Nitrogen Fertilisers And Cereals, M G. Mason

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

FEW aspects of cereal growing have received as much attention in the past 20 years as nitrogen fertilisers.

The recommendations and yield figures presented below are based on numerous trials in the agricultural areas of Western Australia.

A Comparison Of Methods Of Urea Application At Ajana, M G. Mason, R. J. Parkin, H. Patrick

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

Compared with urea application separate from the seed, urea mixed with wheat seed delayed and reduced wheat germination, and reduced wheat yields, especially at high rates of urea.

Yields were higher where the urea was topdressed immediately before seeding than where it was top-dressed either immediately after, or two weeks after seeding.

Trials With Urea And Anhydrous Ammonia For Wheat Growing, M G. Mason

THE recent subsidy on nitrogenous fertilisers has greatly reduced their price to farmers. This, and farmers' increasing awareness of the benefits of application of nitrogen to cereals, has led to a substantial increase in the use of these fertilisers.
