Split applications of N usually provided the maximum yield and protein, particularly with Agrotain or SuperU. This study consisted of two experiments each conducted at five sites across western Canada at Brandon, Manitoba, Hallonquist (south of Swift Current), Saskatchewan, and Lethbridge and Lacombe, Alberta to assess...
Seed-placed rates of up to 35 lbs. P2O5 per acre (40 kg P2O5/ha) were safe across a wide range of conditions. However, seedrow safety was hard to predict, so sideband is still the preferred method for high P application rates. When soil test P levels...
On land without a history of soybeans, dual inoculant provided a 24% yield benefit with an overall yield increase of 7 bu./acre (500 kg/ha). Starter N provided little yield benefit when good N-fixation was achieved. In-season N application could be used to rescue a poorly...
Wheat yield was up to 45% higher after two years of alfalfa and up to 60% higher after two years of red clover compared to barley-flax rotations. The yield advantage carried over into the second year with up to 55% higher canola yield after the...
At Swift Current, Saskatchewan, faba beans fixed 60 pounds of nitrogen (N) per acre followed by field pea at almost 50 lbs., chickpea at 46 lbs., lentil at 44 lbs., and dry bean lagging behind at 8.3 lbs. But there were varietal differences within each...
Soybeans provide similar rotational benefits as pea and lentil on subsequent wheat and canola crops – but keep an eye on phosphorus fertility. Nutrient uptake, removal and rotational benefits have been frequently studied for pea and lentil in western Canada. Research at the University of Saskatchewan...
Maintain canola and malt barley yield and quality with 25% less nitrogen (N) fertilizer with pulses in rotation. A three year study at seven locations in western Canada looked at the impact of crop rotation and nitrogen rate on canola and malt barley yield and quality...
