Canola variety evaluations at Western Triangle Ag. Research Center
Principle Investigator: Gadi V.P. Reddy, Superintendent and Associate Professor of Entomology/Insect Ecology, Western Triangle Ag Research Center
Personnel: John H. Miller, Research Associate and Julie Prewett, Research Assistant WTARC, Conrad, MT, and Brooke Bohannon, MSU/MAES, Northwestern Ag. Research Center, Creston, MT.
Objectives: To evaluate canola varieties grown at Western Triangle Ag. Research Center.
Methods: All plots were planted on no-till chemical fallow with a 4-row drill with spacing set to one foot. Plots were trimmed, measured for length, and then harvested with a Hege 140 plot combine. Canola seed was cleaned prior to collecting data.
Results: The canola nursery was affected by the hotter than normal June and lack of precipitation. The nursery averaged 15 bu/ac (Table 1). Test weight averaged 50.8 lbs/bu with mean seed oil content being 40%. There was no lodging to report in the canola nurseries.
Overall, the crop year temperatures where close to the 29 year average at the research center with the exception of 2.5 inches less moisture than the 29 year average. March was 7 degrees warmer than the normal. Also, June was 4.6 degrees warmer when compared to the 29 year average.
Soil temperatures at the station under chemical fallow stubble stayed under 40 degrees at a depth of eight inches until mid April. May was cool and wet. Early in June we received 0.95 inches of moisture, it warmed up and remained dry for about 30 days, during that time the canola was flowering and setting pods. Overall, it was a very poor year for canola.
A similar project will be proposed for FY 2016. The continuation of canola variety trials help elucidate researchers and farmers which varieties are better suited for that particular region in Montana.
