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.
Cereal Grain Cultivar Performance Under No-Till Continuous Cropping in Central Montana Off-Station Trials in central Montana off-station trials (4W2755) (2009)
(Central Agricultural Research Center, 2009) Bates, S.R.; Berg, Jim E.; Blake, Tom; Bruckner, Phil L.; Lanning, Susan P.; Talbert, Luther E.; Wichman, David M.
This report evaluates the performance of winter wheat, spring wheat, and barley varieties in no-till continuous crop systems across central Montana and to provide unbiased information on improved cereal cultivars for producers to use in the selection of best suited cereal grain varieties for the various cropping environment. The management strategy utilized for the off-station trial sites is for CARC staff to establish, monitor, harvest, record and process the data. The concept is to evaluate the cultivars under the conditions in which the producers are going to be raising them. The 2009 crop year experienced harsh, dry, cold and windy, weather during the winter and spring causing stand survival problems and inhibited the growth of both winter and spring cereals. Numerous central Montana winter wheat fields experienced winter wheat mortality in the field headlands due to tractor and implement turning. The resilience exhibited by winter wheat, spring wheat and barley in the 2009 central Montana variety trials clearly demonstrate why cereals are the predominant annual crops in central Montana. In spite of the harsh spring growing conditions all three crops produced well. barley is a crop of last resort used to deal with a particular pest, wheat disease, situation. No-till practices have proven ineffective in reducing soil erosion through increased ground cover. However, the turning area in the headlands are proving to some times and conditions to be a challenge, particularly with winter wheat, for stand establishment and survival.
Evaluation of Agronomic Performance of Winter Wheat, Spring Wheat, and Barley Cultivars in Recrop Near Moccasin, Denton, and Geraldine, Montana (2010)
(Central Agricultural Research Center, 2010) Bates, S.R.; Berg, Jim E.; Blake, Tom; Bruckner, Phil L.; Dahlhausen, S.J.; Lanning, Susan P.; Talbert, Luther E.; Wichman, David M.; Vavrovsky, Joe
This report evaluates the performance of winter and spring cereal grain varieties in continuous crop and re-crop environments near Moccasin, Denton, and Geraldine. The 2010 central Montana continuous crop cereal grain yields were generally above average do to more plentiful precipitation distributed more evenly across the growing season. In some cases, winter wheat and spring crop yields were limited by weather caused by delays in seeding date. Late seeded winter wheat experienced early and mid-spring stand losses due to weak seedlings being exposed driving winds and some soil movement around the plant crowns. Sawfly was not as great of a factor in the winter wheat, except for some late seeded stands. While sawfly was a significant factor in spring wheat, the cutting generally was not as great as that experienced in 2009. Sawfly was less of a factor in the 2010 barley crop, also. 2010 was a somewhat stressful year, for the crop producer, due to the multitude of atypical weather events that occurred across the crop year starting with extreme cold and wet conditions in October 2009. While not all cereal crops were successful, those crops that had good stands generally produced good to outstanding yields. Sawfly cutting was sufficient to provide a good evaluation of spring wheat varieties and late seeded winter wheat varieties for tolerance, yet were not so severe as to wipe out any chance for useable yield data.
Evaluation of Spring Barley Cultivar Performance Under Continuous-Crop and Crop-Crop-Fallow Systems in Central Montana (2011)
(Central Agricultural Research Center, 2011) Bates, S.R.; Blake, Tom; Dahlhausen, S.J.; Deanon, B.J.S.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the performance of spring barley cultivars in central Montana. The 2011 growing season conditions were atypical beginning with above average precipitation in September and November. Winter precipitation was near average, while April through mid-June precipitation was much above average. Mid-June through August precipitation was below average. The Moccasin location was seeded in mid-April while the Denton was seeded in mid-May due to the wet spring weather. Ability to access the site quickly and using a double disk drill made if feasible to seed the Moccasin site much earlier than most spring seedings in the area. Leaf diseases were not an issue in spite of the wet May and early June weather due to the generally dry sunny conditions in mid-June through August. 2011 did not provide conditions for good evaluation spring crop performance potential. The late seeding coupled with abundant initial moisture followed by drought conditions led to shallow root placement and possibly reduced root growth. The warmer conditions at emergence may have reduced tiller numbers which resulted in improved test weight levels.
Evaluation of Spring Barley Cultivar Performance Under Continuous-Crop and Crop-Crop-Fallow Systems in Central Montana (2012)
(Central Agricultural Research Center, 2012) Bates, S.R.; Blake, Tom; Dahlhausen, S.J.; Deanon, B.J.S.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the performance of spring barley cultivars in central Montana. The 2012 growing season was warmer and dryer than the long term average. These conditions commenced in mid-late June 2011. Warm spring growing conditions were interrupted with of freezing temperatures. At CARC, it froze five consecutive nights May 24-29, with a low of 24 F. The barley leaves showed loss of vigor as a result of the frost. There was hail at CARC on June 5 which removed 20-30% of the leaf tissue. The 2012 Geraldine trial was the first in the past decade. 2012 provided good conditions for assessing the relative performance of barley lines under moisture and heat stress. Growing conditions were less than optimum throughout the crop year. These conditions contributed to good root development and excellent grain test weights.
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.
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.
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.
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.
