The physiological response to cutting in Italian ryegrass

Grass and Forage Science, 1977
AbstractThe kinetics of decline in net photosynthesis and transpiration after cutting was followed in a batch of Lolium multiflorum leaves at light saturation in an assimilation chamber where air temperature, leaf temperature, carbon dioxide concentration and water vapour concentration were controlled.

THE CRUDE‐PROTEIN CONTENT OF ITALIAN RYEGRASS

Grass and Forage Science, 1961
The effects of variety, date of cutting flush growth and level of nitrogenous manuring on the crude‐protein content of Italian ryegrass were studied on plots cut five times in 1958.Raising the level of nitrogenous fertilizer from 174 lb. to 348 1b. N/acre reduced the percentage of dry matter from 0·5 to 2·0 and increased the percentage of crude protein

Italian ryegrass as a perennial fodder crop

Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1976
Italian ryegrass (Lolium multiflorum Lam.) may be re-established from seedfall if the appropriate management practices are applied, and may thus function as a perennial fodder crop. Annual seedbed preparation and seeding are eliminated in this way.Keywords: botany; fodder; grasses; italian ryegrass; lolium multiflorum; management; ryegrass;

Chlorotic Streaking in Italian Ryegrass

Plant Pathology, 1974
SUMMARY A virus apparently indistinguishable from the ryegrass.chlorotic streak virus in New Zealand has been found in Britain where it appears to be similar to, if not identical with, isolates of barley yellow dwarf virus transmitted specifically by Rhopalosiphum padi .

Responses of Italian ryegrass to phosphorus on highly‐weathered soils

Journal of the Grassland Society of Southern Africa, 1991
Italian ryegrass (Lolium multiflorum cv. Midmar) responses to fertilizer P were studied in field experiments under irrigation on highly-weathered ferrallitic soils at two localities in Natal. Each experiment was conducted over two seasons (1985 and 1986), the pasture being re-established after the first season.

Hybrids between tetraploid Italian and perennial ryegrass

Theoretical and Applied Genetics, 1977
Hybridization frequency was investigated between tetraploid perennial and Italian ryegrass (Lolium perenne X multiflorum) without emasculation by using genetic markers. The Italian phenotypes, fluorescentroots and awned florets, were dominant. About 82% of the plants in perennial X Italian and nearly 93 % of the plants in the reciprocal crosses were ...

Identification of companion small grains for midmar Italian ryegrass

Journal of the Grassland Society of Southern Africa, 1988
In a preliminary investigation four small grain species, oats (Avena sativa) rye (Secalae cereale), wheat (Triticum aestivum) and triticale (Triticum x secalae) were planted alone and in combination with Lolium multiflorum cv Midmar under irrigation. The dry matter (DM) yield of Midmar was also compared to that of four other annual ryegrass cultivars ...

Interaction between BSM-contaminated soils and Italian ryegrass

Journal of Environmental Science and Health, Part B, 2012
The interaction among the bensulfuron-methyl, growth of Italian ryegrass, and soil chemical/biochemical/microbiological parameters was investigated in a microcosm experiment. The bensulfuron-methyl added to the soil can be rapidly degraded by certain fungi and actinomycetes present in the original paddy rice soil.

Identification of companion legumes for midmar Italian ryegrass

Journal of the Grassland Society of Southern Africa, 1987
In a preliminary investigation seven legumes were planted alone and in combination with Lolium multiflorum cv. Midmar. The pure stands of legumes were harvested at either four, five of six week cutting intervals, while the pure stands of Lolium multiflorum and the ryegrass/legume mixtures received in addition to the cutting treatments 0, 200 of 400 kg ...

POST control of Italian ryegrass in hazelnut orchards

Weed Technology, 2021
AbstractItalian ryegrass has become a problematic weed in hazelnut orchards of Oregon because of the presence of herbicide-resistant populations. Resistant and multiple-resistant Italian ryegrass populations are now the predominant biotypes in Oregon; there is no information on which herbicides effectively control Italian ryegrass in hazelnut orchards.
