Durum and HRSW Best Management PracticesA “Real-World” Perspective
Vision Research Park—who are we
Affiliated with United Agronomy out of Berthold 5 offices in northwest North Dakota Created in 2008 Vision Research Park responsible for:
Contract research program Crop consulting/scouting Precision agriculture services
Basic agronomics
Control what we can control Genetics Plant population Plant nutrition Eliminate ‘outside’ influences
Get rid of weeds, diseases, insects My job as agronomist is to make some combination of CO2, sunlight, and water
transpiration the limiting factors.
Fungicide
Vision Research Park standard fungicide program Propicanozole at 1st post-emerge herbicide application Prosaro/Caramba at ~10% anthesis
Timing is critical
Plant Growth Regulators
Affect plant growth/development in a physiological manner Include plant hormones such as cytokinin, IAA, gibberellic acid, etc. Seed treatment or foliar Many different application timings
Plant Growth Regulators
Many on the market Dozens, hundreds???? Conducted around 10 trials since 2012 Some ‘side-by-sides’ Replicated data from field experiments has not shown any benefit or
detriment on any of the parameters measured (yield, protein, test weight, moisture)
Fertility
Yield potential changed dramatically the last 10 years What’s a “bumper” crop anymore?
80-100 bushel yields not out of the question Fall nitrogen becoming less common—maybe ~10% of acres Majority 100% spring applied Varies by crop Highly dependent on environment
Fertility
Ideal scenario ~60% of nitrogen needs applied in spring at seeding 25% applied as top-dressed urea or streambar 28-0-0 around 5 leaf Remainder (usually 30# actual nitrogen) applied early post-anthesis (7-10
days post 1st flower)
