Small RNAs as the basis for epigenetic modification of phenotypes of Cassava (Manihot esculenta)

Research Description

"DNA provides the blueprint that is transcribed to RNA, which is further translated to proteins. The proteins regulate the biological processes and mechanisms in living organisms including the phenotypes of plants. Phenotypes are thus influenced by the changes in the underlying DNA sequence. However, a number of other factors have been implicated to influence heritable traits in plants without changes to the underlying DNA sequence. One of these factors is small RNAs. We study the small RNAs in Cassava that contribute to epigenetic changes, the specific roles performed and the phenotypic effects on Cassava."

Impact of Climate Change and Technological Innovation on Cereal Farmers' Risk Behaviour in Nigeria: A Gender Approach

Research Description

The research focus on investigating the risk behaviour of farmers to adoption of maize innovations intended to help farmers combat the risk of climate change. Literature evidences suggest that many innovations, intended to improve farmers productivity and welfare ended up not being adopted as expected by the beneficiaries, my research focuses on why? By using both quantitative and qualitative techniques, the research will seek to find answers to how innovation adoption can be facilitated by understanding the risk behaviour of farmers. The research will employ modelling techniques as well econometric techniques to understand farmers behaviour and it’s determinants.

Influence of compost, lime and NPK15:15:15 on soil properties and performance of some cassava varieties

Research Description

Nigeria is the largest producer of cassava in the world yet her production per hectare is among the lowest in the world and one of the major reasons for this decline is the low fertility status of the soil as a result of continuous farming on the same piece of land. The essence of this research is to sustain the fertility of the soil while maximizing production through the complementary use of organic and inorganic fertilizers as nutrient source.

Effect of fertilizer application on growth and yield of White guinea yam (Dioscorea rotundata )

Research Description

Yam is an economically important food crop in the tropical countries especially in West Africa, South Asia and Caribbean. It is usually the first crop to be planted after the land clearing due to the high fertility requirement of the crop.There is little or no information concerning the amount, timing and a particular nutrient needed to the growth period of yam. However, there is a need for information that could enable farmers to know best recommended fertilizer and time of application at the different stages of growth period. The research focused on to develop appropriate fertilization technology management to determine the amount, time and pattern of nutrient uptake and partitioning during the growth period of Dioscorea rotunfata for high yield.

INFLUENCE OF PSYCHOLOGICAL, SOCIO-ENVIRONMENTAL FACTORS, AND FARMERS’ FIELD SCHOOL ON WEED MANAGEMENT CONTROL AMONG CASSAVA FARMERS

Research Description

There has being a paucity of literature on the evaluation of farmers Psychological and their Socio-environmental factors based on the transfer of new agricultural knowledge. The study seeks to examine if there is any significant difference/relationship between psychological, socio-environmental factors and Farmers’ Field School as related to the stated objectives of the study. The transfer of knowledge on new weed management technologies is an important tool to improved productivity but there is a need to understand other factors that might influence the adoption/acceptance of this transfer negatively or positively hence this study.

Cassava dehydration and drying

Research Description

From kinetics study viewpoint, cassava dehydration as a technique to reduce water content prior to drying, is critical in reducing enenrgy requirements, while retaaining much of its nutritional properties. Suitable equations can be derived to predict mass Transfer Parameters during Dehydration and drying. Also, foaming cassava could extend value-web of the crops utilization potentials. Effects of these on properties of cassava in food use (techno-functional, physicochemical, organoleptic, nutritional, etc) is of particular interest.

Analysis of Diversity and Drought Tolerance in Some African Yam Bean Accessions ((Sphenostylis stenocarpa (Hochst.Ex A. Rich) Harms)

Research Description

Eunice is a Masters student with University of Ibadan in Nigeria and a Research Fellow with Genetic Resources Center in International Institute of Tropical Agriculture. She is currently working on analysis of diversity and screening to identify drought tolerant genotypes among some African yam bean accessions through phenotyping. African yam bean is an underutilized legume capable of ensuring food security and improving nutrition and income generation. The crop produces nutritious seed, an edible underground swollen root, feed for animals while restoring the fertility of the soil through Nitrogen fixation. An understanding of the diversity existing among available AYB accessions and identification of genotypes with desirable traits will facilitate the development of suitable parental lines for genetic improvement in the crop. This can aid in commercial utilization to achieve food security especially to the rural poor.

Evaluation of African Yam Bean (Sphenostylis stenocarpa (Hochst. Ex. A. Rich Harms) Accessions for Resistance to Fungi Diseases and Molecular Characterisation of the Pathogens

Research Description

African yam bean (AYB) has been identified to have the potentials in contributing to food security in sub-Saharan Africa , but the seeds have been reported to be heavily infected with quite a number of pathogens and its inability to produce high grain yield is one of the major limiting factors of production. Conventional methods such as the culture-based morphological approaches have been the most common tool used in the identification of plant pathogenic fungi, which has several of limitations such as the inability to culture obligate fungi, to perfectly identify fungi to the species level and to properly quantify the pathogen. In order to meet these challenges, it is imperative to conduct an extensive and reliable research to detect and quantify pathogens responsible for this huge loss in AYB production. Such research should be directed towards the use of a better approach, which is much faster, specific, sensitive, and more accurate to detect the pathogens. Moreover, the detection and proper identification of plant pathogens is one of the major strategies for controlling diseases in plants . Thus, in this present study, molecular tools will be used to characterize the fungal pathogens present in some accessions of AYB. It is also important to develop environment friendly control measures. Host plant resistance has been reported to be favourable in reducing crop loss for environmental, economic and social reasons. Hence, to identify host resistance in AYB there is need to screen different accessions under natural condition to observe their response to pathogen attack. It is expected that the information obtained from this study can be used for the improvement of this crop.
