Abstract

In three years of irrigated trials the average biomass dry matter production was over 10 t ha1. In the first cut the spring cereals under-seeded to winter cereals produced almost three times as much biomass as the winter cereal and Italian ryegrass monocultures. In second cut, the winter cereal and Italian ryegrass monocultures produced three times more biomass than the underseeded spring cereals showing that the spring cereals caused a significant suppression of the under-seeded crops. There were no significant differences in the biomass yield of the monocultures of winter cereals, perennial cereal rye and Italian ryegrass. Winter survival data indicated that winter rye and perennial cereal rye survived well under irrigation and that winter triticale and Italian ryegrass did not so choice of winter crop may be influenced as to whether a producer wanted to have some early spring grazing or not. Protein content of the spring cereals averaged 14% compared to over 20% in the winter cereals and Italian ryegrass.
