FORAGE PRODUCTION FROM SUGAR SORGHUM, FORAGE SORGHUM
SORGHUM X SUDANGRASS HYBRIDS AND MILLETS AT ONA ARC: 1983
R. S. Kalmbacher, D. L. Wright and F. G. Martin-
Sorghum x sudangrass, forage sorghums, and millets may provide valuable
supplements to perennial grasses during periods of feed shortages when
fed as green chop or stored as silage. Some forage sorghum hybrids may
produce more dry matter per acre than corn, however, digestible energy is
usually lower in sorghum. Sugar sorghums have good potential for forage as
well as for producing a fermentable carbohydrate for ethanol production.
It is important to determine adaptability and productivity of new
sorghum hybrids and millet varieties being released by public and private
plant breeders. It is necessary that varieties be tested under south-central
Florida conditions such that growers can have the best plant material
available. The purpose of this publication is to present comparative data on
entries tested at the Ona Agricultural Research Center (

Methods and Materials JUL 1
Twelve sugar sorghums, 18 forage sorghums and 15 s VFh !k UMhVgif**Mj
were seeded at 8, 10, and 10 Ib/A, respectively, in 30 inch rows.
pearlmillets, one Japanese millet and one sudangrass variety were drilled in
6 inch rows at 6 Ib/A. Crops were seeded on 7 April 1983, but due to
excessive rains the experiments were reseeded on 18 April. All four
experiments were randomized, complete blocks with four replications.
Fertilization consisted of 35 and 70 lb/A of P205 and K20, which was
disked into the seedbed on 6 April. When the experiment was reseeded, no
additional fertilizer was applied. On 28 April, 80-40-40 lbs/A of
N-P,0 -K20, respectively, was top dressed on the seedlings after emergence.
On 23 May sugar and forage sorghums and sorghum x sudangrasses received
90-45-45 Ib/A when plants were 16, 30, and 36 inches tall, respectively.
Sugar sorghums received 50-50-50 lb/A immediately after harvest 1 on 6 August
and 60-12-60 lb/A on 20 September. Forage sorghum received 50-50-50 lb/A
after harvest 1-on 21 July and 50-10-50 Ib/A on 16 August. Sorghum x
sudangrasses received 50-50-50 lb/A after harvest 1 on 28 June and 60-60-60
after harvest 2 on 6 September. Millets were fertilized with 50-25-25 lb/A
after harvest 1 and 60-30-30 lb/A after harvest 2.

Florida.
Herbicides were not applied pre-or post emergence, but paraquat was
applied at 0.25 Ib/A post-directed to forage sorghum on 13 May. Sugar
sorghum and sorghum x sudangrasses were hoed on 13 May. On the same day of
each harvest of sugar and forage sorghum and sorghum x sudangrasses, paraquat
at 0.25 lb/A was broadcast over the stubble. Furadan 10 G was applied in the
row at seeding at 2.0 lb/A active.
The crops were irrigated with an over head sprinkler system, and 4.2
inches of water was applied between 5 May and 24 May.
Percent dissolved solids (sugars) were measured with a hand-held
refractometer and readings were taken on the day of harvest. A single stalk
was taken from each plot and juice was extracted from the center internode.
All readings were corrected for temperature.
Results and Discussion
Sugar Sorghum
There were significant differences in dry matter yields of the thirteen
varieties tested (Table 1). Yield ranged from 6.9 to 17.8 t/A and averaged
12.3 t/A. Two harvests were made and average yield at the 6 August harvest
was 8.3 t/A and 3.4 t/A at the 16 November harvest.
The higher yielding varieties tend to be later maturing, such as Mn 1500
and M81E which were 90 and 79 days to anthesis, respectively (Table 2).
Lower yielding entries, like Ramada and Sucro Sorgo 301 were early maturing
and were 59 and 55 days to anthesis, respectively. In spite of the later
than normal seeding date the sugar sorghums were slower maturing than other
sorghums. The first crop required 110 days and the second 97 days.
Significant differences in percent dissolved solids were found among
varieties (Table 2). Varieties that contained a greater solid content at the
first harvest were not necessarily greater in solid content at harvest 2. At
both harvests content of solids were similar with 15.1% at harvest 1 and
14.6% at harvest 2. Early and late varieties tended to be lower in solid
content with mid-season maturities tending to be higher in solid content.
Lodging was not a problem with any variety (Table 2). This 1983
experiment was planted on land that had been fallow for one year. This
apparently reduced lodging due to the disease, Phythium, of sorghum which has
been associated with diminution of the entire root system.
The varieties, Mn 1500 and M 81 E, seem to be better yielding varieties
at Ona ARC (Table 3). Poor yielding varieties were Brandes, Rio, and Ramada.
These results have been rather consistent over three years of testing.
Average annual yield ranged from 4.4 to 13.2 t/A in 1982 and 1981,
respectively, which demonstrates that great variation in yield can occur from
year-to-year (Table 3). In 1982 poor yields were attributed to the site
where the experiment was grown. This site had a 5-year cropping history of
sorghum and a single, poor harvest resulted. In 1981 and 198 Crops were
planted on land where sorghum had not been grown the previous year.
Forage Sorghum
Significant differences in the dry matter yields of 18 forage sorghum
hybrids were found (Table 4). Yield ranged from 8.2 t/A (McCurdy F 75) to
17.4 t/A (Pioneer 911) and averaged 12.2 t/A after two harvests.
The two harvests resulted in 94 and 95 day growing periods,
respectively. Time until crop maturity was found to vary greatly (Table 5).
Pioneer 911 never matured beyond the vegetative stage, but all others were at
the dough stage at both harvests. Late maturing varieties were Pioneer 927,
Pioneer 923, Funks HW 5574, and early varieties were Dekalb FS 5, McCurdy
F-75. There was some question concerning Pennington Pennsilage because in
past years this was a late maturing, high yielding entry, but not in the 1983
test.
Lodging was not a problem with most varieties, but McCurdy F-75 and Hunt
Terra Silo Xtra had 55 and 54% lodging, respectively, at harvest 1 (Table 5).
Grain yields were related to varieties with Dekalb FS 25 A, Fla Feed and Seed
Gator Chop A, and Pioneer 947 being the best yielders. Grain yields were not
measured on all varieties, but these three produced 2770, 2250, and 1760
lbs/A of oven-dry grain.
Better yielding varieties and those with desirable characteristics for
south central Florida were Dekalb FS 25 A, Northrup King 367, Pioneer 947 and
Pioneer 923 (Table 6). Although Pioneer 911 is very high yielding, it did
not produce grain and may have lower feeding value.
Sorghum X Sudangrass
Of the fifteen hybrids evaluated Dekalb SX 17 and PAG Honey Chow (14.1
and 13.7 t!A, respectively) were significantly higher in dry matter yield
(Table 7). Yield ranged from 7.1 to 14.1 t/A and averaged 10.5 t/A. Three
harvests were made, and yields at harvest 1 and 2 were 4.6 and 4.0 t/A,
respectively, and 1.8 t/A at harvest 3. The 1983 growing season did not
provide excessive rainfall in mid-summer, and three excellent crops with
fairly consistent harvest yields resulted.
As compared with sugar and forage sorghums, the sorghum x sudangrasses
can be ensiled much sooner. The three crops of 1983 required 71, 70, and 66
days. Lodging (and disease) were not a problem at any harvest in 1983 (Table
8). The rapid growth and reduced probability of lodging could give this crop
an advantage over other sorghums.
Recommended varieties for south central Florida are based on at least 3
year's testing (Table 9). McCurdy Sweet M, Dekalb SX 17, Northrup King
Sordan 79, Taylor Evans Haygrazer, Gold Kist Unigraze, Fla Feed and Seed
Gator Grazer and Pennington Summer Grazer are all recommended.
These were evaluated for silage making, but would also be excellent for a
high quality spring hay crop or for grazing when harvested at 30 to 36".
Millets
The pearlmillets Tifleaf 1 and GAHI II were longer living, higher
yielding entries than any entry tested (Table 10). These were very early
maturing entries with good vigor and have the ability to establish a canopy
quickly. Japanese millet was also a good yielding crop and would be
excellent for a single grazing or hay crop. Seed is quite inexpensive for
Japanese millet as compared to other millets or sudangrass.
Millet crops were quick to establish as the 1st, 2nd and 3rd crops
required 39, 18, and 21 days to produce. The crops were not persistent
(except for Japanese millet and sudangrass) because high water levels from
summer rains reduced stands. Weeds were'a problem because there are no
herbicides which provide control. A rancher should select a multi-graze crop
which forms a good canopy quickly (Tifleaf I) or a single-graze crop which
also competes well by completing its life-cycle quickly (Japanese millet).
Both crops had good canopy cover at harvest 1 and 2 (Table 11).
Conclusion
On the basis of testing in 1983 and previous years, the following
varieties or hybrids are recommended for south central Florida. These
entries were consistently higher yielding, persistent and relatively free of
problems such as lodging.
