Item Evaluation of Fall Seeded Winter Pea and Lentil Line Performance (2004)(Central Agricultural Research Center, 2004) Wichman, David M.; Chen, Chengci; McPhee, K.; Muehlbauer, F.J.; Neill, Karnes E.; Short, R.W.; Vavrovsky, JoeThis paper evaluates winter hardiness of fall seeded winter dry pea and lentil lines. All winter pea lines exhibited good winter hardiness, with the trial having an average of 106% survivability (Table 3). No differences were observed among the winter pea lines. The winter lentil lines did not exhibit good winter survival as the trial averaged only 69.8% survival (Table 4). Line LC9978094 had the highest survival rating (88.5%), but was not significantly higher than lines LC9979120, WA8649041 and LC9978057.Item Evaluation of Fall Seeded Winter Pea and Lentil Line Performance (2005)(Central Agricultural Research Center, 2005) Wichman, David M.; Chen, Chengci; McPhee, K.; Muehlbauer, F.J.; Neill, Karnes E.; Short, R.W.; Vavrovsky, JoeThis paper evaluates winter hardiness of fall seeded winter dry pea and lentil lines. All winter pea lines exhibited good winter hardiness, having a spring stand of 7.1 plants ft-2 or 95% of the target seeding rate (7.4 plants ft-2; Table 3). No differences were observed among the winter pea lines. The winter lentil lines exhibit slightly poorer winter survival than the winter pea lines. The trial had an average spring stand of 9.8 plants ft-2 or 89% of the target seeding rate (11.1 plants ft-2; Table 4).Item Evaluation of Fall Seeded Winter Pea and Lentil Line Performance (Western Regional Winter Dry Pea and Lentil Evaluation Trials) (2007)(Central Agricultural Research Center, 2007) Wichman, David M.; Chen, Chengci; Neill, Karnes E.; McPhee, K.; Short, R.W.; Vavrovsky, JoeThis paper evaluates winter hardiness of fall seeded winter dry pea and lentil lines. A difference in spring stand (visual evaluation) amongst the winter pea lines was exhibited, with Granger Austrian winter pea having the best stand, but was significantly similar to five other lines (Table 3). Upon visual observations, large differences in winter survival among the winter lentil lines were observed (Table 4). Turkish-type (“T”) lines LC02600449T and LC03600295T had the poorest spring stands with an average score of 1.6 and 1.8 (out of possible of 5), respectively.Item Evaluation of Fall Seeded Winter Pea and Lentil Line Performance (Western Regional Winter Dry Pea and Lentil Evaluation Trials) (2008)(Central Agricultural Research Center, 2008) Wichman, David M.; Chen, Chengci; Neill, Karnes E.; McPhee, K.; Short, R.W.; Vavrovsky, JoeThis paper evaluates winter hardiness of fall seeded winter dry pea and lentil lines. A difference in spring stand (visual evaluation) amongst the winter pea lines was exhibited, with Granger Austrian winter pea having the best stand, but was significantly similar to five other lines (Table 3). Upon visual observations, large differences in winter survival among the winter lentil lines were observed (Table 4). Turkish-type (“T”) lines LC02600449T and LC03600295T had the poorest spring stands with an average score of 1.6 and 1.8 (out of possible of 5), respectively.Item Statewide Evaluation of Chickpea (Garbonzo Bean) Variety Performance (Montana Uniform Chickpea Performance Trial)(Central Agricultural Research Center, 2001) Wichman, David M.; Neill, Karnes E.; Eckhoff, Joyce L.; Holmes, Jeffrey A.; Jackson, G.; Kephart, Ken D.; Lamb, Peggy F.; Miller, James B.; Miller, Perry R.; Muehlbauer, F.J.; Short, R.W.This report evaluates grain yield potential of chickpea varieties under dryland conditions across Montana. Drought-like conditions persisted into the 2001 cropping year across much of Montana. Below normal growing season precipitation was recorded at all sites, with Sidney being the exception. The above normal precipitation that fell during June, followed by warm humid conditions, at the Sidney site accelerated an outbreak of Ascochyta blight causing severe damage to the chickpea trial. Low grain yields were reported at the Conrad site which received only 2.28 inches of precipitation between seeding date and end of July. By summarizing four years (1998-2001) of performance trials, statewide, Dwelley (kabuli-type) chickpea was out yielded by all other varieties of chickpeas evaluated, except for the one-year trial at Bozeman (Table 23).Item Statewide Evaluation of Chickpea (Garbonzo Bean) Variety Performance (Montana Uniform Chickpea Performance Trial) (2002)(Central Agricultural Research Center, 2002) Wichman, David M.; Neill, Karnes E.; Eckhoff, Joyce L.; Holmes, Jeffrey A.; Jackson, G.; Kephart, Ken D.; Lamb, Peggy F.; Miller, James B.; Miller, Perry R.; Muehlbauer, F.J.; Short, R.W.This report evaluates grain yield potential of chickpea varieties under dryland conditions across Montana (Moccasin Testing Site Only). Drought-like conditions persisted into the 2002 cropping year across much of Montana. Below normal growing season precipitation was recorded at all sites at Moccasin, which received only 86% of its normal growing season precipitation from May 1 through July 31. An outbreak of Ascochyta blight was detected on July 15th, and an application of Quadris was applied to suppress the disease until the plots could be harvested. A severe thunderstorm accompanied by hail, hit the site on August 20th, causing at least 50% losses in yield (Table 13). Desi and small kabuli chickpea grain yields, since 1998, have averaged 1,300 pounds per acre under dryland conditions at Moccasin (Table 15). By analysis (which extrapolates yields over missing years), CDC Desiray has been the best grain producer, averaging 1,422 pounds of grain per acre (23.7 bu/acre). However, it has not significantly out produced any of the other desi-/small kabuli-type chickpeas. The large kabuli chickpeas have averaged only 363 pounds per acre (includes the hail damaged yields of 2002). It is unclear at this time what is causing the low kabuli-yields reported at Moccasin. Further research is needed. CDC Xena, had the best 4-year grain average, producing 437 pound per acre.Item Statewide/Western Regional Evaluation of Chickpea (Garbonzo Bean) Variety Performance (2003)(Central Agricultural Research Center, 2003) Wichman, David M.; Chen, Chengci; Holmes, Jeffrey A.; Miller, Perry R.; Muehlbauer, F.J.; Neill, Karnes E.; Short, R.W.; Vavrovsky, JoeThis paper evaluates grain yield potential of chickpea varieties under dryland conditions across Montana. Despite well above average moisture in April, drought-like conditions returned in June and July. Grasshopper damage, which consisted of cutting of peduncles and the loss of pods (fell to the ground) resulted in significant grain yield losses in the late maturing kabuli-type chickpeas.Item Western Regional Dry Pea and Lentil Trials (2003)(Central Agricultural Research Center, 2003) Wichman, David M.; Chen, Chengci; McPhee, K.; Muehlbauer, F.J.; Neill, Karnes E.; Short, R.W.; Vavrovsky, JoeThis paper evaluates dry pea and lentil lines for grain production potential in Central Montana's dryland environment. Despite receiving more than three-times the monthly average precipitation in April, crop year (April through August) precipitation was 85 percent of normal (8.73 inches vs. 10.24 inches), as severe drought like conditions continued in Central Montana. A severe infestation of grasshoppers plagued Central Ag. Research Center (CARC). These factors, coupled with the late seeding date (May 7th), resulted in much below normal pulse grain yields.Item Western Regional Dry Pea, Lentil and Chickpea Trials (2004)(Central Agricultural Research Center, 2004) Wichman, David M.; Chen, Chengci; McPhee, K.; Muehlbauer, F.J.; Neill, Karnes E.; Short, R.W.; Vavrovsky, JoeThis paper evaluates dry pea, lentil and chickpea lines for grain production potential in dryland environments. Despite receiving 74% of the normal crop-year precipitation (April-August), pulse crop yields were higher than in recent years. This rise in yields is attributed to early seeding (April 7th), being seeded into fallow soil conditions, timely precipitation events and cool summer temperatures.Item Western Regional Dry Pea, Lentil and Chickpea Trials (2005)(Central Agricultural Research Center, 2005) Wichman, David M.; Chen, Chengci; McPhee, K.; Muehlbauer, F.J.; Neill, Karnes E.; Short, R.W.; Vavrovsky, JoeThis paper evaluates dry pea, lentil and chickpea lines for grain production potential in dryland environments. Due to wet conditions in late April, the trials were seeded later (May 3rd) than desirable. As a result, yields were significantly depressed. Grain yields are reported as both harvest moisture and 12% moisture equivalent.Item Western Regional Dry Pea, Lentil and Chickpea Trials (2007)(Central Agricultural Research Center, 2007) Wichman, David M.; Chen, Chengci; McPhee, K.; Muehlbauer, F.J.; Neill, Karnes E.; Short, R.W.; Vavrovsky, JoeThis paper evaluates dry pea, lentil and chickpea lines for grain production potential in dryland environments. Dry pea grain yields averaged 1,422 lbs of dry pea production per acre (Table 3). Delta smooth yellow pea had the highest grain production (1,627 lbs acre-1) but was not significantly higher than eight other pea lines (based on LSD(0.05)). Lentil yields were suppressed and may have been due to a growing nematode problem in adjacent fields (not confirmed in field trial established). The trial averaged 955.1 lbs per acre (Table 4). The “Brewer”-type lentil, Merrit, produced the most seed, averaging 1128.0 lbs acre-1, but was not statistically higher (based on LSD0.05) than eight other lines. Chickpea grain yields averaged 758.5 lbs of grain production per acre (Table 5.). Dylan kabuli-type chickpea produced the most grain (978.8 lbs acre-1), but was significantly similar to line CA0090B347C (based on LSD0.05).
