Dr. Titus Ngmenzuma | Soil Biology | Best Researcher Award

Dr. Titus Yeliku-ang Ngmenzuma’s research focuses on advancing plant–microbe interactions to promote sustainable agricultural productivity through innovative microbial applications. His work spans crop science disciplines including agronomy, plant physiology, soil microbial diversity, and phylogenetic studies, with a particular emphasis on the role of rhizobia in enhancing soil fertility and legume productivity. He has explored genomic biodiversity among native rhizobia in African soils using DNA fingerprinting, coupled with biochemical and functional characterizations to identify strains with strong plant growth–promoting and ecological adaptation traits. His research integrates glasshouse and field evaluations of diverse legume–rhizobium symbioses, assessing nodulation, photosynthetic efficiency, biomass accumulation, and grain yield to determine symbiotic effectiveness. Additionally, he employs nitrogen and carbon isotope analyses to elucidate nutrient cycling and the functional relationships between nitrogen fixation and carbon assimilation in symbiotic systems. Through his interdisciplinary collaborations and mentorship roles, he contributes to developing sustainable biofertilizer technologies and capacity building in microbial ecology and crop improvement. His scientific outputs collectively aim to strengthen agricultural resilience and productivity through environmentally responsible microbial innovations and integrated soil fertility management.
