Winter Wheat Seeding Decisions for Improved Grain Yield and Yield Components

The continual re-evaluation of agronomic practices is necessary to improve crop performance and sustainability the production winter wheat (Triticum aestivum L.), particularly as genetics climate conditions change. Recommendations made about planting dates, spacing, variety, seed rates under normal climatic may not be suitable in current times with more variability. Our experiment investigated effect date (early, historic-optimum, late), row spacing (19 25 cm), variety (Goodstreak, Robidoux, Wesley), rate (1.8, 2.1, 2.3, 2.4, 2.6, 2.8, 3.1, 3.4 M seeds ha?1) on grain yield components. seeding was nested within nested-factorial design. A treatment design used testing at several locations Nebraska across two years. Variety had a substantial (p < 0.05). also interaction 50% time ? 0.01). At Hemingford, for example, Wesley planted 19 cm 5.9% when compared Robidoux (5.5 Mg ha?1). Similarly, biomass influenced by sites 0.01), but occurred between three sites.
