Yield and yield components were measured on two spring wheat (Triticum aestivum L. em Thell) cultivars, Neepawa and Pitic 62, and a 1:1 mixture of the two sown at five rates of seeding in each of 2 yr. Lack of agreement between performance in pure and mixed stands was observed when, at the highest seeding rate, the mixture yielded higher in 1974 and lower in 1976 than either of the component cultivars grown in pure stand.
