The application of cold plasma has attracted considerable attention in the field of agriculture. We examined the effects of plasma irradiation and treatment with plasma‐activated Ringer's lactate solution (PAL) on rice seedlings in a paddy field. Irradiation during the vegetative growth period increased seedling growth, panicle number, and grain yield. In contrast, treatment during the reproductive growth period had a negative or no effect. Moreover, treatment with PAL solution promoted the growth of the main stem, such as grain number and panicle weight, and grain quality, but the grain yield from the whole plant was decreased. The results suggest that cold plasma treatment of rice seedlings is effective for improving plant growth, grain yield, and grain quality.
