Three promising bread wheat (Triticum aestivum) genotypes were compared with two released check varieties by farmers' research groups using both researcher and farmer-selected crop management practices. Agronomic and economic data and farmers' assessment criteria were collected during the conduct of the trials on four host farmers' fields during 1999. The statistical analysis across the four sites indicated that there were significant grain yield differences due to genotype and crop management levelhowever, interactions between genotype by site and genotype by management level were nonsignificant. Mean grain yields for the farmer- and researcher-managed plots were 1802 and 2148 kg/ha, respectively. One advanced line, HAR.2258, was high yielding and preferred by farmers on the basis of its crop stand, spike size, disease resistance, maturity class and crop uniformity. HAR-2258 and the check variety Abolla were both preferred by farmers for their quality in making staple food products. The improved crop management package for bread wheat was highly profitable for peasant farmers in N. W. Ethiopia: the researcher-managed production package increased wheat grain yields by an average of 19% across the four locations, and exhibited a marginal rate of return of210% in comparison with the farmer-managed production practices.
