| Abstract | ||
| The lack of freshwater for rice cultivation has emerged as a significant issue, prompting rice farmers in Egypt's northern delta to use low-quality water for rice crops, which is deemed a disastrous situation. Two field trials were carried out during the summer seasons of 2022 and 2023 at the farm of Sakha Agriculture Research Station, Sakha, Kafr El-Sheikh, Egypt, to investigate the effect of using various ratios of freshwater to drainage water on soil quality and behaviours of some rice cultivars specifically; Giza 183, Giza 178, Sakha106 and Sakha108. A strip plot design featuring four replicates was employed in the experiments. The vertical plots focused on five types of water qualities as follows: Freshwater (FW), drainage water (DW),1FW: 1DW, 2FW: 1DW, and 1FW:2DW, rice varieties were put in horizontal plots. The results indicated that, highest level of heavy metals was found in drainage water which, diminished soil quality and raised heavy metals in rice grains, along with its harmful impact on rice growth, yield, and its components. The treatment of freshwater was the most effective, followed by 2FW: 1DW. The treatment of 2FW: 1DW is appropriate and cost-effective for watering rice plants, particularly during times of limited freshwater availability. Giza 183 and Giza178 cultivars are more resilient in drainage water compared to other varieties. It could conclude that poor quality water mixed with freshwater (2FW: 1DW) had profitability of rice, produced safely heavy metal level in soil and rice grains, along with cultivated both Giza178 and Giza183 rice varieties. | ||
