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 Evaluation of Durum Wheat Variety Performance Under No-Till Recrop Conditions Following a Pulse Crop Near Moccasin, Montana and 2003 Evaluation of Durum Wheat Variety Performance in Recrop Systems near Denton and Fort Benton
(Central Agricultural Research Center, 2003) Lanning, Susan P.; Philips, Dave; Talbert, Luther E.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
This report evaluates the agronomic performance of durum wheat varieties in recrop or continuous crop environments in the southern triangle and central Montana. Twenty spring durum varieties were re-cropped no-till into lentil stubble. The only supplemental fertilizer was 50lbs per acre of 20-20-20-10 blend applied through the drill at seeding. Conditions were good at seeding, but plant available moisture conditions deteriorated through June and July resulting in low yields and low test weights. Drought conditions contributed to low yields and test weights and above normal grain protein levels. New varieties are steadily replacing many of the old standards as the consistent top yielders.
2003 Evaluation of Winter Wheat Variety Performance on No-Till Recrop into Undisturbed Barley Stubble Near Moccasin
(Central Agricultural Research Center, 2003) Berg, Jim E.; Bruckner, Phil L.; Philips, Dave; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
Evaluate agronomic performance of winter wheat varieties in recrop or continuous crop environments in the southern triangle and central Montana. 2003 Winter wheat variety trial re-cropped no-till after barley was established at the Central Agricultural Research Center on land in its eighth year of continuous no-till annual cropping. Center on land in its eighth year of continuous no-till annual cropping (since 1996). The current rotation is: pulse – spring wheat – canola/mustard – barley – barley – winter wheat – pulse crop. Soil moisture conditions were fair to good at seeding. conditions were fair to good at seeding (soil moisture probe depth 10-12”). However, high post seeding temperatures and winds dried the soil late into the fall. Much above average April precipitation contributed to excellent yield potential. Return of severe drought conditions in early June resulted low test weights which deflated the yield levels. The droughty weather in combination with the variable shallow soils resulted in extremely variable yield results and low confidence results. No-Till recrop weather precipitation conditions were such that early maturity was favored. The later the maturity the greater the exposure to increased heat and reduced plant available moisture. The main factor missing was winter stress. The good performance of several numbered lines indicate the potential for improved varieties in the near future.
2004 Evaluation of Winter Wheat Variety Performance on Fallow at Geraldine and Winifred
(Central Agricultural Research Center, 2004) Berg, Jim E.; Bruckner, Phil L.; Philips, Dave; Wargo, Judee; Wichman, David M.
This report evaluates the agronomic performance of winter wheat varieties in no-till recrop (continuous) crop environments near Geraldine and Winifred, Montana. The Geraldine site was abandoned due to variable stand establishment. The site was a no-till fallow site where the surface soil was strongly crusted. However, once through the crust the moist soil went to a depth greater than 48”. Sufficient moisture was received to sprout the seed, but insufficient to sustain some seed till the roots could penetrate the crusted surface and the seeding died. The farmer used an air seeder with hoe openers and had excellent stand establishment. The soil at the Winifred site was less crusted, but stand establishment and seedling growth was not as good as the farmer had around the plots. Early May spring moisture was good. However, the winter wheat crop ran out of moisture during grain fill causing the test weights to be light and erratic. The information generated is weak due to variation across the nursery.
2004 Evaluation of Winter Wheat Variety Performance on No-Till Recrop at Moccasin and Denton
(Central Agricultural Research Center, 2004) Berg, Jim E.; Bruckner, Phil L.; Vavrovsky, Joe; Wichman, David M.; Wargo, Judee; Philips, Dave
Evaluate agronomic performance of winter wheat varieties in no-till re-crop (continuous) crop environments near Moccasin and Denton, Montana. The growing conditions for the 2004 winter wheat crop were much better than most recent years. Moisture conditions were not outstanding, but cool June temperatures minimized evaporation demand during critical seed fill. However, below average precipitation in June and July resulted in below average test weights. holding capacities. The use of broadleaf legume and oilseed crops has facilitated the use of a wider array of herbicides which has help managed wild oats, downy brome and other weeds often associated with cereal only systems. MT00159 continues to have outstanding yield performance as it has done in the two previous years. Winter wheat yields were much above expectations for both the Moccasin and Denton locations given the below average precipitation levels. The protein levels indicate some nitrogen loss may have occurred at the Denton location.
Durum Variety Evaluation in Off-Station and Re-Crop Trials Near Moccasin, Denton, Fort Benton, and Winifred (2000)
(Central Agricultural Research Center, 2000) Lanning, Susan P.; Philips, Dave; Sharp, Gail L.; Talbert, Luther E.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
This report evaluates the performance of spring durum varieties in environments and cropping methods representative of the southern triangle and central Montana. Durum yields were below average at all locations except the Denton site where yields were equal to the 4-year average for that location. Test weights were below average at all sites this year with the average over all sites and all cultivars being 57.5 lbs/bu. The Uniform Statewide Durum trial planted at Moccasin consisted of 20 entries with McNeal planted as a hard red spring wheat check. The off-station trials planted at Denton, Fort Benton, and Winifred consisted of 10 entries plus McNeal as a check. Low rainfall at the Fort Benton site was very apparent in all parameters measured in the durum trials. No cultivar yielded as well as McNeal spring wheat when averaged across the four locations, however, several entries planted at Moccasin in the Statewide nursery yielded as well or higher than McNeal. Grain proteins for all cultivars were well above the 13.5% minimum standard acceptable to buyers.
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.
Evaluation of Spring Durum Variety Performance in Trials Near Moccasin, Denton, Fort Benton, and Winifred (2001)
(Central Agricultural Research Center, 2001) Lanning, Susan P.; Philips, Dave; Sharp, Gail L.; Talbert, Luther E.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
This report evaluates the performance of spring durum varieties in environments and cropping methods representative of the southern triangle and central Montana. Grain yields ranged from 24.8 to 35.8 bu/a at the two Moccasin sites with McNeal being the top yielding variety. Yields at off-station nurseries were considerably lower. YU894-75, a variety from Western Plant Breeders, was the second highest yielding variety. McNeal was grown as a hard red spring wheat check and again out-yielded durum varieties. Mountrail was higher in yield than McNeal at the Denton and Winifred sites but McNeal topped the list when averaged across all locations and in long-term averages for any one location.
Evaluation of Spring Durum Variety Performance in Trials Near Moccasin, Denton, Fort Benton, and Winifred (2002)
(Central Agricultural Research Center, 2002) Lanning, Susan P.; Philips, Dave; Sharp, Gail L.; Talbert, Luther E.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
This report evaluates the performance of spring durum varieties in environments and cropping methods representative of the southern triangle and central Montana. The 2002 statewide durum trials seeded on fallow and no-till recrop at the CARC were hailed out about 4 days prior to full ripening. The off-station trials have been reduced to a select six entries. The small durum acreage in the area does not merit a larger effort in terms of constricted cereal crops research dollars. In central Montana, for most agronomic characters, durum varieties are generally inferior to McNeal spring wheat. This statement is based on other recent experience. McNeal was not included in the data presented here.
Evaluation of Spring Wheat Variety Performance in Trials Near Moccasin, Denton, Fort Benton, and Winifred (2001)
(Central Agricultural Research Center, 2001) Lanning, Susan P.; Philips, Dave; Sharp, Gail L.; Talbert, Luther E.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
This report evaluates the performance of spring wheat varieties in environments and cropping methods representative of the southern triangle and central Montana. Yields ranged from 6.1 to 36.5 bu/a with the highest yields at the Moccasin sites. Low moisture at the Fort Benton site contributed to lower than average yields. Reeder was one of the top yielding varieties averaging 28.6 bu/a across the five locations, however differences in yield among the varieties were significant only in the Winifred and Moccasin recrop nurseries. Low precipitation levels resulted in lower than average yields at all locations tested. This was most evident at the Fort Benton site where yields were approximately one third that of the long term averages. Yields at the Winifred site were also significantly less than long term averages for that area.
Evaluation of Spring Wheat Variety Performance Near Moccasin, Denton, Fort Benton, and Winifred (2002)
(Central Agricultural Research Center, 2002) 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 spring wheat varieties in environments and cropping methods representative of the southern triangle and Central Montana. The Moccasin location was hailed out prior to harvest. Late spring moisture provided for fair spring wheat yield levels on the other two recrop sites. Though fallow for 1.5 years, the Winifred site had limited soil water available at seeding. Unusually cool conditions in April and May helped maximize the plant growth from what soil water was available. Again, high rainfall in June helped offset this limiting factor.
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.
Evaluation of Winter Wheat Variety Performance in Off-Station Trials Near Moccasin, Denton, Fort Benton, Moore, and Winifred (2002)
(Central Agricultural Research Center, 2002) Berg, Jim E.; Bruckner, Phil L.; Philips, Dave; Sharp, Gail L.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
This report evaluates agronomic performance of winter wheat varieties in environments and cropping methods representative of the southern triangle and Central Montana. Winter wheat trials on recrop were established at Moccasin, Denton, Fort Benton and Moore and on fallow at Moccasin and Winifred. Due to severe and variable soil burial in mid-April of 2002, the Winifred trial was abandoned. Three plots were harvested at this site to get an indication of yield potential. These plots produced over 40 bushels per acre, providing a positive mark for using no-till chemical fallow. 2002 winter wheat growing conditions were sufficiently varied to provide a good year for evaluating agronomic characters. Conditions were not so extreme as to diminish the value of the results. The main factor missing was winter stress. The good performance of several numbered lines indicate the potential for improved varieties in the near future.
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.
Spring Wheat Variety Evaluation in Off-Station and Re-Crop Trials Near Moccasin, Denton, Fort Benton, and Winifred (2000)
(Central Agricultural Research Center, 2000) Lanning, Susan P.; Philips, Dave; Sharp, Gail L.; Talbert, Luther E.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.
To evaluate the performance of spring wheat varieties in environments and cropping methods representative of the southern triangle and central Montana. Yields ranged from 11 to 34 bu/a with the highest yields at the Moccasin site. Low moisture at the Fort Benton site contributed to lower than average yields. Spring wheat yields were below average at all four locations and varied greatly depending on available moisture. McNeal and Scholar, both released by Montana State University, yielded well as did Reeder, a new release from North Dakota. The average yield across all locations and all cultivars was 24.8 bu/a. The above average grain protein measured at all sites was accompanied by lower than average test weights. Heading date among cultivars was fairly uniform with all entries heading within the same week.
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. Test
