Clover Ley Farming In Western Australia : An Important Research Project, T C. Dunne Jan 1962

Clover Ley Farming In Western Australia : An Important Research Project, T C. Dunne

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

IT is an accepted fact that the pasture period developed as an alternative to cropping in areas where cereals are grown results in increased fertility and a potential for higher cereal crop yields.

Successive Crops In A Clover Ley Rotation, H M. Fisher

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

Recent investigations suggest that cereal production on clover leys in the medium rainfall region can be increased by growing a succession of cereal crops after the pasture phase.

In most areas accumulated fertility after four to five years of clover pasture will support two, and in some cases three, high yielding cereal crops grown in succession.

Where root rot diseases are prevalent it is an advantage to sow oats as the initial crop.

Root Diseases In Wheat On Clover Ley : Factors Under Investigation. 1. The Role Of Oats After Ley, S C. Chambers

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

The role of oats in relation to root diseases of wheat was examined at four of the State Wheat Research Stations.

Several recognised pathogenic organisms were isolated in the course of the investigation, the most important being Ophiobolus graminis, which is the cause of "take-all."

Results suggest that one year under oats after clover ley is sufficient to reduce the incidence of take-all, except when seasonal conditions are extremely favourable to the disease.

In areas where take-all is a problem, wheat planted after a first crop of oats can sometimes give a higher yield than a first crop of wheat. …

THE agricultural districts of Western Australia have a typically Mediterranean climate.

Most of the annual rains fall in the late autumn, winter and early spring. The winters are relatively warm, with day temperatures between 50° and 80° Fahrenheit, while the summers are very hot and dry.
