The first thing I would ask is are you furrow irrigating or overhead irrigaing?
Most irrigation here is furrow on 38-40" rows. There are a few guys that I have seen taking half of the gangs off of their hippers or middle busters(there are also some one pass tillage tools that do this) and are making a wide bed...76-80". This will give you the weed contol benefits of drilled beans while still giving you a furrow to water down. I intend on planting my wheat on a raised wide bed this fall, assuming I can get back in the field after this hurricane, and will plant with a 1560 JD drill. I will follow the combine with the same drill with soybeans on this wide row. If you are watering with a center pivot, I defer to someone with more experience.
I am watering with a center pivot. I was thinking of planting roundup ready beans with a drill and I would have a set of tracks every 60 ft. where I run my sprayer. I had heard of sowing the beans to thick and would not produce; not any beans in this area.
I'm no expert sb farmer but the rule of thumb I have heard from "good" sb farmers is to increase population the later you get in the season as beans won't get as tall. Not sure what the optimal populaion # would be for your area.
I agree the only reason not to plant too thick is it creates weak plants that lay down easily. But if the second crop is not expected to make full height because of season length I'v seen recommendations to put em on a little heavier. I would check with other growers in your area and search the Oklahoma State ag department information. I think you might be in a zone that is more prevalent for "Rust" which should be considered with late season beans.
We go a little later than that in Ohio. Here in SW part of state I see fewer try it since we seem to miss needed july showers too often. There on wheat field up the road from me and he only got about a 30% stand. Check with local experts! Are there any on here?
Wheatfarmer,I used a 7200 JD planter equipted for no-till.
The beans we planted convential all look good, the beans I no-tilled in wheat stubble just about all died in the 100+ degree heat, the convential tilled beans wilted some but did not die.
A neighbor no-till drilled in wheat stubble he got an excellant stand.
We are not irrigated.
I have a trucker who will take all the alfalfa at 160 to 170 ton when ever I am ready to start loading it. The beans I will no till after wheat will be irrigated on the ground I have rotated out of alfalfa. I have been trying to raise something on this irrigated ground that would make close to what alfala would. I have gotten use to having that second crop around and don't what to have only wheat.
