“…The highest mean grain yield (2875 kg/ha) was recorded with the soil test crop response-based fertilizer recommendation treatment (table 1) which was significantly higher than the farmer practice (2119.4 kg/ha). The results of this study are consistent with findings of [7] who reported that the highest grain yield was recorded under application of soil p calibration.…”

On-farm verification trial of soil test based crop response phosphorous calibration study for bread wheat production was conducted in 2019/20 main cropping season in the Horo District of the Horo Guduru Wollega Zone. The trial was initiated to verify phosphorus critical level and requirement factor for bread wheat production in Horo District. The treatments were the control (without phosphorus fertilizer), farmers practice (blanket recommendation) and soil test based recommended phosphorus fertilizer rate (RR). The trial was conducted on six farmers' field across the district. Plot size was 10m * 10m. Soil data before planting and yield data were collected throughout the trial. Soil reaction pH (H 2 O) of all the sites ranged from 4.73 to 5.42 and available P ranges from 1.4 to 12.6ppm. Soil acidity of the experimental sites were amended with lime. Bread wheat grain and biomass yield (kg/ha) were high and significantly (p< 0.01) affected by different fertilizer rates used as treatments. The highest grain yield (2875 kg/ha) was resulted with soil test based phosphorus fertilizer rate recommendation. Economically optimum N (46 kg/ha), critical level phosphorus (10 ppm) and phosphorus requirement factor (11.03 kg/ha) for bread wheat production in the district were gained and recommended during the calibration study. It was significantly higher than the grain yield gained from the farmers' practice (2119.4 kg/ha) and control/without phosphorus fertilizer (1647.2 kg/ha). Similarly, soil test based phosphorus fertilizer rate recommendation was economically optimum and feasible for bread wheat production in the district.

“…The yield obtained from the demonstration sites revealed that the maximum grain yield wheat (4110kg/ha) obtained from the application of soil test based Phosphorus fertilizer recommendation (STBFR) and optimum Nitrogen recommended, While grain yield of 3322.67 kg/ha obtained from blanket recommendation. The results of this believe are reliable with discoveries of who detailed that the highest grain yield was recorded under application of soil testing based fertilizer applied [12]. Average biomass and grain yield (kg/ha) as affected by the treatment (Fig.…”

Wheat is a major crop produced in Ethiopian high lands and in particularly in study area, which is a staple food crop. Soil nutrient depletion restrains agricultural crop production and economic growth. A major challenge on recommendations on the amount and type of fertilizers to applied in the country level and in the study area. Soil test based phosphorous calibration study was conducted on bread wheat for three consecutive years for determination of the values of critical level phosphorus (10 ppm) and phosphorus requirement factor (11.03 kg/ha) in Horo District. This District was selected purposively based on potential Bread wheat production. Due to Ethiopia begun to use NPS fertilizer recently, Optimum NPS fertilizer rate for bread wheat production was determined in Horo District. In order to gain confidence in the diffusion of technology to end users, a pre-extension demonstration of the NPS fertilizer recommended rate for bread wheat based on soil tests was completed in the Horo district. The goal of this demonstration was to allow farmers to participate and test the technology during the 2020–21 cropping season. There were two treatments presented: a blanket recommendation and 100% phosphorous critical NPS at optimum nitrogen (46 kg/ha). The research findings were that the soil test crop-based NPS fertilizer rate application from 100% phosphorous critical NPS at optimum nitrogen (46 kg/ha) was recommended for the production of bread wheat in the Horo district. The analysis of variance indicated that, the highest grain yield (4110 kg/ha) was obtained from the application of Soil Test based NPS fertilizer recommendation (STBFR) whereas the lowest grain yield 3322.67 kg/ha from the blanket fertilizer recommendation. The economic analysis also revealed that the maximum net benefit 87089.40 Ethiopia Birr was obtained from STBFR. Soil test based NPS fertilizer recommendation was economically feasible and the highest Marginal rate of return and net income were obtained from soil test based fertilizer recommendation. Therefore, 100% Pc from NPS and Nitrogen 46 kg/ ha fertilizer rate recommended for bread wheat production and productive in the study area. Further scaling up/out the technology to reach more produced in the same soil type and agro ecology in particularly Eastern Wollega Zone and Horo district.
