Insights into the costing of on-farm testing: A case study of maize tricot trials by Zambia Agricultural and Research Institute (ZARI)

This report summarizes the costing methods and key assumptions in the estimation of costing for the maize tricot trial under the Zambia Agricultural Research Institute (ZARI). It outlines the major expenditure components and shows how each contributes to total implementation costs. It highlights the major cost drivers and shows how deviations from the tricot steps affect efficiency. It also provides an overview of what the results mean for variety development and scaling of on-farm testing. Finally, the report offers recommendations to improve cost-efficiency and support institutional integration of decentralized on-farm testing.
