| Abstract | ||
| This study was conducted to evaluate the effects of irrigation water quality on some soil physical properties and plant growth of tomato grown in saline soil. Recycled water (1.5 dS/m) and mains water (0.62 dS/m) were used. The experiment was laid out as a randomized complete block design. The results showed that using mains water for irrigation under saline soil conditions induced clay dispersion; as a result soil structure destruction was more evident in soil irrigated with mains water. Regarding plant growth, recycled water reduced both total leaf area and above-ground dry biomass. Water use efficiency (WUE) was greater when mains water was applied. Blossom End Rot (BER) was more evident with recycled water plants. Thus, yield of tomato was reduced with increasing salinity. Key words: Saline soil, Recycled water, Soil physical properties, Plant growth, Blossom End Rot. | ||
