| Abstract | ||
| The present study was carried out during two successive seasons of 2016/2017 and 2017/2018 at the Nursery of Ornamental plants, Fac. of Agric., Minia University, to study effects of saline water irrigation (250, 1000, 1750 and 2500 ppm) as the main plot and humic acid (control, 100, 200 and 400 mg/l.) as the sub plot and the interaction between them on vegetative growth traits (plant height, number of branches and herb dry weight/plant), fruit and essential oil productivity, as well as, some chemical composition (photosynthetic pigments, nitrogen, phosphorus, potassium, sodium, calcium and proline percentages) of caraway. Under irrigation with saline water ranged from 1000 and 1750 ppm, all studied vegetative growth characters were significantly increased such as fruit yield/plant, oil % and oil yield/plant and some chemical composition (photosynthetic pigments, N, P and K %). Also, humic acid treatments increased all studied parameters but decreased proline %. From results of this research it could be concluded that, caraway plants are moderately tolerant to salinity stress and can be vigorously grown under irrigation with saline water ranged from 1000 to 2500 ppm when sprayed with humic acid at 400 mg/l. | ||
