This research was carried out at the olive grove cultivation center of the Directorate of Agriculture located in Tel Minin area in Rural Damascus, Syria in 2016, to inve^igate the effect of three levels of magnetic field 0.09 ‘0.06 and 0.03 Tesla on the chemical and physical properties of water and plant productivity indicators.

Draja potato tubers were planted, a drip irrigation sy^em was in^alled and the water requirement for the plant was determined using Class A basin.

According to the results, water quantity for irrigation and irrigation intervals were determined.The effect of magnetic field on the chemical and physical properties of water has been inve^igated and the following results were obtained: The exposure of water to magnetic field of 0.09 ‘0.06 and 0.03 Tesla showed a significant decrease in the electrical conductivity of water 14.07%‘13.70%‘11.85% respectively over the non -magnetized water.

The exposure of water to magnetic field of 0.09 Tesla‘ 0.06 Tesla resulted in a significant decrease of surface tension by 0.1 N/m ‘0.21 N/m respectively over the non -magnetized water.

while there was no effect of water exposure to 0.03 Tesla of magnetic field on surface tension of water.

The magnetic treatment of water affected the productivity indicators of the plant.

The exposure of irrigation water to magnetic field of 0.09 , 0.06 , 0.03 and 0 Tesla resulted in an increase in the growth rate of tuber germination, where germination rates were 93.33%‘ 86.67‘% 80‘% 73.33% respectively over the non -magnetized water, 20 ‘21.5 ‘22.5 and 22.5 days of planting respectively over the non -magnetized water.

The exposure of irrigation water to magnetic field of 0.09 ‘0.06 and 0.03Tesla has significantly increased the plant productivity by 27.24% ‘15.84%‘ 4.34% respectively over the non -magnetized water .
