Field trials with Spathiphyllum wallisii Regel were conducted at the experimental farm of Faculty of Agriculture, University Azad Jiroft in 2012 growth seasons. The aim of this work is to study the effect of foliar application with benzyladenine (BA) at 0, 100, 200 and 400 mg.L-1 and gibberellic acid (GA3) at 0, 100 and 200 mg.L-1 on the vegetative growth constituents of Spathiphyllumplants. Most of the criteria of vegetative growth expressed as number of leaves/plant, leaf area and petiole length and were significantly affected by application of the two factors which were used in this study. All foliar applications of SPAD BA and GA3 separately promoted all the aforementioned characters in this study, as well as chl. a, petiole length, number of leaves/plant, leaf area and spad compared with control plants. The most  number  of  produced leaves  was in a plant  in applications of 400 mg l-1 of  BA, 100 mg l-1 of BA, 400 mg l-1 BA+100 mg l-1 GA3 , 400 mg l-1 BA+mg l-1 of  GAand respectively,  with average of 11/33, 11,10/66, 10/66  that  they did not  show a meaniful diference, statically.
