1975 Nitrogenous Fertilisers For Cereals - Trials With Wheat, Oats And Barley, M. G. Mason
1975 Nitrogenous Fertilisers For Cereals - Trials With Wheat, Oats And Barley, M. G. Mason
Experimental Summaries - Plant Research
Rates of nitrogen on wheat - soil test - Fifty-one sites were selected and soil sampled during February- March. All these proposed trials consisted of four replications and these reps were soil sampled separately. In each rep. 20 samples were taken to 10cm depth with pogo stick samplers. In addition, from three holes at random across each trial bulk samples were obtained from the 0-15, 15-30 and 30-45 cm soil intervals These soil samples were air dried (if not already dry) and sieved to remove > 2 mm fraction (gravel). Portions of these < 2mm fractions from the 0-10cm samples were sent to the Government Chemical Laboratories and to C.S.B.P. & Farmers Ltd. At C.S.B.P. analyses were carried out to determine P and K content and the C.S.B.P. soil nitrogen test was also carried out on them. This measures nitrate content before and after incubation with moist soil at 32c for seven days. A measurement was also made after 14 days. At Government Chemical Laboratories analyses were to be carried for Organic carbon and for a number of nitrogen fractions, including Total Nitrogen, MH4 + NO3 Nitrogen and several incubation techniques. These were also to be determined on the profile samples, which were also to be subject to the following analyses: a) Mechanical Analysis b) pH (in water) c) Cation Exchange Capacity d) Moisture Holding Capacity All of these trials were planted except for one at Jerramungup, where the marker pegs were ploughed out by the farmer. Vegetative cuts were then taken during the August - September period on 46 of the remaining 50 sites. Three of the other four sites were abandoned because of severe waterlogging (Neridup), extreme weediness (Nugadong) or due to poor plant survival (possibly due to webworm) combined with weeds (Mallalying). The trial at Wannamal was sown to oats, by the farmer. The nitrogen treatments were still applied and the trial was retained but not sampled for dry matter production. These samples were to be analysed for nitrogen content. Dry matter production and grain yields are set out in the following tables. 61M11, 75A1. 75A2, 75A3, 75AL1, 75AL2, 75BA2, 75BA3, 75BR1, 75BR2, 75C1, 75C2, 75C3, 75E2, 75E3, 75ES1, 75ES2, 75ES4, 75GE1, 75GE2, 75GE3, 75JE1, 5JE2, 75KA1, 75KA2, 75LG1, 75LG2, 75LG3, 75M2, 75M3,75M4, 75ME1, 75ME2, 75ME3, 75MO1, 75MO2, 75MO4, 75MT2, 75MT3, 75N1, 75N2, 75N3, 75NA1, 75NA3. 75NA4, 75NO2, 75NO3, 75SG1, 75SG2, 75TS2, 75TS3, 75TS4, 75WH4, 75WH5, 75WH6, 75WH7.

1. From September 1971 to late August 1974 there was a mean reduction of legume content in the medic pastures from 40 per cent to 22.0 per cent but the reduction at 7.4 sh/ha was to 31 per cent. The drop in woolly clover content on the volunteer pastures was closely similar. 2. In 1972, at 7.4 sheep/ha a difference in body weight of 7-9 kg rapidly developed in favour of sheep grazing barrel medic compared with sheep on volunteer pasture. This difference was maintained consistently throughout the trial. At lower stocking rates the differences were smaller and less consistent. …

Evaluation Of The Systemic Nematicide Phenamiphos To Control The Nematode Anguina Sp In Toxic Ryegrass Pasture, B A. Stynes
Experimental Summaries - Plant Research
Field trials done in 1974 showed that phenamiphos could be used to control Anguina sp. and suggested that low rates may be effective with critical timing of applications. These possibilities were investigated in 1975. Locality - Katanning - F. Quartermaine and c. Butterworth. Gnowangerup - J. Griffith. Tables 1 and 2 show the absolute levels of nematodes in ryegrass seed and the density of nematodes per unit area of pasture after treatment with phenamiphos. All rates of nematicide reduced the level and density of nematodes; the highest rate being slightly more effective. The spray schedule including sprays in July and …

Summary Of 1974 Weed Control In Lupin Evaluations, J. G. Allen
Experimental Summaries - Plant Research
Lupin Trials 1974 1. Herbicides x Depth of Seeding - There is no evidence of a herbicide x depth of seeding interaction in lupin plant numbers, at either Broomehill or Eradu. The lupin plants on the shallow sown plots were reported to be more effected by herbicides than on the deeper sown plots at Eradu. It is suggested that shallow seeding may be a factor in predisposing lupin crops to simazine damage particularly on sandy soils, however it has not been possible to demonstrate such on effect. 2. Herbicides x Time of Seeding - At two sites (Myrup, Namban) there …

Experimental Summaries - Plant Research
Sclerotinia stem rot, a fungal disease, is becoming increasingly important. This disease can attack the stem at any point from the stem base to the first laterals. Lodging can result if the canker is severe enough. Superficial cankers can disrupt sap flow resulting in poorly filled pods. The fungicide Benlate is used overseas to control Sclerotinia in bean plantings, Accordingly, a fungicide trial was planned to estimate yield losses resulting from Sclerotinia infection. A secondary aim was to examine any yield response which could be attributed to reported growth promoting properties of benomyl - 75MT33. Brown spot of lupins - …

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 …

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 …

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 …

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. :

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.
