Control Of Prodenia Litura On Cotton In The North Of Western Australia, P N. Forte, D. G. Shedley

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

COTTON is subject to considerable insect attack at the new Ord River irrigation area in the East Kimberleys of Western Australia.

Although a long list of insects have been recorded as damaging cotton in this area there are two which have proved so far to present the biggest problem.

These are Heliothis punctigera and Prodenia litura.

Maintaining The Quality Of Western Australia's Oat Harvest, J L. Mcmullan, J. A. Parish, C. V. Honner

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

WESTERN AUSTRALIA deservedly enjoys the reputation of being a producer of oats of high milling quality.

Because of this, we have been able to develop valuable export markets which pay a premium for our oats.

For some time Ballidu has been rated as the best milling oat in W.A.

The work reported in this article indicates that other recommended varieties are equal to or better than Ballidu for milling.

Nodulation Of Legumes On New Light Land. 2. Protection Of Rhizobia From The Toxic Action Of Superphosphate And Trace Elements, O M. Goss, W. A. Shipton

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

VAST areas of new light land being developed in Western Australia are deficient in trace elements such as copper, zinc and molybdenum as well as in phosphorus.

These fertilisers are known to be damaging to the rhizobial bacteria inoculated on the seed unless they are protected by lime pelleting.

Nodulation Of Legumes On New Light Land. 3. The Effect Of Rogor Seed Treatment On Legume Nodulation, O M. Goss, W. A. Shipton

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

SEED treatment with systemic insecticides is widely used for the control of insect pests. However, when seed inoculation is necessary for pasture establishment, seed treatment with insecticide is not advisable.

A field experiment conducted at Badgingarra Research Station in 1964 showed that the systemic insecticide Rogor was very damaging to the applied rhizobia even when the treated seed was held for a month before inoculation.

The Control Of Weeds In Orchards, Geoffrey A. Pearce, S. E. Hardisty

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

THE use of herbicides for the control of weeds in orchards has become established during the past few years.

It has become more efficient with the introduction of newer herbicides which have proved more effective and less dangerous than some of those recommended in the past.

The Starling, John L. Long

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

Despite their pretty colour and their song, starlings cannot be considered beneficial, especially in the fruit and grain-growing areas of W.A. where they are declared vermin.

MILLIONS of starlings inhabit the settled parts of eastern and south-eastern Australia, but so far they have not reached Western Australia.

Two different soil types may show the same acidity levels by soil test but they may need different amounts of limestone to obtain the same reduction in soil acidity.

Nitrogen Loss From Surface Application, Harold F. Miller

Agronomy Notes

Research work has shown that considerable nitrogen can be lost from surface applied ammonia-containing fertilizers. The nitrogen is lost due to the formation of ammonia which escapes into the air. Soil and weather conditions encouraging this loss are high temperature, moist soils, high pH and source of nitrogen.

Seed And Pasture Rates For New Dairy Pastures, F E. Ryan

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

THE success or failure of pasture establishment on new land often depends on the interaction of rate of seeding and rate of superphosphate application.

Every year large areas of virgin land are cleared and sown to pasture in the higher rainfall areas, and all-too often the new pasture is not as successful as it should be because too little super is applied, and, in some cases, too little seed.

Plant Nutrition In Western Australia, George Henry Burvill

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

PLANT nutrition is of great practical importance in Western Australia.

Without a well developed fertiliser industry and research and experiments to guide farmers in appropriate fertiliser use the State's agriculture would be very restricted.

Preserve And Use Tobacco Stalks, George D. Corder

Agronomy Notes

When Kentucky's 1964 tobacco crop is stripped , there will be about 176,000 tons of stalks in and around stripping barns. There will be more than $2 million worth of nitrogen, phosphorus and potassium in them.

If these stalks are left outside the barn and exposed to winter rains, 61 percent of the nitrogen, 38 percent of the phosphorus, 83 percent of the potassium and 41 percent of the organic matter may be lost.
