Liming of acidic soil on smallholder farms is one of the major challenges to enhance crop yields in Ethiopian highlands. This may be attributed to the additional investment cost for liming. Therefore, this study was carried out to investigate the effects of micro-dosing of lime on yield and yield components of potato on farmers field in Banja district, Awi zone, Amhara region. Three methods of lime rate determination and eight treatments on lime rate application were used in the field experiment. The experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. Crop samples were collected and analyzed to evaluate the effect of treatments on yield and yield components of potato. Data were analyzed with SPSS version 22.0 and SAS 9.3. Among the eight treatments, the highest tuber yield of potato was obtained from the application of 15 tha^-1 lime and the lower tuber yield was found from the unlimed plots. The result revealed that, there is no significant difference between micro dose application of lime with other treatments (4.064, 3.57, 2.032 and 1.016 (tha^-1)) in the production of potato tuber yield. Therefore, micro doses application of lime affordable for small scale farmers with a minimum cost of lime.
