The verification trial of soil test based crop response phosphorous calibration study for bread wheat production was conducted in 2021/22 main cropping season in Bora district of East Shewa zone. The trial was initiated to verify the phosphorus critical level (10 ppm), requirement factor (6.45 ppm) and optimum amount of nitrogen (69 kg/ha) determined during soil test based crop response phosphorus calibration study for bread wheat production in Bora district. The treatments were control (without fertilizer as T1), farmers practice (blanket recommendation as T2) which was 100 kg of urea and 100 kg of NPS and soil test based recommended phosphorus fertilizer rate as T3. The trial was conducted on six farmers’ field across the district and the trial was laid out in randomized complete block design that was replicated over farmers as replications. The plot size was 10 m × 10 m and 150 kgha-1 seed rate was used. Analysis of variance for grain yield and above ground biomass indicated that there was significant difference (P<0.05) between the treatments. The highest mean grain yield (4580 kg/ha) and above ground biomass (11.95 ton/ha) were recorded with the soil test crop response-based fertilizer recommendation treatment which was significantly higher than the farmer practice (3647 kg/ha and 9.67 ton/ha respectively); whereas the lowest grain yield (1938 kg/ha) and above ground biomass (5.84 ton/ha) were recorded for the treatment without fertilizer.
