Yield of spring wheat and field pea seeded into standing and cultivated canola stubble on the semiarid Canadian prairie

Cutforth, H. 2013. Yield of spring wheat and field pea seeded into standing and cultivated canola stubble on the semiarid Canadian prairie. Can. J. Plant Sci. 93: 287–289. Previous research in the semiarid prairie showed that crop yields increased as the height of standing cereal stubble increased to ≥45 cm. A 3-yr (2008–2010) study was conducted at Swift Current, SK, to determine how seeding field pea and spring wheat into cultivated and tall (≥45 cm high) canola stubble affected crop yield. Similar to cereal stubble, crop yield and water use efficiency were significantly greater for crops grown in the tall standing canola stubble compared to the cultivated stubble. Water use by each crop was independent of stubble management.
