Item Oat Variety Evaluation in Re-Crop Trials at Moccasin (2000)(Central Agricultural Research Center, 2000) Berg, Jim E.; Blake, Tom; Bruckner, Phil L.; Hensleigh, Pat F.; Lanning, Susan P.; Philips, Dave; Sharp, Gail L.; Talbert, Luther E.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.This report evaluates the agronomic performance of oat varieties under no-till recrop conditions at Moccasin. The 2000 no-till recrop oat trial was seeded into barley stubble. Soil moisture was fair to good for seeding in the spring. The surface soil was almost mud due to the shade and shelter provided by the standing stubble and chaff. The no-till recrop yields were slightly reduced due to the low precipitation levels during the 2000 crop year. The combination of good vegetation control and the water conservation provided with no-till provided for good yields in a dry year.Item Winter Wheat Variety Evaluation in Off-Station and Re-Crop Trials Near Moccasin, Denton, Fort Benton, Moore, and Winifred (2000)(Central Agricultural Research Center, 2000) Berg, Jim E.; Bruckner, Phil L.; Philips, Dave; Sharp, Gail L.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.This report evaluates the performance of winter wheat varieties in environments and cropping methods. Dry conditions resulted in lower than average yields at all sites with the exception of Moccasin where re-crop wheat followed barley. Growing season precipitation of 3.9 inches at the Fort Benton site contributed to low yields ranging from 8.8 to 12.6 bu/a. Yields were highest at the Moccasin site ranging from 35.8 to 46.2 bu/a. No yields were recorded at the Denton site due to a plugged opener during seeding that resulted in non-uniform plots. Grain protein was lowest at the Denton site and highest at the Fort Benton site. Although moisture for the 2000 crop season was generally higher than that received the previous year, timing of rainfall contributed to a lower than average yield at most sites. Yields at the Moccasin site met the seven-year average for cultivars grown at that site. Yields at all other sites were well below their ten-year averages as noted in multi-year yield summaries for each site. seeded into spring wheat stubble. The Moccasin trial was seeded into barley stubble. All cultivars had acceptable test weights averaging 61.2 lbs/bu across all sites and all cultivars. TestItem Evaluation of Experimental Winter Triticale Lines for Adaptation in Montana (2001)(Central Agricultural Research Center, 2001) Berg, Jim E.; Hensleigh, Pat F.; Hybner, Roger M.; Kephart, Ken D.; Kolding, Matt; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.This report documents the observations of winter triticale lines to determine if any perform well in Central Montana. Triticale plots were seeded on a west-facing slope to obtain maximum exposure to winter temperatures and wind. Plant densities and percent stand indicate no significant differences among the triticale lines in their ability to survive winter. Triticale lines did not differ significantly from Tiber winter wheat in winter hardiness or in grain yield. Grain yields averaged 2520 lbs/a and test weights were above average at 53.6 lbs/bu. Similar results were obtained in the Statewide Triticale Nursery planted in a more protected area on the research center. Triticale lines tested had a wide range of heading dates and test weight values. Early maturing lines with acceptable test weights and yields comparable to Tiber winter wheat can be selected for and continued in subsequent yield trials.Item Statewide Winter Triticale Trial (2001)(Central Agricultural Research Center, 2001) Berg, Jim E.; Hensleigh, Pat F.; Hybner, Roger M.; Kephart, Ken D.; Kolding, Matt; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.This report evaluates winter triticale selections which exhibit high yield, good quality, and winter hardiness in environments and cropping methods representative of Montana. To develop a winter feed grain adapted to livestock production areas in eastern Montana because seeding spring grains conflicts with calving and lambing. Differences in yield between cultivars were not significant at the Bozeman or Huntley sites and no single cultivar was the highest yielding at all sites. Test weights for the triticale entries ranged from 48.7 to 57.3 lbs/bu based on a standard of 50 lbs/bu. The average test weight for all entries and all locations was 54.7 lbs/bu, well below that of Tiber winter wheat but above the standard of 50 lbs/bu. Grain protein levels ranged from 14.0 to 19.1 percent and nursery averages were generally one percent lower than that of Tiber winter wheat.Item Evaluation and Selection of Superior Winter Triticale Lines for Grain Production and Winter Hardiness (2002)(Central Agricultural Research Center, 2002) Berg, Jim E.; Hensleigh, Pat F.; Hybner, Roger M.; Kephart, Ken D.; Kolding, Matt; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.This report identifies and selects winter triticale lines that exhibit superior grain yield and winter hardiness in central Montana and throughout the state. In 2002, several winter triticale lines had grain yields (pounds/acre) greater than Tiber winter wheat at Moccasin, Bozeman, and Sheridan. However, the winter triticale yields were not overwhelmingly higher than Tiber yields, as has occurred some years. Several triticale lines have proven to have grain yield potentials greater than Tiber winter wheat. Unfortunately, we have not had winters suitable for the evaluation of winter hardiness. Some of these lines would be suitable for production in areas of Montana with marginal winter stress or for seeding into undisturbed stubble.Item Northern Regional Winter Wheat Performance Nursery (2001)(Central Agricultural Research Center, 2001) Berg, Jim E.; Bruckner, Phil L.; Graybosch, Bob; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.This report evaluates winter wheat lines developed throughout the Great Plains and Pacific Northwest for adaptability, agronomic performance, yield, and quality in the Northern Plains and Central Montana. Yields ranged from 41.9 to 64.1 bu/a with the average yield equal to 50.9 bu/a. The nursery was planted on fallow. Low moisture levels resulted in lower than average yields. were below average at 59.6 lbs/bu and proteins averaged 15.3 percent.Item Intrastate, Advanced Yield, and Preliminary Winter Wheat Variety Performance Trials (2001)(Central Agricultural Research Center, 2001) Berg, Jim E.; Bruckner, Phil L.; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.This report evaluates agronomic performance of new experimental lines and existing winter wheat varieties in Central Montana. Yields from the Interstate Nursery ranged from 38.3 to 54.4 bu/a with the average equal to 47.2 bu/a. Test weights were lower than average at 57.6 lbs/bu and grain proteins averaged 15.4 percent. Yields of grain varieties grown in the Advanced Yield Winter Wheat Nursery ranged from 41.7 to 57.4 bu/a with the average being 47.2 bu/a. Test weights were below average at 59.5 lbs/bu and grain protein averaged 15.4 percent. Grain yields in the preliminary nurseries ranged from 36.7 to 59.5 bu/a. Yields averaged 47.9 bu/a in the Preliminary A nursery and test weights were below average at 57.6 lbs/bu. Grain yields in the Preliminary B nursery averaged 51.4 bu/a and test weights were average at 60.1 lbs/bu. Soil moisture at seeding time was good and urea was broadcast in early September. Winter survival rates averaged 78 to 84 percent and total annual precipitation of 10.6 inches resulted in lower than normal yields. Lower than average test weights were accompanied by higher than average grain protein levels.Item Evaluation of Winter Wheat Variety Performance in Off-Station Trials Near Moccasin, Denton, Fort Benton, Moore, and Winifred (2001)(Central Agricultural Research Center, 2001) Berg, Jim E.; Bruckner, Phil L.; Philips, Dave; Sharp, Gail L.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.This report evaluates the performance of winter wheat varieties in environments and cropping methods representative of the southern triangle and central Montana. Moisture severely limited the plant growth and development of winter grains at the Fort Benton site. Low test weights from grain grown at the Fort Benton site were accompanied by high protein values. Grain shatter from hail damage at Denton reduced the yields collected from that site. Promontory, Erhardt, Rampart, and Norstar were among those most susceptible to grain shatter. Most resistant to shatter were Judith and Morgan. Sawfly damage was very evident in Fort Benton this year. Stems had been girdled at the soil level. Most susceptible to sawfly cutting were Elkhorn, Neeley, Judith, and Rampart. While all plots sustained some cutting, the cultivar with the least amount of sawfly damage was NuPlains. Since stem counts were conducted on only the first rep, results may be inconclusive.Item Intrastate, Advanced Yield, and Preliminary Winter Wheat Variety Performance Trials (2002)(Central Agricultural Research Center, 2002) Berg, Jim E.; Bruckner, Phil L.; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.This report evaluates agronomic performance of new experimental lines and existing winter wheat varieties in Central Montana. The statewide nurseries were seeded with a double disk drill into untilled 2000 barley stubble. Much of the stubble had deteriorated, but there was sufficient stubble to influence snow catch. The 50 pounds per acre of a 20-20-20-10 blend was placed with the seed at seeding. The intrastate and advanced yield trials were harvested prior to receiving significant rain. Therefore, the grain test weight should be generally better than the preliminary nurseries. The advanced yield nursery had deer trails through one of the ranges. The winter wheat yields were much above what would normally be anticipated for the levels of spring soil moisture and spring precipitation. Cooler than average temperatures in April and May contributed to lower evaporative demand and reduced soil drying.Item Northern Regional Winter Wheat Performance Nursery (2002)(Central Agricultural Research Center, 2002) Berg, Jim E.; Bruckner, Phil L.; Graybosch, Bob; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.This report evaluates winter wheat lines developed throughout the Great Plains and Pacific Northwest for adaptability, agronomic performance, yield, and quality in the Northern Plains and Central Montana. The USDA Northern Regional Performance Winter Wheat Nursery yields were near or above average. Average yields for the entries ranged from a high of 52.3bu/a for NI98418, a hard red variety, down to 36.2 bu/a for NW99L7083. This nursery was planted on no-till chemical fallow. Due to the mild winter weather, winterkill was not a factor. However, the standing stubble surely reduced soil moisture loss to the atmosphere and enhanced yields.
