Abstract

Teff grass is characterized by marked plasticity to grows well on a range of conditions, since it adapts well to high temperatures and tolerates drought. The objective of this work was to evaluate N rates and time application on the yield and nutritional quality. Three cuts were made when the plots reached pre-flowering stage. The variables related to yield were Dry matter content (DM), DM yield (DMY) and N use efficiency (NUE). Samples were processed to analyze nutritional quality trough Neutral and Acid detergent fiber (NDF, ADF), DM digestibility (DMDig) and crude protein (CP). Fertilization effects was observed across partial cuts and DMY123 , where 85N rate exceeded the rest. The 35N rate was significantly higher for NUE for cuts 1 and 2, emphasizing the time application. Forage CP increased with N rate, with respect to check 0N. The observed response to N has a practical significance and better moisture condition at sowing was decisive for the initial N use.
