Abstract: The New Brunswick Soil and Crop Improvement Association with funding from the Strategic Partnership Development Program in co-operation with the New Brunswick Department of Agriculture, Fisheries and Aquaculture conducted a soybean herbicide tolerant variety evaluation trial and a soybean variety evaluation trial in Hartland, New Brunswick in 2004. The purpose of these Maritime trials is to evaluate registered soybean varieties for their adaptability to Maritime growing conditions. In response to the increasing trend towards the growing of herbicide tolerant varieties of soybeans, trials testing both herbicide and non-herbicide tolerant varieties were conducted at four sites in the Maritimes. The varieties tested were chosen based on heat unit requirements to best fit the Maritime growing conditions. The Soybean Variety Evaluation Trial, consisting of 6 varieties, and the Soybean Herbicide Tolerant Variety Evaluation Trial, consisting of 10 varieties, were planted on the 17th day of May, 2004 with a Wintersteigar Oyjord Plot Seeder in Hartland, New Brunswick. Plots were harvested with a Hege 140 plot combine on October 14th, 2004. Dry matter yields (kg/ha) from the soybean variety evaluation trial ranged from 1802 to 2257. Lowest and highest yielding varieties were S00-AC and ADV Heartbeat, respectively. Dry matter yields (kg/ha) from the soybean herbicide tolerant variety evaluation trial ranged from 1868 to 2306. Lowest and highest yielding varieties were 25-03R and 2601R, respectively.
