Abstract
The effect of row spacings on yields of HY320 and Neepawa spring wheats and Norstar and Norwin winter wheats was investigated at several locations in central and northern Saskatchewan. These results, although preliminary, indicated that yields increased as row spacings decreased. The effect of row spacing appeared to be greatest where yields were highest although significant row spacing effects were also noted at those sites where yields were lower. Data from a limited number of sites where counts of head numbers per m^2 were made indicated that much of the difference in yields between row spacings could be accounted for by increased numbers of heads being produced at narrower spacings.
