| Abstract | ||
| This investigation was carried out at the experimental farm of the faculty of Agriculture , Menoufiya Univ at Shiben El-Kom during to growing the seasons of 2016/2017 and 2017/2018 for studying the effect of some cultural treatments such as irrigation with magnetic water and bio and ammonium nitrate fertilization levels individually or in combinations on the vegetative growth parameters , essential oil content and some chemical constituents of Majorana hortensis L. plants. The obtained results showed that the growth parameters such as plant height , number of branches per plant , fresh and dry weight per plant as well as per feddan were markedly improved as a result of watering Majorana hortensis L. plants with magnetic water besides using bio fertilizers ( Rhizobium, Azotobacter and Azospirillium ) plus ammonium nitrate fertilization at its different rates ( 0 , 100 , 200 and 300 kg/fed ) . The best results in this respect were obtained by using magnetic water , Azotobacter fertilizer application and the moderate level of ammonium nitrarte fertilization ( 300 kg /fed ) . Furthermore , the highest essential oil content , NPK percentages as well as photosynthetic pigments concentrations and total carbohydrate content were realized by the same treatment in the two growing seasons . On the other hand the control treatment ( irrigation with ordinary water without using either bio or chemical fertilizer ) gave the lowest growth and yield parameters as well as the lowest chemical constituents of the plant in the two experimental seasons . | ||
