    Snow on fields

    The Canola Watch 2013 exam is posted and ready. Certified Crop Advisors (CCAs) and Certified Crop Science Consultants (CCSCs) who achieve 70% will get 6.5 credits.

    Ultimate Canola Challenge results show that many of the additive products tested would not have provided an economic return — based on 2013 results. The challenge will likely be repeated in 2014, which will give us more confidence in the results.

    Growers still making seed decisions are reminded to look at www.canolaperformancetrials.ca. And if you’re in an area known to have clubroot or near an area known to have clubroot, seriously consider a clubroot resistant variety.

  • Top 10 things to do this month

    Notes

    1. Paperwork. Go through notes you took through the 2013 growing season and get them organized for next year. Look for patterns in 2013 yield maps. For example, can good areas and poor areas be explained and provide some specific management direction for 2014?

    2. Consider how to work check strips into your farm for 2014. These are a good way to check the efficacy and economic return for fungicides, second herbicide applications and other treatments.

  • Seed decisions: How to identify good data

    CPT 2013 booklet cover

    Meaningful seed comparisons usually have the following features:

    1. It comes from at least 15-20 sites, ideally from more than one year.
    2. Statistical analysis is performed on the data to test its reliability. This analysis will also identify real statistically-supported differences between treatments or varieties.
    3. Trials should follow a protocol applied across all sites. Without a protocol, differences might be due to factors other than those tested.
    4. Trials are run by a third party (an independent source). Ideally, results should be published in a peer-reviewed journal.

    The Canola Council of Canada’s Canola Performance Trials were established to provide variety data based on these principles. The tool at www.canolaperformancetrials.ca has small and large plot data from across the Prairies, and for years 2011, 2012 and 2013.

  • Buy enough seed to meet population targets

    Canola stems

    The ideal canola stand will have 7-10 plants per square foot. Canola needs a minimum of 4-5 plants per square foot, on average, to reach its yield potential. A few extra plants improves the chance of hitting yield targets, and allows for some plant loss to insects and disease. Canola with plant populations below 4-5 per square foot can still yield fairly well under good growing conditions and with good pest management, but it will not likely reach its yield potential.

    The seeding tool used to put in the crop does not change this fact.

  • Who should use clubroot-resistant canola?

    These varieties were seeded into a field known to have higher levels of clubroot. The variety on the left is resistant, the variety on the right is not.

    Clubroot resistance is an important part of clubroot management, and growers are advised to start using clubroot-resistant varieties as soon as clubroot is identified in their area. This will help keep clubroot at low levels in fields, and reduce the risk of selecting for resistant clubroot races.

  • Ultimate Canola Challenge results

    The Canola Council of Canada ran the Ultimate Canola Challenge (UCC) across the Prairies in 2013. UCC plots in Alberta and Saskatchewan compared either 6 or 13 treatments, with nine sites producing useable results. Four sites had the 6-treatment trial and 5 sites had the full 13 treatments. The following three broad statements can be made based on 2013 results:

    —Spending money in 2013 on a lot of additive products was not worthwhile.
    —Following best management practices provided best results in 2013.
    —Look carefully at the data for additive products you may be considering.
