Studying the effect of irrigation water quality (fresh water, treated water and wastewater) on some soil physical and chemical properties and the protein content in the paulownia leaves

Sawsan Jabra Mansour — 2024-09-17

Samples of soil irrigated with three types of water: Fresh water (F), wastewater (W), fresh water and wastewater (F1W1, alternative irrigation) were collected at two depths (0-15 cm and 15-30 cm) for two consecutive years. The bulk density, true density, soil total porosity, electrical conductivity, pH, percentage of organic matter, and concentration of phosphorus and potassium were measured. In addition, the length and circumference of paulownia tree trunk were measured, and the protein content of dry and green leaves was estimated. The results showed the differences in the apparent density values, as wastewater irrigation decreases the apparent density and increased the soil total porosity. The results also indicated that there were significant differences in the soil PH between the three treatments, as treated water irrigation decreased the pH and insignificantly increased the soil electrical conductivity. However, there were significant differences when irrigating with wastewater, as the electrical conductivity and organic matter content increased in the soil irrigated with wastewater compared to soil irrigated with fresh water at two depths (0-15cm and 15-30cm). Moreover, the concentrations of phosphorus and potassium increased in the soil irrigated with wastewater and treated water compared to fresh water. Furthermore, there were significant differences in the height of paulownia tree and its trunk circumference when irrigating with treated water compared to wastewater and fresh water. As for the protein content in paulownia leaves, it was observed that there were significant differences when irrigating with wastewater compared to treated water and fresh water. There was high protein content in the dry and green leaves when irrigating with the three types of water, but the highest protein content was for wastewater irrigation.

While the second factor included 9 fertilizer treatments (control, adding boron at a level of 10 kg ha^-1, adding boron at a level of 20 kg ha^-1, spraying tyrosine at a concentration of 100 mg L^-1, spraying tyrosine at a concentration of 150 mg L^-1, adding boron at a level of 10 kg ha^-1 + spraying tyrosine at a concentration of 100 mg L^-1, adding boron at a level of 10 kg ha^-1 + spraying tyrosine at a concentration of 150 mg L^-1, adding boron at a level of 20 kg ha^-1 + spraying tyrosine at a concentration of 100 mg L^-1, boron addition at a level of 20 kg ha^-1 + spraying of tyrosine at a concentration of 150 mg L^-1), they are indicated by symbols (T1, T2, T3, T4, T5, T6, T7, T8 and T9). The results showed that the T9 treatment (boron addition at a level of 20 kg ha^-1 + spraying of tyrosine at a concentration of 150 mg L^-1) was superior in leaf content of nitrogen, phosphorus, potassium and boron, with averages of (2.770%, 0.5533%, 2.3800% and 41.50 mg kg^-1), respectively. The same treatment also excelled in plant height, leaf area, root weight and yield marketing averages of (48.908 cm, 180.90 cm², 275.8 g plant^-1 and 45.34 ton ha^-1), respectively. The results also showed that the local variety excelled in the aforementioned traits with averages of (2.071%, 0.3926%, 1.6244%, 30.91 mg kg^-1, 53.447 cm, 194.29 cm², 342.2 g plant^-1 and 55.94 ton ha^-1). As for the interaction between the factors, it was significant in all the characteristics under study.

The experiment was carried out at the Horticulture station in the Al-Hindiya district / Karbala governorate during the 2023 growing season, using a Randomized Complete Block Design (RCBD) with three replications. The study aimed to investigate the response of two orange Cultivars (Blood and Navel) to spraying with the growth regulator brassinolide at three concentrations (0, 0.3 and 0.6 mg L^-1) and the addition of organic fertilizer (Humzinc) to the soil at three concentrations (0, 0.5 and 1 g L^-1). The results showed the superiority of the Blood Cultivar over the Navel Cultivar in stem length, stem diameter, Leaves number, root length, and root volume, while the Navel Cultivar excelled in leaf area. Treatment with brassinolide at a concentration of 0.6 mg L^-1 or the addition of organic fertilizer at a concentration of 1 g L^-1 resulted in the highest significant increase in stem length, stem diameter, Leaves number, leaf area, root length, and root volume. Regarding the interactions between study factors, the binary and ternary interactions had a significant effect on improving vegetative and root growth Traits. The ternary interaction treatment (Blood Cultivar + brassinolide 0.6 mg L^-1 + 1 g L^-1) outperformed by giving the highest average increase in stem length (35.98 cm), stem diameter (7.993 mm), average Leaves number (117.66 leaves seedling-1), root length (120.67 cm), and root volume (52.33 cm³), while the treatment (Navel Cultivar + brassinolide 0.6 mg L^-1 + 1 g L^-1) significantly excelled in leaf area (38.57 cm²).
