Starter nitrogen (N) up to 75 lbs. N/ac broadcast and incorporated before planting a Maturity Group 00 soybean cultivar found no differences in biomass, grain protein, or oil content. There was no yield response for treatments receiving starter N fertilizer relative to the unfertilized control...
[Editorial Note: This 26-site research study was conducted across the Prairies 20 years ago, but results and lessons learned are still applicable today.] In-crop application of 14 lbs. N/ac of broadcast ammonium nitrate or foliar-applied UAN were generally equally effective at increasing grain protein content in...
Niger grain yield increased linearly by 18% with increasing nitrogen rates. Seeding depths down to one inch (2.5 cm) allowed placement of seed into soil moisture to support emergence and optimize yield. Niger is an open-pollinated oilseed crop, and was domesticated in Ethiopia. While niger is...
Research was conducted in southern Alberta to look at the effects of long term feedlot manure application on irrigated barley yield, macronutrient supply, earthworm abundance, and water extractable carbon in a clay loam soil. Two to 3 years after manure application was stopped, barley silage...
This one-year study supports previous recommendations that in-soil banding of nitrogen fertilizers during seeding or near to the time of seeding is a best management practice to enhance nitrogen use efficiency (NUE). Increasing farm size in western Canada has led many farmers to move back to...
Generally, a black medic cover crop reduced the proportion of small aggregates and increased the proportion of large aggregates. Medic offers a natural way to maintain soil health in low external input cropping systems. Black medic is a self-regenerating cover crop that grows under the crop...
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...
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...
