According to them, unless the problem of weed infestation on farmers’ field is addressed, Africa will not maximize the gains of crop improvement.
The researchers, who are members of the Steering Committee of the IITA Cassava Weed Management project, also commended the Director General of IITA, Dr Nteranya Sanginga for rejuvenating the weeds science program.
The meeting, which was held 18- 19 August 2014, gave kudos to IITA for its new research agenda of investing in weed science and bringing weed science—a very important but often neglected component of agronomy— to the front burner, and for supporting partners in tackling the problem.
“We thank IITA for the equipment given to us under the Cassava Weed Management Project to help find solutions to the problems of weeds,” said Dr J.C. Okonkwo, Executive Director, National Root Crops Research Institute (NRCRI), Umudike, who was also unanimously elected as the Chair of the Steering Committee.
Under the new research focus, IITA committed to revive its weed management research; rehabilitated an office building, procured equipment, and hired staff. The building was commissioned during the Steering Committee meeting by Deputy Director General (Partnerships & Capacity Development), Dr Kenton Dashiell, who dedicated it to resource-poor farmers, especially women and children.
Prof John Adisa Ayoade, Deputy Vice Chancellor, University of Agriculture Makurdi (UAM) commended IITA for investing in weed science and called on other institutions to emulate.
The Deputy Vice Chancellor who represented the Vice Chancellor of UAM specifically urged the IITA Cassava Weed Management Project to include graduate students to develop the critical human capital that would take research on weed science forward considering the fact that current weed scientists in Africa were aging.
Commending IITA for its renewed attention to weed science, Project Leader, Cassava Weed Management, Dr Alfred Dixon reiterated the project’s goal of increasing cassava productivity for at least 125,000 Nigerian farm families through the provision of labor-saving solutions for cassava weeding which is usually done by women and children.
He said IITA and its partners would work to develop state-of the art weed management practices, by combining improved cassava varieties with proper planting dates, plant populations and plant nutrition options. According to him, the project is also focusing on intercropping and tillage research, as well as testing 21 different pre-emergence and 19 post-emergence herbicides at different application rates to discover the best combinations for sustainable weed control in cassava. Dr Dixon explained that integrated weed management practices, including the use of herbicides that meet globally accepted conventions and safety thresholds appropriate for smallholders would be crucial in making weed control in cassava more efficient and effective.
