Canola School: Diagnosing stand establishment issues

[ad_1]

Doing a stand establishment evaluation won’t be probably the most glamorous a part of scouting, however it’s a extremely essential piece of knowledge to know what number of canola seeds had been put within the floor, what number of have emerged, and why.

“We know that canola seed is a premium input; it’s not a cheap thing to buy, so we need to treat it like the premium input that it is,” says Autumn Barnes agronomy specialist on the Canola Council of Canada, on this Canola Faculty episode.

As canola is rising, it’s essential to get out and scout and to determine why some vegetation won’t have emerged — typically it’s simply because not sufficient time has elapsed between seeding and scouting, typically it’s moisture, chilly soil temperatures, seeded too deep, or an excessive amount of seed-placed fertilizer are simply a number of the the reason why a canola plant didn’t emerge.

Seedling illness, particularly with the onset of cooler climate, generally is a concern, as are herbicide carryover issues, in components of the prairies which were actually dry.

“As those seedlings get bigger, past that two- to four-leaf stage, usually after your herbicide application, get out and actually start recording your plant establishment numbers,” says Barnes. The Canola Council of Canada has a brand new software out there this 12 months referred to as Canola Counts, that may map plant density and emergence throughout the Prairies.

“The tool, in one part is about collecting this data, so we can annually map emergence and density over the Prairies, but in equal part, it’s also so that we can encourage everybody to get out and count plants, and make it part of their regular routine in the spring time,” says Barnes.

Discolouration of leaves and stems, or feeding notches could be tell-tale indicators that your canola seedling is just not doing effectively. Barnes additionally says {that a} scouting hoop or sq. will get a extra practical common of harm to seedlings from pests like flea beetles or cutworms. Lastly, the Canola Council recommends a stand of 5 to seven vegetation per sq. foot, with leeway for insect pests.
