Minimizing the continuous maize penalty through intense management
As maize prices escalate with increasing demand for grain resulting from recent legislation mandating renewable fuel production, more Midwest farmers are interested in producing maize continuously. Increasing or maintaining maize yield levels becomes a challenge in continuous maize systems due to …

Lignin and carbon transformation in roots of maize and mixed perennial biofuel crops
… being explored as biofuel crops alternative to maize. In this study, fertilized and unfertilized mixed perennial prairie crops were compared with a conventional maize-soybean rotation and to continuous maize cropping systems to assess the potential production of above- and belowground lignin. …

Goss’s wilt and leaf blight of corn: chemical control, residue management and resistance
… in Illinois due to factors that include continuous maize rotations, reduced tillage which increases debris harboring inoculum and the use of susceptible hybrids. There are several ways that could help control the spread of Goss’s wilt, including chemical control, residue management and …

Evolution of energy storage traits in symbiotic rhizobia
… about how natural selection might act on continuous variation in the amount of PHB that rhizobia acquire during symbiosis. The first chapter assesses the extent of heritable phenotypic variation within natural rhizobia populations interacting with soybean (Glycine max) and partridge pea …

Advancing plant transformation and CRISPR/Cas editing: Strategies for recalcitrant maize
… by labor-intensive procedures, particularly maize genetic transformation, which takes 165 days. Given the escalating requirements for genetic transformation and gene editing, there is a growing imperative for the development of a more efficient genetic transformation process. In addition, the …

A model of nitrate leaching from agricultural systems in the northern neck of Virginia
… to soil and climatic factors, explicitly for maize or wheat. VTCROPS simulates soybean in a crop rotation empirically accounting for leaf area and root growth. The model is capable of simulating long-term cropping sequences under minimum and conventional tillage practices for continuous maize …
