Development of Nitrogen rate Recommendations for No-till Dryland Grain Sorghum in Virginia
… starter N fertilizer needed in combination with side-dress N applications to achieve economic grain yields, (ii) to investigate if pre-plant broadcast N applications are as efficient as band-placed plus side-dress N applications, (iii) to evaluate the response of grain sorghum yield to …

Investigating Nutrient Management Innovations in Upland Cotton Production to Increase Agronomic Efficiency
… this thesis were to: 1) evaluate the effects of side-dress potassium (K), sulfur (S), and boron (B) formulation and application timing on tissue nutrient levels during the bloom period; 2) evaluate lint yield response of cotton to different formulations of nitrogen (N), K, S and B applied at …

Maximizing corn yield potential through proper rate, placement, and timing of nitrogen fertility
… to the crop as needed. Combining Hydra-Hume with Side-Dress N Applications to Improve N use and Productivity of Corn Split applications of N, in addition to the different methods of split application (Y-drop or coulter) were compared to applying all the N fertilizer preplant to determine which …

Systems Evaluation of Shallow Anhydrous Ammonia Placements, Rates, and Timing on Maize Plant Uniformity, Yield and N Use Efficiency
… in spring just days before planting, 100% side-dress at V6-V7 growth stage, and split NH<sub>3</sub> applications) and four N rates (0, 90, 145, and 202 kg N ha<sup>-1</sup>) were evaluated in a factorial combination. The NH<sub>3</sub> was injected to a depth of 12 cm. Pre-plant …

Plant growth regulators and biostimulants for use in varying management systems to improve corn grain yield
… population, added fertility through nitrogen side-dress and foliar micro fertilizer applications, and provided a fungicide application at the VT growth stage. The PGRs (Ascend SL or Optify/Stretch) were applied in-furrow at planting, and either Ascend SL, or a biostimulant (Toggle or Voyagro) …

Understanding variability associated with corn grain yield response to foliar fungicide application
Quinone outside inhibitor (QoI) fungicide (e.g., pyraclostrobin, azoxystrobin, and trifloxystrobin) fungicide application is becoming a common practice in corn production systems. The strobilurin class of fungicides inhibits mitochondrial respiration in fungal cells, and preventing plant pathogen …

Nitrogen dynamics and biological response to dairy manure application
… alternative application method which addresses these concerns, but likely changes the dynamics of nutrient cycling. Comparison of the two application methods has yielded mixed results and warrants further research. Therefore, the objectives of this research were to contrast the surface …

Cover crop programs, termination methods and timings, and suppression mechanisms on weed growth and competition
… vetch + cereal rye CC was present. A range of side dress nitrogen fertilizer rates, weedy versus weed free herbicide programs, and CC versus no-CC treatments were compared. Overall, yield did not differ among treatments. Ear leaf and grain nitrogen was generally greater under weed free, CC, and …
