3 2009 Gulf Coast Corn Performance Trials Rudy Alaniz, Technician Clinton Livingston, Technician Texas Agrilife Research and Extension Center Corpus Christi, Texas Variety selection is the most important decision made during the year. Unlike herbicide or insecticide decisions that can be changed during the season to address specific conditions and pests, variety selection is made only once and that selection will dictate the management of that entire field for the entire season. Select corn hybrids on proven performance records, not solely on the recommendation of your local seed dealer. A hybrid with demonstrated superior yielding ability across multiple locations and/or years is likely the one that will perform consistently on your farm. To assist producers with variety selection, trials are conducted annually in counties located throughout the Gulf Coast region. Testing hybrids across many locations and/or years exposes them to a diversity of growing environments such as may occur on your farm over many years. We believe this approach provides a good foundation of information that can be utilized to begin the decision making process for the upcoming season. If possible, do not rely on results from a single location in a single year. There is no guarantee that conditions will be similar in future years or at other locations. Unfortunately, the rate of hybrid turnover on the market and in performance tests has accelerated in recent years, reducing the availability of multi-year test results. This rapid turnover underscores the need for annual examination of hybrid performance at several locations. Each year review as many public and private tests within your region as possible before making a decision. In 2009, nine trials were conducted throughout the region. Trials were located in Fort Bend, Brazoria, Matagorda, Wharton, Colorado, Jackson, Victoria, Dewitt, and Hidalgo counties. All three regions were given a core set of varieties (pages 4-6) to maintain some uniformity, however, at the discretion of the producer some locations added varieties from companies that did not choose to participate at the beginning of the season. Also included in this report is the hybrid rankings based on bushel yield across all locations for the Upper Gulf Coast region (page 8). Trials were replicated in a randomized complete block design which enables the data to be analyzed statistically which gives one greater confidence in knowing if there are truly any statistically differences in hybrids. The statistical analysis at the bottom of the table presents a general overview of the uniformity of the test conditions (soil type, cultural practices, insect damage, etc.). Trial locations with large LSD s (more than 10 bushels/acre) generally offer little useful information due to non-uniform conditions (higher degree of variability). 1
4 The cv indicates the degree of precision with which the varieties are compared and is a good index of the reliability of the trial. It expresses the experimental error as a percentage of the mean; thus, the higher the cv value, the lower is the reliability of the trial. A cv value of 10 or less for yield is considered excellent or very reliable data. s that are statistically different from one another will not have the same letter next to the corresponding number value in a column. Conversely, hybrids that are not statistically different from one another will have the same letter next to the corresponding number value in the column. Means separation were performed at the 0.05 level of probability as determined by fishers protected LSD. Statistical analyses were performed in ARM. Table 1 list the participating county, Extension agent, and the producer who planted the trial. Tables 2-4 list the participating seed companies and hybrid entered by county and region. Table 5 includes agronomic information on each county hybrid trial location. 2
