The Nitrogen Response Of Wheat Crops Following Lupins, I C. Rowland, Mel Mason, John Hamblin
The Nitrogen Response Of Wheat Crops Following Lupins, I C. Rowland, Mel Mason, John Hamblin
Journal of the Department of Agriculture, Western Australia, Series 4
One of the many benefitsof growing narrow-leaved lupins in a crop rotation (Rowland et al 1988) in the increased yield of the following cereal crop as a result of the improved nitrogen level of the soil.
This article reports the results from 41 wheat/lupin rotation trials involving a range of nitrogen rates throughout the Western Australian agricultural area between 1978 and 1987. These trials allowed scientists to assess the interaction of nitrogen fertilization with previous cropping history and to estimate some of the contribution of the nitrogen and other effects of lupins within the crop rotations. The results provide some …
Frost Injury To Wheat, S P. Loss
Frost Injury To Wheat, S P. Loss
Journal of the Department of Agriculture, Western Australia, Series 4
Frost injury has not been a major concern to the Western Australian wheat industry despite causing spectacular but irregular crop losses on some farms.
The development of suitable herbicides, direct drilling technology and the adoption of early flowering varieties in the late 1970s and early 1980s led to wheat crops being sown and flowering earlier than previously. This resulted in an increase in the incidence of frost damage.
Research into frost indicates that most wheat producers face low to moderate risks of yield loss caused by frost. However, individual farms in particular years can suffer devestating widespread losses. Grost injury …

Flower : Predicting Flowering Times Of Cereal Crops, G A B Elliott, Stephen Loss
Journal of the Department of Agriculture, Western Australia, Series 4
FLOWER is a computer program which predicts the flowering date of a given wheat or barley variety at a specified location and sowing date. Department of Agriculture agronomists, breeders and advisers are using the program to provide useful information on how the development of cereals responds to different environments across Western Australia's cereal growing areas.
Leaf Diseases Of Wheat And Time Of Sowing, J M. Wilson
Leaf Diseases Of Wheat And Time Of Sowing, J M. Wilson
Journal of the Department of Agriculture, Western Australia, Series 4
Leaf diseases of wheat can be avoided by delaying the planting of a crop, but this often leads to reduced yield because the benefits of early sowing usually outweigh anylosses caused by leaf disease.
However, it is only in exceptional circumstances that farmers need to consider leaf disease when making decisions about planting date, as this article shows. Most examples are taken from department of Agriculture trials in its northern advisory region, but the principals apply to other agricultural areas.

Increased Returns From Agronomic Inputs In Early Sown Cereal Crops, W K. Anderson
Increased Returns From Agronomic Inputs In Early Sown Cereal Crops, W K. Anderson
Journal of the Department of Agriculture, Western Australia, Series 4
When crop variety and soeing dae are matched so that flowering occurs in the 'window' for a particular site, grain yields are increased and yield response to inputs such as nitrogen fertilizer and seeding rate is magnified.
This response occurs because the srop's potential for setting and filling grains is much improved by sowing at the optimum time. However varieties differ in their yield potential because they have different lenghts of growing season, which probably affects grain numbers, and because they have different inherent grain sizes. These differences affect the way varieties react to sowing date. Figure 1 shows how …
Early Sowing : One Key To Improved Yields Of Cereal Crops, M W. Perry, Wal Anderson, Rob Delane
Early Sowing : One Key To Improved Yields Of Cereal Crops, M W. Perry, Wal Anderson, Rob Delane
Journal of the Department of Agriculture, Western Australia, Series 4
Early sowing of cereal crops is one of the most important management practices through which Western Australian cereal growers can increase yields.
Researchers have long known that in theory early sowing should mean improved growth and water use efficiency - which both contribuite to increased yields. Application of this knowledge has had to await new tillage and herbicide technology, but recent research in the northan and central wheatbelt has now demonstrated the advantages of early sowing in practice. And more exciting yet, there is evidence that yield responses to weed control and applied fertilizers may also be greater in early …

Early Sowing Of Ceral Crops In Low Rainfall Areas, R J. Delane, John Hamblin
Early Sowing Of Ceral Crops In Low Rainfall Areas, R J. Delane, John Hamblin
Journal of the Department of Agriculture, Western Australia, Series 4
One of the objectives of the Department of Agriculture's crop research in the low rainfall, northern wheatbelt is to develop crop varieties and management practices that will make best use of stored water on both sandplain and fine textured soils. Sowing a crop early will improve its water use efficiency and yiel in low rainfall areas.
