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,...

An optimum seeding rate between 30,000 and 35,000 seeds/ac for hybrid 63A21 sunflower, and between 40,000 and 45,000 seeds/ac for open-pollinated AC Sierra was determined under no-till cropping systems in Saskatchewan. At N fertilizer prices of around $0.50/lbs., the recommended N fertilizer rate based on...

Seeding early should increase the likelihood of harvesting quality grain before weathering, but this did not guarantee higher yields or higher test weights. Generally, 71 lbs. N/ac resulted in optimum test weights and often produced optimum economic returns. Selecting a variety with genetics for high...

The research suggests that improving pulse nitrogen fixation by targeting an increase in nodule numbers and nodule biomass could help improve long term cropping sustainability and reduce reliance on inorganic N fertilizer. In addition, developing pulse varieties with improved water-stress tolerance may improve the N-fixation...

A nitrogen fertilizer rate of 89 lbs. N/ac provided the most consistent economic returns when oat prices were between $2.50 and $3.00 per bushel. Fungicide application did not provide a benefit at any N application rate. In an effort to maximize yield and quality, some oat...

Sensitivity of pulse crops to seedrow placed nitrogen, phosphorus and sulfur fertilizer products was lentil > pea ~ chickpea > soybean ~ black bean > faba bean. Overall and under good moisture conditions, a maximum of 10 kg N/ha rate as starter in the seedrow...

On sites testing low in nitrogen (N) fertility, flax yields were 39% higher with rates of 90 lbs. N side-banded per acre. Flax response to phosphorus (P) averaged 7% and rates of no more than 18 to 36 side-banded P2O5 per acre were justified. Phosphorus...

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...
