Does an electric field affect plant growth?

Yes, an electric field affects plant growth. In the presence of an electric field, the height of the stem and the length of the roots are more than those without an electric field. The change in growth rate depends on electric field, temperature and humidity. Experiments show that if an electric field intensity of 25 kv/m is applied and temperature and humidity are controlled at 28 degree Celsius and 65% respectively, then the height of the stem increases by 24% and length of roots by 33%.
