Wheat and Barley Response to Nitrogen Fertilization at Safford Agricultural Center, 2000

Yields of both wheat and barley were increased with the addition of nitrogen and the largest gain was seen when it was applied at the initiation of growth or at boot stage. Effects of applied nitrogen were somewhat masked by the addition of nitrogen through the use of well water. Nitrogen level in the well water added 21 pounds of nitrogen per acre foot of irrigation, adding 48 pounds of nitrogen throughout the growing season. With the low value of grain and the given cost of nitrogen fertilizer, added nitrogen did not increase profitability for the producer
