I was thinking about hand throwing clover between the corn rows. Will it get enough sun to germinate? Will it not germinate until the corn has been cut?
I think clover would be difficult to establish, I think a brassica would be better I'd it can get enough sunlight.
Time it so that the corn is yellowing and drying down and you'll be fine. Harvest won't be far off and it'll have a head start. People have been planting crimson clover at layby (about two-three feet tall) and having good luck with it booming after harvest.
I have had tremendous results with overseeding turnips, brassica, and radish into my corn, but it all depends on the distance between your rows. I will take some pictures next time I am at one of the properties that I have done this on for your reference.
Here is a photo of some radish/brassica/turnip I overseeded into my corn last season. As you can see it did quite well, and I am sure the starter fertilizer and urea gave the plants a real kick start!
Regularly use clover between the corn. I plant in early August and by the time the corn is cut in late September the clover is ready to go crazy when the extra sun hits it.
Interseeding cover crops into V5 corn | Integrated Pest and Crop Management "All cover crops were successfully established. Within four weeks of seeding all cover crops had germinated, had consistent growth during the growing season, and had good vigor up until two weeks of grain harvest. The corn never showed any visible symptoms of stress and the cover crops did not significantly reduce corn yields. Radish had the most above ground biomass at harvest. Radish and oat/pea all winterkilled. Red clover did not survive the winter. The red clover looked very poor at the time of corn harvest; the late corn harvest stressed the red clover too much for it to survive the winter. All cover crops were completely buried by the corn residue after harvest, but winter rye still survived the winter."
We plant our food plot corn with a 4 row planter, that has 3 corn meters and 1 soybean meter on a outside row. When you go down and back, it leaves you with 2 rows of beans, 6 rows of corn. The 2 rows of beans allow access to broadcast fertilizer and brassicas into the 6 corn rows from both sides. And also allows enough light to get in the corn for the plants to grow under the corn canopy no matter how tall the corn is. We have extremely high dpsm so the beans stay clipped down making it easy to drive through with our front mount moultrie spreader on our 4 wheeler. Clover is very tough to get established mid summer, I would not waste my time!
