Abstract

In Uzbekistan, ICARDA partners with two major national institutions—SARI (Southern Research Institute of Agriculture, Karshi) and SRIRA (Scientific Research Institute of Rainfed Agriculture)—to sustainably close yield gaps in wheat and mungbean (after wheat) by promoting Good Agricultural Practices (GAP) as an integrated bundled solution (IBS) rather than single “standalone” interventions. This report summarizes a participatory scaling approach built on (i) on-farm demonstrations and (ii) farmer training/field seminars, implemented with SARI in Kashkadarya (Karshi region) and SRIRA in Jizzakh. The overarching goal is to close persistent yield gaps in wheat-based systems and diversify intensification options (e.g., mungbean after wheat) under increasing water constraints and climate variability. These demonstration and training events have benefited over 200,000 ha of wheat and mungbean, directly benefiting over 200 farmers and indirectly benefiting over 1,000 farmers, with over 25% yield increase.
