| Abstract | ||
| To investigate the effect of different types of nitrogen fertilization the growth and productivity of thyme within reducing the harm effects of the excess of nitrogen fertilizers as an environmental and healthy problems, two successive experiments were carried out in pots during 2016, 2017 season's at the experimental green house Faculty of Agriculture, Ain Shams University Cairo , Egypt. Three types of nitrogen fertilizers amonium nitrate, ammonium sulphate and Urea, with three concentrations (40%, 60%, 80%) were used. Data showed an increase in number of lateral branches, plant height and amino acids with 40 units of ammonium nitrate, while the best effect to reduce NO3, NO2 as a lowest value was 40 units of ammonium sulphate. The highest value of herb fresh weight was recorded by 40 units of urea, (42:48 g / plant) while herb dry weight ( 18:54 g/ plant ) by 40 units of ammonium sulphate, volatile oil (0.92 % v/ w) with 60 units of ammonium nitrate , amino acid (3.71 g / 100 g fw ) with 80 units of urea. thyme plants, nitrogen fertilizers, growth parameters, oil quality. | ||
