I just had a look at the latest Pecan South magazine. In it were statistics regarding pecan production for several states from 200-2011 as well as forecasts for 2012. How did Mississippi fare?
In terms of Improved variety production, Mississippi had 2.3 million pounds in 2009, 1.4 million pounds in 2010, and 3.4 million in 2011. Native and seedling production were far less with 700,000 pounds in 2009 and 2010, and 1.6 million pounds in 2011. As you can tell 2011 was a pretty good year for pecans in Mississippi with a total of 5 million pounds.
Price per pound in 2009 was $1.15 (improved) and $0.65 (native/seedling). In 2010 it was $1.60 and $1.10. In 2011 it was $1.80 and $1.40. The prices continue to climb.
The overall production value in Mississippi for pecans in 2009 was 3.1 million dollars. In 2010 it was 3.01 million dollars and in 2011 it was 8.36 million dollars.
Estimates for 2012 have the crop somewhere between 2 and 2.5 million pounds. This is somewhere around average production, but with good prices it may be worth looking into renovating some of those old orchards. Here is a publication with some tips to get native and seedling orchards back into shape: http://msucares.com/pubs/publications/p2722.pdf
