Abstract

In western Kenya soils are acidic and have low fertility. A study was carried out to examine the effectiveness of four recommended soil fertility management practices. There were four treatments, DAP, DAP + lime, MPR + CAN, Rutuba + DAP and a control where no fertilizer was applied. P was applied at the rate of 26 kg P ha, N 75 kg N ha and 60 kg K ha. Application of DAP resulted in pH decline. Minjingu PR and Rutuba commercial organic manure had no effect on the soil pH in Siaya. There was significant increases (p<0.05) in soil pH with the addition of Minjingu PR in Uasin Gishu and Trans Nzoia counties. Siaya county had the lowest maize yields but with the highest response to fertilizer application. Trans Nzoia gave the highest grain yields, but did not show significant differences (p<0.05) between the fertilizer treatments. From the analysis of Minimal Return of Rates (MRR), it is economical to use DAP in Trans Nzoia, a combination of DAP and Lime in Uasin Gishu and MPR and CAN in Siaya county.
