Trials. Save this report if you will need
