Teff (Eragrostis tef (Zucc.) Trotter) is a well-adapted, fast-growing crop with
competitive forage quality as its nutritive value for livestock fodder is similar to other grasses
utilized as hay or ensiled feeds. Two field experiments were conducted from May to October
2017 in order to determine the effect of cutting frequency on yield and quality of teff (Eragrostis
tef) as fodder crop under Mediterranean climatic conditions. The agronomic performance and
nutritive value of teff was analyzed in order to define alternatives to local forages for animal
feeding in the Mediterranean region. The experiments conducted at two sites (Western and
Central Greece) were laid out in a completely randomized design with three replicates and three
cutting frequencies (10, 20, 30 days’ interval between cuttings - F10, F20, and F30, respectively).
The results of this study demonstrate that the cutting interval has a marked effect on the fodder
yield and quality. The highest total dry matter yield (6,322–6,778 kg ha-1) was found in F10
treatment. In terms of qualitative characteristics, the highest fat levels and lowest ADF levels was
found in F30 treatment, the highest protein levels and the lowest NDF levels in F10 treatment,
and the highest levels of fibrous substances, ADF and NDF, in F20 treatment. Data suggest that
teff could be successfully integrated into Mediterannean grasslands with the prospect for
improving their nutritional quality and the possibility for increasing protein yield through the
application of frequent cuttings.
