Abstract

Calibration of soil test P could be a stage in determining P fertilizer rates to meet plant P requirements and soil nutrient availability of phosphorous. The objective of this study was to determine the critical phosphorous (Pc) and phosphorous requirement factor (Pf) for maize production in the district. Field experiments, which were laid out in a randomized complete block design (RCBD) with three replications, were conducted from 2018 to 2021. Maize response to different levels of phosphorus was conducted at 17 sites in the Sibu Sire District, East Wollega Zone, Oromia Regional State, during the 2019/20 and 2021 cropping seasons. Partial budget analysis showed 138 kg/ha of N was economically optimal for the production of maize in the Sibu Sire district. The phosphorus calibration study included the application of 0, 10, 20, 30, 40, and 50 kg P ha^-1 with a recommended 138 N kg ha^-1 The critical concentration and requirement factor of phosphorus on maize in the study area were 10 mg kg⁻¹ and 20.63 kg/ha, respectively. Using the calibrated phosphorus would enhance the profitability of maize production across the Sibu Sire district. This phosphorus requirement factor and critical phosphorus level can help give recommendations based on soil test phosphorus levels for maize production in the Sibu Sire district. Thus, in soils with an available P status below 10 mg kg^-1, the yield of maize could show a significant response to applications of P fertilizers. Whereas in areas with soil available P status greater than 10 mg kg^-1, the P concentration in the soil sufficient crop growth so further addition of P fertilizer may not result in a profitable yield increase. In addition, integration of this finding with other uses of biofertilizer, compost, vermicompost, and organic fertilizers is a basic to moving forward with yield, maintenance, and sustainability of soil health. Future research should focus on verifying results on farmland before implementing the technology in real-district agriculture.
