Making Every Manitoba Farmer Member More Productive And Sustainable.
Significant differences in fall plant stands were found at 69 per cent of trial sites. At all those sites the highest seeding rate treatment had the highest plant stand count. Comparatively, only 20 % of sites had significant spring plant stand differences. No significant grain yield differences between treatments was detected over the last two years at any site.
Note: Trials were established in the fall of the year previous.Â

The application of Envita did not significantly improve wheat yields or quality over the standard or reduced nitrogen rates in this year’s trials. Therefore, the cost of Envita was not made up by an increase in yield or quality and there was a profit loss of approximately $14/ac compared to the treatments with the same nitrogen rate.
At these trial sites, using EEF did not increase yields compared to the traditional nitrogen products. EEFs have been found to reduced nitrogen loss, especially when conditions of high nitrogen loss exist. High risk conditions include when there is excess soil moisture or when urea fertilizers are broadcasted, and subsequent rainfalls are not received.

Research from Johnston et al. (2006) determined that 25% of fields are rated low to very low in soil P and cannot supply adequate phosphorus for a corn crop. Starter P is typically applied generously as a result of this data.
This project looks at the yield benefit vs. yield draw of starter P applied on high-P testing soils
Corn has high phosphorus requirements for plant development, beginning at germination. It is a favourable practice to seed-place a portion of the phosphorus blend, resulting in vigorous seedling growth and development. The remainder of the blend can be placed in a band near the seed row, though some grain corn farmers have adopted a split application process in-crop.
Starter phosphorus increases early-season biomass and plant height when measured at V4 and V7, respectively (Rogalsky, 2016). In the same research, silking date was 2–7 days earlier in starter-P treatments than untreated checks.
Only one site showed a significant decrease in yield when no phosphorous was applied.
Starter phosphorus applications in fields with high residual-P did not provide an economical boost in grain corn yield in any sites.
