| Abstract | ||
| A pot experiment was conducted under greenhouse conditions using broad been plant (Vicia faba L.). Irrigation water salinity was achieved by diluted sea water collected from Suez Canal to reach salinity levels of 2.43, 4.33 and 6.10 dSm-1. Nitrogen was added as ammonium nitrate at the rates of 60, 45, 30 mg N kg-1 soil corresponding to 100, 75 and 50 % from recommended dose which is 60 kg N fed-1. Bio fertilization was achieved through the addition of rhizobium which was thoroughly mixed with surface soil. Plant samples were collected at three different growth stages i.e. 45, 75 and 140 days from sowing corresponding to flowering stage, pod formation stages and maturity stages, respectively. Results showed that, at flowering stage, the highest values of plant height, number of leaves, and dry matter content as well as P and K uptake were observed under the treatment of 60 mg N kg soil-1 + Rhizobium. At the pod formation stage, the highest values of plant height and number of leaves were observed under the treatment of 60 mg N kg-1 soil+ Rhizobium, while the highest values of dry matter content and as well as P and K uptake were obtained under the treatment of 45 mg N kg-1 soil + Rhizobium. At maturity stage, the highest value of dry matter content was observed under the treatment of 60 mg N kg-1 soil+ Rhizobium, while P and K uptake, and pods number per plant were obtained under the treatment of 45 mg N kg-1 soil + Rhizobium. | ||
