In this paper, the direct effects of gliding arc discharge (GAD), dielectric barrier discharge (DBD), and argon plasma jet (APJ) discharge as generators of reactive oxygen and nitrogen species (RONS) on wheat seed yield have been evaluated. This evaluation was studied for a period of eight month in fall planting. The plasma-activated water was used for irrigation during this period. Physical quantities of the plant, such as length, weight as well as panicle length, neck diameter, weight, number of seeds per panicle, and grain weight were measured and appropriate comparisons were made on the measurements. The results indicated that cold atmospheric pressure plasma increased plant length and biomass. Moreover, the length and diameter of the panicle was also increased which caused the in relative increase in number and weight of seeds. Therefore, it can be claimed that cold plasma has a positive effect on the growth and reproduction of wheat.
