Mississippi State University Extension sincerely appreciates the time and effort of the cooperating growers and Mississippi State University agronomists. In addition, several independent consultants provided a tremendous level of assistance with these trials, including Ty Edwards, Jason Grafton, Bert Falkner, Tucker Miller, and Tim Richards. Sincere gratitude is also extended to the following seed companies and representatives for providing seed for these trials: BASF, Andy White; Crop Production Services/Dyna-Gro, Scott Cummings; Phytogen Cottonseed, Tom Eubank; Americot/NexGen, Chase Samples and Terry Campbell; and Delta and Pine Land, Greg Ferguson. Cooperation from all aforementioned parties is essential for success of the MSU Extension On-Farm Cotton Variety Demonstration Program. In addition, partial financial support for this project was provided by each participating company and Cotton Incorporated.

Introduction

The cotton variety selection process is often difficult and, in many cases, leaves growers wondering for the remainder of the growing season whether they made the right variety selection decisions. Furthermore, the rapid introduction of new varieties and discontinued production of “older” varieties has become commonplace over the past several years.

Historically, a premier variety would remain in the marketplace for a long period. However, a variety that performs well today typically has a life span of 4–6 years. One that does not perform well will likely remain on the market for less than 3 years. In addition, the historical standard for variety testing information was to have 2–3 years of data before releasing any given variety. Today, 1–2 years of “broad-scale” variety testing is common before releasing a new variety. Therefore, greater demand has been placed on testing a variety in as many environments as possible as a substitute for multiple years of data. In most cases, variety testing before release is conducted by private industry through a series of testing methods and through university official variety trial (OVT) programs. Official variety trial data is typically available for 1 year before the release of a given variety.

Our on-farm testing program is not designed to replace or compete with small-plot OVT testing programs; rather, it is designed to complement the data that is provided by OVT programs. The use of large-plot variety trial data in conjunction with small-plot OVT data provides a tremendous resource to Mississippi growers with respect to variety performance.

Methodology

The on-farm testing program at Mississippi State University is designed to test varieties in as many environments as possible. Limiting the number of entries allows for efficient planting and harvest operations and requires a minimum amount of time from cooperating growers. The number of variety entries each company is given depends on market share. In addition, one to two at-large entries are given to smaller companies in order to provide equal opportunity to as many seed providers as possible.

Our on-farm variety tests are usually planted in 8- or 12-row sets using planting equipment provided by each grower. In some cases, 4- or 6-row sets are used, depending on site characteristics and grower preference. In addition, two replications of each variety are planted and harvested at all locations. Plot lengths ranged from 500 to 2,600 feet in 2020, depending on the characteristics of the field the trial was conducted in. Seed treatments are at the discretion of the company providing seed. A premium seed treatment package including an insecticide, fungicide, and nematicide was provided for each variety. In-season management is at the discretion of growers, who are encouraged to manage the plot area as they would manage any given field on their farm.

Each replication for each variety was individually harvested using standard harvest equipment. Harvest weights were collected using a boll buggy or trailer modified to display the weight of seed cotton contained therein. Before all harvest operations, each boll buggy or trailer was calibrated by the Mississippi Department of Agriculture and Commerce to ensure that accurate harvest weights were collected. An 8- to 10-pound seed cotton sample was collected for each variety tested.

To reduce ginning time, subsamples from replications number 1 and 2 were composited into a single sample. Seed cotton was ginned at the University of Tennessee – West Tennessee Research and Education Center. Ginning equipment at the WTREC consists of a 20-saw Continental Eagle gin equipped with a stick machine, incline cleaners, two lint cleaners, and a condenser. Fiber quality for each ginned sample was determined using a high-volume instrument (HVI) located at the United States Department of Agriculture Classing Office in Memphis.

Entries

A maximum of 10 core variety entries per year are allowed in the MSU Extension On-Farm Cotton Variety Demonstration Program. Entries are allotted by market share from respective companies. One entry per year is automatically given to the variety planted on the highest acreage in the previous year based on the annual Varieties Planted Report from USDA-AMS. In 2020, Bayer/Delta and Pine Land was allotted three spots; Phytogen Cottonseed was allotted three spots; Americot was allotted two spots; and two additional “at-large” entries were given to provide parity to smaller companies with less resources than larger companies. Entries in the 2020 MSU Extension On-Farm Cotton Variety Demonstration Program are listed in Table 2.

Site Characteristics

Locations for the 2020 MSU Extension On-Farm Cotton Variety Demonstration Program are listed in Table 1. Yield trials were conducted at a total of 16 locations. Seven locations were in the Delta and nine in the Hills region. All Delta locations were irrigated, and eight of nine Hill locations were dryland. The remaining Hill location (Crawford) was pivot irrigated. Field sites were chosen based on grower preference and required elements to conduct a reliable yield trial.

Reported Data and Analysis

Each data table includes the following: variety, lint yield, lint percent, micronaire, staple length (in inches), fiber strength, fiber uniformity, and leaf grade. Data analysis using SAS v. 9.4 was conducted on all replicated trials. Grand means (averages) are presented as well as least significant differences (LSD). Least significant differences are the smallest value with which we can confidently say there is a difference between two means. Differences in means less than the given LSD value are likely due to variability within a given field or environment. For non-replicated trials and fiber data at individual locations, LSDs are not applicable. For locations that were replicated and data from one replication of a given variety was lost, SAS will interpret these data as missing and provide data analysis based on estimates. Therefore, average data for a given location may be slightly different than data reported.
