Improving the fermentation characteristics of corn through agronomic and processing practices
This study determined the influence of corn (Zea mays L.) hybrids, N availability, grain harvest moisture, and drying temperatures on dry-mill ethanol production. Six hybrids, ranging from 92 to 108 d in relative maturity (RM), were planted at two locations over 2 yr. One of four N fertilizer treatments were applied. Grain was hand-harvested at grain moistures of 20 and 25%. Grain was dried to ...

Relationship between Phosphorus and Nitrogen Concentrations in Spring Wheat
Efficient management of P in crop production requires the development of tools to quantify the P status of plants. Our objectives were to establish the relationship between P and N concentrations of spring milling wheat (Triticum aestivum L.) during the growing season and, in particular, to determine the critical P concentration required to diagnose P deficiency. Shoot biomass and P and N ...

Determination of a critical nitrogen dilution curve for spring wheat
Plant-based diagnostic tools of N deficiency can be based on the concept of critical N dilution curves describing whole-plant critical N concentration (Nc; g kg–1 of dry matter [DM]) as a function of shoot biomass (W; Mg DM ha–1). This has been tested for several crops, including winter wheat (Triticum aestivum L.) but has not been tested for spring wheat. Our objectives were to determine a ...
