Performance of Leucaena leucocephala, Seedlings in Two Agro-climatic Regions of Kenya
(Journal of Agriculture and Ecology Research International, 2016-02-17)
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 ...
Molecular markers associated with aluminium tolerance in Sorghum bicolor
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, ...
Recent advances towards understanding and managing Kenyan acid soils for improved crop production

Effects of lime, phosphorus and rhizobia on Sesbania sesban performance in a Western Kenyan acid soil
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 ...
Response of Sorghum (Sorghum bicolor (L.) Munch) and Chemical Characteristics of Soil to Organic and Inorganic Fertilizers on Kenyan Lower Midlands Acid Soil
(International Journal of Plant & Soil Science, 2019-05-17)
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 ...
Phosphorus Sorption and Lime Requirements of Maize Growing Acid Soils of Kenya
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 ...
Screening Selected Maize Single Crosses for Tolerance to Low P in Acidic Soils of Bumala and Maseno
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 ...
Breeding Grain Sorghum for Tolerance to Aluminium Toxicity
(Africa Environmental Review Journal, 2020)
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 ...
Micro-Dosing of Lime, Phosphorus and Nitrogen Fertilizers Effect on Maize Performance on an Acid Soil in Kenya
(Sustainable Agriculture Research, 2015-03-17)
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 ...
Genetic Effects for Maize P Efficiency Traits in Acid and Non-acid Soils of Western Kenya
(American Journal of Experimental Agriculture, 2015)
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 ...
