| Abstract | ||||
| The enhancement of industrial activities led to an increase of heavy metals in the AbSament, which affected badly soil properties, plant, groundwater, and human health. In envien the accumulation of salts within the soil produced harmful effects on plants by adeesing the osmotic potential of the soil solution. On the other hand, the needs to save igation water and the use of low water quality for irrigation were of high concern. So, the aim of this work is to investigate the effect of salinity and chromium in irrigation water and the interaction between them on the growth parameters of sugar beet. The sandy soil was collected from El-Sadat City, a newely reclaimed area, and analyzed chemically and physically, e.g., pH, EC. soluble cations, and anions. A completely randomized block design experiment was carried out which contained three concentrations of brackish water having EC 0.5, 4, and 8 dS/m and five concentrations of chromium were 0,5,10,20 and 40 ppm. The different saline water was enriched with the chromium concentrations to show the effect of chromium on the growth parameters of sugar beet. The EC of 0.5 represents the control of treatment. After 4 and 6 months, plants were collected and analyzed for chromium concentration, and their growth parameters were measured.From the obtained results, it can be concluded that the EC of irrigation water had not significantly affected the growth parameters except at EC 8 dS/m due to tolerance of sugar beet to salinity up to 4 dS/m. While the irrigation with Cr-enriched brackish water (Cr concentration ranged from 5 ppm to 40 ppm) reduced significantly the growth parameters of sugar beet. Both parameters of the two stages of growth showed significant correlation with the chromium. The reduction in fresh weight reached 85.7% and in dry weight was 89%, while in root size it reached 96%. Also, the data indicates that in spite of the insignificance effect of EC on crop productivity, yet the phytotoxic effect of Cr even at low concentration (5 ppm) was clear enough. In addition, the capacity of the roots to accumulate Cr increased with the increase of both Cr and EC in irrigation water. That is, a high portion of the total amount of Cr taken up by the plant was retained in the roots, where only a small amount was translocated to the shoots. So, this study recommended that sugar beet can be cultivated in reclaimed land with poor quality of water (i.e, water with high salinity up to 4 dS/m). But, the irrigation water must have low level of Cr content less than 5 ppm due to its toxicity and damaging effects on growth parameters of sugar beet and health hazards on human being. Also, the Egyptian Food Authority should establish maximum allowable limits for Cr concentration for irrigation water and for vegetables, fruits, and field crops to avoid its harmful health effects. | ||||
