| Abstract | ||
| The current study was done in net greenhouse at Roof of Horticulture Department, Agriculture Faculty, Zagazig University, Egypt during 2022/2023 and 2023/2024 seasons. The main factor was saline water irrigation level at (0.0, 1000, 2000 and 3000 ppm), whereas, the sub factor was nano-micronutrient rate at (0.0, 250 and 500 ppm) beside the combination treatments between the two factors. However, the plant height, branches number per plant, fresh and dry weights per plant, salt resistance index and root system of sweet basil responses were determined. Increasing saline water levels gradually decreased growth and salt resistance index as well root length and fresh and dry weight of roots per sweet basil plant to reach the lowest values with 3000 ppm in the two cuts during both seasons. In contrast, all growth and root system parameters were increased as nano-micronutrient rates increased. Furthermore, the utilizing nano-micronutrients at 500 ppm significantly enhance salt resistance index of sweet basil to reach 129.16 and 135.83 % without salinity stress, 115.39 and 126.76 % with 1000 ppm of saline water level and 101.82 and 115.14 % with 2000 ppm of saline water level. In general, it is preferable to utilize micronutrients as nano-particle to decrease a harmful impact of saline water irrigation on the growth and root system of sweet basil plants. | ||
