How and when do you try to predict yield in beans ?
This is my first year with beans so I really have no idea.
Bean are dryland, 10" rows, around 3' tall with what appears to be alot of pods but idk. Everyone around here says beans will be good this year but nobody makes a guess.
I assume I need to count pods/plant and beans/pod

52272 feet of row on 10" equals 1 acre, count pods , you can skip the pods, just count the beans per plant on 52272 feet of row then divide by about 200,000 in case they are small. that should give you bushels per acre. let us know how it turns out.

There are two sure ways and one other.
the sure ways first
1) immediately after combining measure the bin ...it will be 10% less than the same measurement of corn, then divide answer by # of acres = Y/acre
2) immediately after combining them add up all scale tickets, divide by acres = yield/acre
third way
1) just guess at it like everybody else does. If it makes you feel better (will not make any difference in the end) count plants, count pods, and count beans in pods, then divide by the square root of your age then use the X factor (any # you are partial to) put them together for a fort night. Sprinkle with fairy dust then divide by two. (three if expecting triplets) vf

I have had lots of people ask what beans will yield. Always one of two answers: between 20 and 70 or we will now when we get rolling. The seed size is a major factor in yield. Almost like corn is this year...that's another deal for another day. If anyone figures out a way to guess halfway close, fill me in

1 On 10 inch rows , you need to measure off 52 feet 3 inchs
2 Count the number of plants in different spots in the field , they like to see 10 different spots.
3. Count the number of podsper plant on 10 randomly selected plants from each sample . Calculate the average
4. Calucuate pods per acre by multiplying plant pop's by pods pre plant .
5 Calculate seeds per acreby multiplying pods per acre by an estimimae of 2.5 seeds per pod
6. Calculate pounds per acre by dividing seeds per acre by an estimate of 2900 seeds per pound.
7. Estimate yield by dividing pounds per acre by 60 pounds per bu.
Thats all there is to it , good luck , Ken

Ok I went out to count beans on 52272' of row but I ran out of fingers and it turns out my row is not that long...so i guess i will resort to not worrying about it and see with the combine. That seems a lot easier any way and then I'll add 13.7645839% and that's the # I will tell everybody.
What a bunch of smartasses

Ya, don't even try to estimate soys. I've tried every method out there and it went from madenning to plain ol' frustrating.
As someone else said, they will be between 20 and 80 (we get some 70's on a good year).
If you really want, hand harvest 1/10 of an acre (4356 sq ft) shell them out by hand, adjust for moisture, and multiply by 10.
Don't like that method?? "Here" I count the pods on 10 plants, average them, and my "very rough" rule of thumb is 1 pod = 3/4bu/ac. That should get you in the ball park.

Estimating won't make a bit of difference in what you harvest so why don't you just wait until you harvest and then you'll know.. If you've already sold too many, the estimate won't make any difference. If you want to sell, it's just a guess anyway.

Estimating beans is not all bad , I have done it and get some good info from it in test plot work where compareing different fungicides and insecticides plus feeds !
If you take the time to do it and doit right it really does work FOR the time you do not the future .
One year had 80 acres in field plots in 80 rod rows , check strip was 70 bpa
each strip got better and better showing what we did , did help BUT that year in Aug. we only got 2 tenths of an inch , the strips all most were the same in yield = you just need rain , lol Ken

I'm guessing you're in NC Kansas not far from the Nebraska border and you have beans that will blow your mind. We were in NC Neb yesterday and stopped and picked a plant or two. Just freaking unreal is all I've got to say about the beans up there. Do the ECI check and let us know what it is. I won't post what I counted cuz being called a liar is kinda hard on the ol' self esteem. lol. |

I'll do some checking using his formula and see what I get. |

From a distance I would say your beans will outyield the corn down here in the south end of the state. All you need to do is have beans in the 20s to do that.

ask your neighbor what his made then add 3-5, that how they do it around here.
I can usually get within 10-15 bushels of getting it right.

If the plants are healthy and three or more beans per pod we just count each fully developed pod as one bushel. If it is not as healthy as it should be, small seed size, stressed then count each pod as 2/3 of a bushel. Most of the time it usually gets you close but then again sometimes it don't but it is a fun game to play!  |

Thats all there is to it , good luck , Ken Ken did you happen to miss a step in the formula? Don't you have to multiply by 1000 in there somewhere to get plant pop./acre It appears I have a pop. of about 115,000 with 40 pods per plant so that gets me around 66 bu/acre right? I'll believe that when I see it on the scale tickets. Did I go wrong with my figures ? Thanks |
