ABSTRACT
The one year field study evaluated the effectiveness of
cattle manure (CM), nitrogen (N) and phosphorus (P)
fertilizers on some soil chemical properties and maize (Zea
mays L.) grain yield in Migori County, Kenya. CM was
alkaline and of good quality, likely to increase soil pH and
mineralize to release N and P to soil solution. The soil was
acidic (pH = 5.5), had low Ca, N, P and C. CM increased soil
pH by 9 to 15%, P by 7 to 9%, N by 17 to 60% and C by 22 to
36% while the inorganic fertilizers reduced soil pH by 4 to
6%. N and P fertilizer increased soil N by 50 to 120% and P
by 7 to 14%. Grain yield increased by 36, 108, 157, 189 and
203% due to 2 tons CM, 26 kg P+75 kg, 2 tons CM 26 kg P+75
kg N, 52 kg P+75 kg N and 2 tons CM+52 kg P+75 kg ha-1,
respectively. Organic and inorganic materials have the
potential to increase maize grain yield on tropical acid
soils with low N, P and organic matter such as reported in
this study. 2 tons CM+52 kg P+75 kg N ha-1 was
most suitable for soil fertility replenishment necessary for
high maize grain yield.
