Abstract
Impact evidence constitute a strong foundation for transparency and accountability in agricultural research. The robust evidence generated by impact evaluations is increasingly serving as a foundation for greater accountability, innovation, and learning. This context, in fact forms the rationale for the present study and the project is proposed with the aim of promotion and impact evaluation of ICAR-IIWBR wheat variety (DBW 222) at farmers’ field.
