atrinal, naphthalenear:ptir: ar:id (NAA) and kinetin as well as two foliar fertilizers,Grpellzit and Bayfolan at different concentrations and at diffcr!:,”: time of application as well on the vegetative growth alld the volatile oil production of sweet mr:lrjoram plants (HajorClnrl hortensis) ,Moench. Therefore, two separate split plot experiments with four replications were conc1llcted. 1’hp combined effect of the growth reguL:itors and the foliar fertilizers WrlS Cllso studied jn Cl separate exper iment.
