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. Agronomic Management of Nitrogen to Reduce N2O Emissions in ManitobaNitrous oxide (N2O) emissions from soil accounts for about 20% of Manitoba’s total greenhouse gas (GHG) emissions. Numerous and recent field research has evaluated these emissions as influenced by nitrogen (N) management practices – such as use of enhanced efficiency fertilizers (EEFs), fertilizer placement and timing, use of legume and cover crops and organic farming. Several practices result in considerable decreases in N2O emissions, across a wide... J. Heard, M. Tenuta |
