The Effect of Irrigation with Treated Magnetic Effluent on Water Productivity of Maize

Water scarcity, the reduction of very high costs for the development of new water resources and the protection of the environment necessitate the use of unconventional water in agriculture. These waters include two main groups of effluents and saline waters, the direct use of which causes environmental problems and soil pollution. One of the ways in which water and soil can be improved and the total amount of water used for irrigation can be reduced is the use of magnetic water technology, which increases crop yield per unit volume of water used. In this study, the effect of using treated magnetic effluent on maize water productivity was investigated. For this purpose, a factorial experiment was conducted in a randomized complete block design with three replications in 2020 at Babolsar city. Treatments include irrigation with well water (W1), irrigation with mixing 25% of effluent and 75% of well water (W2), irrigation with the mixing of 50% of effluent and 50% of well water (W3), irrigation with mixing of 75% of effluent and 25% of water well (W4), irrigation with 100% effluent (W5) under magnetic field (I1) and without magnetic field (I2) was. The results showed that the effect of irrigation type and water and wastewater mixing on biological, physical, wet and dry forage productivity was significant. On average, irrigation with magnetic effluent significantly increased biological (10.33%), physical (9.35%), wet forage (10.07%) and dry forage (11.49%) productivity compared to non-magnetic effluent. Also, all the mentioned parameters increased with increasing the percentage of effluent used in irrigation. Using magnetic technology, effluent can be used to increase the productivity of maize.
