Jbbies,
Today I planted approximately 10 acres to Forage Perennial Rygrass. Used a Massey Harris grain drill built in 1929, always maintained an used nearly every year. We pulled the drill with my old 1946 Farmall "M".
This is part of our prep work for a new Hazelnut orchard that will be planted in March. It took just a little longer than two hours to do the job.
The ground prep prior to planting was three times over with a heavy cover crop disc, followed by a couple times over with a disc harrow pulling a drag harrow and corrigated roller behind the disc harrow.
Land planed the entire field to level and make it as even as possible considering an orchard is to follow.
Approximately two weeks ago, prior to rain we broad leaf sprayed the field and today following a few days of light rain we drill in 22 pounds to the acre of the grass seed. I would have increased the seed application rate to 30 pounds per acre if broadcast, due to less cover when broadcasting. Whatever you do to cover the seed, use caution, grass seed does not germinate very well if it is not quite close to the surface, at least, that has been my experience at our location.
The drill is equipped with drag cover chains and a single 2X12 drag to follow for extra cover and some leveling.
This perennial ryegrass needs to be in the ground prior to the ground temperature falling below 60 degrees F for maxium germination. As the ground temperature drops, the germination drops. The drill was set at around one inch depth, that is our norm for grass seed in newly worked ground. If we are overseeding a pasture we push the drill culters down fairly hard against the springs and get the seed in by the middle of October here in this part of Oregon.
Hopefully, this will be of assistance to you. This is our common practice with most grass seeds and we generally have very good results unless we get some extremely ugly weather, very heavy rain before the seed germinates and gets some roots established.
