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 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.Item 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.Item Museum Spring Wheat Variety Comparison Nursery (2001)(Central Agricultural Research Center, 2001) Lanning, Susan P.; Sharp, Gail L.; Talbert, Luther E.; Wichman, David M.This report demonstrates a comparison in variety development effect on spring wheat yield levels. In general more recently released varieties had higher yields. No variety use decision should be made on this data as it is un-replicated and a single year performance.Item 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.Item 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.Item Advanced Yield and Preliminary Spring Wheat Variety Performance Trials (2001)(Central Agricultural Research Center, 2001) Lanning, Susan P.; Sharp, Gail L.; Talbert, Luther E.; Vavrovsky, Joe; Wichman, David M.This report evaluates agronomic performance of new experimental lines and existing hard red spring wheat varieties in Central Montana. The Advanced Yields ranged from 34.3 to 47.5 bu/a and averaged 40.5 bu/a. Due to low precipitation, grain yields were lower than average. Test weights averaged below normal at 58 lbs/bu and proteins averaged 17.3 percent. Preliminary Yields ranged from 29.8 to 44.6 bu/a with the average yield being 35.7 bu/a. Test weights averaged 57.4 lbs/bu and grain protein averaged 18.3 percent. Broken stems were noticed in the nurseries this year and were attributed to strawbreaker, a disease of wheat caused by the fungus Pseudocercosporella herpotrichoides. Stem breakage in the Advanced Yield grain nursery was not significant and averaged less than 0.1 percent of the total plot. Stem breakage in the Preliminary Yield grain nursery ranged from 0 to 2 percent except for one experimental line where breakage was recorded at 14 percent of the total plot. High protein levels accompanied lower than average test weights in both nurseries indicative of the low level of moisture received this year.Item 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.Item Advanced Yield and Preliminary Spring Wheat Variety Performance Trials (2002)(Central Agricultural Research Center, 2002) Lanning, Susan P.; Sharp, Gail L.; Talbert, Luther E.; Vavrovsky, JoeThis report evaluates agronomic performance of new experimental lines and existing hard red spring wheat varieties in Central Montana. The advanced and preliminary yield spring wheat nurseries were hailed on July 8, August 20, and August 22, 2002 resulting in a complete loss. Plant heights and heading dates were recorded before the trials were damaged. Heading information is presented as day of the year from January 1st.Item 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.
