Hypothesis: The oat variety (Garry) is non-competitive with weeds; other varieties could be more competitive. Experiment: 3 traditional varieties (cultvars) and 3 modern culitvars were planted on each of 5 fields (3 reps at each site), and final crop and weed biomass determined. Observations: The three tradional cultivars, including Garry (then in use on the farm) and one of the three modern culitivars competed well with weeds; two of the three modern culitvars did not. Conclusion: The poor oat yields were not due to poor competitiveness with weeds.
