摘要

Research was done to observe the magnetic field effect on root characteristics in sunflower crop raised from seeds exposed to the 200 mT magnetic field for 2 h. Treated seeds were grown under three different irrigation treatments at research field of ICAR-IARI, New Delhi, India along with control. Outcomes of the study exhibited that in treatment, plants had enhanced total root length, root surface area, and root volume in various development stages of the crop. Crop yield per volume of water supplied (water productivity, WP) had significantly more value in treatments than the control. The difference was higher in crop having less irrigation as compared to more irrigation in treatment than the control. Treatment had improved seed yield by 3 to 9% than control. Hence, sunflower seeds treated by 200 mT magnetic field for 2 h before sowing enhanced root growth, resulting in better water productivity and seed yield.
