AAC Brandon wheat yields were observed under the influence of different R.A. West Int. proprietary amendments including humic acid.

As per being a demo with only one replicate, there is not enough data to bring forth a statistically proven conclusion.  Looking at the results of each respective plot, Calpak Foliar treatment yielded highest at 35 bushels per acre and exhibited the lowest test weight at 42 lb/bu. The test weights of all other treated plots ranged from 61-64 lb/bu. Protein content ranged from 10.6% to 14.5%, with Humik Blend 2 representing the former, and Humik Blend 1, the latter.

All varieties falling between SY Torach and AAC Connery produced similar yields, 11-16 bu/acre (P=0.03); Likewise, test weights were not significantly different among varieties aside from the lowest values exhibited in AAC Connery and Ellerslie (P=0.04). Ranging 13-13.2%, CS Jake, CDC Landmark, and Parata displayed the highest protein contents (P<0.0001). The yield analysis C.V. was 18.1, thus yield results can not be considered reliable.

AAC Foray VB alongside CS Accelerate produced the highest yields (P=0.01). No variety produced significantly different test weight values from another (P=0.07). In 2020, mean yield ranged from 25 to 40 bushels per acre, whereas last year’s NPARA yields spanned 50 to 80 bushels per acre. Test weight values ranged from 60-65 lbs/bushel. AAC Penhold and SY Rowyn had the highest protein content, at 12.94% and 12.70%, respectively, whereas AAC Foray VB had the lowest at 10.94% (P=0.02). Often, yield and protein content have an inverse relationship, AAC Foray displays this principle here as expected.

Number of plants per square foot was greater in the CDC SKRush variety while the lowest number of emergent plants per square foot was found in the CS Tracker variety (P≤0.0001). Percentage of moisture content was lower in the Ellerslie variety while higher moisture content was present in SY Torach (P=0.0010). As for yield, the AAC Brandon was the variety that produced the most compared to variety the CS Jake variety which produced the least yield (P=0.0231). Test weight among variables was statistically the same (P=0.0667).

Overall, it can be argued that CS Tracker and CS Jake are the lowest yielding varieties which coincides with them having the lowest number of emergent plants per square meter. SY Torach and CDC SKRush, two varieties with higher moisture content and emergence, respectively, can also be varieties as high yielding as AAC Brandon, as all these three varieties are statistically the same.

Canada Prairie Spring (CPS) Wheat

Moisture and number of plants per squared foot were the same among all varieties. Test weight and yield however, differed as heavier test weights were reported in AAC Foray VB and AAC Goodwin compared to the rest of the varieties (P=0.0161). AAC Goodwin was the highest yielding variety whereas AAC Foray, AAC Penhold and SY Rowyn were the lowest. Generally, AAC Goodwin was the top variety in terms of test weight and yield, with respect to SY Rowyn which underperformed in relation to the rest of the CPS varieties.
