Annual Medic Evaluation On Eradu Sandplain Soil - 3 M Rows., Bradley Nutt, M. K. Laslett

Experimental Summaries - Plant Research

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.

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.

Effect Of Deep Ripping And Aphid Infestation On Pasture Production., Bradley Nutt, M. K. Laslett

Experimental Summaries - Plant Research

Trial 88EC18

Location: East Chapman Research Station.

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 …

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 …

Annual Medic Evaluation On Eradu Sandplain Soil - Plots, Bradley Nutt, M. K. Laslett

Experimental Summaries - Plant Research

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 …

Location: Avondale, New Norcia, Darkan, Cranbrook, Arthur River, Kellerberrin North Quairdading, Gabalong, Merredin, Badgebup and Pingrup.

Over 300 recent overseas introductions of murex medic were evaluated in rows at South Perth in 1988. Of these 15 selections were identified with acceptable spinniness that flower in 100 days or less. Four years ago there was only one selection flowering in under 110 days and that was spiny!

These selections will be evaluated in small plot trials in several country sites in 1989.

This programme aims to identify superior varieties to Zodiac which was released in 1988.
