Yields of direct-seeded and spring-cultivated narrow-row dry bean were comparable in two years in Saskatchewan. Either treatment appears to be an acceptable residue management practice for dry bean in this area. A dryland, narrow-row production system for dry bean (Phaseolus vulgaris L.) is being refined for the black soil zone of Saskatchewan. The effect of residue management on two cultivars of dry bean was studied at two locations in Saskatchewan in 1999 and 2000. Plots were spring cultivated (C), mowed (M) or left as standing stubble (S) prior to seeding. The C treatment had significantly lower plant densities than M or S in 1999 at the Rosthern location. Treatment differences for density in the 2000 season were not significant. There was no significant yield effect for residue management when differences in emergence were accounted for by covariate analysis. However, there was a significant interaction of residue treatment and cultivar in 1999 at the Rosthern location. For the 2000 season, average yields over both cultivars and locations were 941, 776, and 888 kg ha-1 for C, M and S respectively and all differed significantly from each other. Spring cultivation and direct-seeding both appear to be acceptable residue management practices for dry bean. The heavier surface residue conditions of the mowed treatment seemed to be generally detrimental to yields.
