Seed Production And Hard Seededness Of Trifolium Subterraneum Subsp Brachycalycinum, Michael D A Bolland
Seed Production And Hard Seededness Of Trifolium Subterraneum Subsp Brachycalycinum, Michael D A Bolland
Technical Bulletins
Ungrazed swards of some subsp. brachycalycinum strains produced reasonable seed yields compared with subsp. subterraneum on the sandplain soils and annual Medicago species on the alkaline mallee soils. However, in swards which were grazed by sheep up to the start of flowering, subsp. brachycalycinum produced disappointing seed yields compared with subsp. subterraneum and annual Medicago species. On a sandy soil, prevention of burr burial compared with covering developing burrs with sand drastically reduce ation an inhibiting light factor operates to drastically reduce seed production.

Santiago Extends The Range Of Burr Medics, Clinton K. Revell, Michael Ewing
Journal of the Department of Agriculture, Western Australia, Series 4
The release of Santiago follows an extensive Department of Agriculture testing programme conducted primarily in the 325 to 425 mm rainfall zone. Santiago substantially outperformed both Serena and Circle Valley and was the best amongst the large number of non-commercial medic varieties tested. About 500J000 ha were sown to burr medic between 1983 and 1988 and the Department of Agriculture expects that the release of Santiago will result in additional new plantings from

Trial 88EC16
Location: East Chapman Research Station
Inoculated and lime pelleted seed was hand sown into 3m rows at 0.25 g/m. All the medics were inoculated with WSM 540 which may have been less effective with some of the M. littoralis and M. tornata varieties. The 1988 season was very good in terms of frequency and amount of rainfall which is reflected in the high seed yields compared to 1987.

The project aims to develop, by breeding and selection, better adapted and more productive low-oestrogen cultivars of subterranean clover for a range of environments in southern Australia. The programme is a collaborative one with the University of Western Australia and consists of two phases (i) early generation selection, which involves selecting varieties satisfying primary selection criteria; and (ii) field evaluation of advanced lines, which is conducted by the Departments of Agriculture in each State and co-ordinated by the Plant Breeder. The first phase is conducted …

In 1988 a research programme was initiated to help define the relationship between soil and plant contamination. Two main experiments were established 1) Pasture contamination in annual and perennial grazed swards. 2) Plant species contamination in a wider range of pasture and crops.

Trial 88EC17
Location: East Chapman Research Station.
The plots were hand sown at 2 g/m2 of inoculated and lime pelleted seed. The medics were inoculated with WSM540 which may have been ineffective on some of the M. littoralis and M. tornata varieties. The time taken to form ripe pods was monitored to gain some extra measure of maturity besides flowering time for comparing wide ranges of species. The ripening time involved was very similar over all the varieties, averaging out to 44 days after the flower opens. What appears to be a more important factor when considering maturity is the …

Half the trial site was cultivated to 30cm at the break of the season and the whole site was normally cultivated. Weeds were then sprayed with Roundup at 1 1/ha prior to seeding with an eight run cone seeder. The plots were kept weed free during the year by hand weeding. The root distribution was calculated from soil cores taken in 20 cm increments on 20 August. Aphid cortrol consisted of spraying every two weeks with Pirimor at 140 g/ha between July and October. Lorsban at 150 ml/ha was used for the last …

Improving Lupin Pod Setting And Yield, R J. Delane
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australia's lupin production has grown twenty-fold since 1977. Lupins are now a valuable seed, feed and rotation crop on light-textured neutral and acid soils throughout southern Australia. Nevertheless, both experimental and commercial yields have been variable over sites and seasons. A major cause has been excessive flower and pod abortion on the main stem. Farmers have often commented on well grown lupin crops which appear to carry few pods

The Use Of Permeability, Conductivity, Conductance And Resistance In The Description Of Water Movement In Soils And Plants, H Borg
Resource management technical reports
Permeability, conductivity, conductance and resistance are important parameters in the description of water movement in soils and plants. These terms are related, but not synonymous. Permeability is only a function of the flow pathgeometry of the medium, while conductivity also depends on the fluid involved. Conductance, in addition, takes the size of the medium into account. Resistance is simply the inverse ofconductance. By applying the definition of resistance, it isshown that Darcy's law and Ohm's law are equivalent. Conductance and resistance relate volume flow rate to a potential difference, but to relate volume flux (volume flowrate per unit area) to …
