Abstract:
Based on Pc, Pf and optimum level of N fertilizer determined for teff through calibration study made by Zeway Soil Research Center, verification and demonstration activities were under taken during 2013-2014 growing season continuatively to verify and popularize the determined Pc, Pf and optimum nitrogen level for teff at specified area. These verification and demonstration experiments were under taken on 14 and 6 farmer’s field, respectively. Both verification and demonstration experiments had three treatments that include determined/calibrated phosphorus (critical concentration) with recommended optimum N fertilizer for the area, existing NP fertilizer recommendation (blanket recommendation) and one control plot without NP application for teff. The treatments were laid down with RCBD on 10 m by 10 m plot area that was replicated over farmers. The yield were harvested from (5 m by 5 m) plot area and mean comparison of grain yield was also computed at (α
