Summer rainfall in Nebraska is uncertain in time and amount, such that yields of potatoes are increased substantially by irrigation where it can be practiced. Rainfall is especially limited and poorly distributed in western Nebraska and eastern Wyoming making irrigation mandatory for commercial production of the crop. The experiments reported here were conducted in that area under sprinkler irrigation with the following objectives:

  1. To study the growth and yield of potatoes with fertilization through sprinkler irrigation.

  2. To evaluate effects of different times and rates of fertilizer nitrogen application on potato production

  3. To measure interaction of applied potassium fertilizer with the above nitrogen treatments on potato production.
