2016 On-Farm Cotton Variety Trial Results

Transcription

1 COTTON AGRONOMY 2016 On-Farm Cotton Variety Trial Results Variety selection is one of the most important decisions in cotton production. Increasing genetic yield potential and rapid cycle breeding allow seed companies to bring an ever-increasing number of top performing varieties to market each year. Although the yield benefits from selecting the right variety can be great, selecting the wrong variety for a particular environment can cause a loss in profit potential. Variety performance is heavily dependent on environment. Environmental conditions not only change with geography, but also from season to season on a given farm. It is important for growers to make variety selections based on multi-year, multi-location data and not make a decision based on a single farm or year. Yield stability over multiple environments helps to ensure performance through varying geographic and climate conditions. Each farm has its unique challenges and benefits, and no single variety is the best for all situations. It is important for producers to know what their yield limiting factors are and choose an appropriate variety for their circumstances. Diversifying varieties across a growers acreage is also an important strategy. The On-Farm Cotton Variety Testing program, conducted by personnel in Alabama Cooperative Extension and Auburn University, conducts large scale strip variety trials at various on-farm locations throughout Alabama. The farm locations are selected based on representative cotton acreage in the state, and the trial entries are the top performing varieties for Alabama. The 2016 On-Farm Variety trials were hugely successful this year and reflected the tremendous yields seen across Alabama. The trials depend heavily on our farmer cooperators for success and without their dedication, this information would not be possible. We also thank the Alabama Cotton Commission and Cotton Incorporated for their generous financial support, as well as the companies whose entries are represented in the trials for the donation of seed. The results are presented in the following series of tables. As a caution, our samples are ginned on a small, 10 saw table top gin so will give higher Turn-Out numbers than what will be found at a commercial gin. This leads to higher absolute yield figures. The numbers presented are meant for a relative comparison between varieties. The complete analysis of these tables will be discussed in more detail at the winter meetings, so please contact your Regional Extension Agent or visit alabamacrops.com to find a meeting near you.
