Dr. Emmanuel Bassey Effa

Lecturer I
Crop Science
emmaeffa@unical.edu.ng

I joined the service of the University of Calabar in 2010 as an Assistant lecturer, and have moved to the rank of Lecturer I. Presently, I am involved in teaching and research at both under graduate and graduate levels. My area of specialization is Crop production, with an emphasis on horticulture. I am currently, the Faculty SIWES/Year Four Practical Programme Coordinator, and really enjoy working with the practical year students in crop production and management. I am very much interested in research around Neglected underutilized species (NUS) and food security. I obtained a B. Agriculture degree in Crop Science (1998), M.Sc. Crop Science in 2004 and finally a doctoral degree in Crop production in 2012. I have attended several seminars, trainings and workshops and look forward to attending more. Presently, I am hopeful of collaboration in Neglected underutilized species (NUS) and food security.
