Tactical Nitrogen Decisions For Wheat (And Nitrogen Sources Rates And Times On Wheat), J. W. Bowden, R. J. Lunt

Experimental Summaries - Plant Research

Trial 89MO49

Location: Tenderloin, Brand Highway, Regan's Ford.

History:

1987 Aroona wheat with 70 kg DAP and 3 kg CuSO4 at seeding followed by 60 urea at 3WAS and another 40 urea at 6WAS. Yield was about 1.7 to 1.8 t/ha;
1988 Gungurru lupins with 120 kg super and manganese/ha yielded 1.9 t/ha. 350-400 ml Roundup/ha and one cultivation prior to seeding.

Rhizoctonia Control In Potatoes And Potato Resistance To Powdery Scab., R M. Floyd

Experimental Summaries - Plant Research

Trials : 88BY26, 88PE34, 88MD35

Control of Rhizoctonia solani infection of potato stems and daughter tubers was demonstrated by preplanting applications of tolclofos-methyl (RIZOLEX TM) to either cut or round seed tubers. Yield of tubers from cut seed treated with Rizolex was increased over that of cut seed cured before planting bu not when seed was cut and planted the same day. Crops grown from round seed treated with Rizolex yielded higher than from untreated round seed.

Surface sterilization of seed tubers with Sodium hypochlorite was effective in reducing stem damage but not in reducing daughter tuber sclerotes. This indicates …

New Block Badgingarra Rs Late Time Of Seeding., J. W. Bowden, R. J. Lunt

Experimental Summaries - Plant Research

Trial 89BA33,

Location: Badgingarra

Based on a 1.5 t/ha potential yield, the strategic treatment was planned to be 120 kg urea/ha 4WAS. However, the crop was poorly established and so NH4NO3 was used in the hope of getting better tillering than would be possible with the slower release urea source. Gambling on equal dollars to urea for 2/3 N, but believe that twice as effective.

DAP was used to place nitrogen with the seed in case there was no rain of significance after seeding. This nitrogen (only 5 kg/ha) was probably lost with the rains of 20-28/7/89 (50 mm). Urea …

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.

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 …

Trial 86KA71

Location: Private farm 'Monalta' - south-east of Katanning.

As outlined by S. Flecker in the 1987 summary for this trial, the expected result of the research is that the feeding value of burr medic pastures will be greater than the feeding value of sub. clover and barrel medic pasture, particularly over the dry summer/autumn period.

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.

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 …

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 …

Evaluation Of New Pasture Legume Species In Terms Of Summer Feeding Value And Effects On Wool Production., S E. Flecker, C W. Thorn, J. B. Rowe, Tess Casson

Experimental Summaries - Plant Research

86KA71, Pasture legumes improve the feeding value of summer pastures in a mediterranean-type environment by maintaining the protein intake of grazing animals over the dry summer period, much of which comes from the ingestion of legume burr (A.D. Wilson and N.L. Hindley, 1968). Some of the most important species of pasture legumes to have been released commercially are Trifolium subterraneum (sub.clover), Medicago truncatula (barrel medic) and Medicago polymorpha (burr medic) (D.B. Purser, G.B. Taylor and W.J. Collins, 1987). What little information is available on the feeding value of these species suggests that barrel medic pod (H. Brownlee, 1973) and dry …

Trial 65SG5. Location - Paddock H5 on Salmon Gum Research Station

Cleared in 1962, then cropped until the start of the trial in 1968. Two of the four blocks were sown to Cyprus Barrel medic which is topdressed with superphosphate. The other two blocks regenerate volunteer pasture which is not topdressed. In 1984 all pasture plots were sown to SERENA medic. This grew exceptionally well in 1984 and set a lot of seed. In 1987 field peas were introduced into 4 reps of an existing medic: crop rotation.

The Effect Of Soil Acidity On Barley, P J. Dolling, T. D. Haines

Experimental Summaries - Plant Research

Three liming experiments were established to confirm previous estimates of the critical soil acidity level for barley. Two experiments studying the effect of depth of incorporation on the effectiveness of lime, established in 1986, were continued in 1987.
The results from the three liming experiments established this year supported the conclusion that barley is affected by soil acidity at pH's around 4.2 and 4.3 (CaC1₂) and that depth of this acid layer is important.
Significant lime responses were obtained at the Katanning depth of lime incorporation site but conclusions can not be made because of possible mixing of …
