Abstract
North-south row directions were compared with east-west, using two varieties of barley and two of oats. In one experiment continued over 3 years, the grain was sown with nursery plot equipment in rows 30 cm apart. North-south rows outyielded east-west by 9% in barley and by 4% in oats.Two additional experiments involving row widths of 15 and 30 cm were sown with a grain drill. Row direction did not consistently affect the yield of barley in either spacing, but there was a tendency for yields to be higher in 15-cm than in 30-cm spacings. North-south rows outyielded east-west rows in oats, but differences were significant only in the 30-cm spacing. Row spacing did not affect yield of oats.
