| Abstract | ||
| Two Lyzimeter experiments were conducted at Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt, for two seasons, 2007/2008 and 2008/2009. Lyzimeters (100 x 70 x 90 cm) were filled with clayey soil and irrigated with three water treatments since twenty years ago. The present study aimed to investigate the effect of irrigation water quality for long-term on productivity of four Faba bean varieties (Sakha 2, Giza 461, Giza 3 and Giza 843). Three irrigation water qualities; Nile water (W1), polluted drainage water (W3) and mixed water; W2 ( 50% W1 + 50% W3) used for irrigation to study its effects on faba bean contents from four heavy metals Ni, Cd, Pb and Cu and some soil characteristics. A split–plot design with four replicates was used where, water treatments and varieties were allocated to main and sub-plots, respectively. The obtained results showed that: Using poor water quality for irrigation increased ECe, SAR, soluble cations and anions in soil paste extract and DTPA extractable heavy metals in soils (Cu, Ni, Cd and Pb) than that of mixed or good water quality. Highly significant differences of yield and yield components between faba bean verities were found due to irrigation water treatments and its contents of heavy metals. Content of the studied heavy metals were in the following order; roots > leaves > coat of seed >cover of pod > seeds. The results showed that Sakha 2 was more tolerant variety to drainage and mixed water and its contents of Ni, Pb and Cu were lower than Giza 3, Giza 843 and Giza 461. No significant differences were found between all studied faba bean varieties used for Cd content. The content of seed faba bean varieties from heavy metals can be arranged as follow: With Pb: Sakha 2 = Giza 3 < Giza 461 < Giza 843 With Cu: Sakha 2 < Giza 843 < Giza 3 < Giza 461 With Ni: Sakha 2 < Giza 3 < Giza 843 < Giza 461 | ||
