Effect of time and rate of application of urea on wheat
1963
Littler, J.W.
A series of field trials involving the use of urea was carried out on a 70-year-old cultivation in the Pampas district of the Darling Downs in south-eastern Queensland. It was shown that the use of urea resulted in a higher level of soil nitrate, improved grain yields, improved grain protein, and to a lesse1· extent improved baking quality. Furthermore, the number of mottled grains was reduced with increasing rates of application of urea. An inverse correlation between protein content 1and grain mottling was shown to exist. Residual effects of the 1urea application were demonstrated in succeeding years. The economic aspect of this use of nitrogen fertilizer was investigated.
