“…Neither irrigation (2.75 and 2.60 tons/acre for the full and limited irrigation treatments, respectively, P > 0.78) nor nitrogen treatment had any effect on total DM yield (2.52, 2.66, and 2.85 tons/acre for Single60, Single90, and Split20 nitrogen treatments, respectively, P > 0.44) and there were no interactions. Teff dry matter yields measured in this study were similar to or slightly lower than those measured elsewhere on a per‐harvest basis (7,8,9).…”

“…Hunter et al (9), in the northeastern USA, reported a yield increase of 0.7 tons/acre for the first 50 lb N/acre. Hancock and Durham (8), in the southeastern USA, concluded that the yield benefit of 25 and 50 lb N/acre rates was 8.55 lb DM/acre per lb of applied N/acre with no additional benefit from 75 or 100 lb N/acre. Abaye et al (1) reported no yield improvement from 80 to 120 lb N/acre in a single application, single‐cut system.…”

“…In the northeastern USA under rainfed conditions, highest teff yields were similar to sorghum‐sudangrass, but it ranged from <1 to nearly 5 tons/acre, depending on the number of harvests (7,9), which is consistent to forage yields in Oklahoma (6). Under irrigation, teff yielded from 4 to 6 tons/acre when cut twice in the northwestern USA (16), but when teff was irrigated to supplement precipitation in the southeastern USA, yields were less than 2.13 tons/acre for a single‐cut, being 30 to 50% that of other summer annuals grown in that region (8).…”

“…Although information is still lacking about its response to nitrogen fertility (6,8), teff apparently is more N‐efficient than sorghum‐sudangrass in N‐deficient systems (9). It has a low nitrogen requirement with no yield benefit from greater than 80 to 90 lb N/acre/year (1,18).…”

Interest exists in using teff [Eragrostis tef (Zucc.) Trotter] for horse hay in the southwestern USA. Randomized complete block studies in 2007 and 2008 at New Mexico State University's Agricultural Science Center at Tucumcari compared teff forage yield and quality when all or alternate furrows were irrigated (full or limited irrigation, respectively) after the first harvest, with nitrogen treatments [60 or 90 lb N/acre preplant (Single60 and Single90, respectively) and 30 lb N/acre preplant and after the first two harvests (Split30)]. Neither irrigation nor nitrogen treatment affected yield (2.75 vs. 2.60 tons/acre for full and limited irrigation, respectively). Split30 had greater forage crude protein (P < 0.05) compared to Single60 (14.05b, 15.67ab, and 16.61a% crude protein for Single60, Single90, and Split30, respectively). Teff nonfiber carbohydrates (NFC) were higher than reported elsewhere with Single60 being lower than Single90 and Split30 (17.65b, 19.56a, and 18.82a% for Single60, Single90, and Split30, respectively). Teff yield and quality may be optimized with a preplant application of 90 lb N/acre and approximately half the irrigation typically applied to alfalfa in the southwestern USA. Due to inconsistencies among studies, teff NFC should be analyzed before feeding to obese horses or those with metabolic disorders.

“…Management information for grain production in low rainfall areas such as Ethiopia are not applicable for forage production in more humid regions of the USA. Hancock and Durham (1) reported low forage yield of teff in the state of Georgia. Researchers in New York state found that teff needs 50 lb N per acre per cut for maximum DM Yield (2).…”

Teff grass increases summer forage availability in the Rolling Plains of Texas

Teff [Eragrostis tef (Zucc.) Trotter] grass has gained popularity in the United States as an emergency summer forage for livestock due to its drought tolerance and rapid growth habit. An alternative forage would benefit Texas Rolling Plains growers due to the summer forage shortage caused by drought conditions. However, among the teff research conducted in the United States, there is great variability in the forage yields and nutritive values depending on the amount of nitrogen and available water. The objective of the study was to evaluate forage productivity and nutritive value of teff in the Texas Rolling Plains under irrigated and dryland conditions with two nitrogen rates and application timings. Nitrogen fertilizer treatments included single applications of either 50 or 100 lb a−1 applied at planting and a split application of either 50 or 100 lb a−1 applied both at planting and after the first harvest. No differences were observed among nitrogen rates and application methods in the irrigated trial (5286 lb a−1). The split application of 100 lb a−1 produced the greatest total yield in the dryland trial (3096 lb a−1) with no yield advantage of 100 lb N a−1 over 50 lb N a−1 at the first cutting. Forage nutritive values were similar to the warm‐season forage species utilized in the region. This study showed that teff can be an alternative forage species in the region. Future research will include planting dates, nitrogen application timing, cutting height, and the interaction of these factors on yield and nutritive values of teff.
