1. The Influence of Nitrogen Rate and Foliar Fetilization on Yield and Nitrosamine Levels in Burley TobaccoMany burley tobacco (Nicotiana tabactm~ L.) producers believe that additions of nitrogen (N) rates greater than those recommended by university extension senices will result in increased yield and income. In addition to high rates of N, many producers feel that additional foliar fertilizer will further increase yield and quality of burley tobacco and result in greater revenue. Concerns with excessive N additions include improper curing, elevated levels of tobacco specific nitrosamines (TSNA's), undesirable... |
2. Genotype Specific Management for Nitrogen Use Efficiency in Kentucky Soft Red Winter WheatThe complex interaction of genotype x environment x management (GxExM) that defines crop yield is often only explored with research on a single genotype or a select few genotypes. Improvements in crop management and understanding local adaptation to climate variability will require a broader understanding of specific genotype interactions with management systems across multiple environments. A multi-year study investigating the potential for variety specific management systems based on phenotypic... |
3. Management Practices to Minimize Edge-of-Field Phosphorus LossManaging agricultural phosphorus (P) loss at the edge-of-field is critically important to inhibit the development of algal blooms in freshwater bodies. This is particularly important in the Northern Central region which has an abundance of freshwater lakes, agricultural lands, and harmful algal blooms. Edge-of-field monitoring data allows us to take a broad look at how management affects P export from cropland. Looking across a region over several decades also allows us to evaluate the non-management... L. Pease |
