1. Evaluation of Nitrogen Management Practices in No-till Corn ProductionExperiments were conducted fiom 1995 to 1998 at the Dixon Springs Agricultural Center of the University of Illinois and the Belleville Research Center of Southern Illinois University to evaluate agronomically and economically several nitrogen (N) management options, including the use of the urease inhibitor Agrotaii, in no-till corn production. Compared in these studies were N sources (urea, UAN, ammonium nitrate, and anhydrous ammonia), placement (dribble vs. broadcast for surface-applied N and... |
2. 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... |
3. Exploring the Impact of Temporal Variability in Emergence on Corn Grain Yield and Development PatternsConcerns have raised among farmers in the Midwest regarding the impacts of uneven emergence of corn (Zea mays L.) seedlings. Research has showed that even a minor delay in emergence of a few hours could have a substantial influence on plant performance and ear weight; and one of the contributing factors to uneven seedling emergence in corn is the application of starter fertilizer. Placing fertilizers in the seed furrow increases the salt concentration surrounding the seed and as a result, delays... L. Dorissant, P. Kovács, J. Clark |
