I have on the average 60 3bean pods per plant what is my BPA ..7in rows drilled 68lb seed per ac.

You'll have to get a count of average number of plants per foot On that 7" row to get a very accurate estimate.

Dang guy, he ain't the guru that he thinks he is, get a life!!!!!

It doesn"t work that way to estimate yields.

If it did by your counts you are getting 180 beans for every bean you planted.

Soooo= if you plant a bushel to the acre you would get 180 bushel back by your counts.

No one has come up with a good way to estimate bean yields yet that is consistent.

You can do pod counts and compare one field to other by pod counts but there are to many other variables to get a estimated yield.

Only method I know to estimate bean yields is the SWAG method.

What are you saying and to whom was your statement addressed?

My statement was that to make the yield calculation a guy would have to know how many plants were in an acre.

Stonerock: Figuring the yield estimate on your soybeans does not use the seeding rate you planted. You need to know the actual final stand in the field. The seed beans you bought did not have a 100% germination and the weather conditions effect the surviving plants too.

There are several ways to figure the final stand on soybeans. I use the hoop method. I check my soybeans when they are 3-4 inches tall. I use a 36 inch diameter "hoop". I made the hoop out of 3/4 PVC pipe. I randomly throw/roll the hoop in ten places in the field. I count the number of plants inside the hoop. So lets say I have an average of 27 plants inside of the hoop after ten samples. The area in a 36 inch circle is 1/6165 of an acre. So you multiply the average plants in the hoop times 6165. In this example that would be 27 x 6165 = 166,455 plants per acre.

I mark the plants in several of the hoop circles with a red string around the stem at the base. I just loop it loosely around the base. I then mark the spots with red flags. So I know the average stand at the 3-4 inch stage. I go back and check the plants as the field grows. I modify my population estimate based on the number of live plants that reach maturity/pod stage in those hoop circles.

So I know the estimated population when the plants mature.

With this number I then count the pods on ten plants scattered around the field. I also count the beans per pod on those plants. So with these two numbers I can get an average number of pods and beans per plant.

I take that average beans per plant and multiply it times the plants per acre. This gives me the "beans" per acre.

With that number you then have to estimate the seed size. I usually used 3000 per LBS in a dry year and 2700 per LBS in a good growing year.

This is the hardest part of making an estimate. I check myself at harvest by counting a 1/4 pound of the beans a few times in the fields I estimated the yield in. You kind of learn what the average sizes you grow are.

So that is the long story of how you can estimate the final yield of your soybeans.

I have checked my estimate with the actual final yield across the scales. The estimate is usually within 5%.

JD lost his hula hoop in a bean field

What about that old saying "don't count your chickens before they hatch" ?

Why stress yourself on estimates when the combine tells the tale at harvest and is always right?

you have to admit ,, he gave out statistics and ideas that will give a good estimate . we got enuf peanut gallery folx in c o ng ress

You'd help yourself more by working on your combine to make sure you're getting all the beans in the field as you can influence that but not how many are in the field at this point.

Is that also called the "Crop circles method"?
