“Megafol” was classified as a plant therapy product. It is used to enhance the resistance of the plants to stress and increase crop yield. Four rice varieties as zhongzheyou1, chunyou84, chunjiang119 and zhongzheA/R5 were selected as materials. Foliage application was conducted at three stages: one week after transplanting, active tillering stage and full heading stage, respectively. The results indicated that“Megafol” increased rice yield by 6%~16% based on significantly increased the total fertile grain number per plant. Further study showed that the yield enhancement be derived from an increase of chlorophyll content and photosynthesis rate of flag leaves.“Megafol” had no significant effects on 1000-grain weight, seed setting rate, plant height, roots system activity and rice cooking quality.
