Response of Maize to Organic and Inorganic Sources of Nutrients in Acid Soils of Kenya
(2015-07-21)
aize yield in Kericho County, Kenya is limited by infertile acidic soils. The effect of
inorganic sources of nutrients and amendments; triple superphosphate (TSP), calcium
ammonium nitrate (CAN) and lime, were compared ...
Comparison of soil phosphorous extraction by Olsen and double acid methods in acid soils of Western Kenya
(2015-08-21)
hosphorous is an essential nutrient in plants required for root establishment. In the soil, it is
applied as DAP, TSP or phosphate rocks. In acid soils, aluminium and iron are dominant and tend
to “fix” phosphorous, ...
Response of Leucaena leucocephala (Lam.) De Wit (Leucaena) Provenances to Aluminium in Potted Soil Experiment
(2015-08-21)
Aims: To determine the level of acid or aluminium tolerance provenances in Leucaena (Leucaena
leucocephala) a favourite agroforestry tree in Kenya.
Study Design: The set up was a 2-factor (provenance-aluminium) experiment ...
Response of selected sorghum (Sorghum bicolor L. Moench) germplasm to aluminium stress
(2015-08-19)
Sorghum (Sorghum bicolor L. (Moench) is an important food security crop in sub-Saharan Africa. Its
production on acid soils is constrained by aluminium (Al) stress, which primarily interferes with root
growth. Sorghum ...
Effects of lime, phosphorus and rhizobia on Sesbania sesban performance in a Western Kenyan acid soil
(2015-07-21)
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 ...
Phosphorus Sorption and Lime Requirements of Maize Growing Acid Soils of Kenya
(2015-08-21)
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 ...
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 ...
Enhancing Maize Grain Yield in Acid Soils of Western Kenya Using Aluminium Tolerant Germplasm
(2015-07-21)
Abstract: Maize (Zea mays L.) is one of the world’s most important cereals and is a staple food for many people in developing
countries. However, in acid soils (pH < 5.5), its productivity is limited by aluminium (Al) ...
Development of maize single cross hybrids for tolerance to low phosphorus
(2015-08-21)
Low available phosphorus (P) is one of the major hindrances to maize (Zea mays L.) productivity in acid
soils. The objectives of this study were to: (1) develop P-efficient maize inbred lines, (2) develop single
cross ...
