Digging into Research
Phosphorus (P) fertilization did not increase seed yield, regardless of P rate, P placement or Olsen soil test P level, except for one out of 28 site-years. High rates of seed-placed P reduced stand establishment at 5 of 28 site-years. Limited research had been conducted on...
Averaged across 4 years, tall stubble increased yields by about 13% and short stubble increased yields by about 4% compared to yields from cultivated stubble treatments. On the semi-arid Prairies, moisture is often the limiting factor in pulse crop production. While this research is 20 years...
The economic optimum seeding rate for irrigated soybeans in southern Alberta was calculated to be 58 seeds/m2 at 80% emergence, which is equivalent to 5.8 seeds/ft2 or 252,000 seeds/acre. In southern Alberta, the development of very early maturing varieties in the MG 00 and MG 000...
Moving to a high seeding rate increased DM and TDN yields and decreased CP and P concentrations in forage corn. Using a high nitrogen fertilizer rate increased yields of DM, TDN and CP, increased soluble protein concentration, and reduced P concentration. However, when net returns...
Low plant density, split nitrogen, and PGR application all showed potential to reduce lodging risk without reducing grain yield or protein concentration. Today’s high yielding spring wheat varieties bring with them the potential for lodging under high nitrogen inputs. The objectives of this study were to...
Using fungicide and a high nitrogen (N) rate most consistently increased flax yield (11% increase). The combination of high plant density, narrow row spacing, high N fertilizer, and fungicide produced the highest yield response (23% more), but not in unfavorable growing environments. The most well-rounded...
Under irrigated and high-precipitation conditions, canola yield from 12 inch narrow-row precision planted canola was 10% higher than canola seeded with a 12 inch row air drill. However, under more water-limited conditions, yield from air drill seeded canola was equal or higher than the precision...
All cultivars in spring wheat classes CWRS, CWSWS, CPSR, CWSP and CNHR had similar yields between the 2C and 8C trigger planting temperatures. However, the ultra-early planting date had improved grain yield stability and improved growing system stability. Research from 2015 to 2018 by Collier et...
A rate of no more than 9 lbs. N + 9 lbs. P2O5/ac as a starter seed-row 28-26-0 fertilizer blend was found to be the optimum rate that maximized yield in soybean and lentil. Higher rates reduced emergence and decreased the proportion of nitrogen derived...
A meta-analysis of canola yield response to plant densities found that the economic optimal canola plant stand is 6 to 7 plants per square foot assuming recent 3 year average hybrid seed cost of $11.84/lbs., and farmgate canola price of $10.22/bu, hybrid seed size of...
