EXTENDED ABSTRACT

Introduction

Given the increasing population and the growing demand for food, agricultural development is essential. Due to the limited water resources, effective water resource management in agriculture is of great importance and must be considered at all stages of agricultural production. On the other hand, water resource limitations pose a challenge to agricultural development, necessitating a strong focus on the optimal use of available water resources, including unconventional waters. Magnetized water is one of the methods used to improve water and soil quality.

Materials and Methods

The experiment was conducted in a factorial design within a randomized complete block design with three replications. The irrigation factor was tested at three levels (100% FI (I1), 80% FI (I2), and 60% FI (I3)), and water salinity at three levels (well water (S1), 20 mM sodium chloride (S2), and 40 mM sodium chloride (S3)) in two conditions: non-magnetized (W1) and magnetized (W2) water. This study examined the effects of irrigation levels, salinity, and the type of irrigation water on the qualitative properties of strawberry fruit, including total protein, chlorophyll a, chlorophyll b, total chlorophyll, total soluble solids, titratable acidity, vitamin C, and sugar content.

Results and Discussion

The analysis of variance results showed that all factors had a significant impact on the qualitative properties of strawberry fruit at the 1% probability level. Among the different irrigation levels, the highest amounts of total protein, chlorophyll a, chlorophyll b, and total chlorophyll were 5.09, 2.39, 1.05, and 3.44 mg per gram, respectively, in the 100% irrigation treatment. Among the different salinity levels, these values were 5.13, 2.49, 1.11, and 3.61 mg per gram, respectively, in the well water treatment. Furthermore, the highest levels of total soluble solids, titratable acidity, vitamin C, and sugar content were 13.67%, 0.67%, 31.17 mg per 100 grams, and 36.49 mg per gram, respectively, in the 60% irrigation treatment. Among the different salinity levels, these values were 13.82%, 0.69%, 31.65 mg per 100 grams, and 37.04 mg per gram, respectively, in the 40 mM sodium chloride treatment. Magnetized water also had a significant effect at the 1% probability level on the qualitative properties of strawberry fruit.

Conclusion

Overall, the increase in electrical conductivity in the nutrient solution led to reduced water uptake and thus decreased its osmotic potential, resulting in lower product quality. Finally, due to the observed positive effects on qualitative properties, it is recommended to use this method for producing high-quality products with greater nutritional value in cultivation systems. Additionally, to reduce the negative effects of salinity on plants, a combination of magnetized water and regulated irrigation levels is suggested. This combination may help mitigate the negative effects of salinity while simultaneously enhancing water productivity in agriculture.
