Increasing soil acidity is a major cause of low soil fertility in western Kenya where about 57,670 hectares is acidic. While liming can increase soil pH, the most appropriate method of application needs to be determined. This study aimed at determining the best method of applying lime by comparing three methods, Broadcasting, Banding and Spot, using four lime rates (0, 2, 4 and 6 t ha-1) in North Kakamega and Siaya districts and using maize as a test crop. One time application of lime using the three methods was done during planting with 26 kg ha-1 phosphorus and 75 kg ha-1 nitrogen applied as blanket. Data were collected on percentage seed emergence, crop height, tissue chemical composition and grain yield. The results indicated low germination percentage with 6 t ha-1 of lime applied via spot (85.2-94.8%) as compared to control (91.8-98.1%). The heights taken 67 days after sowing were 43% higher than control for 6 t ha-1 banded lime plots in North Kakamega district and 38.07% higher than control for 4 t ha-1 broadcast lime in Siaya district.
