1. Foliar Fertilization of Soybeans in MissouriSoybeans may benefit from foliar fertilization during the reproductive phase of growth. Foliar fertilizers consisting of factorial combinations of boron, calcium, magnesium and phosphorus were applied to soybeans every other week for eight weeks beginning at flowering at three locations. The foliar fertilization treatment containing B+Mg (1.0 lb/acre B + 2.0 lb/acre Mg total) and split into four applications at Mt. Vernon and the Delta Center increased yields by 8 and 4 bulacre, respectively. The... |
2. Field Scale Fertilizer Recommendations and Spatial VariabilityFertilizer is usually applied at a single constant rate across a field. However, soil fertility may vary considerably within a field. Soil test calibrations (ie recommended fertilizer versus soil test ) are usually obtained from sites with low spatial variability of soil test values (ex. small plots ). These calibrations are then assumed to be valid for large fields with variable soil fertility. The effects of variable soil fertility on the relationship between average crop yield response, average... |
3. Integrating Multiple-Input Management Systems to Improve Soft Red Winter Wheat Grain YieldContinued improvements in wheat (Triticum aestivum L.) grain yield have cast greater interest on utilizing multiple inputs within enhanced management systems. Less than recommended seeding rates of modern varieties may utilize inputs more efficiently when subjected to enhanced management. The objective of this study was to evaluate plant growth, grain yield, and expected economic profitability for multiple agronomic and nutrient inputs across different production intensity levels....
