Effect of soil PH on postharvest pathological deterioration of sweet potato storage roots
(African Journal of Horticultural Sciences, 2008)
Sweet potato (Ipomoea batatas (L.) Lam.) is the world’s seventh most important food crop but its potential to contribute to food security and income generation is limited in tropical developing countries by its short ...
SUSCEPTIBLE ONION GROWTH STAGES FOR SELECTIVE AND ECONOMIC PROTECTION FROM ONION THRIPS INFESTATION
(Karatina University, 2008-03)
The growth of the bulb onion is subject to significant stress and yield reduction caused by sap
feeding onion thrips. In Kenya, the general control recommendation is to spray the crop with
insecticides as soon as the ...
Do Mixed-Species Legume Fallows Provide Long-Term Maize Yield Benefit Compared with Monoculture Legume Fallows?
(Wiley, 2009-11-01)
The deliberate planting of fast-growing N2–fixing legume monoculture species in rotation with cereal crops can be an important source of N for soil fertility replenishment. We hypothesized that mixed-species fallows have ...
Organic and Mineral Input Management to Enhance Crop Productivity in Central Kenya.
(2009-09)
Organic resources (ORs) are important nutrient inputs in tropical agriculture. Combined with mineral fertilizers, they form the backbone of integrated soil fertility management. This study was conducted to determine the ...
Antimicrobial acitivity of extracts from Tephrosia vogelii Hook F.
(2007-01-29)
The dichloromethane extracts of the root and leaf of Tephrosia vogelii Hook F. (Family: Papilionaceae) grown in Kenya, were subjected to antimicrobial assays against Staphylococcus aureus, Escherichia coli and Fusarium ...
Scope for genetic enhancement of the parasitisation potential of four native strains of Trichogrammatoidea sp. nr. lutea Girault (Hymenoptera: Trichogrammatidae
(Taylor & Francis, 2007-09)
In response to emerging interest in commercial mass production of Trichogramma for Helicoverpa armigera biocontrol in eastern Africa, laboratory experiments were undertaken to assess the scope for genetic enhancement of ...
Effect of temperature on the development of Orius albidipennis Reuter, a predator of the African legume flower thrips, Megalurothrips sjostedti Trybom
(2002)
The effects of temperature on the development of Orius albidipennis (Reuter) (Hemiptera: Anthocoridae), reared on its prey, Megalurothrips sjostedti (Trybom) (Thysanoptera: Thripidae), were studied in the laboratory. Nymphal ...
HOST-PLANT ACCEPTANCE, FECUNDITY AND LONGEVITY OF Tetranychus evansi (Acari: Tetranychidae) ON SELECTED TOMATO ACCESSIONS
(2009)
Seventomato (Lycopersicon sp.) accessions wereevaluated for their
resistance to thetomato red spider mite, Tetranychus evansi Baker and
Pritchard, in the laboratory. Data recorded was: (i) trichome density and ...
The Critical Onion Growth Stages For Selective Protection From Thrips Tabaci Lindeman (Thysanoptera:Thripidae) Infestation
(Kenya Agricultural Research Institute, Nairobi (Kenya), 2006-01)
Field trials were conducted during 2000-2001 at KARIandrsquo;s Mwea-Tebere and Kiboko farms to establish the effect of onion thrips, Thrips tabaci Lindeman on onion bulb yields and to identify the critical onion growth ...
