Genetic Variation In Coffee Accessions In Kenya And Introgression From Robusta To Arabica Using Random Amplified Polymorphic Dna And Microsatellites

ABSTRACTCoffee provides one of the most widely drunk beverages in the world, and is a very important source of foreign exchange income for many countries. In kenya, coffee production has a significant contribution to Kenya‟s economy for decades, and a high proportion of the coffee produced is considered the best quality coffee in the world. In coffee, morphological parameters are very often used to discriminate the varieties and hybrids. However, this exercise has some challenges that inclu...

Phenotypic And Genetic Diversity Studies On Selected Rice (Oryza Sativa L.) Genotypes Based On Amylose Content And Gelatinization Temperature

ABSTRACTRice cooking and eating qualities are mostly determined by the grain’s starch content which is composed of amylose and amylopectin. Amylose content is regarded as the most important indicator in classifying rice varieties in terms of starch content. Waxy gene located on chromosome 6 codes for Granule Bound Starch Synthase (GBBS) enzyme which is involved in biocatalysis of amylose synthesis in rice endosperm. In addition, amylopectin content influences gelatinization temperature in r...

Capacity Building And Evaluation Independence Among Public Benefit Organizations In Homa Bay County, Kenya

ABSTRACT Monitoring and Evaluation over time have gained traction and become fundamental components in projects. Most internal evaluations are based on the assumption that evaluators are independent and do not bow to different forms of influence. Literature however reveals cases of evaluators being confronted by stakeholders to either alter or misrepresent their findings. Independence of evaluators at work is therefore at stake. The fear is that unless a solution is found, interferences...

Determinants Influencing The Successful Implementation Of Modern Housing Projects In Mikindani, Mombasa County

ABSTRACT Most of the houses in Mombasa County are poorly constructed and without approved plans by Municipal Council of Mombasa and there are no urban plans for the structures constructed which makes Mombasa as a city surrounded by many shanty structures in the estates. In recent years, a number of financial institutions have encouraged the development of modern housing structures through provision of Financial assistance in form of loans, grants and implemented inform of projects. A go...

Evaluation Of Anti – Aphids Properties Of The Aqueous Crude Fruit Sap Extract Of Solanum Incanum

ABSTRACT The green peach aphid, Myzus persicae is a worldwide aphid species which is responsible for important economic losses. Its feed on more than 50 plant families, causing great losses to agro industrial crops, vegetables, horticultural crops and stone fruits and it is presently categorized as one of the most important agricultural pests worldwide. Conventional insecticides used for aphids control are expensive and arguably associated with various severe adverse side effects hence ...

Bioengineering Maize With C-Repeat Binding Factor 1 (Cbf1) As A Strategy Towards Drought Tolerance

ABSTRACT Africa is a drought prone continent making farming risky especially to small-scale farmers who depend on rain-fed agriculture. Maize is the most widely grown staple crop in Africa with more than 300 million people depending on it as their main food source. Drought leads to crop failure, hunger and poverty and this is being worsened by climate change. There is therefore need to develop drought tolerant maize. Conventional breeding methods have been applied in the development of...

Project Management Practices And Performance Of Agricultural Projects By Community-Based Organizations In Bungoma County, Kenya

ABSRACTKenya‟s economy is heavily dependent on the performance of agriculture which provides the basis for the development of other sectors. However, the performance of many agricultural projects in Kenya is still being challenged in the sense that some projects remain stalled while others get completed late with low returns. Previous studies have dwelt on isolated cases of project management like market access in the agriculture sector, Information access using mobile and M&E in projects. ...

Larvicidal activity and phytochemical composition of crude extracts derived from Vernonia lasiopus, Vernonia auriculifera and Vernonia galamensis against the malaria vector Anopheles gambiae

ABSTRACTMalaria is one of the major parasitic diseases in the tropical and subtropical regions of the world. The World Health Organization (WHO) estimates that each year, malaria causes 300 to 500 million infections and 1.5 to 3 million deaths. The disease accounts for 20% of all global childhood deaths. There are major problems of drug resistance, particularly to chloroquine which has been the mainstay of malaria treatment, especially in Africa because of its low cost and minimal side effect...

Information Communication Technology Considerations And Revenue Collection In Nairobi City County, Kenya

ABSTRACTCounties in Kenya have adequate revenue based in financing their current services, but thecollection levels are often low. Thus the counties are striving to re–engineer strategiestowards improvement of revenue collections since it is their mandate to offer quality andtimely service delivery to the residents and they cannot proceed well without enoughfinances to run crucial activities. The study therefore sought to investigate InformationCommunication Technology considerations ...

Characterization Of Microhabitats Of Arboviral Mosquito Vector Larvae On Three Islands Of Lake Victoria, Kenya

ABSTRACT Mosquitoes are the primary vectors of arboviral infections. As there are no vaccines or effective therapeutic treatments for these diseases, vector control is an important approach for curbing their circulation or transmission. These vectors spend the first three of their four life stages in aquatic habitats where fitness and efficiency of adult mosquitoes to transmit arboviral infections is greatly influenced. Understanding ecology of mosquitoes in their aquatic habitats is the...

Abundance, Genetic Diversity And Symbiotic Potential Of Common Bean (Phaseolus Vulgaris L.) Nodule Associated Bacteria In Western Kenya Soils

ABSTRACTPlant growth-promoting rhizobacteria (PGPR) are beneficial native soil bacteria that colonize plant roots and result in increased plant growth. Those that colonise the nodules of legumes are known as nodule associated bacteria (NAB). The aim of this study was to determine the distribution and genetic diversity of NAB that colonize Phaseolus vulgaris, their abundance, and symbiotic efficiency when coinoculated with Phaseolus vulgaris in Western Kenya soils. The soil samples were collec...

In Vitro Regeneration And Transformation Of Striga Hermonthica (Delile) Benth

ABSTRACT Striga is an obligate root hemi-parasitic angiosperm that causes devastating cereal crop losses to millions of smallholder farmers in sub-Saharan Africa (SSA). The parasite causes the greatest effects on infertile soils thereby directly affecting the lives of the poorest subsistence farmers. The parasite attaches to a host crop‘s roots, and exploits its water and nutrients leading to stunted growth and death. Several cultural control methods including; crop rotation, use of t...
