In addition to yield, fiber quality is an important component to the value and marketability of cotton in our state and should be considered when selecting varieties. The table in the link below illustrates the average fiber quality values for each variety across all on-farm trials in 2023. Parameters include lint percentage, micronaire (MIC), fiber length (LEN), fiber strength (STR), length uniformity (UI), color grade, leaf grade, and trash.
Varieties in the tables above are sorted according to Lint percentage (gin turnout). As you can see, fiber quality for nearly all varieties in this program were good to excellent, on average. Not surprisingly though, given the especially hot and dry weather during August that limited the development of a sizeable top crop, there were a few cases of high micronaire. The frequency of high micronaire varied among the varieties within our trials. There may be a minor variety influence on these quality parameters, however, the incidences of high mic were much more noticeable in a lower yielding dryland trials that encountered severe and prolonged drought stress, suggesting a stronger environmental influence as the primary reason. In the large majority of trials, several varieties resulted in fiber quality that was well within the acceptable ranges, which is something to be celebrated.
Again, results from the on-farm program along with OVT will be discussed in much greater detail during the upcoming winter meetings, so be sure to attend one near you. Also, we want to again reiterate our appreciation to all of our leadership organizations (NC Cotton Producers Association, NCDA&CS, NC State, Cotton Inc.) and Seed Companies for their efforts and support in this program for the benefit of all North Carolina cotton growers, as well the diligence and hard work that our county agents, consultants, and cooperating growers put into this program during 2023. This program was a success again in 2023 due to the efforts of all involved and we look forward to another year of this program in 2024!
