Resource management technical reports

Legume herbage mass was maximized after two or three years application of 50 kg/ha double superphosphate for both Verano and Fitzroy on Red earth soils and for Fitzroy on Yellow lateritic soils. There was increased production of Verano up to the maximum fertilizer level. Both varieties responded in the second year to residual P following application in the first year but there were no responses in subsequent years.

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 …

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 …

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.
