Two field of experiments were conducted during two successive growth seasons 1997 and 1998 at the Experimental Station of the National Research Centre to study the effect of ethephon and zinc sulphate concentration as well as their combination on vegetative growth, yield and its attributes and some biochemical constituents of maize plants. The data indicated that spraying ethephon with different concentration led to SignifiCant increases in stem diameter at all growth stages while, foliar application of ethephon at concentration 100 g/fed to maize plants caused a significant reduction in vegetative growth characteristics, i.e. plant height, leaf area, leaf area index, specific leaf weight, crop growth rode, and dry weight/plant at the different stages of growth compared with 50 g/fed etbephon.
