While this Saskatchewan study did show a yield response for foliar-applied phosphorus (P) when compared to a control without any P fertilizer, the best practice is still to meet crop needs with fertilizer applications before or at the time of seeding. This study evaluated the response...
In canola, the net return with the full rate of nitrogen side-banded at seeding was always greater than the same rate split-applied as side-banded N and fertigation. In HRSW spring wheat, late-season in-crop applications of N by fertigation could be used to boost grain protein,...
When stripe rust severity was low, resistant and intermediate wheat and barley varieties did not suffer significant yield losses. When leaf spot and stripe rust disease levels were high, a foliar fungicide application was necessary to reduce yield losses even on resistant varieties. Seven spring wheat...
Existing combine grain loss monitors could not be correlated to an actual grain loss measurement. However they did provide an indication if grain loss was increasing or decreasing with different feed rates. You can’t manage what you can’t measure. That adage from the business world also...
Inter-row seeding field pea into 8 to 12 inch (20 to 30 cm) tall wheat stubble significantly improved standability between 6 to 23% when lodging occurred, and would be a low cost method of improving pea harvestability. The three plant growth regulators compared were of...
In a 3-year crop rotation, replacing summerfallow with a pulse crop increased total grain production by 35.5%, improved protein yield by 51%, and enhanced fertilizer-N use efficiency by 33%. A 3-year crop sequence study was repeated five times (five cycles) from 2005 to 2011 at Swift...
Seed solid-stemmed CWRS and CNHR wheat varieties at 30 to 35 seeds per square foot to maximize stem solidness and reduce the impact of wheat stem sawfly. For hollow-stemmed CWRS varieties and durum wheat, seed at 40 to 45 seeds per square foot. Growing solid-stemmed wheat...
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...
Averaged over 6 years from 2010 to 2015, growing canola in rotation with other crops produced 19.4% (9.4 bu/ac) higher yield over continuous canola. Wheat yields were 4.7 bu/ac (7.2%) higher than continuous wheat. When a rotation included pea once every three years, a saving...
Diverse crop rotations had similar net returns to canola-wheat rotations one-half the time and up to $45 per acre more the rest of the time. Adding integrated weed management practices without relying on wild oat herbicides resulted in similar wild oat pressure as canola-wheat rotations....
