2025 Cereal Management

Management research in wheat, durum and oats focuses on PGR, topdressing and combined treatments across different moisture environments. Results are connected to Crop Available Water (CAW) and summarized with management maps for practical decision-making.

Research Question

How do cereal varieties respond to PGR, topdressing and combined management under different Crop Available Water conditions, and where do those practices improve performance without adding unnecessary risk?

Environmental Conditions

Starting CAW

Precipitation

Total CAW

Crop Available Water (CAW) provides the environmental context for interpreting cereal management response. Starting soil water is combined with in-season precipitation to determine the applicable moisture environment. Condie Grow broadly classifies low CAW as 0-9 inches, medium CAW as 9-12 inches and high CAW as 12+ inches. The same management practice may produce a different response depending on the amount of water available to the crop.

Treatments

Control

No PGR / No topdress

Untreated baseline used to compare yield, crop height, lodging and other crop responses against the management treatments.

PGR

Moddus

Plant growth regulator treatment used to evaluate crop height, lodging and management response during the crop-height development window.

Topdressing

30 lbs/ac actual N in UAN

Additional in-season nitrogen used to evaluate yield and protein response under different Crop Available Water environments.

Combined

PGR + 30 lbs/ac actual N in UAN

Combined PGR and topdressing treatment used to evaluate whole-system response under different moisture environments.

Results

Crop Available Water

Starting soil water plus in-season precipitation determines the moisture environment used to interpret management response. In this research, the example environments total 8.62 inches, 10.55 inches and 12.15 inches of CAW.

Management Response by CAW

PGR and topdressing response changes as Crop Available Water increases. The management map provides the quick recommendation, while the CAW timeline and trial results provide the supporting evidence.

Durum Variety Performance

The 2025 durum variety trial provides the variety-performance context surrounding the management work and helps identify genetics suited to more intensive management.

Management Implication

Management intensity should be matched to Crop Available Water. Low, medium and high moisture environments do not necessarily justify the same PGR or topdressing decision. Condie Grow pairs the management map with the CAW timeline and trial results so growers can see both the recommendation and the environmental context behind it.
