Diseases Of Rape, A Bokor

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

A few serious outbreaks of disease occurred in rape crops in Western Australia in 1971 but future crop losses will be much greater where routine disease prevention is not practised.

Control measures for all these diseases are based on efficient destruction of crop residues by grazing and burning and by rotations which allow time for decay of below ground residues.

Symptoms Of Nutrient Deficiencies In Rape, M G. Mason, J. W. Gertrell

The appearance of mineral deficiency symptoms can vary considerably with growing conditions, so that symptoms produced in a glasshouse are only a guide to the probable symptoms in the field.

Nitrogen On Rapeseed, Department Of Agriculture, Western Australia

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

Experiments comparing the responses of wheat and rape to nitrogenous fertilisers were planted at 26 sites from Geraldton to Esperance in 1971.

In spite of hail damage and poor emergence of rape at some sites, meaningful results were obtained in 18 cases.
