Greengrazer V Sorghum-Sundangrass (Sorghum bicolor x Sorghum bicolor)
Small-seeded and thin-stemmed type
Dark green color with Green
Top trait
Anthracnose and Downy Mildew resistant
Greengrazer V is a new
small-seeded three way cross with thin stems
that are highly palatable. Regrowth after cutting
is very fast. Greengrazer V is a dark green color
and also possesses the Green Top trait, which
allows for further extension of the plant. Planting
Greengrazer V at higher populations per acre will
result in a finer stemmed forage. Finer stems
will
allow the forage to dry faster for higher quality
hay than is possible with thick stemmed
types.

Soil Temperature:
Warm (60 F)
Water Requirement:

Seeding:
Soil temperature should be at least 60 F
Greengrazer
V is usually planted between June 10 and July 10
in the northern states.
Can be no-tilled
into the stubble of
winter and spring crops.
Planting
depth should be 1”.
Do not plant in soils with pH greater
than 7.5 to 8.0. Chlorosis will be a severe problem.
Harvest:
Greengrazer V is usually harvested
63-65 days after seeding.
Protein will
decline as harvest is delayed, but energy
will increase upon heading due to continued
sugar formation in the sorghum stalks
and leaves, and carbohydrate deposition
in the developing grains.

Strengths
High yield potential.
Thin-stemmed plant type.
Small-seeded type.
Dark green plant color.
Green Top trait
(further extension)
Good overall disease resistance
package.
Resistant to Anthracnose and Downy
Mildew.
Sweet juicy midrib.
Weaknesses
Moderate drought
tolerance.
Poor storage–juicy midrib
favors bacteria.
Avoid Nitrate and Prussic
Acid Poisoning from sorghum:
Avoid large nitrogen
applications prior to expected
drought periods.
2,4-D can increase Prussic Acid concentration
for several weeks after application. Do not harvest
drought-damaged
plants within 4 days following
a good rain. Do not green chop within
7 days of a
killing frost. Cut at a higher stubble height,
nitrates tend to accumulate in the lower
stalk. Wait 1 month before feeding silage
to give Prussic Acid enough time to escape.
