A study was conducted to determine the response of Leucaena seedlings planted in two variant agro-climatic regions, Chepkoilel Campus and Maseno in Kenya. The experiment was a 2-factor (provenance – site) split plot ...

Background: Sorghum (Sorghum bicolor, L. Moench) production in many agro-ecologies is constrained by a variety of stresses, including high levels of aluminium (Al) commonly found in acid soils. Therefore, for such soils, ...

Aluminium (Al) toxicity, phosphorus (P) deficiency and low rhizobia populations limit Sesbania (Sesbania sesban) performance in tropical acid soils. The study determined the i) indigenous rhizobia populations that nodulate ...

Soil acidity, low level of nitrogen (N), phosphorus (P) and soil organic matter are major constraints to sorghum production in Kenya. We investigated the effect of farmyard manure (FYM) and combined application of inorganic ...

In Kenya, maize (Zea mays L.) is mainly grown on acid soils in high rainfall areas. These soils are known for low available phosphorus (P), partly due to its sorption by aluminium (Al) and iron oxides. The study ...

Generally, 13% of Kenya’s arable land mass (7.5 million ha) is acidic and prone to poor phophorus (P) availability and soil acidity. This results in crop yield losses due to the direct adverse effects Aluminium toxicity ...

Aluminium (Al) toxicity is a common problem in acid soils where sorghum (Sorghum bicolor (L.) Moench) is grown. It contributes to grain yield reduction of between 30-40 % in sorghum and other cereals. Al interferes with ...

High cost of inorganic fertilizers and lime has precluded their use by smallholder farmers to remedy the problem of soil acidity and infertility in Kenya. To address the problem, we tested a precision technique referred ...

Soil acidity is a major constraint to maize (Zea mays L.) productivity in tropical soils due to toxic levels of aluminium (Al) and phosphorus (P) deficiency. The objectives of this study were ...
