I picked my corn out of my planter the other day and the wife fed the ears in and I turned the crank on the Fulton sheller so we are done harvesting for the year. The planter is 141 in. X 9 in. and we got 19.875 lb. of 15.5 shelled corn off of it. When I used to get in the corn growers contest a guy came out from a bank to verify the yields so I had my wife--The Fayette Co. Supervisor Chairman watch me like a hawk so I wouldn't cheat. My Son had a leftover part bag of seed corn and when he cleaned the planter out he had some fertilizer left in a barrel so I (borrowed) some of both and when I watered it this last Summer I would spike the water with some of his 28% so my inputs were almost 0 so I think I will make $$$$$. I need help figuring the yields. THANKS---Tee

You have 141 x 9 divided by 144 equals 8.8125 square feet which is 8.8124 divided by 43560 equals .0002 acres. Say 20 lbs of corn equals 20/56 or .357 bushels. So, .357 bushels from .0002 acres is .357/.0002 or 1785 bu per acre......So, you can see that small plots are very inaccurate when trying to determine yield......Either that or you know something we don't know.......

If my calculation are correct over 1700bpa. I thought my 243bpa was good! I really got to move out your way!lol A few years back I had one of those research plot where the rows were like 10 ft long. They came in with a little Gleaner and would do 3 rows stop and weigh it and do 10 more feet stop...
 
Even if you assume your one row would occupy 30 inches of width in a field, it still comes out to over 500 bu/ac.
 
Your calculations assume a 9 inch row spacing, which isn't realistic. Somebody above calculated it on 30' spacing, but its still a whale of a yield. The other unknown is the effect of competition for sun and water once your get inside the field.
 
The way I got it figured there would be room for 4942.97 of these planters per acre so if I work real hard in the shop this winter and build 49,429 of these(enough for 10 acres) and get a little help I could get rich with $3 corn!!! I remember years ago when Herman Warsaw out of Indiana broke 300 bpa in the national corn growers contest and I thought that was good.---Tee
 
That is why I said small plot yields are very inaccurate and do not reflect field conditions. What if you had one plant of corn in a 6 inch pot that grew 2 ears....Ben
 
Neighbor has one of them F.I.R.S.T plots and they had a little Gleaner out there 3 weeks ago doing it.---Tee
 
Didn't do any calculations at all ..... just read the posts below, I go with 1700+ bpa, that's my answer !!!
 
Albeit you cheated a little by planting against a white wall and hand fertilizing with every watering, it's interesting to see what today's hybrids are capable of under ideal conditions.
 
Much the same situation that we use in the raised beds in out garden. We have 4 4x12' boxes that we plant sweet corn in. 240 seeds per box. (Population adjusted per acre 212,000/A).
We harvest about 220 nice ears per box, each year.
