| Abstract/Contents: | "Three types of ryegrass (Lolium spp.) have recently received interest as forage or seed crops in Western Canada. These are: Westerwold (L. multiflorum), which is an annual species; Italian (also L. multiflorum) which is a short-lived perennial in Europe, but generally does not survive our winter conditions; and perennial (L. perenne which is a short-lived perennial in Canada. Our research tested a range of cultivars of these species at Melfort, SK and Outlook, SK (irrigated) for forage and seed production and tested various management practices with the goal of maximizing seed production. Westerwold ryegrass seed yields varied from 400 to 1150 kg ha ā»1 in 1996 and 97, however; nonuniform maturity of tillers was a problem in the timing of harvest. This type also produced high forage yields following a seed crop, or when planted specifically for forage purposes. Italian ryegrass (which heads in the year after seeding) winterkilled almost 100% at both locations, thus seed production was not possible. When seeded as an annual forage crop, Italian ryegrass produced high yields of forage in the late summer and fall. For 1996 seedlings of perennial ryegrass, all cultivars were completely winterkilled at Melfort, but survival was generally good at Outlook, seed yields ranging from 100 to 600 kg ha ā»1 in 1997. For 1997 seedlings at both locations, most cultivars were severely winter damaged, thus no yields were taken in 1998. Late summer seedlings (15 August) produced higher seed yields than spring seedlings at Outlook, but late seedings frequently did not establish well at Melfort due to lack of soil moisture. For spring seeded trials, perennial ryegrass seeded under a companion crop survived the winter better than when seeded pure. These preliminary results indicate Westerwold ryegrass has a potential as either a seed or forage crop in western Canada; Italian ryegrass produces high yields of forage; and perennial ryegrass produced inconsistent results as a seed crop due to winter damage. Under irrigation, perennial ryegrass survival is enhanced by seeding in late summer, while for rainfed conditions, spring seedlings under companion crops gave the best survival." |
