Field experiment was carried out on 6 farmer’s field to determine the effect of NPS and nitrogen on yield of teff. The study was conducted using three NPS levels (0, 100, and 200 kg ha-1) and six levels of nitrogen (0, 23, 46, 69, 92 and 138 kg ha-1) and the treatment was laid out in a randomized complete block design with two replications. The analysis of showed that yield of teff was significantly (p < 0.05) affected by the interaction effect of NPS and N fertilizer rates. However, biomass yield of teff was not significantly (p < 0.05) affected by the interaction effects of NPS and N fertilization. The highest biomass (5.600 ton/ ha) was obtained in response to application of 200 kg of NPS and 92 kg of N ha-1. While, the highest teff yield (1592 kg ha-1) was obtained from application of 200 kg NPS with 138 kg N (ha-1). But it is not economically profitable. Therefore the net benefit 45,278 Birr ha-1 which was obtained from application of 100 kg NPS and 46 kg N (ha-1) fertilization is profitable and recommended for teff in Bora District and areas with similar soil type and agro-ecological conditions.
