This study aimed to determine the effect of electrocution with magnetized water on the seed germination and seedling growth characteristics of Acacia cyanophylla. The seeds exposed to electrocution with magnetized water at low magnetic flux levels had different exposure durations using a device designed for this purpose. The parameters were zero × zero, four amps × zero, four amps × 500 gauss, four amps × 850 gauss, and four amps × 1100 gauss, while the exposure durations were four, six, and eight minutes. The experiment occurred in a randomized complete block design (RCBD) with three blocks. The results showed that treating A. cyanophylla seeds with an intensity of 4 amperes × 850 watts in all exposure periods displayed a significant increase in the seed germination ratio (60.00%) compared with the control treatment, recorded with the lowest germination ratio (37.77%). For growth characteristics, the treated seedlings with four amps × 850 gauss for four min emerged with the highest seedling height, dry weight, and shoot diameter, compared with the control treatment providing the lowest rates for studied growth traits.

Key findings: Treating Acacia cyanophylla seeds with an intensity of four amps × 850 watts with four min exposure time showed a significant increase in germination percentage. It was excellent over all other interactions in most traits.
