How many bushels

of sunflower seeds can you get from an acre?
I am thinking about growing maybe an acre or two for chicken feed and then got to thinking, where in the world could I store them, LOL.
And I was also thinking of possibly growing some to have pressed for fuel oil. Some one posted one post on here where a guy was pressing the oil out and all he was doing was adding about 10% regular gas to it and running in his diesel engines.
It's up over 4 bucks a gallon here now.
Does any one have any figures on bushels per acre???

Thanks
Dennis

I don't know if oilseed and confectionary seed yields are different or not. Sounds like you will be planting oilseed for certain.

Here is a site I got from a Google search. It gives yields in pounds rather than bushels. This site http://extension.missouri.edu/xplor/...ops/g04020.htm shows that 28 pounds is the benchmark weight of oilseed sunflowers per bushel.

This site shows recent Kansas yields: http://kscroptests.agron.ksu.edu/06/06sunflw/6s-map.asp Of the sites listed for 2006 I'm nearest Harvey County. The 2007 yields are considerably less, the Hutchinson site is nearest me and just a few miles away.

Unless you spray for head moth, or whatever it is that badly damages sunflowers, you will need to plant extra to compensate for the loss.

you are going to have to grow and press an aweful lot of seed to get any usable amount of oil.

Thanks Windy in Kanas.
MELOC, I figured I would have to plant even more than what Windy's charts show.
I forget who it was but someone else posted a site on HT where a guy was getting a gallon of oil from a bushel of seeds and mixing 10 to 15%(I think it was) regular gas per gallon and running it in all his diesel engines and getting better mileage and performance to boot.
According to the charts I could get anywhere from 50 to 100 bushels an acre.
I could do a lot of plowing and planting with that many gallons of diesel fuel in a small tractor. Plus I would have the leftovers for chicken feed.
An acre of land is only a 208.7 feet Square and my little 10 HP mower turned tractor is plowing probably 1/4 acre on a tank of gas which I think is a one gallon tank, as it is. A small diesel should do a lot better than that because I have to keep the thing in low gear and the RPM's way up for it to plow now. I could probably run it in 3rd gear or at least 2nd with a 10 or 12 HP diesel engine on it because the diesel engine would run at a lower RPM than the gas engine needs to to make the same HP.
I only problem now is learning how to build a press that would work for getting the oil out of the seeds.
Whatever, I wanted to plant a couple of acres for the chickens this year anyway. The oil, if I get any would just be a bonus.
Wish me luck.
Any one know of a good site for small diesel engines. I have seen a few of them but they are lost now. Sooner or later I will start bookmarking sites when I like them. :baby04:
Thanks again Windy

Dennis

ETA: I am just wondering about it because we could get to where gas is next door to impossible to get plus the price of it is going through the roof.
I just found a 10 HP Hatz diesel with electric start for $2,499 which is way more than I can afford right now for sure. The recoil start is $1,999. But according to the site I read the sunflower oil + 15% gas put out about 40% more power so I may be able to get by with the 7 HP engine. 7 + 40% =9.8 HP.
With the oil I would need about 12 oz. of regular gas to add to a gallon of oil and go.
It's just an idea I have been tossing around inthis empty skull, LOL.

There is a farmer in NW Wisconsin who was in a local paper and on public radio who is growing sunflowers for oil for use in his diesel engines on his farm. He was getting 2000#/A ( a ton per acre) and said that the seeds were 48% oil, and he could extract 76% of the oil with his expeller press setup. so he got about 730# or 105 gallons of oil per acre, plus 1200# of meal with 9 1/2% moisture per acre. I am not sure how many pounds per bushel. He was raising an oil variety of sunflower, but didn't mention the name of the variety, or maybe I missed the name.

I don't recall if he was running straight vegetable oil, mixing it with diesel, but I don't think that he was making biodiesel.

your empty skull does more before 9am than most skulls do all day long...

Thanks MELOC. I just wish I could get my body to do as much as the empty skull does, LOL but thanks for the vote of confidence anyway.

And thanks for the info WisJim. Is there any way you get get me in touch with the guy you are talking about, or maybe find out what kind of sunflowers he grows and where he gets his seed from??
105 gallons of oil would take 10 to 15 gallons of Reg, gas to make 115 to 120 gallons of diesel fuel @ a 10 to 15% cut. That would be enough to work the whole 20 acres behind the house from just one acre of sunflowers. I like that idea. I can ride around on the baby tractor, that's what I will call it, a baby tractor, and plow up 43,560 Sq. Ft and use about 4 or 5 gallons of gas, get my daily work out and get 100+ gallons of diesel fuel for next year, LOL.
Don't we wish it was that easy???
Thanks
Dennis

craft2002--Dennis have you considered powering your tractor with an electric motor and batteries?
