Abstract

The present experiment was conducted during the autumn of the year (2012) in the city of Al-Diwanyia (Iraq). The goal of the experiment was to find the effect of different types of Antitranspirants (each type with two Concentrations), Salicylic acid (with and without treatment) and  irrigation intervals(5,10 and 15 days), and their interactions on some Vegetative growth  characteristics  of Maize (zea mays L.) The experiment was designed in a randomized complete blocks (RCBD), in a Factorial arrangement (3*2*7) with three replications. The Revised Least Significant Difference (RLSD) at 0.05 probability level was used to compare treatments means, whenever treatment effects were evident. The Antitranspirants and Salicylic acid (first treatment) as well as  irrigation intervals were applied at (4- 5 fully expanded leaves) stage. While the second application of  Antitranspirants and Salicylic acid,  was after a month,  at the beginning of tasseling ( 50%). Several Vegetative growth  characteristics was measured, including plant height, stem diameter, leaf area, total chlorophyll, dry shoot weight, dry root weight and root : shoot ratio.  Results showed: 1- The use of The antitranspirant Kaolin (40mg.L-1)  increased   plant height, Shoot Fresh Weight, While the antitranspirant sodium salicylates showed beneficial effect by increasing the root dry weight, Root: Shoot Ratio. 2- Foliar application of Salicylic acid decreased all parameters studied except leaf content of chlorophyll. 3-The irrigation of  5-day interval succeeded in increasing the plant height, fresh  and dry root weight and root : shoot ratio. While the irrigation of 10-day interval gave best results concerning the increase in chlorophyll content, leaf area, as well as  dry shoot weight. The irrigation of 15-day interval had a Significant impact in decreasing  all parameters studied. 4- Triple interaction between the three factors included in the experiment revealed significant effect on all parameters studied.
