Evaluation of Spring Cereal Grain Yield to Over-Seeding on Soil Injected with Tractor Exhaust (2010)
(Central Agricultural Research Center, 2010) Dahlhausen, S.J.; Wichman, David M.
This report evaluates whether if injecting diesel tractor exhaust in to the soil, along with wheat seed would enhance grain yield. This trial was set up on both winter wheat and spring wheat. A farm scale exhaust injection system was used to establish wheat adjacent passes in fields of winter wheat and spring wheat. The first seeding pass was done without injecting the exhaust. The idea was to not have any fresh exhaust residues in the system when seeding the untreated check pass. The second pass was made with the exhaust injector system in operation. No start up fertilizer was placed with the seed. The moisture from the exhaust causes the granular fertilizer pearls to gum and build up on the opener. Therefore no starter fertilizer (NPK or S) was placed with the seed. Liquid N was applied sequential applications of 4 gallons per acre of 28-0-0 (11.2 lbs N)and 5 gallons of 24-0-0-0 ( 12.0 lbs N). This initial evaluation of injecting diesel exhaust into the soil along side the seed did not result in any positive results.
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.
Off-Station Winter Wheat Cultivar Performance on Fallow in Central Montana (2010)
(Central Agricultural Research Center, 2010) Berg, Jim E.; Bruckner, Phil L.; Dahlhausen, S.J.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the relative performance of winter wheat cultivars and development lines in central Montana crop environments. The 2010 growing season conditions were generally optimal for wheat production. However, fall seeding conditions were challenging if the seeding was not accomplished prior to early October. For many locations, a combination of events led to early to mid-November seeding of winter wheat. Late seeding coupled with late April cold driving winds caused some marginal winter wheat stands. Generally, plentiful growing season precipitation helped off-set some of the stand deficiencies. Winter wheat continues to produce much higher yields than spring wheat at the Geraldine location. There is not a spring wheat trial established at Winifred due to 1990 trials which showed large yield differences between the spring wheat and winter wheat. Thus, the choice was made to discontinue spring wheat trials at Winifred. Winter wheat will continue to be the crop of choice in these areas.
Off-Station Spring Wheat Performance Under Fallow in Central Montana (2010)
(Central Agricultural Research Center, 2010) Dahlhausen, S.J.; Talbert, Luther E.; Lanning, Susan P.; Vavrovsky, Joe
This report evaluates the performance of spring wheat cultivars in fallow near Geraldine. To fit the cooperators change in systems, the trial was established as no-till recrop after winter wheat in a crop-crop-fallow system. The 2010 growing season conditions were generally optimal for spring wheat production. Cooler July weather contributed to good spring wheat yields. While the Geraldine site has typically been fallow in the past it is now in a winter wheat – spring wheat – fallow system. The Geraldine environment provides a good evaluation of both yield potential and sawfly tolerance. Vida, a semi-hollow stem line, has been a consistently high yielder at Geraldine for the past few years along with solid stem lines in Choteau, Corbin, and O'Neal and a low sawfly attraction variety Conan. Vida is intermediate in test weight and protein content. The higher protein content varieties generally are lower yielding and that has been the case at Geraldine with AP604CL and Kelby.
Evaluation of Winter Wheat Cultivar Performance Under Continuous Crop, Crop-Crop-Fallow and Crop-Fallow Systems in Central Montana (2011)
(Central Agricultural Research Center, 2011) Berg, Jim E.; Bruckner, Phil L.; Dahlhausen, S.J.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the relative performance of winter wheat cultivars and development lines in central Montana crop environments. 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 Winifred location was hailed out in mid July. Stripe rust infestations were wide spread in winter wheat.
Evaluation Commonly Grown Barley, Spring Wheat and Winter Wheat Cultivars for Post Harvest Seed Dormancy
(Central Agricultural Research Center, 2012) Wichman, David M.; Deanon, Benri J.S.; Dahlhausen, S.J.
This report Identifies those barley and wheat cultivars with higher or lower levels of post harvest seed dormancy. Knowledge of the relative post harvest dormancy of barley and wheat cultivars can be instrumental in variety selection by growers and by grain buyers. The 2012 post harvest dormancy assessments were conducted on barley, winter wheat next, and spring wheat last. The species sequence is the order in which post harvest dormancy breaks down.
Evaluation of Spring Wheat Cultivar Performance Under Continuous-Crop and Crop-Crop-Fallow Systems in Central Montana (2011)
(Central Agricultural Research Center, 2011) Dahlhausen, S.J.; Lanning, Susan P.; Talbert, Luther E.; Vavrovsky, Joe; Wichman, David M.
This report evaluates the relative performance spring wheat cultivars and development lines in central Montana crop environments. 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. The Denton and Geraldine locations were seeded in mid-May due to the wet spring weather. The combination of short lentil stubble and ability to access the site quickly made if feasible to seed the Moccasin much earlier than most spring seedings in the area. Stripe rust infestations were wide spread in winter wheat but were not a problem in much of the spring wheat due to the generally dry sunny conditions in mid-June through August. The 2011 results re-emphasize the importance of getting spring wheat seeded prior to mid-spring. Yields were severely reduced by the mid- May seeding date. Vida continues to be an outstanding yield standard in central Montana. However, it does have lower protein than most of the spring wheat entries.
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 Wheat Cultivar Performance Under Continuous-Crop and Crop-Crop-Fallow Systems in Central Montana (2012)
(Central Agricultural Research Center, 2012) Wichman, David M.; Talbert, Luther E.; Lanning, Susan P.; Deanon, B.J.S.; Vavrovsky, Joe; Dahlhausen, S.J.
This report evaluates the relative performance of spring wheat cultivars and development lines in central Montana crop environments. Twenty spring wheat entries were established on NTCC at Moccasin, Denton, Geraldine, and Ft. Benton. The 2012 growing season was warmer and dryer than the long term average. Geraldine had more optimal precipitation. Warm spring growing conditions were interrupted with of freezing temperatures. At CARC, it froze five consecutive nights May 24-29. The spring wheat showed less frost stress than barley. Hail on June 5 removed 10-15% of the spring wheat leaf tissue. Sawfly cutting was minimal to none. The 2012 spring wheat crop ripened 10-15d earlier than normal. Ft. Benton trial is the first there in ten years. 2012 was a drought year. However, the 2012 yields were not as far off the six year average as might have been expected.
