Correction of zinc deficiency in maize on the Darling Downs, Queensland

Duncan, O.W. (1967) Correction of zinc deficiency in maize on the Darling Downs, Queensland. Queensland Journal of Agricultural and Animal Sciences, 24 (3). pp. 293-300.



Zinc applied as a 0·5% zinc sulphate spray completely corrected symptoms of zinc deficiency. Copper, boron, magnesium, potassium and phosphorus applied as foliar sprays did not correct symptoms. Concentration of solution (0·5, l·0 and 1·5 %) and number of applications (1 and 2) did not affect plant response significantly. There is evidence in one trial, and a trend in the other, to indicate that spraying at 7 weeks from emergence is too late for zinc sprays to increase yield, and that the optimum spraying time appears to be at about 5 weeks after emergence. Yield increases from zinc foliar sprays ranged from 24 to 76% over control.
