Tailoring and adaptation in N2Africa demonstration trials

Submitted by charlotte.schilt on

One of N2Africa's objectives is to "tailor and adapt legume technologies to close yield gaps and expand the area of legume production within the farm" (Objective 4). Sub-objectives are to develop variety * inoculant * nutrient management recommendations for the target legumes and areas (Objective 4.1), and to develop best-fit recommendations (Objective 5.5). Each season, in diagnostic and demonstration trials, the effectiveness of varieties, inputs and management practices has been assessed, leading to the development of such recommendations. In other words: technologies were tailored and adapted to make them more suitable for specific legumes, areas or groups of farmers. To report on these objectives, we would like to capture the "learning pathways" that have led to changes in the design of demonstration trials and the development of best-fit recommendations.

This report provides an overview of changes that have occurred on trials in terms of variety selection, input choice and other practices. These changes and their reasons and initiators are listed in tables per crop for five core countries: Ghana, Nigeria, Ethiopia, Tanzania and Uganda. The report only comprises the changes that have occurred, not the full overview of technologies that are being tested and demonstrated by N2Africa.

Information about the learning pathways were collected via an ODK survey with country coordinators and field research officers Samuel Adjei-Nsiah and Arnold Sylvester Amppiah (Ghana), Endalkachew  Wolde-Meskel and Birhan Abdulkadir (Ethiopia), Bassey Ukem (Nigeria), Abubakar Mohammed (Nigeria), Sheu Muhammad Dandago (Nigeria), Abubakari Mzanda (Tanzania) and Anthony Epel (Uganda). They described the changes that had occurred in demonstration trials since the beginning of N2Africa Phase II in 2014, and the stakeholders who initiated the actions.
