The effect of residue management on black bean (Phaseolus vulgaris L.) height, maturity, and yield was studied at two sites in Saskatchewan in 1999. Treatments were spring cultivated, mowed or left as standing stubble prior to seeding. CDC Nighthawk was damaged by fall frost. Tillage reduced emergence in cultivated treatments compared to no-till, possibly by causing compaction, reducing macroporosity and creating conditions suitable for root diseases. Plant density differences largely determined yield, biomass at physiological maturity, and pod clearance. Yields were 682 kg/ha, 838 kg/ha, 880 kg/ha for cultivated, mowed and stubble respectively. Plant height was not significantly affected by tillage. Bean pod clearance under conventional tillage was 5% higher than under no-till, regardless of stubble height, possibly because of the lower plant density in cultivated treatments. Differences among treatments for internode length were not statistically significant. Residue management had no effect on maturity of either black bean cultivar studied.
