Disease And Insect Resistance Screening Of The National Subterranean Clover Collection, D J. Gillespie, M J. Barbetti
Disease And Insect Resistance Screening Of The National Subterranean Clover Collection, D J. Gillespie, M J. Barbetti
Division of Plant Research : Technical Report Series
This project commenced in May 1981 primarily to identify sources of resistance to clover scorch (Kabatiella caulivora), root rots (Pythium, Fusarium and Rhizoctonia spp.), and bluegreen aphid (Acyrthospihon kondoi) in the National Subterranean Clover Collection. Screening for resistance to red legged earthmite (Halotydeus destructor) was initiated part way through the project. Since commencement approximately 5,250 introductions and crossbred clover shave been tested for resistance to clover scorch, 420 for resistance to rootrots, 690 for resistance to blue green aphid and 160 for resistance to redlegged earth mite (R.L.E.M.). A large number of clovers possessing resistance to clover scorch have been …

Factors Affecting Frost Damage To Wheat In Western Australia, S P. Loss
Division of Plant Research : Technical Report Series
It may at first seem strange that precious research funds are being channelled into a project concerned with frost damage in a country where high temperatures and moisture stress limit the growth of plants for a large portion of the year. But cereal crops are only grown in the temperate zones of the continent during winter and spring when they may be exposed to low diurnal temperatures. In many areas cold damage is irregular and rare,however it limits yields not only by causing actual damage but also by restricting the most effective period for flowering. For muck of the Australian …

The Esperance Rotation Trial, Effect Of Rotations On Crop Yields And Soil Fertility, I C. Rowland
Division of Plant Research : Technical Report Series
This report sets out and summarises data from the Esperance rotation trial.This long-term trial, situated on the Esperance Downs Research Station, looks at various aspects of rotations based on subterranean clover pasture with cereals or sweet lupins as a crop. Data included are yields of the crops both grain and dry matter at anthesis or mid-pod fill also nitrogen content at these two times; pasture production and composition in Spring; clover seed production; weed counts in the crop; soil measurements of total soil nitrogen,organic carbon, mineral nitrogen, pH and extractable potassium are done at thestart of each season.The trial, on …

Climate Of The Ord River Irrigation Area Western Australia, Implications For Crop Production, Rob J. Delane
Division of Plant Research : Technical Report Series
Management should be aimed at early planting to take advantage of higher soil and air temperatures, promoting rapid canopy closure, high final dry matter production and earlier calendar maturity. This will aid in attaining high yields, good grain quality, and low risk of harvesting delays or crop damage due to rain. However, early dry season planting is hindered by late maturation of some wet season crops, and excessive weed growth and slow soil drying following the wet season. The development (or adaption) of improved crop rotations, improved land utilisation and reduced tillage techniques will likely bring forward dry season planting …

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.

Experimental Summaries - Plant Research
Trial 87WH51
Location: Wongan Hills Research Station.
This trial was put onto a site adjacent to Mel Mason's source of nitrogen trial and the CSIRO, 15 N plots to provide some explanation of the results from the limited treatments in those trials. They were designed to monitor soil/fertiliser nitrogen transformations with time. Unfortunately the site of this trial was variable. The end most similar to the other trials was deeper and sandier and stored less water than the other and where crop growth was far better.

Post Emergence Weed Control In Lupins., R. Madin, J. Buckley
Experimental Summaries - Plant Research
As a general assessment in can be said that Tigrex is a safe and efficient herbicide for control of radish in wheat. Brodal alone was generally unsatisfactory for radish control. While Diuron + Brodal was safe and efficient, Ally and Brodal should not be used together. Diuron + MCPA gave poorer control than one would normally expect.
