Investigation of the Reaction of Potato Plant to Magnetized Saline Water

Potato is one of the important agricultural products of different regions of Khorasan Razavi province, especially Quchan. The area under potato cultivation in the 2018-2019 crop year in this province was 4979 hectares and its production amount was 163151 tons with an average yield of 32.8 tons per hectare. In order to investigate the reaction of the potato plant to magnetized water, an experiment was conducted in Quchan city, Khorasan Razavi province. This experiment was performed with two types of water, "magnetic water (MW) and Tap water (N-MW)". Fertilization was performed based on the soil test. Row distances (130 cm) and planting distances (20 cm) were in accordance with local customs. The type of drip irrigation was tape and the distance between the drippers was 25 cm. During the growing season, the necessary measurements were performed to determine the important growth factors of potatoes and the effect of magnetized water on them. The EC of saline water was equal to 4.5 ds/m. The results showed that the use of magnetic water compared to the control (N-MW) on the yield of potato tubers was significant at the level of 5% probability. The results of mean comparison showed that the yield of potatoes under the effect of magnetic water treatment (25.4 tons per hectare) was about 30% higher than the control (19.4 tons per hectare). In general, magnetizing saline water significantly increased yield, quality, freshness, germination time, volume and weight of tubers, number of tubers per plant, reduction of weeds and reduction of crop pests.
