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 …

Effect Of Agronomic Practices On Wheat Protein Levels, M G. Mason

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

High grain protein levels are preferred for many end-uses of wheat. However, there has been little or no incentive for farmers to use practices which would increase protein levels, because wheat payments are made without a price differential for proteinlevel, except where wheat could qualify for the Australian Hard grade.

Nitrogenous Fertilisers For Cereal Production, M G. Mason

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

Among the many factors influencing crop response to nitrogen applications, the most important are the season, soil type, paddock history, time of application and source of nitrogen. Before deciding whether to use nitrogen on a cereal crop, which source to use and at what rate, the farmer needs some understanding of how these factors work.

Legumes Or Artificial Nitrogen?, N J. Halse

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

Choosing between legumes and artificial nitrogen is not the problem which many farmers are making it.

This article deals with the choice in the mixed cereal and sheep farms of the Western Australian wheatbelt.
