2003 Field Performance Evaluation of Fungicides on Spring Wheat
(Central Agricultural Research Center, 2003) Carlson, G. R.; Riesselman, John (Jack); Vavrovsky, Joe; Wichman, David M.
This report evaluates the relative effect of seed treatments on spring wheat production. Drought conditions contributed to low yields and test weights and above normal grain protein levels. These trials continue to show how spring wheat varieties perform in less than ideal plant available water conditions.
2004 Intra-State Winter Wheat Variety Performance
(Central Agricultural Research Center, 2004) Berg, Jim E.; Bruckner, Phil L.; Carlson, G. R.; Eckhoff, Joyce L.; Grey, William E.; Johnston, Robert H.; Kushnak, Gregory D.; Kephart, Ken D.
This report evaluates new and existing winter wheat lines and varieties in dryland under various growing conditions in Montana and Western North Dakota. The 2004 Intrastate Winter Wheat Evaluation nursery was grown at Bozeman, Havre, Huntley, Kalispell, Moccasin, and Sidney, Montana and Williston, North Dakota. The 2004 Montana winter wheat crop varied widely across research locations due to extremes in winter survival, precipitation and growing season temperatures. The eastern portion of Montana had harsh winter conditions that caused pockets of winter kill. Severe drought conditions persisted in eastern Montana south of highway 200. Northwest Montana and north central conditions were much improved over the 2003 crop year. Cool June weather compensated for below average precipitation in central Montana. Dry conditions during grain fill reduced test weights at all locations except Bozeman. Harvest weather, in general, was good. The environmental conditions across the intra-state winter wheat locations provided for an ideal range of yields for good assessment of yield potential. These conditions provided an excellent range of yields and test weights. Grain protein levels were high. Conditions were suitable for good winter survival evaluations at Sidney and Williston.
2008 Statewide Spring Dry Pea and Lentil Variety Evaluations
(Central Agricultural Research Center, 2008) Chen, Chengci; Neill, Karnes E.; Carlson, G. R.; Miller, John H.; Stougaard, Robert N.; Strang, L.; Westcott, M.; Knox, M.; Eckhoff, Joyce L.; Miller, Perry R.; Holmes, Jeffrey A.; Tarum, M.; Koenig, V.
This paper evaluates spring dry pea and lentil varieties for grain production potential in diverse Montana environments. Dry pea grain yields were respectable among most of the testing sites (Table 3). Havre had the greatest production, with a trial average (converted to 13% moisture) of nearly 65 bushels acre-1 (65.6 bu/acre – 3,868 lbs/acre). Moccasin had the worst yield averaging less than 17 bushels acre-1 (16.1 bu/acre - 986 lbs/acre) which is much below long-term means and is thought to be due to poor sub-soil moisture, hail damage, snow and record lows in mid-June, and an insect infestation. As expected, no single entry was the top yielding variety at every location. However, the smooth yellow line PS9910140 did top the trial yields at three locations, and was among the top cultivars in the other locations. Lentil grain yields ranged from 450 to 2300 lbs acre-1 and were respectable across the state (Table 7), with the exceptions being Conrad (450 lbs acre-1), which had a poor stand establishment and Sidney (trial abandoned), which had poor soil moisture at seeding and experienced drought-like conditions through the growing season. Differences in grain yield between the dry pea and lentil trials at Moccasin can be attributed to planting of the lentil trial in a different field, which contained better stored soil moisture. The “Richlea”-type lentil line LC01602300R showed the greatest seed production at three of the six sites, with a grain yield ranging from 9.0 (at Conrad) to over 44 bushels acre-1 (Creston), but was not significant at any location (based on LSD0.05).
Montana Intrastate Winter Wheat Variety Evaluations (2009)
(Central Agricultural Research Center, 2009) Berg, Jim E.; Bruckner, Phil L.; Carlson, G. R.; Eckhoff, Joyce L.; Grey, William E.; Johnston, Jeffrey; Kushnak, Gregory D.; Kephart, Ken D.; Riveland, N. R.; Stougaard, Robert N.; Wichman, David M.
This report evaluates new and existing winter wheat cultivars and lines under various dryland growing conditions at Montana and Western North Dakota research centers. It also provides unbiased information on improved winter wheat cultivars for producers to use in the selection of cultivars best suited for their cropping environment. The 2009 Montana Intrastate Winter Wheat Nursery was established at Bozeman, Havre, Huntley, Conrad, Kalispell, Moccasin, Sidney, and Williston. The Sidney location was not harvested due to winter kill. Across locations performance means will be high-lighted in this summary. New cultivars and development lines were among the top performers for yield, test weight, protein content, and stem solidness and plant height.
