1975 Weed Control In Lupin Investigations, J M. Allen

Experimental Summaries - Plant Research

1. The results with pre emergence herbicides confirm previous recommendations of simazine 1.25 kg/ha on heavy soil and diuron 1.25 kg/ha on light soils with the following modification. a) Simazine rates need to be increased to 3 kg/ha on very early (April) sovm crops in southern areas. b) Simazine has not damaged lupins in southern areas and where ryegrass is a major problem on sandy soils (i.e. Esperance) it is likely to give better responses than diuron. 2. As suspected in previous years simazine can by way of effective weed control produce a marked lupin vegetative response without any increase …

1975 South West Sub.Clover Root Rot - 1975 Cultivation Experiments, M J. Barbetti, G C. Macnish

Experimental Summaries - Plant Research

Trials were established in 1975 in the South West of WA to investigate the effect of time of cultivation, and nitrogen application, upon the incidence and severity of both tap and lateral root rot subterranean clover. Nitrogen application had little in the way of consistent effects. Cultivation reduced the levels of both tap and lateral root rot in many instances. These effects were most obvious and consistent at about the end of May. Cultivation just prior to or just after the break of season were the best cultivation treatments. Cultivation does appear to show some promise as a means of …

1975 Drought Responses Of Wheat Cultivars - Environment Responses Of Subterranean Clover., R N. Weir

Experimental Summaries - Plant Research

Environment responses of subterranean clover. Aim - To clarify the responses of four cultivars to temperature, vernalisation and photoperiod. Method - Dinninup, Midland B, Geraldton and Blackwood sub clover was grown in phytotron cabinets under 14 hour and 10 hour photoperiods and temperatures 10°c day/5°c night, l5/l0°c, 20/l5°C, 25/20°c. A seed vernalisation treatment of 6 weeks refrigeration of swelled seed was included. Dissections were made to observe first floral initiation and first flower production was noted. Conclusions - Higher temperatures either had no effect or delayed floral initiation, but accelerated flower development greatly from initiation to anthesis. Photoperiod and vernalisation …

Pasture Species Investigations - Wheat Belt (May, 1975), N. R. Mckeown

Experimental Summaries - Plant Research

Results from trials comparing the growth and persistence of a number of annual pasture legumes are presented in this report. Rainfall conditions during the year are described briefly and a table of annual and growing season rainfall at relevant centres is appended. The experiments are grouped as follows according to average annual rainfall:- Zone A - Average annual rainfall > 400 mm Zone B - Average annual rainfall 345 - 400 mm Zone C - Average annual rainfall < 345 mm and then, further, on soil type. District Rainfall, 1974. 71LG16,, 72LG3, 74KA3, 70OTS2, 72TS5, 70NA3, 71TS22, 74NO3, 70ME4. The early break, with good rainfall continuing through most of the growing season, provided optimal conditions for most wheat belt trials. These conditions were in direct contrast to the dry years of the late 1960's and early 1970's. In 1974, legume growth on droughty deep sands should have been at its best. Serradella responded at Kukerin in direct relationship with earlier heavy dressings of potash. West of Three Springs, serradella and Tornafield medic stayed a little ahead of Harbinger medic and well ahead of Daliak sub. clover and rose clover. On deep sands at Marchagee and Arrino, subterranean clover was the only species worth considering. The failure of Eragrostis curvula to persist through the dry 1973-74 summer after good germination in late winter, indicates a need for more work on the establishment of this grass on deep sands. The low yields of dry matter at Tincurrin do not offer much incentive for such work, but Eragrostis, lupins and serradella probably give the best chance of pasturing the grossly infertile, erodable sands. Under favourable conditions, Geraldton sub. clover continued to show its versatility and aggressiveness. On an alkaline loamy sand at Lake King, waterlogged for periods during the winter, Dwalganup, Geraldton and Northam A produced more dry matter than a wide range of other pasture legumes. At Walgoolan, Geraldton maintained better than 503 content in mixtures with other sub. clover cultivars sown in 1970, while in a trial at Marchagee there was evidence of gradual, aggressive regeneration of Geraldton from a sparse pasture sown before the trial. Only two new legume species trials were planted in 1974, and these were not successful. Trial 74KA3, east of Katanning, demonstrated the need for timely planting. Had seed been available on time, the trial would have been planted before the onset of heavy rains and would have given better results. The failure of Tornafield and Harbinger on 74N03 should not weight the record unduly against these medics; :they have never excelled on clay loams, and they were sorely harassed by redlegged earthmite. The medics will not be replanted, but Northam A and Geraldton will be observed in 1975. :

Pasture Deterioration - High Rainfall Areas, D J. Gillespie

Experimental Summaries - Plant Research

a. Pasture deterioration - High rainfall areas - A farm at Karridale (near Augusta) exhibiting "classic" pasture deterioration symptoms was closely monitored throughout 1974. This farm has paddocks ranging from relatively newly sown pastures with a high clover percentage, few weeds and high dry matter production (resown 1973 and 1974), through to extremely poor pastures with as little as 3 % clover and a weed component of over 80% (resown 1970 and 1971)... b. Midland B competition studies (69Mt19) -This grazing trial was sown in 1969 to plots of pure Midland B, pure Woogenellup and to three mixtures of the …

Weed Trials 1974 Summary - Annual Ryegrass Control - Wild Oats - Cereal Tolerance To 2,4-D - Annual Ryegrass Toxicity, G. A. Pearce

Experimental Summaries - Plant Research

A herbicide trial and demonstration was commenced in 1973 and the treatment repeated in 1974. the objective was to control the annual ryegrass which was the dominant species and allow the scattered plants of sub clover to re-establish a clover dominant pasture. (See table) Despite the high reduction of seed stalks formed on some treatments in 1973 the ryegrass was only reduced by 50 per cent on the best treatment in 1974, The reduction in seed production in 1974 will no doubt further reduce the density of ryegrass in 1975 but eradication is unlikely. The value of burning in destroying …
