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.

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. 1. Survival Of Rhizobia On Inoculated Pelleted Seed Held For Varying Periods Before Sowing Into Dry Soil, O M. Goss, W. A. Shipton
Journal of the Department of Agriculture, Western Australia, Series 4
MOST of the light land areas being opened up in Western Australia are very sparsely populated with the rhizobial bacteria so essential for successful legume establishment.
Seed inoculation is therefore a necessity.
Farmers often have to resort to dry sowing because of the large acreages being planted or late opening rains.

Lot Feeding Of Beef Cattle. 5. Feed Lots And Animal Health, W J O Wilkie
Journal of the Department of Agriculture, Western Australia, Series 4
BRINGING cattle from various sources together in a feed lot makes them more liable to disease than they would be in the open paddock.
Precautions, careful selection, prevention and vaccination can reduce the risk of disease and the possible need for treatment during the feed lot fattening period.
Nodulation Of Legumes On New Light Land. 4. Rhizobial Strains For Pasture Establishment, O M. Goss, W. A. Shipton
Nodulation Of Legumes On New Light Land. 4. Rhizobial Strains For Pasture Establishment, O M. Goss, W. A. Shipton
Journal of the Department of Agriculture, Western Australia, Series 4
LEGUMES are the basis of improved pastures in Western Australia.
Successful establishment of these legumes depends on the presence in the soil of suitable bacteria which will invade the roots and develop nodules in which nitrogen fixation is carried out. The nitrogen compounds produced are utilised by the plants, making them independent of soil nitrogen.
At the end of the season, the decomposition of the plant residues improves soil fertility.

Agriculture In Western Australia. 3. The Economic Potential Of The Wongan-Ballidu Shire. Part 1, G D. Oliver, A. W. Hogstrom
Journal of the Department of Agriculture, Western Australia, Series 4
IN West Australian agriculture there is a considerable "backlog" of information available to farmers which is not being used in practical farming. This, of course, is true of agricultural industries anywhere in the world.
This "backlog" results in a big difference in productivity between the best farms and the "average" farms in each district.
This article is a simple economic study of the potential of one shire of Western Australia.

Lot Feeding Of Beef Cattle. 3. Facilities Required For A Feed Lot, W J O Wilkie
Journal of the Department of Agriculture, Western Australia, Series 4
MANY THINGS must be considered in planning a feed lot.
The site must be well chosen, fencing, gates and yards must be adequate for the cattle carried and feeding and watering facilities should be of a high standard.
Other things to consider are the provision of shelter and shade for the cattle and buildings for feed storage and other purposes.

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.

Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson
Sheep Can Be More Profitable In The Wheatbelt, G T. Halpin, P. Nelson
Journal of the Department of Agriculture, Western Australia, Series 4
TRADITIONALLY, wheatbelt farmers have looked upon sheep as being subsidiary, or at best, complementary to their main activity, wheat growing.
Because there has been a mistaken belief that clover would not grow, these farmers have depended upon native grasses and crop remains (stubble) for sheep feed, a practice which has put a limit to the number of sheep a property could support.
