A master’s thesis at the College of Agriculture, University of Kerbala, examined the effect of foliar application of thiourea and boron on the vegetative growth of sweet marjoram (Origanum majorana L.) and its essential oil content. The thesis was submitted by the student Rusul Fadel Nouri Al-Awadi.
The study aimed to evaluate the cultivation of sweet marjoram under Iraqi climatic conditions, particularly in Karbala province, and to assess the plant’s growth response to different concentrations of thiourea and boron, applied individually or in combination. The evaluation was based on vegetative growth characteristics and essential oil content.
The study recommended conducting further research on sweet marjoram in various agricultural environments to verify the consistency of the results and to enable broader application in commercial agriculture. Sweet marjoram is considered a rarely cultivated and underutilized plant in Iraq, despite its significant medicinal and industrial value and its wide use in food.
