One of the first decisions cotton growers make each season is selection of which varieties they will plant. This decision has become more complex due to the availability of varieties with different pest management traits. Consequently, analyzing new varieties and technologies for their fit in each field has increased in importance. The goal for cotton growers still remains the same, selection of a cotton product that can add the most to the bottom line through adaptation, yield, and input costs.
New insect or weed management trait offerings can be alluring to growers. It is wise to evaluate any new variety or trait technology combination on a limited scale during its first year of release, unless the technological advance is so beneficial that it is worth the risk of planting a high percentage of the farm to the technology.1 It is important to remember that with any new variety or trait package, specific management may be different than with previous products, whether they are related or not.
When possible, it is best to choose a cotton variety with proven high yield potential within the specific geography. It is also important to consider the stability and quality characteristics of a cotton variety. Multiple cotton varieties with different maturities should be selected so cotton will not all mature at the same time. Staggered planting may be used when the same cotton variety is selected for multiple fields.
The decision to use a trait package should be based on several variables that are fairly common in most crop production systems. Variables include:
Table 1 provides a worksheet to help determine which cotton agronomic traits are the best fit for a grower’s operation. Importance can be ranked in the left-hand column with 1- very important, 2 - important, and 3 - unimportant.
