Effect of cutting interval and winter dormancy on yield, persistence, nitrogen concentration, and root reserves of irrigated lucerne in the Queensland subtropics

Autor: KF Lowe, D Gramshaw, DL Lloyd

Publikováno v: Australian Journal of Experimental Agriculture. 33:847

The use of fixed interval or growth stage (crown bud elongation) cutting management for lucerne was studied for cultivars with dormancy characteristics ranging from highly winter-active to winter-dormant. Fixed cutting intervals ranged from 3 to 8 we

Performance of North American and Australian lucernes in the Queensland subtropics. 1. Field reaction to important root and crown diseases

Autor: D Gramshaw, PW Langdon, KF Lowe, DL Lloyd

Publikováno v: Australian Journal of Experimental Agriculture. 25:76

Twenty-three lucernes from North America and five Australian lines were assessed for their sensitivity to root rot (Phytophthora megasperma f. sp. medicaginis), anthracnose/ crown rot (Colletotrichum trifolii) and root canker (Rhizoctonia solani). Pl

Survival of annual ryegrass (Lolium rigidum Gaud.) seed in a Mediterranean type environment. II.* Effects of short-term burial on persistence of viable seed

Autor: WR Stern, D Gramshaw

Publikováno v: Australian Journal of Agricultural Research. 28:93

Two seed components, dark dormant and non-dark dormant, were identified in experiments in which germination and survival of seeds buried in soil were examined. These comprised c. 10–20% and 80–90% of the seed population respectively. About 12% of

Classification of a collection of the legume Alysicarpus using morphological and preliminary agronomic attributes

Autor: F. W. Muller, R. J. Williams, W. A. T. Harding, D. Gramshaw, B. C. Pengelly

Publikováno v: Australian Journal of Agricultural Research. 38:355

A collection of 121 accessions of the legume genus Alysicnrpus was grown out and classified using morphological and agronomic attributes. Nineteen morphological-agronomic groups were identified and matched, where possible, to previous taxonomic class

Performance of North American and Australian lucernes in the Queensland subtropics. 3. Yield, plant survival and aphid populations in raingrown stands

Autor: D Gramshaw, TB Hilder, DL Lloyd, DH Ludke, JW Turner

Publikováno v: Australian Journal of Experimental Agriculture. 25:91

Twenty-three North American and up to five Australian lucerne lines were evaluated for dry matter yield, plant persistence and aphid resistance at three sites under raingrown conditions in southern Queensland. The experiment at Toowoomba was conducte

Performance of grazed creeping-rooted lucernes on two soils in central Queensland

Autor: D Gramshaw, DH Ludke, HG Bishop

Publikováno v: Australian Journal of Experimental Agriculture. 22:177

The creeping-rooted lucernes (Medicago falcata x M. sativa), cv. Walkabout and breeder's line ECRS 1, were compared with M. sativa cvv. Hunter River and Siro Peruvian for persistence and production under dryland conditions on alluvial and solonetz so

Effect of sowing rate, grass competition and cutting frequency on persistence and productivity of two lucerne (Medicago sativa) cultivars at Biloela, Queensland

Autor: D Gramshaw, HG Bishop

Publikováno v: Australian Journal of Experimental Agriculture. 17:105

Persistence and production of lucerne (Medicago sativa) cvv. Hunter River and Siro Peruvian were studied on alluvial soil under raingrown conditions in a factorial experiment examining effects of lucerne sowing rates (1.1 and 4.4 kg ha-1), competitio

Survival of annual ryegrass (Lolium rigidum Gaud.) in a Mediterranean type environment. 1. Effect of summer grazing by sheep on seed numbers and seed germination in autumn

Autor: WR Stern, D Gramshaw

Publikováno v: Australian Journal of Agricultural Research. 28:81

Annual ryegrass–subterranean clover pastures that produced about 5000 kg total dry weight per hectare and 23,500 ryegrass seed per sq metre in spring were grazed by sheep at different stocking rates during summer. Intensive stocking equivalent to a
