    What You Will Learn

    Current Crop Conditions

    As of September 3, 2024, the harvest of full-season crops in Oklahoma reveals mixed results, particularly with corn and sorghum. Soybeans are struggling significantly, and there is a pressing need for rain across the state.

    Economic Decision-Making

    Producers often grapple with the choice of sticking to historical planting practices versus adapting to current market conditions. Understanding input costs and market prices is crucial for making informed decisions that can impact profitability.

  • Aluminum Tolerance: A Growing Concern in Wheat Production - RDA 313

    Aluminum Tolerance: A Growing Concern in Wheat Production - RDA 313
    2024/08/13
    Wheat Yield and Plant TimingOne of the most surprising insights was that delaying wheat planting can yield results comparable to earlier planting, depending on environmental conditions. This flexibility allows farmers to make informed decisions based on real-time weather patterns.Seeding RatesDr. Silva shared recent studies indicating that increasing seeding rates may not significantly impact yields, particularly with modern wheat varieties. This challenges the traditional belief that more seeds always equate to better yields, prompting a reevaluation of seeding strategies.Nitrogen ManagementProper timing of nitrogen application is crucial for maximizing protein content in wheat, which directly correlates with yield. Understanding the right timing can help farmers optimize their inputs for better outputs.Genetic ImprovementsAdvancements in wheat breeding have produced varieties that are more resilient to stressors like nitrogen deficiency and adverse soil conditions. This genetic progress is vital for adapting to the challenges posed by climate change and soil health issues.Understanding Disease ManagementThe episode highlighted the significant impact of disease management, with fungicide use increasing yields by 10-12 bushels per acre in high disease-pressure environments. This underscores the importance of proactive disease management strategies in wheat production.
