Description
The objective of the study was to extend the grazing season into the fall using crop-combinations of spring-planted spring and winter cereals. Treatments established at Lacombe, Alberta, Canada were spring oat (Avena sativa L.) and barley (Hordeum vulgare L.) monocrops (SMC), spring-planted winter wheat (Tritcum aestivum L.) and winter triticale (X Triticosecale Wittmack) monocrops (WMC), spring and winter cereal binary mixtures seeded together in the spring (MX) and the winter cereal seeded after the first clipping of the spring cereal (double crop-DC). Clippings were carried out at 4 to 6 wk intervals after the initial cut (Boot and Late Milk Stage). MX produced more total yield than other systems when cut initially at the Late Milk stage ( 92% of SMC at initial cut and 65% of WMC for regrowth). MX was superior to DC and SMC for regrowth yield, but not WMC. Treatments containing winter triticale were superior to those containing winter wheat for fall regrowth. Cropping systems like MX have the potential to economically extend the grazing season in the parkland of the Canadian prairies.
