Control Of Wild Oats, J G. Paterson

Journal of the Department of Agriculture, Western Australia, Series 4

WILD OATS are widespread throughout the world.

Their importance can be gauged from the fact that in the wheat growing areas of Canada and the U.S.A. some 60 million acres are infested.

Two chemicals are now available for the control of wild oats in wheat. This article compares their relative merits and gives recommendations for their use.

Serradella, H G. Cariss, B. J. Quinlivan

Journal of the Department of Agriculture, Western Australia, Series 4

SERRADELLA is an annual pasture legume which is now coming increasingly under notice.

Legume Inoculants For 1967, W A. Shipton

Journal of the Department of Agriculture, Western Australia, Series 4

PERIODIC changes are made in the strains of rhizobia released for the inoculation of various legume groups.

These changes are made when it is evident from experimental data that better strains of rhizobia are available, or that the old ones are no longer effective.

New strains of rhizobia may give improved nodulation of legume seedlings or increase dry matter yields.

Fertilisers For The Wheatbelt, William John Toms

Journal of the Department of Agriculture, Western Australia, Series 4

A review of fertiliser research findings and recommendations for fertiliser applications to crops and pastures in the 12 to 15 inch rainfall areas.

NOT long ago, fertiliser to the cereal grower meant only superphosphate for cropping. Today, phosphorus, sulphur, nitrogen, copper, zinc and molybdenum are all important, and the needs of improved pastures must be considered as well as those of cereals.

Recommended Cereal Varieties, 1967, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

THE wheat varieties Claymore, Gabo and Wagin have been withdrawn from the list of wheat varieties recommended by the State Wheat Advisory Committee for sowing this season, mainly because of their lower yield performances.

THE varieties Avon, Fulmark, Irwin and Kent are recommended for sowing in 1967 by the Coarse Grains Advisory Committee and the Department of Agriculture. The areas where satisfactory crops of these varieties can be grown are given in the map and table.

THE varieties Prior and Beecher are again recommended for sowing in 1967 by the Coarse Grains Advisory Committee and the Department of Agriculture.

The Control Of Doublegee, Geoffrey A. Pearce

Journal of the Department of Agriculture, Western Australia, Series 4

FOUR years ago no practical recommendations could be made for the control of doublegee.

With money provided by the State Wheat Research Fund, research has been undertaken into the control of this weed, and there is now no reason why most farmers cannot bring doublegee under control.

Watch Out For Afghan Thistle, J G. Paterson

Journal of the Department of Agriculture, Western Australia, Series 4

ALTHOUGH known throughout the cereal and sheep districts of Western Australia as Afghan thistle, this plant is not really a thistle at all.

It belongs to the large botanical family of the Solonaceae and is closely related to the garden vegetables tomato and potato.

Assessment Of New Potato Varieties In Western Australia, D. C. Hosking

Journal of the Department of Agriculture, Western Australia, Series 4

THE Mediterranean type of climate and low elevation of land in the South-West of Western Australia permits a year-round cycle of potato planting.

An early crop is planted in frost-free areas in June and July for harvest between October and December.

This is followed by a midseason crop, planted in August-October for harvest between December and March, and a late crop, planted November-April for harvest between March and September

Agriculture In Western Australia : Past, Present And Future, A W. Hogstrom

Journal of the Department of Agriculture, Western Australia, Series 4

THE post war period has seen very rapid growth and changes in the agriculture of Western Australia.

Almost every industry and region of the State has contributed to the growth of rural production which in turn has been responsible for much of the development in other sectors of the economy.

Journal of the Department of Agriculture, Western Australia, Series 4

Harbinger is an early-maturing medic that has met with success on some soil types, especially in the northern wheatbelt.

Similar to Cyprus barrel medic but best suited to different soil types, harbinger adds to the range of pasture legumes available for sowing in under 16 in. annual rainfall areas.

The highest yielding varieties in the 1965 barley variety trials were the two-row crossbred A l l , the white grained six-row varieties Arivat, Gem and Glacier and the recently-named two-row variety Dampier (previously known as W45).

Linuron : A Success In 1966?, Geoffrey A. Pearce

Journal of the Department of Agriculture, Western Australia, Series 4

Although some of the farmers who used linuron last year reported poor results, there is little doubt that this is the best herbicide since the advent of 2,4-D for weed control in cereals. This article gives the reasons for failure in some of last season's crops, and recommendations for use of linuron in 1967.

The Control Of Weeds In Cereals, Geoffrey A. Pearce

Journal of the Department of Agriculture, Western Australia, Series 4

PROBABLY the simplest way of obtaining an increase in crop yield is to control the weeds present.

Nearly a million acres of cereal crops are sprayed by aircraft each year and when the area treated by ground units is added, something like 20 per cent of the total area sown is sprayed with herbicides.

Journal of the Department of Agriculture, Western Australia, Series 4

THE use of nitrogenous fertilisers has become an important aspect of cereal growing in many districts and farmers now have a number of sources of nitrogen from which to choose.

The History, Characteristics And Potential Of Kondinin Rose Clover, E T. Bailey, N. B. Gayfer

Journal of the Department of Agriculture, Western Australia, Series 4

Experimental and field performances of rose clover over fen years suggest that it will be increasingly used as a pasture legume in south-western Australia.
