soybean seed

They sell a 140,000 seed bag these days, used to be a 50# bag.

Folks drill in beans at 200,000 - 240,000 per acre on the heavy side, or plant with a corn planter at 130,000-180,000 per acre.

So, roughly a bu an acre, could be less depending on how accurate your planter is and if you want to get to lower populations.

I plant 140,000 or at least I try to get as close as possible to that, I plant in 30 inch rows. And I've been using a navy bean plate but I have a set of pea plates that has individual cells and I going to try them so I can end up with a better spacing. jus my 2 cents. john
 
I shoot for a population of 150,000 planted. When I do milo (I usually do a 40 or so - I use bags for that) I figure it out with the population I want and then buy 10% more. I use the bulk bags for beans so I haven't worried about them n bags in quite a while.
 
The later you plant, the more beans you should put in, to get a 140,000 population. What spacing are you going to use? going with a 7 inch drilled spacing, you won't get the beans to branch out much. a 15 inch spacing seems to be the best spacing for me, for yield. IF I go with a 30 inch spacing, it seems I also have late weeds popping up.
 
lots of variables ,,weather is biggest wild card ,.. you are safe atone bag to acre ,,. however,i try to plant around 170 -180 k per acre,. and end up around 150-165k ,. like others state, seeded thru a corn planter will germ better ...
 
must be different where i live. I shoot to plant 120,000 and have for years. I plant 15in rows with a case ih drill with planter units on it. mother nature controls how good the beans are. the later i plant, i make sure they go into moisture. I always plant 1.5in deep, now. learned my lesson years ago when i hired them planted by a JD 750 no till drill. the guy came late and planted them. planted them like 250k but ground had dried out and they never came up. always made sure they were in moisture after that. didn't learn my lesson on the 750 no till drill until the next time i hired it done. wound up with a planter filling in all the blank spots!
 
Several questions. Do you have sandy ground, good non crusting loam or hard crusting clay? The non crusting loam you can get by with a lot less seeds than the crusting type as the crust will kill a lot of plants that cannot break thru the crust. The closer together the seeds the more power they will have to break thru that crust. Also a rotary hoe at the correct time will help that emergence thru a crust. So there are a lot of variables to think about even befor you start to think drill with 7" rows, newer drill on 10" rows, planter on 15" rows, planter on 20" rows, planter on 30" rows or planter on 40" rows. Then are they a straight line bean or a bushey type bean, straight line requires half again as many seeds as the bushy type. Older grain drill will require twice as many seeds as a corn planter on wide rows.
