Experimental Summaries - Plant Research

Trial 87ME77

Location: Eastern Wheatbelt.

One of the better sites in terms of productivity. This site was sown at two times, initially 4 reps were sown but as it was very dry the remaining 8 reps were sown after additional rain. This split seeding did not seem to adversely affect the trial

Trial 65sg5, I Rowland., W Hawkins

Experimental Summaries - Plant Research

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.

Wheat And Barley Experiments On The Kumarl Soils At Salmon Gums, D A. Collins, Michael D A Bolland, R D. Fletcher

Field Peas In The Wheatbelt, R J. French

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

Plantings of lupins in the Western Australian wheatbelt increased rapidly in the late 1970s and early 980s as improved varieties became available and farmers realised the benefits to be gained from growing grain legumes. Grain legumes are useful not simply as alternative cash crops. They provide 'fixed' atmospheric nitrogewn to following cereal crops and act as a cleaning crop to break cereal disease cycles. They are also valuable sheep feed.

In 1975, throughout the wheatbelt, the Department of Agriculture began a comparison of several alternative legumes. The crops included field peas, faba beans, chickpeas, lentills and various vetches. Field peas …

Gypsum Use In The Wheatbelt, M R. Howell

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

One of the limitations to crop productivity in the wheatbelt is the poor structure of heavy textured soils. Many years of clearing and cultivation have caused the loss of soil organic matter and breakdown of soil aggregates - particles of sand, silt and clay - in the surface layers. This has led to the development of unstable soils with poor physical properties.

Although loss of soil structure is a serious problem, it can be reversed by altering the tillage practices that caused the problem. This improvement in soil structure and return to productivity can be a slow process. However gypsum …

Phosphorus Levels And Disease On Lupins, J W. Bowden

Experimental Summaries - Plant Research

Trial 87LG39 (81LG29) 87ME62

Location: Pingaring.

It has been suggested that high levels of phosphorus application to lupins can reduce the impact of leaf and root diseases. Two old rotation trials provided a range of disease burdens, across which phosphate rates on lupins were applied. Disease scores, vegetative yields, phosphorus concentration and seed yields were measured.
