Conclusions
Introduction Teff is a warm season annual grass
with origins from Ethiopia. It is being
evaluated as an annual hay crop in the USA. The
purpose of this study is to evaluate the optimal
nitrogen requirements for the crop.
The split application of (50 50) 100lbs N/acre
treatment resulted in the highest yield. The 100
lbs acre treatment resulted in a 6 DM tons/acre
yield as shown in figure 1. The 100 lbs N/acre
treatment was significant higher compared to the
0 , 50, and 75 lbs N/acre treatments but not
different than the 150 lbs/acre treatment. Crude
protein percent increased with all nitrogen
treatments, however, only the 100 and 150 lbs/a
treatments were significantly higher than the
check.

• Nitrogen, in the form of ammonium sulfate (AMS),
  will be applied to a Teff trial at
• 0 lbs
• 50lbs
• 75lbs
• 100lbs
• 150 lbs
• N/acre in a RCBD trial with four replications
  seeded June 15. Fertilizer will be applied by
  hand. Nitrogen rates of 100 and 150 will be
  applied half at first emergence and half
  following first cutting. The 0lbs N/acre rate s
  received 36 lbs S/acre to offset the effect of
  sulfur at the 150 lb N rate of ammonium sulfate
• Trial size of the plots are 5 ft wide at a
  seeding rate of 8lbs/acre.
• Data that will be collected from the nitrogen
  rate trials are
• Forage dry matter yield for each cutting.
• Forage quality of each cutting.
• Harvest will occur near or at boot stage.

Objective To compare the effect of N fertilizer
rate and timing upon teff yield and forage
quality.

Teff showed a response to the different nitrogen
rates that were applied as shown in figure 1. The
total of the three cuts showed that the
application of 100lbs N/acre showed the best
results. The 100lbs N/acre is a split application
of nitrogen , half applied at emergence and half
after first cut.
