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 …

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 …

Pasture Species Evaluation On Acid Wodjil Soil - Machine Sown Plots., Bradley Nutt

Experimental Summaries - Plant Research

Trial 89TS38

Location: East Latham

The very low seed yields are a reflection of the dry winter conditions experienced in 1989. The Rose (T. hirtum) and Cupped (T. cherli) clovers appear to be a more promising option for this difficult soil type compared to other species. Paros yellow serradella performed well considering the trial site is located in a very dry area. The burr medics would not be an option on these acidic soil types because of nodulation failure; which should become evident in the regenerating swards.

Legume Species Mixtures., C. M. Saunders

Current recommendations for pasture species in the medium rainfall zone has not included species mixtures for paddocks with varying soil types. These trials (three in total) are designed to test the hypothesis that legume species mixtures are more productive and persistent in the long term than monocultures, across three soil types and three different cropping/pasture rotations (continuous pasture, 1 year pasture : 1 year crop rotation, 2 years pasture : 1 year crop rotation).

Lupin Variety Tolerance To Herbicides, D Bowran, R Watson

Experimental Summaries - Plant Research

Trial 88EC31

This site received a basal treatment of 1.5 L of simazine/ha prior to seeding. Due to a heavy stubble load lupin seed was dropped onto the surface and lightly incorporated.

High rates of Simazine were better tolerated by Gungurru 75A/260 and CE2/435. The highest rate of Brodal reduced yields in all varieties except Gungurru.

Trial 88EB27

This site was severely infested with aphids and bean mosaic virus such that the varieties Illyarrie and Danja had up to 60% plant death by anthesis. Other varieties were affected but to a lesser extent.
