2500 to 5500 lbs per acre

The price is per ton, usually about $375 per ton. This is a ton in the hull. The grades are based on Sound Mature Kernel (SMK) percentage. A good peanut grades about 74% SMK, meaning that there are 1480 lbs of nuts in a ton of nuts plus hulls. Of course, this is adjusted based on foreign material and moisture. Kernel moisture is adjusted to 7.5%, but will store at 10.49%. They come out of the field usually in the range of 12 to 16% moisture, after sitting on the ground after digging for two to four days. Some farmers dry their own in drier wagons and 18 wheeler trailers, but usually the buying points do the drying for a fee.

They will grow in clay, at least what I would call clay. Dutch has red dirt out there in west Texas where he grows them, something not even close to sand by our area standards. Honestly, sandy soils seem to grow better flavored nuts. Most of ours go to peanut butter and candies.

[EDIT] Soils need to be well drained. Some of the best coastal plain corn dirt may be poor peanut dirt, but we certainly do have soils that are good for either. The digging/harvest window is a little tight, as you have about a two week period to get 80% of the yield. Digging too early results in poor grade, too late a lot of nuts come off the stems when digging. If on the ground and green, they can usually handle a big rain fairly well intact, but let them sit there for few days, then get stormed on, problems set in.

Hot dry weather in late season can allow aflatoxin to set in. Those nuts may be "hot enough" to have to go to the oil market, usually at a price discount.

Peanuts are very high in oil content, and research is underway to put together a genetics package and production package that will allow for larger amounts of bio-diesel peanuts on our soils. Right now, however, in spite of the "oil yield per acre", the costs are not competitive.
