Dr. Tejendra Chapagain

Dr. Tejendra Chapagain is a Research Associate at the Department of Plant Agriculture at the University of Guelph, Canada, and the Canadian Project Coordinator for SAKNepal. Dr. Chapagain originates from Nepal, and subsequently received a PhD in International Agriculture from the University of Tokyo, and a second PhD in Plant Science from the University of British Columbia (UBC). He is an agronomist by training and brings a wealth of technical expertise in his discipline as well as experience working with subsistence farmers.

Dr. Chapagain has led agricultural research and development projects in Canada, Japan and Nepal aimed at designing innovative practices in field crop agronomy and soil productivity with emphasis on developing adaptive measures to climatic extremes. His research interests include development of new knowledge leading to science-based solutions that: 1) optimize nitrogen requirements of major field crops grown in Canada and developing nations, using the 4R principles; 2) help design low cost and sustainable agro-ecosystems that reduce the use of synthetic fertilizers in crop production, replacing them with more natural, biological resources; and 3) provide tools and practices that sustain ecosystem services, input efficiency and environmental quality, while adapting to  climatic extremes, with a focus on North America, South Asia and Sub-Saharan Africa. General areas of his interests include cropping system research focusing on carbon sequestration, intercrop interactions, nitrogen use efficiency, land and water productivity, root physiology, biotic and abiotic stressor resistance and edaphic selection.
