Project

Effect of electricity on plant growth

The purpose of conducting this science fair project is to find out how electricity affects the growth of plants. The experiment is to be done by supplyingvolts to the soil containing radish seeds and observing the rate of plant growth.
Hypothesis
Radish seeds that are induced with higher voltages grow more quickly.
Overview
Electricity and plantsElectroculture involves the study of the effects of electricity and electric fields on the rate of seed germination and plant growth. This is an area of science where a lot of experimentation is beingconducted. Researchers are starting to find evidence that plant growth can be enhanced by taking advantage of the sensitivity of plant cells to electric currents.

Observations have been made thatcertain types of grass appear healthier after a thunderstorm and grass that grows below an electric power cable generally look greener. However, these observations have been disputed by skepticsclaiming that grass appear healthier after a thunderstorm as they have been given a good wash by the falling rain. As for the grass that grows under electric power cables, skeptics allege that the droppingsfrom birds that sit on the power lines act help fertilize the grass.

Certain scientists suggest that while plants need all the known conditions such as sufficient sunlight, air, water andnutrients to grow, the presence of an electric current help to enhance plant growth. However, if the other conditions are not available, the presence of an electric field will not make a difference.Materials
