Many producers are in the process of booking seed for next year. There are several new varieties in new technologies that are worthy of a look.
Variety selection is perhaps the most important decision a producer makes. Once planted, no amount of worry, work, or money can make up for a poor decision. Our recommendations for planting is that roughly two-thirds of your acres be planted with varieties that are proven on your farm. Of the remaining acres, limit new varieties to no more than 10% of your total acreage. The remaining 25% should be dedicated to those varieties in which you have limited experience. This strategy provides stability while allowing for evaluation of new varieties.
There are a number of unbiased information sources available to assist in selecting new varieties. Our primary source is the University Variety Testing Program. Results from the Arkansas Trials conducted by Dr. Fred Bourland may be found at http://arkansasvarietytesting.com/home/cotton/ soon.
A great deal of information is collected and presented in a way to help evaluate fiber quality, maturity, growth characteristics, and other variety traits as well as yield. County data included in this blog will also be included in the University Variety Testing Program publication.
A total of 11 locations were tested and are summarized in a couple of different ways.
The first table of the linked pdf shows the 7 locations where multiple technologies were evaluated. The top portion contains the varieties that were common to all locations.
We had 4 locations that only B2XF varieties were planted. As many producers are focused on that technology, we decided to summarize performance of just the B2XF varieties across all 11 locations in the second table below. The top portion contains varieties common to all locations.
The attached file contains seedcotton, lint fraction, and other details for each location. Fiber quality data and statistical analysis in the works.
Don’t restrict yourself to your home state or area. In Arkansas, it is appropriate to evaluate variety performance trials from neighboring states in the Mid-South. Evaluating the consistency of a variety under a wide array of conditions will be beneficial.
Contact your local county Extension agent for assistance in obtaining or interpreting variety performance data and to get the date and location of upcoming county production meetings.
