Collapse ▲February 7th, 2017-
After a lot of positive feedback, From the Field-Agronomy Notes are back for 2017. Like last year, we hope to provide timely posts that relate to current issues faced by North Carolina tobacco producers. Be sure to check back with us on a weekly basis for all the latest news!
For some producers variety selection is just a dot in the rear view mirror at this point; however, it is likely that some are still on the fence. For those that find themselves combing through OVT data, you might consider taking a look at the some of the tables embedded in this post. In brief, we’ve taken a rather large set of data and attempted to condense it into something a little easier to digest. Table 1 presents information that was shared at each GAP meeting this winter–varieties with above average value based on the three year OVT averages. As was mentioned at each GAP meeting, this table has the quick hitting, down and dirty information needed to make an informed variety selection.

The second item to consider is new varieties. As a disclaimer, we prefer that tobacco producers try new varieties on a limited basis to ensure that those varieties mesh with their management styles. The preliminary data from 2017 releases look very good so far, so proceed with a cautious but open mind! Table 2 contains the specifics for the three varieties that will be released. Both PVH varieties will be offered by Rickard Seed Company, while NC 938 will be offered by Cross Creek Seed, Gold Leaf Seed, and Rickard Seed.

So, that’s a [brief] overview of flue-cured varieties and some of the options for 2017. Remember that as selections are made factors such as disease pressure, yield potential, leaf quality, total acreage, and curing capacity need to be considered. As tobacco farms become larger, it stands to reason that having 100% of the acreage planted to a single variety will no longer become common practice, specifically as growers strive to produce the specific styles of leaf desired by different buying entities.
