6 INTRODUCTION New Mexico 2004 Corn and Sorghum Performance Tests Performance tests for grain corn, forage corn, grain sorghum, forage sorghum and sorghum sudangrass were conducted at the Agricultural Science Centers at Artesia, Clovis, Farmington, Los Lunas and Tucumcari, New Mexico in 2004 (Figure 1). In addition, on-farm forage corn and sorghum sudangrass strip trials were conducted at several locations throughout the state. This report contains only information from the Agricultural Science Center tests. The New Mexico corn and sorghum performance testing program is part of an ongoing program to provide farmers, Extension workers and seed industry personnel with reliable, unbiased, information that will allow a valid comparison of corn and sorghum varieties/hybrids at various locations throughout the state. The state of New Mexico encompasses eight climate zones, all of which have some form of agricultural production (Figure 2). Variability in climate, soils, water and local production practices contribute to the need for crop performance tests throughout the state. Climate data for the Agricultural Science Center testing locations are shown in Table 1. Growers who use this report to make cropping decisions should rely primarily on results from tests near their location or in comparable climate zones. Figure 1. Corn and sorghum testing locations.

8 TEST LOCATIONS The New Mexico corn and sorghum performance testing program is supported by paid fees from the cooperating companies. Personnel at each location determine which tests will be conducted at their site and seed companies are invited to participate in those tests. Because seed company participation in individual tests and locations is voluntary, many of the hybrids/varieties that are grown in the state are not included in the tests, and different groups of hybrids/varieties are evaluated at the different locations. A list of seed companies that participated in the 2004 fee-test program and relevant contact information are presented in Appendix A. Additional company names and contacts may be added to the list of prospective companies by contacting the Agricultural Science Center at Clovis, 2346 State Road 288, Clovis, NM 88101, (505) , clovis@nmsu.edu. Entry forms for the 2005 corn and sorghum performance tests were mailed to seed companies in January Additional 2005 entry forms can be obtained from the address above. TEST PROCEDURES In an effort to provide readers with easily accessible information, procedural data for individual tests are presented in the Test Description tables that immediately precede the summary of results for the tests. The Test Description tables contain information on location, test design, management practices and growing conditions. Test description tables are designated with an A suffix. All of the Agricultural Science Center performance tests were replicated randomized complete block (RCB) designs. Where appropriate, statistical analyses were used to calculate measures of least significant difference (LSD), coefficient of variability (CV) and F test values. All LSD s are reported at the 95 probability level. For the LSD value to be considered significant, the F test value in that same column must be less than. If the F test value is greater than the LSD is non-significant at the 95 probability level. When the F test value is less than, it is appropriate to use the LSD value as a measure of the magnitude by which one entry must differ from another to be considered significantly different. The CV is a measure of variability relative to the mean. A CV below 10 generally indicates reliable, uniform data. CV s of 10 to 20 are indicators of normal variability for grain and forage tests. Yields for the grain tests (corn and sorghum) are presented on a bushel-per-acre or pound-per-acre basis, adjusted to a standard moisture content and bushel weight. Corn yields are calculated at a standard moisture of 15.5 and a bushel weight of 56 lb. Standard moisture content and bushel weight for grain sorghum is 14 and 56 lb, respectively. Dry and green forage yields are reported for the forage tests, in tons per acre. Moisture at harvest was calculated from a representative sample (approximately 1 lb) from harvested plots. Samples from variety tests at the Agricultural Science Centers at Artesia, Clovis, Los Lunas and Tucumcari were dried in a forced air oven (150 o F) for determination of moisture content. Moisture content determinations at Farmington were derived from air-dried samples. Sub-samples of the dried material from tests at Artesia, Clovis and Los Lunas were submitted to the University of Wisconsin, Soil and Forage 3

9 Analysis Laboratory, Marshfield, WI for nutrient composition analysis using near infrared reflectance spectrophotometry (NIRS). For these trials, milk production estimates were calculated using the University of Wisconsin Milk2000 spreadsheet program. Subsamples of dried forage at the Agricultural Science Center at Farmington were sent to Ward Laboratories, Kearney, NE for nutrient composition analysis by NIRS procedures. RESULTS Results for the 2004 corn and sorghum hybrid/variety tests are shown in Tables Results are presented on tables designated with B or C suffixes. Within tables, hybrids and varieties are ranked according to grain yield or total dry forage yield. A glossary of terms used in the tables is presented in Appendix B. Grain Corn Entries for grain corn tests were accepted by the Agricultural Science Centers at Clovis, Farmington and Los Lunas. The Clovis grain corn test contained 11 entries. Mean grain yield was 247 bu/ac and significant yield differences were observed (Table 2A-B). Two grain corn tests were conducted at Farmington. The early season grain corn test contained 13 entries. Mean grain yield was 202 bu/ac and yields were different. (Table 3A-B). Farmington s full-season grain corn test consisted of 12 entries. Mean grain yield was 173 bu/ac and yield differences among hybrids were not significant (Table 4A-B). The grain corn test at Los Lunas contained three hybrids, which produced a mean grain yield of 169 bu/ac (Table 5A-B). There were no yield differences for grain corn entries at Los Lunas. Forage Corn Forage corn tests were conducted at the Agricultural Science Centers at Artesia, Clovis, Farmington and Los Lunas. The Artesia forage corn test consisted of 23 entries. Mean dry forage yield was 9.25 ton/ac and yield and forage quality differences were observed (Table 6A-B). There were 30 entries in the Clovis forage corn test. Mean dry forage yield was ton/ac (Table 7A-B). Hybrids differed in nutrient composition and yield. Sixteen hybrids were evaluated in the Farmington forage corn test. Dry forage yield averaged 8.78 ton/ac and yields were similar for all hybrids (Table 8A-C). Differences were observed for most measures of nutrient composition. The Los Lunas forage corn test was comprised of 11 hybrids. Mean dry forage yield was 8.06 ton/ac and dry forage yields were similar for all hybrids (Table 9A-B), however differences among nutrient parameters existed. Grain Sorghum Entries for grain sorghum fee-tests were accepted at the Agricultural Science Centers at Clovis, Los Lunas and Tucumcari. At Clovis, grain sorghum tests were established 4

10 under full irrigation, limited irrigation and dryland. Tests at Los Lunas and Tucumcari were conducted under irrigated and dryland conditions, respectively. The full irrigation grain sorghum test at Clovis consisted of eight entries. Mean grain yield was 7,602 lb/ac and differences among varieties were observed (Table 10A-B). There were 11 entries in the Clovis limited irrigation grain sorghum test which produced a mean grain yield of 5,974 lb/ac with significant differences (Table 11A-B). The dryland grain sorghum test at Clovis consisted of nine entries. Planting was delayed until July 2 due to dry conditions in early spring, followed by several days of wet weather. Grain yields were affected negatively by the late planting and below normal heat unit accumulations. Mean grain yield was only 592 lb/ac, but differences were observed (Table 12A-B) The irrigated grain sorghum test at Los Lunas contained seven entries. Mean grain yield was 9,184 lb/ac and yields were similar for all entries (Table 13A-B). The dryland grain sorghum trial at Tucumcari consisted of seven entries. Drought conditions during heading and pollination, accompanied by poor stand emergence, resulted in non-measurable grain yields (Table 14A). Uniform areas within each plot were harvested to determine forage yield. Those data are not presented in this report. Forage Sorghum Entries for forage sorghum evaluations were accepted at the Agricultural Science Centers at Artesia, Clovis and Los Lunas. Clovis tests were conducted under irrigated and dryland conditions. There were 12 entries in the forage sorghum test at Artesia. Mean dry forage yield was 7.75 ton/ac (Table 15A-B). Forage yields were similar for all entries. At Clovis, there were 17 entries in the irrigated forage sorghum test. Mean dry forage yield was 7.42 ton/ac and differences were observed for yield and nutritive parameters (Table 16A-B). The dryland forage sorghum test at Clovis contained five entries. Mean dry forage yield was 1.72 ton/ac and differences existed for all reported variables (Table 17A-B). Late planting and a lack of moisture in the soil profile contributed to low yields, even though precipitation was above average in the latter part of the growing season. Los Lunas had seven entries in its forage sorghum test. Mean dry forage yield was 7.92 ton/ac (Table 18A-B). All entries produced similar dry forage yields, but differences existed for green forage yield and most nutritive components. Sorghum Sudangrass Entries for sorghum sudangrass tests were accepted by the Agricultural Science Centers at Artesia, Clovis and Los Lunas. Clovis conducted separate irrigated and dryland tests. There were seven entries in the sorghum sudangrass test at Artesia. Plots were harvested on August 10 and October 26 and mean season-total dry forage yield was 7.22 ton/ac (Table 19A-C). Forage yield differences were observed for the first harvest and for season-total dry forage yield. All hybrids produced similar yields at the second harvest. 5

11 The irrigated sorghum sudangrass test at Clovis contained 11entries. Harvests were conducted on July 28 and October 21. Mean dry forage yields from the first and second harvests were 4.85 and 3.82 ton/ac, respectively (Table 20A-C). Season-total harvest data were not calculated, because data were collected from unequal numbers of replications, due to harvester problems at the second harvest. Differences were observed for some measures of nutritive quality. Four hybrids were entered in the dryland sorghum sudangrass test at Clovis. The test was harvested only once, on September 15. Mean dry forage yield was 1.98 ton/ac and yield differences were observed (Table 21A-B). The Los Lunas sorghum sudangrass test contained four entries that were harvested once, on September 10. Mean dry forage yield was 8.09 ton/ac and dry forage yields were similar for all entries (Table 22A-B), but differences were observed for all other measured parameters. Forage Sorghum and Sorghum Sudangrass A combined dryland forage sorghum-sorghum sudangrass test, containing 12 entries, was established at the Agricultural Science Center at Tucumcari. The test was planted on May 20, but emergence did not occur until measurable precipitation was received in late-june (Table 23A). This lack of precipitation and winds in early July caused desiccation and stand loss. The test was not harvested. 6
