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 ...
Teaching and Learning Resources as Determinants of Students Academic Performance in Secondary Agriculture, in Rachuonyo North Sub County, Kenya
(International Journal of Advanced Research, 2015-09)
In the last decade, performance of students in Rachuonyo North Sub County has taken a downward trend in the national examination, Kenya Certificate of Secondary Education (KCSE).This downward trend is particularly seen in ...
Disparity between Leaf and Root Symptoms and Crop Losses Associated with Cassava Brown Streak Disease in Four Countries in Eastern Africa
(Journal of phytopathology, 2015)
Cassava brown streak disease is endemic to the coastal regions of East Africa, and from around 2004, the disease resurged and became epidemic in the Great Lakes Region, where it continues to spread. In both these areas, ...
Effective Dose of Crude Ethanol and Aqueous Extracts of Phytolacca Dodecandra (L’ Herit) on Anopheles Gambiae (Diptera: Culicidae) Larvae
(bio, 2015-01)
Objective: malaria vector control is either by adult or larvae management. This study reports on the effective dose of crude
ethanol and aqueous extracts of leaf and mature green fruits of Endod; Phytolacca dodecandra (L’ ...
Larviciding Potency of Water and Ethanol Extracts of Phytolacca dodecandra (L’ Herit) on Anopheles gambiae (Diptera: Culicidae)
(Mosquito Research, 2015)
Introduction: Plant extracts are an attractive target for search of effective malaria vector control agents. The reason for this is that they present a cost effective, target specific and bio-degradable insecticides. The ...
Evaluation of advanced wheat (Triticum aestivum L.) lines for stem rust (Puccinia graminis f. sp. tritici) resistance and yield
(International Journal of Agronomy and Agricultural Research (IJAAR), 2015)
Stem rust disease caused by Puccinia graminis f. sp tritici is a major challenge to wheat (Triticum aestivum) production in Kenya and other wheat growing countries of Africa and Asia. The current study aimed at evaluating ...
Optimization of Seed Potato Specific Density, Starch and Dry Matter Contents and Tuberization Capacity of Resultant Plants Through Integrated Irrigation, Nitrogen and Phosphorus Management
(Journal of Plant Sciences, 2015-07-30)
A study was conducted in a Rainshelter (RTrial) at the Horticultural Research and Teaching Farm of Egerton
University to determine the effect of integrated application of irrigation water, nitrogen (N) and phosphorus (P) ...
Disparity between Leaf and Root Symptoms and Crop Losses Associated with Cassava Brown Streak Disease in Four Countries in Eastern Africa
(Journal of Phytopathology, 2015)
Cassava brown streak disease is endemic to the coastal regions of East Africa, and from around 2004, the disease resurged and became epidemic in the Great Lakes Region, where it continues to spread. In both these areas, ...
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 ...
