  Nitrogen and phosphorus fertilizers are the major limiting factors for crop production in soils of the study area. In previous years’ soil test-based phosphorus calibration studies were conducted in the Sinana district, and 46 N kg ha-1, P critical (4.60 ppm), and P requirement factor (20 ppm) were recommended for food barely production. In this study, an on-farm field experiment was conducted to verify the Phosphorus Critical (Pc) level and Phosphorus requirement factor (pf) determined during soil test crop response based phosphorus fertilizer calibration study for food barely production in 2022 bona (July to December) main cropping season. The treatments and experimental setup included (1) Control (without fertilizer), (2) Blanket recommendation (farmer practices), and (3) Soil test crop response-based phosphorus recommendation results. Improved food barely Adoshe variety used.. View More»
