%X Three surveys in southern New South Wales assessed the importance of a number of agronomic factors on grain protein content. Grain from clover ley areas had an average of 1.3 per cent more protein than grain from crops without a clover ley background. Multiple regression analyses of the 1961 and 1963 data from clover ley crops showed that each year of ley was associated with an average increase of 0.14 per cent protein. Each week's delay of sowing beyond April 1, was associated with an average increase of 0.17 per cent grain protein. Amount of superphosphate applied to ley, intensity of cropping, and length of fallow had no effect or inconsistent effects on grain protein. With crops after natural leys only sowing time had a consistent effect on grain protein. The regression was the same as for crops with a clover ley background.
