The present invention relates to a liquid composition for promoting plant growth, which contains titanium dioxide nanoparticles. The composition contains, as a main component, an aqueous solution containing titanium dioxi de colloids. The titanium dioxide nanoparticles have such a particle size that they can be readily absorbed to plants. A pH of the aqueous solution is adjusted in order to prevent rapid precipitation of the titanium dioxide nanoparticles in the aqueous solution, before the aqueous solution is dilute d with water such that titanium dioxide has a desired concentration. Also, the composition contains adjuvants necessary for plant growth and a surfactant f or dispersion. The composition allows crop yield to be increased by increasing the photosynthetic efficiency of plants, and permits increasing the bactericidal activity of plants against plant pathogens. Furthermore, the composition permits improving a problem of environmental contamination cause d by the excessive use of biochemical fertilizers, and also contributes to an increase in farmer income.
