Nutritious Nitrogen

Name:

1. Chile pepper yields are maximized under the following fertilizer regime: High nitrogen applications early in the growing season to give the plants an early boost.
   Low to moderate nitrogen applications throughout the growing season.
   High nitrogen applications late in the growing season.
   Low nitrogen early in the season followed by moderate to high nitrogen applications midway and then tapering off at the end of the season.
   High nitrogen early in the season followed by low to moderate nitrogen applications midway and then tapering off at the end of the season.
2. Assuming that plants need a lot of nitrogen to grow and yield lots of chile peppers, why don’t we just add as much nitrogen as we can? Too much nitrogen is wasted and lost, therefore can harm the environment.
   After a certain point, say 150–200 lb N/acre, you don’t see any yield increases.
   Fertilizer is expensive, so even though yields keep increasing with more nitrogen, it's not worth it.
   Both 1 and 2
   Both 1 and 3
3. Why don’t we add a high dose of nitrogen fertilizer during the seedling stage? Too much nitrogen can increase plant vegetation growth but prevent flowering.
   Seedlings can be "burned" by over-fertilization.
   The nitrogen can’t be used fast enough and is lost to the environment through leaching or other ways.
   Both 1 and 2
   All of the above
4. Adding enough nitrogen at the seedling stage means you don't need to add nitrogen after flowering. True
   False
5. If you are planning to add nitrogen anyway, it's not important to test the soil first. True
   False
6. When fertilizing with nitrogen, how can you best pursue a profitable yield while avoiding water contamination? Add no nitrogen.
   Add only as much nitrogen as the plant will utilize when it is needed.
   Add nitrogen in tiny doses, as frequently as possible.
   Make sure your nitrogen comes from an animal source rather than a chemical source.
7. At the seedling stage: Too ____ nitrogen reduces flowering; too ____ nitrogen reduces growth little/much
   much/little
   little/little
   much/much
