Abstract

In this study, the productivity of the red watermelon (Citrullus lanatus) crop in arid regions with saline water is examined in relation to the effects of magnetic treatment of irrigation water. The greenhouse experiments compared two treatments (magnetic treatment of irrigation water) and (no magnetic treatment of irrigation water). Magnetic treatment device delta water with a power of 14500 gausses (1.45 T) that was delivered from the company professional hydraulic (CPH) was used for vegetative traits on growing periods and quantitative, qualitative, and chemical production characteristics at maturity. The leaf area and the number of seedlings treated with magnetic water (MW) increased significantly by 8.7 and 1.4%, respectively, compared to control seedlings. Leaf holder length also decreased. Except for plant height prior to branching, it also demonstrated a notable increase in stem characteristics. Magnetic water (MW) enhanced the yield characteristics (quantitative, qualitative, and chemical), resulting in increases in the number of fruits produced per plant 11.4%, fruit weight 2%, the weight of a kilogram of seeds, and yield, respectively with 0.34, 10.34 and 16.5% decrease in fruit peel thickness. Additionally, it revealed that the sugar content had increased by 15.4% and that the acidity and electrical conductivity (EC) had changed. By adding magnetic treatment to irrigation water, fruits ripen earlier and have better texture, traceability and homogeneity.

Key words:  Magnetic water, Citrullus lanatus, productivity, irrigation.
