sugar beet yield and quality characteristics as affected by magnetic field and silver nano particles

in order to study the effects of magnetic field, silver nano particles and micronutrient fertilizers on sugar beet, an experiment was conducted at razavi research and technology institute, mashhad, iran. experiment carried out with seven treatments based on randomized complete block design with three replications. treatments included (t1) magnetic field and silver nano particles + kemira fertilizer (t2) magnetic field and silver nano particles + humax fertilizer (t3) magnetic field and silver nano particles (t4) kemira fertilizer (t5) librel fertilizer (t6) humax fertilizer and (t7) control. the results showed that exposure of sugar beet with magnetic field and silver nano particles (t3) increased root yield about 43 percent more than control. magnetic field and silver nano particles stimulated shoot yield twice more than control. magnetic field + silver nano particles treatment showed the highest sugar yield (12.71 ton/ha) but t4 and control treatments showed the lowest sugar yield. experimental treatments had no significant effects on root quality except potassium content. it is expectable that magnetic field and silver nano particles could be suitable as an alternative for chemical fertilizers to reduce their application.
