Fiber Quality results for the 2017 NC On-Farm Cotton Variety Evaluation Program are now in. 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 2017. Parameters include lint percentage, micronaire, fiber length, fiber strength, length uniformity, color grade, and leaf grade.
In this table, varieties are ranked in descending order according to lint percentage. During the 2017 season, essentially all of the varieties evaluated resulted in excellent fiber quality, however there were clear differences in fiber quality among these varieties across environments. It is important to note that the environment and season can greatly influence fiber quality, more-so than genetics in some years, therefore growers should understand that varieties with tendencies for poor quality in some parameters, may not necessarily result in poor quality, and vice versa.
Variety decisions are largely made based on yield potential and stability, however it is important to evaluate a variety’s fiber characteristics to avoid discounts for low quality when possible, and perhaps secure a premium for high lint quality. The good news for 2017 is that quality was high for all of the varieties in the program, which is the result of both genetics and environmental influences.
Yield and fiber quality results from the NCSU OVT program will be available very soon, so please stay tuned for those results!! We strongly encourage growers to closely observe data from both the on-farm program and OVT when making cotton variety decisions.
As mentioned in the previous articles, 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 the NC Cotton Producers Association, NCDA&CS, NC State University, Cotton Incorporated, and Seed Companies for their efforts and support of this program for the benefit of all NC cotton growers, as well the diligence and hard work that our county agents, consultants, and cooperating growers put into this program during 2017. This program was a huge success again in 2017 due to the efforts of all involved and we look forward to another year of this program in 2018!!
