In Pennsylvania, a horse-feeding trial examining the palatability of teff cut at vegetative, early flower and late flower stages is just getting started, says Marvin Hall, Penn State University extension forage agronomist.

“I get reports from horse owners that teff is the greatest thing and horses are eating it. Then others say horses won't touch it, so we're trying to figure out if it's something to do with the maturity of teff or not.”

The study will run from January through March.

Hall also completed a seeding-rate study with seven teff varieties planted at 3, 5, 7 and 9 lbs/acre. He didn't find much of a yield difference among the different rates or varieties.

Mike Hunter, Cornell University extension educator, studied the effects of 0, 50, 75 and 100 lbs/acre nitrogen on teff yields over two years. The 50-lb/acre rate was most efficient.
