Effectiveness of Communication Channels and Smallholder Farmers’ Adoption of Improved Legume Technologies: A Case of Morogoro Region, Tanzania

Research Description

The study adopted a cross-sectional research design whereby data were collected once from Gairo and Mvomero Districts, Morogoro, Tanzania. A total of 400 respondents participated in this study of whom about two thirds were from the area of intervention. Smallholder farmers’ awareness differed across the treatments. Factors significantly associated with smallholder farmers awareness were availability of legume technology intervention (P<0.01) and total revenue from income generating activities (P<0.05). More than two thirds of the farmers were willing and ready to pay for at least one technology. Generally, the surveyed farmers had moderate uptake for improved bean technologies.

EFFECTS OF WEED DENSITY AND SPECIES DIVERSITY ON CASSAVA (Manihot esculenta Crantz) YIELD IN ZAMBIA

Research Description

Cassava (Manihot esculenta Crantz) an important crop for food and income security is challenged by weeds. Effective weed management depend on study of weed diversity. A study was conducted in Zambia to determine, weed diversity, Critical Period for Weed Removal (CPWR) and yield loss. Two weeding regimes and sampling was done within 21-168 Days After Planting (DAP). Findings revealed that CPWR was between 42 and 105 DAP; Forty weeds species were identified, Shannon diversity index was 3.487 and yield loss 99.9% under uncontrolled weed condition. Keeping the crop weed free the first four months of growth reduce Cassava yield penalty.

Effect of landuse status and microbiome differences on biocontrol of tomato bacterial wilt disease

Research Description

My research topic 'Effect of land use status and rhizosphere microbiome on bio-control of tomato bacterial wilt disease' is aimed at determining influence of previous land use status that is forest, fallow and cultivated land all of which are characterized by different properties that is biological,physical and chemical which will be assessed during the study. It will also involve a detailed study about rhizosphere microbiome using molecular methods to determine the differences in land uses. Tomatoes will be planted in both natural and wilt pathogen inoculated soils and 4 bio controls assessed for their effectiveness for control of the disease.

Floral biology and crossability studies for improving matooke and mchaare bananas for smallholder farmers

Research Description

Matooke and Mchare cultivars of banana play a very important socio-economic role in the livelihoods of smallholder farmers in East Africa. However, pests and diseases significantly reduce the crop yield thus, directly affecting the livelihoods of the banana farming communities. Consumer acceptability of new banana hybrids is a major obstacle in the current banana conventional breeding endeavors, thus, improving the existing cultivars is a viable option. However, most of the popular cultivars are sterile and hardly set seed – which makes conventional breeding difficult. My research is therefore geared toward overcoming barriers to seed set and increasing banana breeding efficiency.

Impact of adoption of improved cassava varieties on yield and poverty reduction in Oyo and Osun state of Nigeria

Research Description

The fact that IITA has bred lots of cassava varieties to alleviate poverty of rural farmers cannot be denied. Hence this research topic tries to establish in facts and figures how the IITA improved cassava varieties have helped to raise rural farmers productivity and reduced poverty especially in Oyo and Osun where Cassava is the major staple food.

Genetic Analysis of anaerobic germination in rice (Oryza spp)

Research Description

Rice feeds more than half of the world's population but there is a wide deficit in the supply of rice against global demands. More resource efficient methods of rice production are needed. Direct seeded rice is such a method where rice is seeded directly into the field and flooded immediately. This reduces production cost as well as affording earlier harvests. However, flooding creates an anaerobic environment during germination and not all rice varieties can germinate under such conditions leading to poor seedling establishment and yield loss. My research focuses on selecting flood tolerant accessions of Oryza glaberrima, identifying the quantitative trait loci controlling the trait and facilitating their use in marker assisted breeding for development of flood tolerant rice varieties.

Farm productivity and extent of adoption of CSA practices among cocoa farmers in Ghana

Research Description

The cocoa farmers of Ghana not only have high perception regarding the changing climatic conditions but also is very much aware of its effect on their activities. The younger population unlike the older generation are more open towards to new technologies and practices such as rain water harvesting. Education has a high influence on the adoption of practices such as mulching and spacing. Lack of technical knowledge seems to be the most limiting factor for farmers for adopting a particular practice.In the light of changing climatic conditions, more and more farmers are also opting crop diversification over cocoa.
