Primary Uses: |
Grain |
|
Planting: |
Plant between April 15 and May 10 in
Ohio. Plant to a depth of 1.5 to 2 inches. |
|
Seeding Rate: |
Actual seeding rate depends on the
variety, soil type and yield goals. Most varieties yield best
between 22,000-30,000 plants/acre. A general figure often used
is 26,000 plants/acre. |
|
Fertility: |
Soil pH should be at least 6.5 or above.
Corn uses large amounts of Nitrogen. The total amount applied
depends on yield goals and overall management. For 120 bu/acre
yield, about 140 lbs. N/acre should be applied. For 160 bu/acre
yield, about 190 lbs N/acre should be applied. Depending on
economics of application, it is best to apply N in split
applications, with a small amount at planting and the remainder
sidedressed before the 10 week after planting. Application of
P and K should follow soil test recommendations. |
|
Insects: |
Insects causing problems at germination
include seedcorn maggots, cutworms, grubs, and wireworms. The
European Corn Borer affects some fields from growth stage V8 and
on. Corn rootworm may also cause problems evidenced by lodging
at growth stage V12. Japanese Beetles may clip silks causing
lowered pollination. Aphids rarely cause economic
losses. Second brood European Corn Borers can be a problem by
feeding on developing ears. The most economical control is
selection of resistant varieties. |
|
Diseases: |
Common Stalk Rots include Anthracnose,
Giberella and Fusarium. Leaf Blights include Northern Corn
Leaf Blight, Grey Leaf Spot and Stewart's Wilt. Virus diseases
affecting corn include Maize Dwarf Mosaic and Maize Chlorotic
Dwarf. Ear and stalk rots occurring commonly in corn include
Giberella, Diplodia and Fusarium. The most economical control
is selection of resistant varieties. |
|
Harvest: |
Normally not harvested as a commercial
crop. Hand shelling is recommended. |
|
Comments: |
Pod Corn is considered a precursor to modern
corn. Each grain is enclosed in an individual
husk. TCS
