Abstract:

Soil acidity is one of the soil chemical degradation problems affecting soil productivity in the Ethiopian highlands. So, amendment of these soils is of paramount importance to enhance their productivity. This study was conducted during the 2017 cropping season to determine the effects of lime and phosphorus levels on selected soil properties and bread wheat yield on acidic soils of Pawe Agricultural Research Center Banja sub-station in Awi Zone of Amhara National Regional State. The experiment was laid out in randomized complete block design with three replications. Four levels of lime (0, 3, 4.5 and 6 t ha-1) and four levels of phosphorus (0, 10, 20, and 30 kg ha-1) were combined in a complete factorial arrangement. Lime requirement of the soil was calculated based on its exchangeable acidity. Soil samples were analyzed for Texture, BD, pH, total N, available P, OC, CEC, exchangeable Al and acidity, exchangeable base (Ca, Mg, K and Na). The grain and straw samples were also analyzed for concentration phosphorus. Wheat grain yield, thousand seed weight, biomass yield, number of tillers, plant height, spike length and number of seeds per plant were collected at recommended time. Then data were managed properly using the Excel computer software and subjected to the analysis of variance using the SAS software. Results of soil analysis after one month of liming showed that lime application significantly (p
