........so ,you just broadcast on mud??Jap millet produces a lot of ducks in the south. Short maturity date - less than 60 days. Seed straight on a mud flat if you can. I have not seen much reseeding. Chiwappa millet does better at reseeding - but I have been unable to provide a seed source. Browntop will lay down shortly after maturity and Jap will stand a fair while. Jap will also keep growing if the water comes up on it a few inches.
I have seeded Jap Millet onto exposed mud with good success. I also had great luck using Rex rice. Presoaked for 24 hours, pulled straight out of the soak and broadcast onto wet bank/mud flat. I planted the rice too late to get a good head on it. Should have done it early June. Best success was spraying the high grass/smartweed in some areas, letting it die and lay down, then broadcasting the Jap millet into that THICK thatch. The seed is so small that it easily gets down to the soil and did great. That's when I found out what armyworms were!
Yes. I plant by broadcast about 2 weeks after spray. The grass usually just lays down by then.Army worms are the scourge of duck plantings because the are usually growing good and are nice, green, and succulent when army worms are at their worst.
So - I have a couple areas with thick smartweed, still has some water standing. If summer heat ever shows up and if it quits raining - these areas may start drying out - but not soon enough to plant with conventional tillage. But, I am extremely interested in your method. How long after spraying do you broadcast the seed. You did nothing but spray and then broadcast?
