2014 Wheat, Barley and Oat Variety Performance in Minnesota - Preliminary Report

Transcription

1 04 Wheat, Barley and Oat Variety Performance in Minnesota - Preliminary Report The 04 growing season was in many ways a carbon copy of the 03 season. Overall, the spring wheat pleasantly surprised most while the winter wheat, oats, and barley were a bit of a disappointment for some. While the barley crop was especially impacted by excess moisture earlier in the season, winter wheat and oats were severely affected by Fusarium head blight and crown rust, respectively. After a brutally cold winter 04 started much the same as 03 with a cold and wet April. By the end of April only 9% of the oats, and % of the spring wheat and barley acreage had been seeded. This compares to a 5-year average of roughly 40% seeded for all three crops. Cool and wet conditions continued for much of May and June. Field work started in earnest in the third week of May and by May 9th, 67% of the spring wheat, 63% of the barley, and 85% of the oat acreage had been planted; a good week behind the 03 pace and nearly 0% behind the 5-year average pace. By the third week of June nearly 60% of the State s topsoil and over half of the subsoil were rated as having a moisture surplus; a far cry from 0 and 03 drought conditions. Although the excess precipitation caused crop losses in individual fields, USDA s June yield prognosis had Minnesota s spring wheat yield predicted at 5 bushels per acre, only bushel lower than in 03 but still bushels higher than 0. Early disease problems centered around tan spot and Septoria, especially in wheat following wheat. The delayed start in combination with the cool conditions allowed for an early epidemic to develop throughout the state and producers were encouraged to stop the tan spot and Septoria epidemic with the use of a fungicide at or before the 5-leaf stage (Feekes 5). Crown rust of oats was detected by the third week of June in central Minnesota and, with many of the oat varieties being moderate to very susceptible, ultimately caused substantial yield losses across the southern half of the state. Leaf rust of wheat and stem rust of oats were detected by the second week of July, but the diseases reached economic levels in only a few fields. Damages due to Fusarium head blight were severe in winter wheat and the earliest spring wheat, especially in southern and west central Minnesota. The later seeded spring wheat crop largely escaped damages due to FHB. Nonetheless, most spring wheat that has been delivered is being tested for the presence of deoxynivalenol or DON, underscoring the nervousness of the domestic and foreign buyers alike. When harvest finally commenced producers were pleasantly surprised with the spring wheat grain yields. By August 4 th only % of the spring wheat had been harvested which compared to 60% in 03. Weather delays pushed harvest further back and fueled concerns about quality losses, in particular sprout damage. By September 5 th only 75% of the spring wheat acreage had been harvested with much of the crop in Kittson, Roseau, Marshall, and Pennington counties still standing. The USDA placed the state s final average at 55 bushels per acre in their September summary, two bushels lower than the past two years. The adverse conditions for barley were reflected in the state s average yield of 5 bushels per acre, nearly a third less than the state s average in 03. The overall quality of the spring wheat crop is, with especially the vitreous kernels count and the grain protein content, below traditional levels for hard red spring wheat. Weathering as a result of the harvest delays explain the lower vitreous kernel count and slightly lower test weights. The grain protein content varies greatly between varieties and fields. This variability can generally be traced back to not just the varietal differences but also the differences in fertility management, especially with regard to N. Spring wheat acreage remained the same at. million acres planted in 04. Barley and oat acreage continued their decline with 75,000 and 30,000 planted acres, respectively. INTRODUCTION Successful small grain production begins with selection of the best varieties for a particular farm or field. For that reason, varieties are compared in trial plots on the Minnesota Agricultural Experiment Station (MAES) sites at St. Paul, Rosemount, Waseca, Lamberton, Morris, and Crookston. In addition to the six MAES locations, trials are also planted with a number of farmer cooperators. The cooperator plots are handled so factors affecting yield and performance are as close to uniform for all entries at each location as possible. The MAES 04 Wheat, Barley, and Oat Variety Performance in Minnesota Preliminary Report 4 is presented under authority granted by the Hatch Act of 887 to the Minnesota Agricultural Experiment Station to conduct performance trials on farm crops and interpret data to the public.

2 VARIETY CLASSIFICATIONS Varieties are listed in the tables alphabetically. No other distinction or classification is used to group varieties. Seed of tested varieties can be eligible for certification, and use of certified seed is encouraged. However, certification does not imply a recommendation. Registered and certified seed is available from seed dealers or from growers listed in the Minnesota Crop Improvement Association 05 Directory, available through the Minnesota Crop Improvement Association office in St. Paul or online at INTERPRETATION OF THE DATA The presented data are the preliminary variety trial information for single (04) and multiple years (0-04) comparisons in Minnesota. The yields are reported as a percentage of the location mean, with the overall mean (bu/a) listed below. Two-year and especially one-year data are less reliable and should be interpreted with caution. In contrast, averages across multiple environments, whether they are different years and/or locations, provide a more reliable estimate of mean performance and are more predictive of what you may expect from the variety the next growing season. The least significant difference or LSD is a statistical method to determine whether the observed yield difference between any two varieties is due to true, genetic differences between the varieties or due to experimental error. If the difference in yield between two varieties equals or exceeds the LSD value, the higher yielding one was indeed superior in yield. If the difference is less, the yield difference may have been due to chance rather than genetic differences, and we are unable to differentiate the two varieties. The 5% unit indicates that, with 95% confidence, the observed difference is indeed a true difference in performance. Lowering this confidence level will allow more varieties to appear different from each other, but also increases the chances that false conclusions are drawn.

SPRING WHEAT James Anderson, Jochum Wiersma, Susan Reynolds, Roger Caspers, Matt Green, Ruth Dill-Macky, James Kolmer, Matt Rouse, and Yue Jin. Faller and Prosper combined maintained their share of nearly a third of Minnesota s spring wheat acres in 04. WB-Mayville moved up to the rd most popular variety with 8%. The next three varieties, each with between 5-7% of the acres were SY-Soren, LCS Albany, and Rollag. LCS Iguacu, Prevail, SY-Ingmar, and WB9507 were varieties released in 04 and their results have been added to the tables. Three varieties from Croplan Genetics, a new provider of HRSW genetics in the region, were also tested for the first time this year. Testing of Edge, Sabin, and Select was discontinued. The results of the state yield trials are summarized in Tables through 7. The average yield across the six southern testing locations was 75 bu/a in 04. This compares to an average of 65 bu/a in 03 and a three-year average of 65 bu/a. The seven northern locations averaged 84 bu/a in 03 compared to 89 bu/a last year and 83 bu/a for the three-year average. Tables 4, 5, and 6 present the relative grain yield of tested varieties in,, and 3-year comparisons. LCS Albany, Faller, Prosper, and HRS349 were the top yielders in the northern locations and LCS Albany topped the southern testing locations in 04. Other varieties that yielded well statewide in 04 were SY-Rowyn and LCS Iguacu. LCS Albany, Faller, and Prosper were the top yielders in the 3-year comparisons. Higher yielding cultivars tend to be lower in grain protein as is the case with these three varieties. In cooler, more-productive growing seasons, this may mean that grain protein percentage ends up below 4.0%. N fertility management is paramount to maximize grain yield and grain protein. The varietal characteristics are presented in Tables,, and 3. Table 3 summarizes all the disease reactions for individual varieties. Varieties that are rated 4 or better are considered the best hedge against a particular diseases. Varieties that are rated 7 or higher are likely to suffer significant economic losses under even moderate disease pressure. Table 7 provides insight of how varieties respond to the use of fungicides. In Lamberton, Morris, Crookston, and Roseau the State Variety Trials are grown in duplicate. The duplicate trial is treated with fungicides at Feekes 5, 9, and 0.5 to eliminate, to the extent possible, any fungal pathogens that potentially can Page 8

3 reduce grain yield and quality. Averaged across varieties over 3 years, the use of fungicide increased grain yield by 5 bushels per acre in the northern locations and 5 bu/a in southern locations. Individual varieties may have very different responses to fungicide, depending on their level of susceptibility to and intensity of fungal diseases. Use the information in Tables 3 and 7 to gain an understanding how individual varieties should be managed to reduce the yield losses caused by fungal pathogens such as tan spot, leaf and stripe rust, and FHB. The foliar disease rating represents the total complex of leaf diseases other than the rusts, and includes the Septoria complex and tan spot. Although varieties may differ from their response to each of those diseases, the rating does not differentiate among them. Therefore, the rating should be used as a general indication and only for varietal selection in areas where these diseases historically have been a problem or if the previous crop is wheat or barley. Tan spot was again widespread in 04 and likely caused significant yield reduction in susceptible varieties. Control of leaf diseases with fungicides may be warranted, even for those varieties with an above average rating. Leaf rust was not a problem in 04. However, growers should consider a variety s rating for leaf rust, and plan to use a fungicide if a variety is rated 5 or higher for either leaf or stem rust and disease levels warrant treatment. Bacterial Leaf Streak cannot be controlled with fungicides. Variety selection of more resistant varieties is the only recommended practice at this time if you have a history of problems with this disease. Breaker, Forefront, Prevail, LCS Breakaway, SY Ingmar, and SY-Rowyn offer the best resistance while varieties like LCS Albany, RB07, Vantage, and WB-Mayville have a rating of 6 or 7, indicating that they are the most consistently affected by the disease. Variety selection for 05 continues to be a balance between yield potential, disease responses, and grain quality. Vigilance against FHB remains paramount as economic losses can quickly add up with varieties rated 6 or higher. Glenn, Forefront, and Rollag provide the best resistance against FHB. Forefront has good adaptation to southern locations and both Forefront and Rollag are competitive varieties for the northern locations. LCS Albany, Barlow, Breaker, Faller, RB07, and SY-Soren are all varieties with a rating of 4 for FHB. Combined, this group of varieties includes some of the top yielders (LCS Albany, Faller) and varieties with higher grain protein content such as Rollag, Barlow, and Glenn. BARLEY Kevin Smith, Ruth Dill-Macky, Jochum Wiersma, Brian Steffenson, and Ed Schiefelbein The results of the state yield trials are summarized in Table 8. The average yield across the four testing locations (Morris, St. Paul, Stephen, and Roseau) was 03 bu/a in 04. This is bushels higher than the trial s average in 03. The highest yields were recorded in Roseau and the lowest yields were recorded in Stephen (Table 8 ). Rasmusson was the highest yielding variety followed by Celebration, Innovation and Pinnacle based on the 3 year state averages. Agronomic characteristics are described in Table 9. Lacey, Rasmusson, Tradition, Pinnacle, and Stellar-ND are the most lodging resistant of the group. The two-rowed varieties Pinnacle and Rawson had the plumpest grain while Celebration was thinner than the other varieties. Grain proteins for the six-rowed varieties ran from.9% (Innovation) to 3.8% (Robust). While the two-rowed varieties Pinnacle and Rawson had.0% and.7% protein, respectively. Table 0 describes the reaction of the currently grown varieties to the six major diseases in the region. Bacterial Leaf Streak (BLS) cannot be controlled by fungicides and there are only minimal differences in resistance among the current varieties. Conlon and Celebration have the best net blotch resistance while Quest and Conlon have the best FHB resistance among the varieties presented. The two-rowed varieties are a little more susceptible to spot blotch. OATS Jochum Wiersma, Roger Caspers, Ruth Dill-Macky, Matt Green The results of the Minnesota Field Crops Trials for oats are summarized in Tables through 4. The average yield across the five trial locations (Lamberton, Morris, Crookston, Stephen, and Roseau) was a 70 bu/a. This is substantially higher than 03 and can partially be explained by a difference in protocol. Many of the oat varieties are moderately to very susceptible to crown rust (a crown rust rating >4). Consequently crown rust infections will affect the measured grain yield. As the goal of the trials is to measure yield potential rather than the susceptibility to crown rust it was decided to treat all yield trials with a fungicide when the flag leaf was fully extended (Feekes 9), the optimum time to control crown rust. Table presents the relative grain yield of the tested varieties in and 3 year comparisons. Deon, the latest University of Minnesota release, was the top yielding variety across the State in both the single and three year comparisons followed by Newburg, the 0 release from North Dakota State University. Agronomic characteristics and disease reactions are presented in Table 3 and 4, respectively. Relative maturity as measured by the number of days to heading, plant height, and resistance to lodging have been converted to a -9 scale to allow for easier interpretation of the data. Differences for all three characteristics are generally compressed in the southern half of the state or when seeding continued on page 0 Page 9

4 continued from page9 is delayed and protracted in the northern half of the State or when seeding early. Presenting averages of the actual data therefore can be misleading. The disease ratings are based on inoculated screening nurseries for crown rust and smut on the University of Minnesota s St. Paul campus and for Barley yellow dwarf virus or red leaf of oats on the University of Illinois Champaign Urbana campus. Consider most oat varieties to be moderately to very susceptible to crown rust. The use of a fungicide at Feekes 9 is warranted if crown rust is present in the lower canopy at that time and the variety has a crown rust rating of 4 and higher. Expect some yield losses due to crown rust with the most susceptible cultivars even when a fungicide application is made at Feekes 9 if conditions for crown rust remain favorable during the grain fill period. Therefore selecting moderately susceptible cultivars like Deon, Esker is still prudent. Table.
