Tech tools scale up cassava weed management knowledge to farmers


The various digital tools developed by the International Institute of Tropical Agriculture (IITA) to scale agronomic recommendations and help farmers improve productivity are currently changing the face and practice of agricultural extension in Nigeria and Africa as a whole.

This assertion was made recently by the IITA Digital Extension and Advisory Services Specialist, Godwin Atser, while delivering a contract review seminar entitled: “Digital disruption in the scaling of the Six Steps to Cassava Weed Management & Best Planting Practices toolkit.”

During the seminar, Godwin took his online audience through vivid explanations of how the digitisation of the project’s Six Steps to Cassava Weed Management toolkit, created by the IITA Cassava Weed Management Project, was revolutionising the art, science and practice of dissemination and agricultural extension services.


The Six Steps to Cassava Weed Management and Best Planting Practices toolkit, popularly called “Six Steps,” is a complete package that addresses all aspects of good agricultural practices in cassava production, which is helping farmers to double their cassava yield to more than 20 tonnes per hectare from the current national average of nine per hectare.

The toolkit prescribes best bet practices in site selection, weed identification, herbicides application, tillage operations, weed management, plant spacing, post-emergent weed management and cassava agronomy principles. The Six Steps have been fully integrated into AKILIMO, a comprehensive digital advisory service for cassava.


According to Godwin, some of the digital tools created to scale out the “Six Steps” include the IITA herbicide calculator, an app which helps farmers and spray service providers to estimate correctly the amount of herbicides to be added to knapsack sprayers to prevent herbicides overdose or under-dose; the cassava e-market, an online market place on the cassava matters website for cassava and cassava-related commodities, and an interactive voice recording (IVR) service powered by Viamo, where farmers simply dial 3-2-1 on Airtel network for cassava cultivation tips.

Others are video clips of the recommendations which extension agents are currently using in rural areas with the aid of battery-powered mobile projectors given to them by the project and radio programmes about cassava farming currently being aired in English, Yoruba and Tiv languages on some of the most popular radio stations in Benue and Oyo States.

He stressed that now that economies and food systems were being threatened by COVID-19 challenges, “these digital tools for scaling the six steps can help us navigate through the challenges of COVID-19 since restrictions to free movement and human to human contact can be by-passed with the use of digital technology.”
