2001 Cereal Forage Species, Variety and Seeding Rate Studies
(Central Agricultural Research Center, 2001) Wichman, David M.; Vavrovsky, Joe; Sharp, Gail L.; Cash, S.D.; Johnson, D.; Hensleigh, Pat F.; Hybner, Roger M.; Carr, P.
This report determines the forage production potential of spring and winter cereal grain species and varieties under dryland conditions in central Montana. Determine the optimum spring cereal seeding rates for maximum forage production. Cereal forage yields were respectable considering the low precipitation levels received over the past year. Fall 2000 and early spring seeded crops on tilled soils experienced severe and multiple soil blasting and seedling burial. Therefore, the data presented here is not sufficient to make extensive inferences or comparisons amongst varieties or species.
2003 Evaluation of Barley Variety Performance in Recrop Systems Following Oilseeds Near Moccasin, Lentils Near Denton and Winter Wheat Near Fort Benton
(Central Agricultural Research Center, 2003) Blake, Tom; Hensleigh, Pat F.; Philips, Dave; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
This report evaluates the agronomic performance of spring barley varieties in recrop or continuous crop environments in the southern triangle and central Montana. Drought conditions contributed to low yields and test weights and above normal grain protein levels. Haxby and Conlin exhibited the ability produce well and to produce decent test weights in droughty conditions. Xena exhibited good yield potential in droughty conditions, also.
2003 Spring Barley Intrastate and Preliminary Performance Nurseries in Crop-Fallow Systems in Central Montana
(Central Agricultural Research Center, 2003) Blake, Tom; Hensleigh, Pat F.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the agronomic performance of advanced (2107) and early generation (3107) spring barley development lines in crop-fallow environments in central Montana. Drought conditions contributed to low yields and test weights and above normal grain protein levels. Haxby and Conlin exhibited the ability produce well and to produce decent test weights in droughty conditions. Xena exhibited good yield potential in droughty conditions, also.
2003 Spring Oat Variety Grain Yield Evaluations
(Central Agricultural Research Center, 2003) Blake, Tom; Hensleigh, Pat F.; Vavrovsky, Joe; Wichman, David M.
Evaluate the agronomic performance of oat varieties and development lines in crop-fallow environment in central Montana. Cool wet growing conditions in April delayed emergence and development of spring seeded cereals. Dry conditions along with much above average temperatures in June and July contributed to low yield potentials and low test weights. For some cereals tillering was reduced so test weights were not as low as in other instances. Drought conditions contributed to low yields and test weights and above normal grain protein levels.
2004 Comparing the Post Harvest Dormancy of Haxby and Eslick Barley to Harrington and Other Lines
(Central Agricultural Research Center, 2004) Armstrong, Harold R.; Hensleigh, Pat F.; Wichman, David M.
This experiment was to determine if Haxby and Eslick barley have a tendency toward slower post harvest germination than does Harrington barley. Post harvest dormancy is a primary factor affecting the chance a seed will lay dormant through the fall and winter and volunteer in the crop grown the next growing season. After very minor testing, Metcalfe appears to have little post harvest dormancy and may be similar to the check Harrington. Eslick appears to have a fair amount of post harvest dormancy.
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.
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.
Evaluation of Spring Barley Variety Performance in Trials Near Moccasin, Denton, and Fort Benton (2001)
(Central Agricultural Research Center, 2001) Blake, Tom; Hensleigh, Pat F.; Philips, Dave; Sharp, Gail L.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
To evaluate the performance of spring barley varieties in environments and cropping methods representative of the southern triangle and central Montana. Yields ranged from 47.3 to 59.7 bu/a at Moccasin and from 16.1 to 21.9 bu/a at Fort Benton. Yields at Fort Benton were well below average due to low rainfall. Dry spring conditions contributed to uneven germination at the Denton site and the nursery was abandoned. The yield of Xena was high at both locations harvested although differences in yield between varieties were not significant at either site. Stressful growing conditions contributed to the increased variability. The trial at Moccasin was planted re-crop after canola and the trial at Fort Benton followed winter wheat. Barley yields ranged from average to well below average depending on the location and the amount of rainfall received. Post harvest seed dormancy evaluations were conducted on barley seed harvested from the trials as a means of predicting weed potential from volunteer barley in cropping systems. Cultivars having the longest germination times are hypothesized to be problematic as this seed would remain dormant through the winter and germinate in early spring to present a weed problem. In September, seed from seven varieties and three locations was placed on wet blotter paper and incubated at 50° F. At three, four, five, and seven days, the percentage of germinated seed was recorded. Differences in germination between the three sites were generally insignificant.
Evaluation of Spring Barley Variety Performance in Trials Near Moccasin, Denton, and Fort Benton (Moore) (2002)
(Central Agricultural Research Center, 2002) Hensleigh, Pat F.; Mickelson, Suzanne; Sharp, Gail L.; Philips, Dave; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
This report evaluates the agronomic performance of spring barley varieties in recrop environments in the southern triangle and central Montana.Barley variety trials were established on recrop near Moccasin, Denton, and Moore. The Moore site was substituted for the Fort Benton site because of the severe drought conditions that were present at Fort Benton when the spring wheat was seeded there. Unfortunately, the Moore site experienced severe drought conditions throughout the spring and early summer. Harsh drought and grasshoppers severely diminished the quality of the Moore site. The Moccasin and Denton locations provided an indication of the potential of barley varieties under marginal plant available water.
Intrastate and Early Yield Barley Variety Performance Trials (2001)
(Central Agricultural Research Center, 2001) Blake, Tom; Hensleigh, Pat F.; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the agronomic performance of new experimental lines and existing barley varieties in Central Montana. Yields in the Intrastate Trial ranged from 48.2 to 82.3 bu/a with the average yield equal to 69.8 bu/a. Grain yields in the Early Yield Trial ranged from 47.6 to 79.8 bu/a with the average yield being 68.5 bu/a. Blowing sand cut leaves off of the emerging barley seedlings but May and June precipitation promoted vigorous growth. Good grain yields and high grain proteins were obtained but test weights and percentage of plump kernels were low.
Intrastate, Early Yield, and Malt Barley Variety Performance (2002)
(Central Agricultural Research Center, 2002) Hensleigh, Pat F.; Mickelson, Suzanne; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.
This report evaluates agronomic performance of new experimental lines and existing barley varieties in central Montana. The Intrastate barley yield trial was harvested when much of the grain had 15% or higher moisture. Yields ranged from 56.4 bu/a for MT950186 down to 35.6 bu/a for Haybet. Mean protein content was 14.5 %. The early yield trial was harvested on August 12 when the grain was well ripe. Yield range was tighter for the early yield trial than the yield range found in the intrastate nursery. A few of the test lines had test weights greater than 50 lbs/bu while five had test weights of 47.6 lbs/bu or less.
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.
Selection and Evaluation of Winter Triticale Lines for Grain Production in Montana (2003)
(Central Agricultural Research Center, 2003) Bruckner, Phil L.; Hensleigh, Pat F.; Kolding, Matt; Vavrovsky, Joe; Wichman, David M.
This report evaluates winter triticale lines for adaptation to Montana conditions and to develop varieties to be release by the Montana Agricultural Experiment Station for Montana grain producers. Mild winters have prevented the critical evaluation of winter triticale lines for winter hardiness. As a result, we have been reluctant to make conclusive decisions on the fitness of winter triticale lines. to self fertile and less susceptible to out crossing. Grain yields are much improved over the years. The grain plumpness and seedling vigor of winter triticale seems much improved over lines evaluated 20 years ago.
Spring Barley Variety Evaluation in Off-Station and Re-Crop Trials Near Moccasin, Denton, and Fort Benton (2000)
(Central Agricultural Research Center, 2000) Blake, Tom; Hensleigh, Pat F.; Philips, Dave; Sharp, Gail L.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
This report evaluates the performance of spring barley varieties in environments and cropping methods representative of the southern triangle and central Montana. Yields ranged from 47 to 60 bu/a at the Moccasin and Denton sites. Yield – Yields ranged from 47 to 60 bu/a at the Moccasin and Denton sites. Yields at Fort Benton were well below average due to low rainfall and ranged from 13 to 37 bu/a. The trial at Denton was planted re-crop after lentils and the trial at Fort Benton followed barley. Barley yields ranged from average to well below average depending on the location and the amount of rainfall received. Post harvest seed dormancy evaluations were conducted on barley seed harvested from the trials as a means of predicting weed potential from volunteer barley in cropping systems. Cultivars having the longest germination times are hypothesized to be problematic as this seed would remain dormant through the winter and germinate in early spring to present a weed problem. Quick germination of a cultivar would be beneficial in that volunteer seed would germinate early in the fall and be killed by the first frost. three days. Dormancy tests for the crop year 2001 will be conducted closer to actual harvest dates to better assess differences in dormancy among cultivars.
Statewide Spring Oat Variety Performance Trial (2001)
(Central Agricultural Research Center, 2001) Hensleigh, Pat F.; Blake, Tom; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the agronomic performance of new experimental lines and existing oat varieties in Central Montana. Yields were generally just below or above the long-term averages. Moisture received in May and June promoted good plant growth and good filling of heads. Test weights were average to above average.
Statewide Spring Oat Variety Performance Trial (2002)
(Central Agricultural Research Center, 2002) Hensleigh, Pat F.; Mickelson, Suzanne; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the agronomic performance of new experimental lines and existing oat varieties in central Montana. The oat grain nursery was sprayed twice for insects, once for cutworms in May and once for grasshoppers in July. The alleys surrounding the cereal forage were sprayed with Sevin for grasshopper control. The oat for grain was harvested on the damp side due to hail risk concerns. Oat yields were down due to moisture stress, grasshopper defoliation and wind shatter. Several new lines had good to excellent performance in 2002.
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.
