Occurence, abundance and distribution of banana nematodes in two banana cultivars at different altitudes in banana production zones, Kenya

Research Description

A survey study will be carried out to determine the occurrence, abundance and distribution patterns of banana nematodes on two cultivars of banana at different altitudes in banana producing regions. Also a trial will be set up to determine the pathogenicity of nematode pratylenchus goodeyi to be isolated from infected banana roots collected from a hot and cold area.

Germination and early growth of elite cocoa varieties in Nigeria

Research Description

To test for seedling vigor of seven elite cocoa varieties and an F3 Amazon selected variety for field establishment. This is to analyze which of the hybrid varieties used for cocoa production in Nigeria is best in terms of early growth and vigorous for field establishment after the nursery.

IMPROVEMENT OF CASSAVA GENOTYPES FOR RESISTANCE TO CASSAVA MOSAIC DISEASE AND ROOT QUALITY TRAITS USING MARKER ASSISTED SELECTION

Research Description

Cassava is a vegetatively propagated staple crop with great economic importance for tropical and sub-tropical Africa, Asia and Latin America. Despite the availability of natural genetic diversity in the global cassava germplasm relevant to breeding for increased dry matter, total carotenoid contents and resistance to CMD, improving these traits through phenotype-based recurrent selection is a lengthy process due to the breeding complexities associated with the species. Marker Assisted Selection is a strategy for dramatically increasing selection gains in the recent years. The general objective of this research is to improve cassava genotypes for resistance to cassava mosaic virus and root quality for sustainable cassava production.

Effects of Alternating sequence of herbicide application on three cassava varieties

Research Description

The effect of time of application(3 weeks before planting, 2 weeks before planting,1 week before planting and on planting day) of Sencor plus on three different cassava varieties (TMEB419,IBA 980505, IBA 980581) was evaluated. The research work is aimed at evaluating the best time to apply sencor plus without having injurious effects on the cassava. Data collected include: plant height, weed density, weed bio-mass production, etc. The data will be analysed using SAS and treatment means will be separated using Duncan's Multiple Range Test (DMRT)

Evaluation of some botanicals in the control of Africa Rice Gall Midge

Research Description

Rice is an important cereal crop in Sub Saharan Africa with 4.5% annual increasing rate of consumption. However, its production is limited by infestation of Africa Rice Gall Midge (AfRGM) in which its larvae attack rice at vegetative stage causing 80% to total crop loss in endemic areas. Synthetic insecticides has been used overtime in its management however, its detrimental effect on the ecology necessitate need for an alternative. Botanicals have been found readily available and eco-friendly. This research therefore seek to screen some plant products and to determine their lowest bioactive level against AfRGM.

Socio Economic and Botanic Analysis of West Bank and Block A Forests of IITA, Ibadan, Oyo State, Nigeria

Research Description

The thesis looked at the Socio economic and Botanic analysis of both the west bank and block A forest of IITA, The socio economics analysis aspect of the research looks at the non- timber forest products collected from the forest, their uses, profitability and determinants of NTFPs collected. It also access at the determinants of medicinal plants usage among villagers living at the perimeter fence of IITA and their willingness to pay for forest conservation in their areas. The Botanic analysis aspect of the research captured the floristic composition, structure and demographic pattern of woody plants, diversity and similarities of the two forests

White yam genotypes, growth stages, virus titre and their resistance reaction to Yam mosaic virus

Research Description

This study is focused on establishing a relationship between the YMV titer, growth stages and symptom expression of different D. rotundata genotypes and to device an approach to categorize yam genotypes as resistant, tolerant or susceptible. This knowledge and method would be very valuable for phenotyping yam germplasm for YMV resistance and YMV resistance breeding programs.
