ryegrass

highly productive pasture grasses including Wimmera or annual ryegrass (Lolium rigidum), Italian ryegrass (L. multiflorum) and perennial ryegrass (L. perenne).

ryegrass staggers
ruminants and horses grazing pastures dominated by L. perenne (perennial ryegrass) may be affected with a severe incoordination which appears with forced exercise but disappears if the animals are left to their own devices. Caused by tremorgen lolitrems from the endophyte Neotyphodium (Acremonium) lolii which infests the grass.

Field studies were conducted at the Louisiana State University Agricultural Center Rosepine Research Station in Rosepine, Louisiana (30[degrees] 95' N, 93[degrees] 28' W) to investigate the effects of maturity and bale location in in-line wrapped tubes of annual ryegrass round bale silage.
The interactions that occurred between harvest stage and pre and post-harvest characteristics (storage) were significant for bale weight, WSC, ADIN, ADF, and NDF, indicating that differences in nutritive value and fermentation of annual ryegrass baleage was mostly determined by forage condition at harvest.
Nungarin, capeweed, and annual ryegrass were grown, in a glasshouse, in 5-L pots containing sand.

In some cases, growers are now facing higher costs for weed and pest control, as evidenced by this summer's rampant vole population, which reduced annual ryegrass yields by more than 50 percent.

Root mass at 10-20 cm depth was greatest for herb ley and least for clover and direct drilled annual ryegrass.
After 3 years of the experiment, at 0-10 cm depth the annual cropped treatments (barley and lupin) had the smallest and the direct drilled annual ryegrass treatment had the greatest soil organic C (Table 4).
