Effect of Reduced Tillage and Mineral Fertilizer Application on Maize and Soybean Productivity
(2012)
Reduced tillage is said to be one of the potential ways to reverse land degradation and ultimately increase the productivity of degrading soils of Africa. We hypothesised that crop yield following a modest application of ...
Characterization of Uromyces appendiculatus isolates collected from snap bean growing areas in Kenya
(Academic Journals, 2012-11-02)
Bean rust (Uromyces appendiculatus (Pers.:Pers.) Unger var. appendiculatus) is one of the most devastating and variable pathogens of common bean (Phaseolus vulgaris L.) worldwide that can cause total crop loss. Characterization ...
New sources of resistance to spotted stem borer, Chilo partellus in sorghum
(2012)
The lepidopteran Chilo partellus Crambid, an introduced pest in East and southern Africa from Asia, is the most economically important stem borer species infesting cereals in Africa. Chilo partellus causes more than 40% ...
Effect of Bt cotton expressing Cry1Ac and Cry2Ab2 protein on soil nematode community assemblages in Mwea, Kenya
(2013)
Objective: The nematode community structure in soil cultivated with Bt cotton (containing
Cry1Ac and Cry2Ab2 protein), isoline (non Bt cotton) and HART 89M (non Bt cotton) was
evaluated in a field trial at Ndomba in the ...
Screening for Water Deficit Tolerance, Relative Growth Analysis and Agrobacterium-Infectivity in Tropical Maize [Zea Mays L.] Inbred Lines in Nairobi, Kenya
(2014-10)
The gap between maize demand and regional supply is increasing as small-holder farmers grapple with many challenges, key among them drought. Research in identifying maize lines that are tolerant to water deficit and that ...
Novel source of sorghum tolerance to the African stem borer, Busseola fusca
(Academic Journals, 2012-08)
Sorghum (Sorghum bicolor) is an important cereal food crop in semi-arid tropics, but its productivity is curtailed mainly by insect pests and diseases. The African stem borer, Busseola fusca Fuller (Lepidopteran: Noctuidae), ...
Genetic diversity of Faidherbia albida (Del.) A. Chev accessions held at the World Agroforestry Centre
(Taylor & Francis, 2015-06)
This study assessed the extent and distribution of genetic diversity of 29 Faidherbia
albida provenances from 10 African countries by employing amplified fragment length
polymorphism with an aim of providing crucial ...
Specific Energy Consumption of Onion Slices During Hot-air Convection, Infrared Radiation and Combined Infrared-Convection Drying
(AENSI Journals, 2014)
Total energy requirement and specific energy consumption for drying of onion slices
were evaluated using various drying methods including hot-air convection, infrared
radiation and hot air convection-infrared combination ...
Humidity Control System for Wine Maturation Structures
(2013-12-13)
Abstract. Fogging systems can be used to maintain the high humidity required in wine aging structures at acceptable levels during the day and as long as temperature inside the wine maturation store is rising. However, as ...
Conservation tillage, local organic resources and nitrogen fertilizer combinations affect maize productivity, soil structure and nutrient balances in semi-arid Kenya
(Springer, 2011-01)
Smallholder land productivity in drylands can be increased by optimizing locally available resources, through nutrient enhancement and water conservation. In this study, we investigated the effect of tillage system, organic ...
