Results Analysis

This study was correctly set up from seeding all the way through harvest but there are no solid conclusions that can be made from the experiment.

In Rep 2 of the study it appears there are not the same patterns in yield as what was seen in Rep 1. It is hard to understand why this occurred but perhaps there was something going on in the soil or environment that may have affected the results.

Throughout the season treatment 3 looked the worst and it was clear at harvest as seen with the yields above. We also noticed the wild oats pressure was increased in the treatment 3 throughout the season. There also appeared to be more wild oats in the treatments containing the 70-20-0-0 fertility versus the 95-45-20-10 fertility. This may be the result of higher fertility treatment being able to produce a healthier more competitive crop when weed pressure is present.

The higher moisture this year created environments favourable for in season flushes of wild oats in which group 2 herbicides may not have been able to control. Unfortunately, this wild oat pressure may have affected the results of the trial and may have altered the yields in the study.

The treatments containing the Accolade from Verdesian both appeared better than the check when the plants were dug and roots observed on July 7th as seen in the pictures above. The root mass appeared more aggressive on the Accolade treatment that had the 70-50-0-0 fertility versus the 95-45-20-10 fertility treatment with Accolade. The reason for this may be the plants did not have to create as an aggressive rooting system to find adequate nutrition in season with the higher fertility blend.

The lower fertility treatments with the more aggressive rooting system may have been the result of the plant searching for more nutrients in the soil and the Accolade was able to assist the plant in doing so when the plants are under more stress. The yields between the two Accolade treatments were not as expected but this may be answered by altered seed and fertility placement that was the result of challenging seeding conditions that afternoon after a rainstorm that passed through the filed before the seeding of these treatments (6 and 7) were complete. The wet soil was sticking to the compaction wheels on the air drill and may have altered the seeding depth and placement which may explain the unusual results in yield seen in those treatments.

For some reason the seed treatment also did not display promising yield results over the untreated comparisons. The ideal seeding conditions in the spring during seeding and minimal seed stress in the field may have not allowed the seed treatment to have any affect in yield. More likely in a spring with earlier seeding into wet cold soils where there is a higher stress on seed the performance of the seed treatment would be increased.
