The calcium requirement for large-seeded runner peanut cultivars is higher than we expected, and we had numerous calls concerning the level of “pops” and pod rot in Georgia-06G, Florida-07 and Tifguard. All three of these cultivars have a larger seed size than other runner cultivars. The University of Georgia’s calcium recommendation for peanut, 500 pounds of calcium per acre in the top three inches of soil, is based on Florunner – a “medium” seed size runner-type cultivar. Georgia Green is a small-seeded runner cultivar. Dr. Glen Harris and I had seven experiments in 2009 addressing the calcium requirement in large-seeded runner cultivars. We will be sharing data from those research trials during winter county agent training sessions and grower meetings. It will be imperative that producers monitor soil pH and calcium levels in fields where these three cultivars will be grown in 2010.

Disease pressure was generally light this past year, but there were some individual fields with pod rot problems. Although pod rot can be caused by a number of soil-borne fungi, it is primarily Rhizoctonia and Pythium in most parts of Texas. Taking note of which field(s) had serious pod rot problems this year can help you manage these diseases when that field(s) is rotated back to peanut. Evaluating how effective your current fungicide program was and where, when and what might have been done differently will be important also. Finally, make sure that you know which of these two diseases you are dealing with in a particular field so that a management strategy can be developed based on the disease and how prevalent it was in that field. In many cases, individual disease management programs work better than a standard program for all fields.

Each year, we learn something about pest management and production systems. With 2009 almost behind us, there is not a better time to make notes as a reminder going into 2010. What performed best on your farm and what was unsuccessful? Record both to provide a good resource for 2010 and beyond. Good examples of what to record include: weed resistance issues; effectiveness of fungicide spray programs; was the major disease problem at the end of the season CBR, Sclerotinia blight or tomato spotted wilt; was there more-than-normal insect feeding on pods at the pod blaster? Making note [on paper] of these issues while it is still fresh in your mind can pay dividends when you begin developing and refining strategies for the following season.
Hopefully, the outlook for peanuts will be better in 2010 than we experienced in 2009, and, with improved opportunities, there may be some expansion in acreage.
We are typically finishing up harvest this time of year, but with the rain delays, harvest is still in full swing. At the writing of this article, a few acres of the newer varieties have been harvested and show promise with yield and grade. The early grades from Georgia-06G have been in the upper 70s, which is what producers have been needing from a new variety. Even though this variety has a large seed, the thin hull pays off for the producer by enabling him to get a small premium. The thin hull also gives the producer more lenience at digging if he has several acres to harvest or if the weather is threatening. Hopefully, the high grades in the beginning are not an indication of us starting too late.
